So I decided to reformat my C: and reinstall Windows (XP) today, because hey, I didn’t have anything better to do. It all went smoothly, but even after I got Service Pack 1, my 160GB secondary hard drive (Windows itself is on an 80GB main drive) appeared as one 1GB partition in the front and 150-odd-GB of unpartitioned space.
Now, before this happened, it used to have a 1GB (FAT16) partition for a swap file, 130GB (NTFS) partition for storage, and the rest (roughly 18GB of NTFS) for storage of a completely different nature. I know Windows without SP1 can only see 137GB, but my motherboard (Nforce2 chipset) appears to see all 160GB, and it’s not like it wasn’t working before I reformatted.
I think what happened is that something screwed up the partition table, since all the data was there (and I’ve spent the past 5 hours rescuing it to various network shares so I can repartition). PartitionMagic would quit at the splash screen complaining about an invalid EZ-Drive setup, and I haven’t used EZ-Drive in years, so obviously it’s reading something it doesn’t like. Once I wipe every partition out, including the remaining 1GB one, it loads again.
When I first got this drive a few months ago, it did the same thing: I migrated my data, rebooted once, and suddenly bam I’ve got a 1GB partition and a bunch of empty space. PartitionMagic freaks out; I have to rescue and repartition. I didn’t reformat or anything then, even, so I can’t even figure out what thing I did caused it to go bad that time.
SO MY LONGWINDED QUESTION IS: should I unplug my 160GB drive if I ever reinstall Windows in the future, and plug it back in once I have SP1? What causes my partitions (except the very front one) to disappear? Do I have a physically bad drive?
ALSO: Should the BIOS be set to LBA or CHS? I thought it was LBA, but whenever I set it, the BIOS changes it to CHS after the reboot. Am I behind the times?
