What's A Good Transfer Rate For Usb 2.0 External Hdd ?

Just curious what a good transfer rate when transferring from the external drive -> internal drive via usb 2. 0 connection. I was getting 22. 5 mb/s according to vista when transferring from my external 5400rpm laptop hdd to my internal 7200rpm laptop hdd. Is that a good rate?

Difference In Transfer Rate From Usb To Usb And Hdd To Usb

I have an seagate 160gb external hdd (fat32), and i was wondering if moving the page file to the external disk would garner any extra performance gains. I was also wondering if there is a difference in the transer rate from the usb->usb and hdd->usb. I was thinking about using hdtach on my external drive, so i think i'll give that a try.

I have a usb2 1gb thumbdrive. I have 4 usb2. 0 ports on the back of my computer and 2 usb1. 1 ports on the front of my computer. When i plug my thumbdrive into the front or back i get the same transfer rate. Now i'm sure that's not suppose to happen. In my device manager i have, under universal serial bus controllers, intel(r) 82801eb usb universal host controller, have 4 of those, then i have one of, intel(r) 82801eb usb2 enchanced host controller. Any suggestions? I have xppro sp2.

Hdd Transfer Speed Over Usb

I keep on wondering how come my hard drives have such a low transfer speed with usb. I have a mybook and a usb docking station. Both of them cannot transfer past than 20mbs. When i switch back to sata, i get at least 3 times the transfer speed (more for my faster drives). Sata is faster than usb, i can understand that. But usb 2. 0's rated transfer rate is 60mbs, what exactly is throttling the speed?

Usb Cables For External Hdd

I have usb cables that came with a couple, can't remember if all, of my usb hdd enclosures that have, idk exactly what it is, some type of resistor, or something, the little cylindrical fitting that goes around cable next to plug, and i'm wondering what that accomplishes, and if it's necessary to have. Can i replace with standard usb cable or is it important?

Computer Cannot Detect Usb 2.0 External Hdd

My computer cannot detect my usb 2. 0 external hdd, it was working only a few minutes ago, then i removed it through "safely remove hardware" after that i realized i forgot something so i plugged it back on. The light of my external hdd is on, but my computer isn't responding, it isn't showing any signs of another hdd in "my computer" and also in the "safely remove hardware" thing. I tried in my other computer and it's the same. I've scanned through for viruses previously, and cleared 3 trojans. Shouldn't be of a problem tho. Is my newly bought external hdd faulty ? Or has my computer gone mad?

P/s i also got this common problem that my external hdd couldn't be read directly, i have to - rightclick - explore. I believe this is a common n00b mistake i have done to my hdd or something.

External Hdd, Sata Or Usb For Backup

Three pc's; two towers (both w/ two hdd's) and one laptop (not used often), not alot of data, but instead of using dvd's to backup, this seems easier, one device for all three would be nice, though the laptop i could live without, it would be used mainly for my main box (tower). Questions;
1. If i went with a usb interface, can i assume the ps is external?

2. Can i then assume most are those damn 'bricks' as opposed to internal ps's within the hdd enclosure?

3. Are there any models w/ internal ps's, or at least a ps that is on a cable so it isn't hanging from the power strip?

4. Between the all in one (hdd, enclosure & ps) vs buying the enclosure, ps and the hdd separately, what's the better route?

5. If i went with a sata drive, are there any enclosures that are tailored to this setup?

6. The cabling from the pc to the unit. Make shift or use a premade pci slot plate w/ connectors (assuming they are available)?

Disconnecting Usb External Hdd With Switch

I used to have an external hdd with a separate electrical outlet to power it and even though it was a little bulky but this design was comfortable to me because i'm always very interested to disconnect the drive after any backup i need by using a "power switch outlet" with on/off keys where pressing the button connects power to the drive and windows xp sees it and vice versa without any need to physically removing/attaching any thing. P. S. I do this to prolong the drive's lifetime and to keep it away from any possible problems occurring to my pc. Etc. Now this drive is dead for some reason so i went to buy another one but i was stuck with a usb powered drive (wd my passport essential) and it's ok but the only thing that teases me is that i can't control the power since it's usb controlled so the drive starts spinning when i turn on my computer's power switch so the only way for me to control this is disconnecting/connecting the usb cable with the port whenever i don't need/need the drive which is not convenient at all. Is there any solution (like a cable) which allows me to control the drive's status (on/off) with a simple key switch without the need to physically remove/attach the usb cable from the back of my machine so that whenever i need/don't need the drive, i simply switch on/off a key on this cable?

