I accenditally fsck'ed an Apple UFS partition with NetBSD's fsck.
(without the -a option)

At first I didn't underdtand why it spewed so many messages, but the
net effect is that fsck actually converted my Apple UFS partition to
FFS. (and I can't mount it read/write under MacOS X anymore)

Is it possible to convert my partition back to UFS without doing a
dump/restore?

Thanks,
 Aymeric
