AFTER you copy what you can't lose off the drive, try the CHKDSK as noted in this discussion.
I/O Device error
I have a Dell GX240 running windows xp professional 40GB hard drive, 512 memory with pentium 4 processor. I have a Maxtor 250GB external hard drive where I store my music files at. I tried to do a disk cleanup on the external drive and all of a sudden when I try to open some of the folders I'm getting this error message.(see below)
g:\my music\shared folder\paul mccartney is not accesible
The request could not be performed because of an I/O device error.
It is not happening with all folders though. Just certain ones.
Can someone help me with this and where did I go wrong? Any help and suggestions will be greatly appreciated.
