It's a Toshiba harddrive. And forgive me, but I don't even know what information I should note down....But, here's the best I can do:
Disk Drive MK1234GSX
HDD2D31 S ZK01 T
It's a 120GB HDD.
I really hope that's all the info I need.
If you could answer, I would be ever so grateful to you. Thank you for your time.
