MicroDrive Re-Do-Do

["Steve ][" <sc-ii@hotmail.com>]

I corrupted the partitions on CF on my MicroDrive somehow. So I
decided to connect the CF to my Windows XP machine, formatted it as
FAT, and then put it back in the IIGS and booted the MicroDrive floppy
disk.

The MicroDrive utility used to say the drive had 16 sectors per IRQ or
something, now it says there are 0. I set the DMA back to ROM3. I have
a ROM3 IIGS but couldn't tell the difference between the "Enabled"
setting and "ROM3". 

Anyway, I partitioned the drive and then booted my GS/OS 6.0.1 floppy.
When the Finder ran through the volumes it found, it found some of my
old partitions (eg, I had one named "VOLC" and it's there again).

What can I do to make sure this thing is completely "fresh"?

Thanks.
