[SH] Drive scrubbing script
« on: May 07, 2005, 05:55:07 pm »
I'm currently working on a pretty pretty drive scrubbing script in shell script.

I'll post it open-source when it's complete.

Sure, it's got the basis of the basic script I stole off of iago (for i in 1 2 3 4 5; do cat /dev/urandom > /dev/hda; done) but I made it pretty. It's mad sexy too.

Format so far for the command: ./scrub.sh <drive> <number of scrubs> <wipe with zeroes at the end>
Example: ./scrub.sh /dev/hda 3 yes (I may make the last parameter a 1 or a 0, just because I don't know how to do booleans with shell scripting)

If you forget a parameter (or just run it with ./scrub.sh) it'll prompt you for the parameters you forgot.

Sure, a useless waste of time, but if someone can sell a drive scrubber for $70 (iolo) why can't I release an open-source scrubbing script?!

(Well, the drive scrubber DOES run OS-independently, has a nice GUI, has lots more options, and gives you a time-remaining number, but you get what you paid for :P)

Another reason I'm doing this is so that I keep semi-fluent in programming/scripting. I haven't coded in forever^2 so I don't wanna lose all that skill because I don't want to program. :(

I'd bet that you're currently bloated like a water ballon on a hot summer's day.

That analogy doesn't even make sense.  Why would a water balloon be especially bloated on a hot summer's day? For your sake, I hope there wasn't too much logic testing on your LSAT.

Hmm, one of the live Linux distros I was playing with had a built-in drive scrubber.  I'll have to figure out which one.

Mmk. So far I've got three files.

scrub/scrub-dev.sh // The development edition! Optimized for testing, as it doesn't scrub your drive if you accidentally run it! :P
scrub/scrub.sh // The normal edition. Contains all colors, no comments, and will scrub your drive good!
scrub/scrub-naked.sh // iago comes to your house and scrubs your car naked. .. .. .. Just kidding! It doesn't have any colors! 400 bytes smaller than scrub.sh, half the size of scrub-dev.sh

Yeah! Woo!

Don't forget to make it bootable off a floppy or a cd with a minimal Linux kernel.  Have it display statistics afterwards.  And have it support SCSI (can VirtualPC emulate that for testing?).  If you do all those, I can probably convince them to try/use it at work.

It requires bash/sh to work correctly.

I'll get around to looking at that. :)

Well, things like Knoppix come with bash/sh.

But you can make a very compact Linux (or bsd) that fits on a floppy and is only useful for wiping.  It can even give a menu instead of making the user run the command.  :-)

Dead sexy.
I'd personally do as Joe suggests

You might be right about that, Joe.

Hold on, hold on, wouldn't

Code: [Select]
for i in 1 2 3 4 5 6 7 8 9 ; do cat /dev/urandom > /dev/hda; cat /dev/zero > /dev/hda; done
work better?

Are you going to release this any time soon? I want to try it on iago's harddrive. (No.)
