Have had this problem myself in the past using KDE x86. Since i switched to GNOME x86 i have not had the problem recur. Also make sure you shut down BT correctly.
I was using a 8GB USB with 2048MB persistence.
Have two different usb drives and have tried multiple copies of Backtrack 5 yet keep having this problem.
Using UNetBootin (Universal USB Installer) Backtrack installs onto my USB just fine. I boot it up. Go online, mess around with settings. Then shut it down.
Now on the next boot up I get a error.
Error.Deleted inode refference 642614.
This cycles endlessly.
It must be a hardware problem or something.
16gb Transcend USB 3.0 bough specifically for this purpose. Fat32. Tried persistant memory at 4 gb then scaled it back to 2.5. Both Gnome and KDA. x64. (Can't remember if I tried the x84.)
I've reinstalled at least 4-5 times and it keeps happening....? ? ?
Using an Alienware MX17 with USB Renesa drivers.