Running Application Projects Off Sd Card Vs External Usb Hdd

Due to space restrictions i was considering running an audio application (cubase sx 3) off an sd card on my in-built sd card reader of my nc6000 (or if that is shocking, run the app off my c: and store the files on the sd/usb drive. ) Anyways, the question is: with read speeds of 5mb a second for ubs hdds (worst case scenario) and a similar speed for sd card transfers, would you be able to run project files for this application from an external usb hdd or sd card (through inbuilt port) ?

Which medium would generally have a more reliable and speedy transfer rate (assuming i get a decent hdd/sd card)? Would it stutter and be too much for the memory to handle? I have 1 gb of ram in my laptop. I deal mainly with raw wave files of about 50-80mb playing back, with about a sequence of ten-twelve files playing back after eachother.

2.5" Usb 2.0 External Hdd Hard Drive Enclosure Problem

I have this generic 2. 5" usb 2. 0 external hdd hard drive enclosure and a 2. 5" wd ide hard drive. Recently, my brother was transporting some files downstairs and dropped it all the way down the stairs. After we plugged it back in, it came up and all, but it was very slow. So, i just left it. Now, (a couple of days later) i plugged it into the computer and the led on the enclosure come up and all, but windows will not install the drive. When it tries to install it, it just "fails". The enclosure always had this problem when plugging it into a front usb port and occasionally the back one. But, after a few tries on the back usb, it would work. Now, it just wont work at all. Another thing i noticed is that when the hard drive tries to rev up (spin) it stops and clicks, then starts again. This made me think the hdd was gone. Yet, i undid all the screws on the hard drive and (unsuccessfully) tried to open it. I then put the hdd in the enclosure and it still would not install, but the hard drive didnt make the clicking. It spun like normal (then slowed down when it didnt install). Finally, i put the screws back on and the clicking has returned. Any ideas whats dead/how to fix?

Usb 2.0 External Hdd Error Windows Delayed Write Failed

I purchased a western digital 40 gb, 5400rpm usb2. 0 external hdd(2. 5") recently and when i try to copy large cunk of data, windows gives me an error

"Windows-delayed write failed"
Windows was unable to save all the data for the file deviceharddiskvolume6. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file else where. But small chunks of data can be saved. Also when this happens, windows does not recognize the partitions of the usb drive and shows only one letter for the drive without any contents!

My pc's configuration is as follows:

850mhz celeron
256mb sdram
Internal 20gb samsung hdd(54000rpm)
Pci-to-usb - pci card fitted into pci slot(has 4 usb outlets)
Windows 2000 professional with sp4

I have no conflicts whatsoever with the usb drivers. One more thing; i have not faced the above problem when i try to transfer data from another system which is of a higher configuration than what i have mentioned above. This system's configuration is:
Windows 2000 professional service pack 4 (build 2195)
1. 93 gigahertz intel pentium 4
8 kilobyte primary memory cache
256 kilobyte secondary memory cache
512mb ddr-ram

Any fix?

Vhs To Hdd Transfer

I'm attempting to put all of my older vhs tape media on my pc's hdd. My vcr is older as it only has audio/video in and out rca jacks and of course a cable f-jack (believe that's what a normal cable jack is called), not even an s-video jack. My video cards are xfx 7800 gt's extreme editions in which i believe has vivo. Also i have a pvr-500 dual tuner tv card hooked up to my makeshift htpc setup. This might be the most feasible way to capture video from my vcr, but i'm a little sketchy on how to go about doing it.

Transfer Files From Virus Infected Pc To External Hard Drive

I have a trojan virus on my computer. I cannot (given my limited knowledge) remove it. I want to transfer music files from the infected computer to an external hard drive. The anti-virus program that detected the virus on my computer 'tells me' that these files are not infected. My question: what are the risks of transferring these music files to my external hard drive? I am concerned about the risk to the external hard drive itself and also to any computer that i might later transfer these files to. Wow, i hope i asked this question intelligently! Too long? More concise? More info? (I'm interested in the best way to phrase a question as i believe that being a good computer scientist is largely about recognizing a problem intelligently)

Good External Drive Under $50

I don't need a ton of room but i'd like a decent external for $50-60. Skimming newegg/amazon i see there is a re-certified western digital 250gb passport (blue) for $50, and a re-certified black one for $50 also. Not sure if i should trust re-certified hard drives. I like wd along with seagate but haven't kept up to date on externals. Is the quality any different or can i trust them as much as the internals? Wouldn't imagine they are much different. Anyway, here is a link to the one i had in mind. Please let me know if you recommend something else.

