It is entirely possible that Windows wiped out your primary drive at this point. Windows always needs to be installed on drive C (primary). > Now, in the original error, it complained about a bad > superblock which I fixed with mkfs.ext3 -S.

Much preferred is "e2fsck -b 4096 -B 32768" or similar. If it gets to the point where all of your superblocks are bad (which are distributed across your entire disk) chances are that the rest of the filesystem has been corrupted also. > The kicker of all of this is that fdisk sees the partition just fine > and reports that it is an ext3 filesystem with all the proper > attributes. That's because you did "mkfs.ext3 -S", which wrote a superblock on the disk. > see the partition though.

Failing that, you can use "strings" or some other binary editor to search for your data on the disk, and start copying out the blocks. This works OK if you have text data, much less well otherwise. > The other is just as important to me: Why did this happen?

Sadly, windows has the "feature" that if it can't read the drive it assumes it hasn't been formatted and proceeds to format the disk (saving you the effort of doing it yourself).
