I recently tried to install lubuntu on an external hard drive and it had an error(just my luck).

I thought everything was fine, so I went to gparted to reset the partitions for use with Windows. It showed 3 devices even though all there physically is was 1 device. So I rebooted and now it wouldn't show up what so ever (this is a 1TB drive so I was kinda mad).

It wasn't recognized in Windows so I googled around for a solution, and came to the Ubuntu rescue remix. I read that I should do the command sudo lshw -C disk -short and this gave me a table and to my surprise there is no /dev/sda or whatever letter -- it's blank.

It does read that the drive is there and it has a "H/W path"(whatever that is) ; this path is "/0/a/0.0.0". Long story short, my drive is useless in now -- I'm a bit of a noob and don't know what to do from here. Is there a way to get my drive back in a usable state?

If this helps any (sudo lshw) :

  *-disk UNCLAIMED

check /var/log/syslog for the section where it detects that device? – psusi May 14 '13 at 0:56
Can you mount /dev/sg1 or /dev/sg2? Errors? – Takkat May 14 '13 at 7:48
sg isn't a valid disk device. Also please edit your information into your question instead of linking to pastebin in a comment. This is odd. You might try sudo -s then echo 3 0 0 > /sys/bus/scsi/drivers/sd/bind or maybe 3 0 0 1, and check dmesg after for any new information. – psusi May 14 '13 at 13:53

Try using Testdisk to find the drive. (Available as a download or on Parted Magic). You may be able to recover lost partition information and reset it to get the drive going again.
