Try running a Live CD on that computer, then stick a USB stick into the connector and see if it is recognized. If not, it's a hardware problem with your computer. If you can make and use a Live CD of another distro (sidux, elive, whatever) that would prove it is unrelated to *buntu.

I doubt your prior devices are destroyed -- probably you can "dd" them back to life, if they can be recognized on the bus with a /dev/sdx number. You'll have to zeroize the MBR:


dd if=/dev/zero of=/dev/sdx bs=512 count=1

Don't make a mistake on the x -- this command will also zeroize your hard drive if you get the "x" wrong, so be sure before you issue the command.

Then you'll have to use GParted, Qparted, or some other partitioning utility to create a partition table, and then you can format it.
