Basically, I was having various problems with my computer which culminated in a fresh install of Vista. However, *somehow* in the process of the reinstall one of my extra hard drives got reformatted. Suddenly it simply wasn't there, even though the drive was recognised at boot. So I went into Disk Management and apparently it has magically changed into an EISA configuration(!!??!). So it's there in disk management, but it doesn't show up in file explorer and all my data is, presumably, no longer on a file table.
Now, for other reasons, I was booting from a vista startup disk (yeah, I've been having issues, now solved) and when I file browsing in it (where it says "Load Drivers" to select your windows install) my spare hard disk was there, visible, and all my folders were present on it. So... they're not *gone*.
Any ideas on how to proceed?
