I have a Toshiba Tecra with a Matshita UJ-810 DVD/RAM unit. Windows XP SP1. It worked for the better part of a year. Then one day I started getting:
w:\ not accessible.
The request could not be performed because of an I/O device error
After some experimenting, I realized that I could look at DVDs, but not CDs.
Windows says the drive is in working order and nothing is wrong with it.
The only thing I did was try to use (unsuccessfuly) CloneCD a couple of times. After that, it’s never worked correctly.
Any ideas what could have been broken? I am sort of suspicious it’s some sort of software/config/or driver-related issue, not really broken hardware. I uninstalled CloneCD, but that didn’t help.
