I've read a couple unresolved threads on this and have gotten no where, so here goes:
I installed a secondary IDE drive (160gb) and everything works swell. However, when the computer sleeps or hibernates and I wake it up, that second drive has disappeared, both from My Computer and Device Manager. I can rescan with Device Manager and find it again, but this isn't a practical solution. The drivers are all up to date.
This computer is a headless FTP server, and won't get enough use to justify letting it run all the time. I can wake it up via the network card to access it, however, the drive that I store stuff on is that second drive, and if it disappears, I obviously can't access the data on it remotely.
