Ok, this has happened twice now since installing Windows XP. It never happened with Windows 2000, but I'm still not 100% sure this is a software issue.
Here's the problem: I've had two different IDE devices "vanish". Rebooting has no effect; however powering off then back on restores them.
The first time this happen Nero crashed at 99% done, and since it had the burners tray locked I reset the machine - no burner in Windows. OR the BIOS.
The second time the main HDD (a 120GB Maxtor - yes, a POS drive if there ever was one) did the vanishing act. This time no Nero (well, NVE was making a DVD out of some DivX's, but neither source/nor target folders were on the Maxtor).
This of course FUBAR'd Windows quite nicely. Power off was needed to get the BIOS to recognize the drive again.
Now, the drives are on brand new IDE cables (not rounded ones!), and are both plugged into the mobo's (an MSI i865 Neo2) IDE controller. They are not on the same channel.
The PSU is rated for 400 Watts, which should be enough. The mobo has the latest BIOS and all of the latest drivers/firmware/patchs are installed.
So: anyone have any clue as to WTF is going on?!?
This system was (mostly) rock-solid under Windows 2000. And no, I *still* haven't reinstalled Linux
(no time, no disk space at the moment).
Soon to be proud user of Mandrake 10 (again!). SuSE 9 sucks!
