fsck_msdosfs failing

[Ben Williams]

Hi all,

I've got a problem with fsck_msdosfs. My FAT32 drive came up with errors 
after a power-failure-induced reboot, and recommended that I run 
fsck_msdosfs manually. However, fsck_msdosfs fails:

# fsck_msdosfs /dev/ad3s1
** /dev/ad3s1
** Phase 1 - Read and Compare FATs
No space for FAT (Cannot allocate memory)#

I've tried googling for it and I can't find anything other than a bug 
being mentioned/filed for netbsd which is obviously related, but no fix 
was forthcoming.

Does anyone have any ideas how I can proceed?

Thanks,

  - Ben
