Yeah, gives the same output:

e2fsck 1.40-WIP (14-Nov-2006)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sda1: 39/26104 files (28.2% non-contiguous), 62530/104388 blocks

It did this before without the -f option. And I'm able to mount it fine
once the system's booted, which we were before as well. The real test
is, can we uncomment the entry in /etc/fstab and have it mounted on
boot? Will have to wait til one of of is onsite and able to deal with
any issues that come up if it doesn't boot correctly before we can check
this...

Thanks, Tom
