I have a dual hdd system - a Seagate 320gb hdd which contains the os and a further partition which is just used for general file storage etc and a second hdd, a western digital caviar 500gb which is used exclusively for media storage - music, videos etc. Thus the first hdd with the os vista home premium x86 is really very under utilised, since I pretty much only use the thing as a home theatre machine via Vista media centre (it's set up in the front room through 5.1 speakers & an lcd panel) Yesterday, I noticed that the tv pictures became unusually jerky & the internet connection was dropped. these are unusual events, so I opted for a restart to clear what ever was wrong.
The machine on reboot could only see the 2nd non os Hdd in the bios & absolutely refused to boot into windows. I tried new sata cables, force detecting the hdd & removing the 2nd hdd and a restore via the MS disc, all to no avail. Finally, at a loss, I rebuilt the os on the original hdd & fired true image over it, so more of an inconvenience than a disaster, but any suggestions on what may have happend are welcome, since I can't think why. Updates & avg all current.
