It’s annoying to see see the error message when you need to use the external hard drive. First of all, let’s take a look at one questions from a real user.

“I have an external hard drive that has worked fine for years. Now the hard drive won’t show up in My Computer, though it shows up under Devices and Printers – very strange! I have tried initializing the disk from Disk Management, but it won’t format and I keep getting ‘The request could not be performed because of an I/O device error‘.”

What may cause I/O device error to happen? Is there any safe way to fix the error without damaging the the original data saved on the external hard drive? This article will give you a good understanding of the I/O device error and show you how to use MiniTool Power Data Recovery software to retrieve the lost data for external hard drive files.

Part 1: What Is I/O Device Error?

Any time you receive the error ‘The request could not be performed because of an I/O device error’ it usually indicates that the external hard drive has met such a severe problem that you cannot access it for data reading, file transfer and edit. You should be aware that the data stored on the external hard drive are at risk of getting permanently lost.

Some Reasons That May Cause I/O Device Error

* The device (external hard drive) has developed bad sectors. In this case, only certain files in certain sections of the hard drive platter will be affected.

*It’s also possible that the USB interface for the external hard drive is bad.

*If the logic board on the hard drive is bad, you will always get ‘The request could not be performed because of an I/O device error’. Unfortunately, the damaged hard drive is usually cannot be fixed by users themselves.

* The computer storage device driver is outdated, damaged, or the file system of the external hard drive is incompatible with your computer.

*The external hard drive, memory card or USB drive is recognized with a wrong drive letter.

* The Windows PC is using a transfer mode that is incompatible with your external hard device.

*The drivers need to be updated.

An I/O device error may occur on the external hard drive, flash drive, SD card, CD or DVD, etc. In general, you will get one of the following messages if your device suddenly gets the I/O device error.

“Only part of a read process memory request was completed” or “Only part of a write process memory request was completed”.

IO error codes like error 6, error 21, error 103, error 105, error 131 and more.

“The request could not be performed because of an I/O device error”.

To lower the risk of losing important data on your hard drive, it is strongly recommended to transfer or back up the data before you attempt to fix the issue. If you want to tackle one of those errors above, you can try the effective ways as follows.
