I can't get anywhere. I have a 160 GB pushbotton external hard drive, seagate brand, connected with a 2.0 USB. It worked fine, then all of a sudden when I tried to open it all I got was an I/O device error. At first people told me this was a registry problem, but when I tried plugging it into other systems the same error popped up. Strangly, the drive used to read E, but now reads as G. I don't think this is entirely the cause of the problem though, because when I tried plugging this into other systems it read E, but still with the same I/O device error. I have Windows XP on an HP notebook, and I am clueless. I tried disabeling the device, re-enableing the device, uninstalling the device and reinstalling the device. I tried a registry cleaner but it only cleaned 50 problems. I purchased a new cable and that didn't work either, and plugged both cables into all 4 of my USB ports. I bought System Mechanic 7 Professional, only because I live in a small town and Wal-Mart is the only place to buy software.
Is there a solution? Does any one know what an I/O device error means? Can I retrieve my information? I'm willing to drive very far and buy very expensive software to do this, so please tell me if there is any software that can help. Also, please tell me if there is any basic thing I can do to help.

It has nothing to do with the registry and it doesn't matter what drive letter windows assigns it. It sounds like something corrupted the file system on the external drive. That's why you're getting an Input Output error.
What is the exact error message?

G:// is not accessible.
The request could not be performed because of an I/O device error.

This occurs when I try to open the drive.

That drive is corrupt for one reason or another. If you want to take a long shot, you may be able to mount the drive on a Unix box or try something like the Ultimate Boot CD.
Also, you could search for data recovery software, in which I don't have much faith, but who knows?

Well that was the answer I was sort of fearing and expecting as well. Is there any way I can wipe the hard drive to make it useable again?

I just thought of something. I never tried it on a external drive but you might try the manufacturer's diagnostic tools. In most cases, you can d/l them from their site and create a boot disk. Boot the machine. If it sees the drive, run the tests on it. It may have a repair option.

HI
I have the same problem I got I/O device error when I try to transfer file form my external HD to my computer. it happen to any computer.
So I guess the Ext HD is the problem.

I run Regcure and follow protocol (ATA/ATAP en PIO Only) to fix this problem but nothing.

I have a lot of stuff on my ext HD so how can I fix my ext HD.

thanks

I believe I stumbled upon a fix to this and just wanted to go around making sure people know how to fix this ridiculous problem.

open up the cmd prompt

I haven't had this happen with Win 7 so I'm not sure about that one

older version of windows select RUN from start menu and type cmd

from there type "chkdsk X: /f" no quotes and replace X with whatever drive it is.

It should perform a scan and once complete should work just like new!

YAY!!!!!!

Peace, Love, Harmony

Dear cmd solution expert: I tried your solution, typing the following: chkdsk E: /f (By the way, what does the "f" stand for?)

Unforunately, I received an error: "Cannot open volume for direct access."

I tried using this command when the external drive was plugged into my laptop's USB port. I also tried it when it was not plugged into the port.

My issue still persists...My external drive cannot be read on account of an error when I attempt to use any one of the four USB ports: "E:\ is not accessible. The request could not be performed because of an I/O device error."

Any further assistance would be appreciated. I'm not prepared to buy a new laptop and I cannot replace the data that is on my drive.

Thank you.

Hi, i have a 4gb memory stick. When i connect it to my laptop, "my computer" starts to not respond. "I:/ is not accessible. the request cannot be performed because of an I/O device error" comes up when I try to go into it. I have run a scan on it already but the result was tat there was no infection in it. Is there any way this can be fixed, preferably without formatting it?

I was having the exact same i/o device error problem with my 1TB iomega external hard drive.
This is no joke but i fixed the problem by picking the hard drive up and shaking it and turning it on upside down..... it seems to be working just fine now, seriously! Give it a try

I was having the same problem with a new SD 4Gb memory card. After using the cmd prompt suggestion, still having problems. I was trying to use a small portable card reader (like a flashdrive). With a little more detective work I noticed that the newer, higher capacity memory cards are actually in a SDHD format. Very similar, but not recognized by my reader. Easy fix: use a reader which includes the new SDHD format. Good Luck!!!

