I/o Error Reading Files Hard Drive
mode that the operating system is attempting to use for the operation may not be recognized. The I/O error may be experienced with various media storage devices such as: external hard drives, DVD or CDs, DVD or CD drives, SD cards, or USB sticks/drives. Common causes of the error include faulty hardware, a loose connection between the hardware and computer, outdated hardware drivers, or the IDE channel properties require modification. What Are the Common I/O Device Error Messages? Unfortunately, the I/O device error can generated more than one error message. Some of the most commonly encountered messages associated with the error include: - The request could not be performed because of an I/O device error - Only part of a readprocessmemory request was completed - Only part of a writeprocessmemory request was completed Windows may display a “Windows error code” along with the plain language error message. The I/O device error codes that are associated with the error include: error 6, error 21, error 103, error 105, and error 131. Why Does the I/O Device Error Occur? There are a number of potential causes for I/O device errors on computers that run the Windows Operating System (OS). These include: - Outdated or corrupt driver installation for the affected hardware device. - Windows using an incompatible transfer mode for the hardware. - Faulty or loose connection with the hardware. - The portable media (CD, DVD, or SD card) is damaged or excessively dirty. Basic I/O Device Error Troubleshooting Before throwing away a “faulty” CD/DVD, or delving into more complex troubleshooting, there are some basic steps computer users can attempt to clear the I/O device error. If the steps do not solve the issue, they may help pinpoint what is causing the error to be thrown and save time in fixing the issue. Step 1 – Restart the computer that is throwing the I/O device error. Step 2 – Attempt to access the disk, drive, or portable media again. Step 3 – If the error is still being thrown, try to access the disk on another computer (if available). This will help identify if the error is
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. http://www.tech-faq.com/io-device-error.html 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 http://www.ozzu.com/hardware/device-error-for-external-and-flash-hds-t76874.html 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 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? mtg837 Born Posts: 3 3+ Months Ago 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. Don2007 Web Master Posts: 4923Loc: NY 3+ Months Ago 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? mtg837 Born Posts: 3 3+ Months Ago 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? Don2007 Web Master Posts: 4923Loc: NY 3+

When I plug it into any of my computers it usually will not mount. Occasionally, it does mount, but then when I run an ls command for instance nothing ever comes back. The drive is split into four distinct partitions, the biggest one, and the one that I would like to recover is a data partition of about 953 GB. When I run dmesg (on my Ubuntu Linux system) I get these errors, the clearest of which seems to be reporting an I/O error: Buffer I/O error on device sdc, logical block 131328 [1206389.681527] sdc: sdc1 sdc2 sdc3 sdc4 [1206389.684156] sd 15:0:0:0: [sdc] Attached SCSI disk [1206394.848541] usb 2-1.6: reset high-speed USB device number 6 using ehci-pci [1206399.728633] usb 2-1.6: reset high-speed USB device number 6 using ehci-pci [1206405.268562] usb 2-1.6: reset high-speed USB device number 6 using ehci-pci [1206411.428538] usb 2-1.6: reset high-speed USB device number 6 using ehci-pci [1206416.908592] usb 2-1.6: reset high-speed USB device number 6 using ehci-pci [1206422.864664] usb 2-1.6: reset high-speed USB device number 6 using ehci-pci [1206423.605712] sd 15:0:0:0: [sdc] Unhandled error code [1206423.605718] sd 15:0:0:0: [sdc] [1206423.605720] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK Does anyone know how I might go about diagnosing the problem here, and if at all possible recovering the data on this hard drive? Update: I decided to follow these instructions about recovering a bad superblock from a corrupted drive. That involved running the command fsck -b 32768 /dev/sdc4. When I did that, I go the following error. I'm not sure how to answer that: Data was not cleanly unmounted, check forced.
