[COLUG] Is the drive dead or not?

After two extended offline tests...

The drive isn't dead. (So one question is answered...)

After mount -f /dev/hdf1 /storage the drive appears in the df and mount. 
but... hdf1 should be 40GB and it shows up as only 9.2GB (the same as 
hda2, aka / ) and the usage is exactly the same, too (696M). None of the 
files that were in /storage are present on ls -la /storage.

fdisk -lu /dev/hdf1 looks okay:
Disk /dev/hdf: 41.1 GB, 41110142976 bytes
16 heads, 63 sectors/track, 79656 cylinders, total 80293248 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/hdf1 63 80293247 40146592+ 83 Linux

So the partition table isn't hosed.

But I am definitely at a loss...
