A couple Things

[Justin Bennett]

Two things.

One: is there a quick way to erase a linux drive other than formatting. 
I have 107GB of user data (on several mirrored scsi drives) I backup to 
tape every night, before I do that I copy it to a Large harddrive so I 
can easily grab something from yesterday when our users blow it away. 
Right now I'm doin a \rm -r on the backup drive, but that beats the 
drive up pretty good and takes a while. I could unmount it, mke2fs -j 
/dev/sdb1, then remount it this would be quicker, is there an easy way 
I'm missing to clean a volume?

Two: Any easy way to supress Timestamp warnings from Tar? I know I'll 
get the answer fix the problem not the symptom, but these are user files 
systems accessed via samba, and I have no interest in being the PC time 
police.

Thanks!
