If it's mounted read/write you will get inconsistent result on an fsck.
Try doing it in single user mode.

I think in summary, though, the end result is that the 15 Megabytes/sec
that Amandeep was getting is normal.

ata100 is 100M*B*/s, not 100Mb/s. However, unless you are reading out
of the cache of the drive, you'll get a much lower speed (on the order
of 10-20MB/s I think from that generation of disks).

Hi Eric,
Shouldnt it be around 54MB/s for a regular IDE drive.

Anyway, i'm getting 50~60MB/s on my

So i think 15MB/s is a little slow.

Hi,
I was wondering why the limit for file system snapshots in BSD 5 has been
set to 20. Is it a limitation due to the way this feature has been
implemented?