Cant Install External Hdd

Ive just put one of my "maxtor diamondmax plus 9 160gb ata/133 hdd (6y160p0)" - disks into a "techsolo tmf-3560" external storage case. The harddrive is jumpered as master, but i get the same problem when setting it to "cable select" and "slave". When i connect the case to my acer 5024wlmi with usb 2. 0 i get this error message:
"Found new hardware

A problem occurred during hardware installation. Your new hardware might not work properly. "
After that nothing happens. The device manager keeps updating, but doesent find or install anything. Cant find it in "disk management" either. Both my mp3-player and my usb-mouse connect without any problems. I use windows xp professional corporate, sp2 with all the updates (windows xp professional (5. 1, build 2600) service pack 2 (2600. Xpsp. 051019-1519)). I tried my external drive on my machine with win2003ent, and it worked just fine. But i get the same problem on my third computer also using xp pro corp sp2.

Changing Usb Polling Rate To 1000hz Or Lower

If your like me and hate default 125hz that all windows install (unless you modify) here is a quick way to change your usb polling rate to 1000hz (1. 00ms response time). Note: some mouses don't go all the way up to 1000hz. This is mainly in wireless mouses. Windows vista & 7 64-bit:-

1. What you need: - dimr.exe (direct input mouse rate). 2. Extract & dimr.exe into a folder. 3. Right click on "hidusbf. Inf" find install (if warning comes up about unsigned drivers don't worry). 4. Open up dseo13b.exe and check "enable test mode". 5. Reboot. 6. After reboot you will see "test mode windows xxxx build xxxx" you can get rid of this but for now reopen dseo13b.exe and check "sign a system file". 7. In the box type in "c:windowssystem32drivershidusbf.sys". If correct a window will come up saying "the system file has been signed succesfully. ". 8. Reboot. 9. Reopen hidusbf folder and click on "setup.exe". 10. Find your mouse click on it (it should be highlighted has blue) and at the bottom of the window check "filter on device" and select your rate. 11. Click restart and open up dimr.exe. If it's still runs default 125hz reboot your windows vista or 7 64-bit operating system again. 12. To remove watermark open dseo13b.exe and click on remove watermarks. It will link you to the website with the correct files to remove it. Windows xp/vista/7 32-bit:-

1. Right click on "hidusbf. Inf" find install, (note sometimes with xp if you apply and the mouse stops responding in this case restart again and try again). 2. Open hidusbf folder and click on "setup.exe". 3. Find your mouse click on it (it should be highlighted has blue) and at the bottom of the window check "filter on device" and select your rate. 4. Click restart and open up dimr.exe. If it's still runs default 125hz reboot.

External Usb2 Hdd Slow

Very Slow Usb Transfer / Detection

I have asus m3n78-vm mobo and it has some problems in it. I think my usb ports are not running as fast as they can. When starting windows it takes ages to detect my external hdd , buffalo drivestation 500gb usb 2, and transferring like 300 mb file from internal hdd to that external is pain in the ass slow. Transferring from external to internal it has no problems. Files fly from buffalo to my internal sata hdd. But if i try to move file from that internal hdd to external buffalo, windows says it takes about 10 minutes to transfer one 300 mb file and it does also take that long, so what a heck? Im confused. I checked bios and all usb 2 features are on in bios. I also had some weird io shutdown problems. Anyone has any solutions to this? My buffalo also has some turbousb feature but dunno if it works. Oh and i use 32 bit xp pro with sp3 in it. Btw my old mobo dfi lanpary nf3 ultra-d did not have this problem with my external hdds. I have also tried all usb ports, and its the same problem.

Mouse Dpi And Usb Polling Rate - Knowledge Base

Just thought id share with you some knowledge on the subject of (usb) mouse polling rates and how they can affect your online gaming (well, they wouldnt affect anyone elses now would they). Windows xp, being pretty trashy as it is, by default sets the windows usb polling rate at 125mhz thats an 8ms response time to me and you. What does this mean, well, this equates to lag! The bane of all counterstrike and alike players, and generally all good fps games. Now, what can we do about this, well, interestingly enough we can, depending on the quality of your usb mouse (i have a razer diamondback) you can increase the responsiveness significantly. The basics are, the polling rate determins the time it takes for an action performed on the mouse to be transmitted to your computer and thusly to the game/software your using, so this incorporates a slight delay (lag) into your responses within the game. This becomes more prenounced while playing online games where pings/latencies and rates also effect your lag or responsivness. This can mean the difference between a shotty between the eyes and getting that "god-like" voice sounding off in the background

Is i stated earlier the default polling rate is 125mhz (8ms) and so naturally we get quite used to this when playing games, but wouldnt it be far greater to eliminate as best as possible this delay in sending mouse commands to your games to give a more fluid and responsive control over your gaming? Id say *** yeah!