Hi.

I am having the same I/O device error with my 250GB Seagate portable HD.
Here are what I have tried so far:
1) Did a virus scan only to find the device virus-free.
2) Plugged in to 2 computers (on different occassions) but experienced the same error.
2) Tried to fix the issue using the Device Manager method found on this website: "How to fix I/O Device Errors Step-by-Step" on Squidoo. Am not sure if I selected the correct device but the I/O device error still persisted.
3) Tried the cmd method but the chkdsk was aborted for some reason(Please refer to PrintScreen attached).
4) Can't find the Registry Cleaner on both of my computers - Window XP & Windows Vista.

Any advices would be greatly appreciated.

Thanks in advance! :)

I joined this community just to thank IcaseI. I did exactly as he mentioned..and it worked.
I've a 250GB WD external drive. It wasn't reading. It was making those clicking sounds right after being plugged in. I disconnected connected it a 50 times at least. I checked on many forums.All suggested a checkup at some computer center. I had some 100gb of data..and all work. I was thinking how much would i spend..would i get the data back.blah. And then i came across this forum..and IcaseI's post.
And it works!
Yay!
THank you!!!!!!!!!!

Hi, I may have a silly solution - I am no techie so apologies if this does not work for you.

I had an I/O error too with my usb key. I couldn't reformat the key, open it, view files etc.

I tried all the solutions above incl chkdsk etc but that failed too.

Then by chance as a last measure of desperation, I tried the USB key on my girlfriend's computer (Vista, like mine) and the key worked immediately and perfectly!!

I then put the USB key back in my PC, and it started to work (and continues to work) perfectly!!
The USB key in question ia a SANDISK Cruzer Sync 8GB Titanium.

Hope this works for you.

Regards,
Tony

Same thing happened to me with a 7 in 1 card reader usb 2.0..

It would only make sense to me the following.

It works with my 2gb card and my 1 gb card. but not with my 8 gb card.. I can only guess this is because the card that does not work is a category 6.. And the reader is only compatible with the older slower cards. Or 8gb is too large.. TO me obsolete is the tell tale signs.. I would simply rather buy another cheap usb stick or something.

What is an I-O Device Error?
The I/O device error means when your computer is not properly responding while reading the data while installing a program or even when you are copying data from CD to DVD drive. This error is more likely to happen when you are trying to transfer the data which your CD cannot use or don't recognize.

Some steps to solve the I/O device error:

o You should check for defective Disc in your computer:
You will generally get this message if your CD disc is dirty. You should take out the disc from the CD drive and check for any fingerprints or dust accumulated on the drive. Clean with soft cloth or wipe both the inner and outer sides. Try again after cleaning the disc.

o You should now check for defective drive in your computer:
This problem is seen sometimes when there is a problem with the drive. As it is not able to read the disc. For testing your drive you can take some CD's, which are working and if you get the same message of error then your CD drives needs to be repaired or cleaned. You can try to run the CD on anothercomputer if it runs their then there is problem with the drive.

o You may be trying incorrect transfer mode:
It may not be able to read the CD because of incorrect transfer method .You may need to alter some IDE properties.

o You should always check for loose cables in your computer:
First you should turn off your computer and check for wiring and connections of hard disk and the CD. Try to remove and reconnect them and try to copy the files again.

o Always keep updated CD drivers:
You should always keep updating the CD drivers, if CD drivers are old then the operating system won't be able to read it. For updating your CD drivers you can go to it websites and download the latest CD drivers.

IcaseI thank you...thank you...thank you...this scan disk worked perfectly!!! I still don't believe it. I've had this external drive that has been a paperweight for 3 months just about ready to trash it and I came upon your forum entry. I totally did not think it would work, boy was I wrong. This is why forums and people submitting thier own experiences are sooooo important!! Thanks again,Kevin

P.S. someone asked what the "f" was for it's for "fix"
