I/O error after running defragmentation

[syan90]

Hi, I have an issue regarding my HDD that has been working fine till I defrag it.

It's an WD2003FYYS 2x and both have the i/o error after defrag.

I am running on Windows XP SP2 but, on Windows 7 pro it works fine....

How can it be on one os doesnt run good and the other one fine??

Hi there syan90,

This is a really strange issue. It may be a good idea to back up the data stored on the drives(as they are recognized by Win 7) until you sort this out.
When do you get this error message?(when trying to access them perhaps?) These should be non OS drives right?
I guess it may be a good idea to test both of them with WD's DLG tool: http://products.wdc.com/support/kb.ashx?id=8Grneu
You can run both short and extended tests.

Sometimes, I/O(input/output) errors are caused by faulty cables. So, it may be a good idea to attach the drives with different cables(both SATA and power ones) to a different SATA port.

Let me know how this goes,

Thank you for your reply.

I am trying now running XP on a seperate hdd fresh install to see if any difference is happening.