Right, there are a few different ranges you can use, and all are totally dependant upon your mouse's abilities, but none should harm your mouse (best have a ps2 mouse at hand incase yours aint up for the higher rate so u can change back to default), firstly: we have:-

125mhz @8ms response time (default)

250mhz @4ms response time

500mhz @2ms response time

And the highest so far:

1000mhz @**1ms** response time!

Right, i currently use a razer diamondback usb mouse, and have the polling rate set for 1000mhz, the actual polling rate is often fractionally lower than stated but pretty damn good. I have personally noticed improvements in the sensitivity and responsivness in my mouse, especially when playing online fps games. But there is an improvement to be had when playing singleplayer fps games and other games alike. I am providing a link to the software i used to patch my usb polling rate, and included is also a mouse polling rate detector to tell you your current response time. See the screenies. Just a note though. Once you change your polling rate you must restart windows for the changes to take affect. This can make games more enjoyable especially the online games, but it could also be that you just dont notice the difference, as in the case that your mouse only supports a marginally higher response time. But anything which reduces the amount of lag gamers suffer can only be a good thing. I will amend the post if i have missed something, but i think i got everything on here. As you can see from the screen shot the razer diamondback performs very well, often over 1000mhz, less than 1ms, but on average its more like between 700-900mhz, still a damn good improvement over 125. Here is a link to both the current mouse polling rate detector and the usb polling rate patch, neither created by me so i claim no glory here, other than i zipped them together in one handy package.

How To Increase Usb Sample Rate In Windows Vista Sp1 ?

Microsoft windows vista’s default 125hz usb sample rate is not enough for today’s gamers and end-users. There are many usb sample rate patches out there, but none of them are supporting windows vista sp1 - due to the new restricted driver signature enforcement feature. However, it is now possible to use these patches thanks to the latest version of our own driver signature enforcement overrider (dseo), but i am not taking any responsibilities for any damages! Use it at your own risk. 1. Download driver signature enforcement overrider (attached below). 2. Download hidusbf (attached below). 3. Run driver signature enforcement overrider and choose enable test mode. 4. Extract hidusbf to some folder, right click on hidusbf. Inf and choose install. 5. Run setup.exe from hidusbf’s folder, check the filter on device box and select your desired sample rate. 6. Run driver signature enforcement overrider again, choose sign a system file and insert full path to the installed hidusbf.sys file (usually c:windowssystem32drivershidusbf.sys). 7. Restart your computer and enjoy. 8. Verify by using mouse rate or directinput mouse rate (attached below)

That should do the trick. Remember! Use it at your own risk! Do not blame me if your motherboard explodes, vista or usb fails. But, i have already tested it myself with a lot of success, so you don't have any reason to worry. If you would like to uninstall it, just right click on hidusbfu. Inf, choose install and disable test mode from driver signature enforcement overrider.

External Hdd Do Not Get An Assigned Drive Letter

I've got a sql server that uses an external hdd to do backup/transaction logs. The drive specifically has to be the "i" drive in order for the scripts to run. All was working fine untill i replaced the 5 external drives with new ones. Same size, same brand, different enclosure. Now whenever i plug the drives in, they do not get an assigned drive letter. The only way the server will see them is if i go into "manage your computer" and then assign the drive the proper letter.

External Hdd Causing Reboot Loop

I had to reformat my computer from a corrupted file causing windows to not be able to boot. So i wiped both of my internal hdd's (two seagate 500gb 7200. 12 drives) and reinstalled windows xp sp2. After the reformat it would start to post and get to (or apparently slightly beyond) memory testing when it would restart the boot and get to the same point, etc. At first i thought it was a memory problem since it would get to memory testing so after a few days of trying different memory combinations i tried unplugging devices and low and behold once my external hdd (a wd my book essential 320gb) was unplugged the computer would boot just fine. I have found that after the computer is booted if i plug in the external then plug it into power my computer will recognize it. This is not a huge problem but it can be a little bit of a pain because i now have to do this every time i restart my computer since i use the drive to back up my files. Is there any way i can get this drive to be recognized at boot to avoid plugging it in every time? Or what is going on when it will not allow the computer to post?

External Hdd Enclosure Connected To 2 Computers

I have this external enclosure with usb and sata on the back. What happens if i plug it into two computers? I have it connected to a htpc but when it is being used to watch a movie (on a different drive), i wanted to do access some files on the hd without "safe removing" it from the htpc. Would it be recognized fine on the other pc? Corrupt files if being accessed or written at the same time? Do nothing? Disconnect itself from the first? Destroy the hd? Destroy the sata and/or usb port of the computers? The enclosure? Intelligently queue up requests from both machines?
