Hello.

I'm getting this:
> kernel: UFS /dev/da0 (/mnt/HD) cylinder checkhash failed: cg 18, cgp: 0x5b68e98 != bp: 0x352516c

Does it mean the USB key is broken and I can throw it away?

I can write to it, unmount it, but when I try to mount it again it gives:
> mount: /dev/da0: R/W mount on /mnt/HD denied. Filesystem is not clean - run fsck.: Operation not permitted

  bye & Thanks
	av.
