    Default Erasing Casper / Persistent Reset

    Hi Everybody. Is there a way to erase the data that's been stored on a persistent USB, without deleting all of the partitions / BT4 OS and all that I've set up nicely?

    A friend mentioned that I might be able to delete the casper folder, any thoughts?

    boot up using your bt4 dvd.

    after getting into bt4 plug in your usb flash memory (the one with bt4 on it).

    use this command:

    mkfs.ext3 -b 4096 -L casper-rw /dev/sdb2

    this is assuming your usb stick is identified as sdb. this will format your casper partition and you get your distro as good as new.

    btw I'm a linux noob but it is clear that formatting your casper parition is the way to do it. if anyone knows a way to do it from within bt4 thats on the flash then that would be faster than using the live dvd.

    code1101 - Thanks for the tip, I think I'll give this a try, it makes sense to me that to just format this partition should work, though I'm a noob as well. GRUB should still be set, the normal (non-persistent) BT4 on partition 1 should be fine and all I'd assume.

    I'm just hoping that any of the tinkering I've done over with my persistent install hasn't changed anything on partition 1. That is, I'm hoping by formating the casper partition that BT4 will boot into persistence once again with all the defaults set.

    I'll let you know when I get the guts to try it, for now I'm going to see if selecting one of the other options in GRUB boots BT4 with defaults. My setup is essentially this one: Backtrack 4 – USB/Persistent Changes/Nessus but without Nessus or TrueCrypt
