How do I erase my hard drive on a IBM T30 and reload the operating system and drivers.

Get an install disk for the operating system you wish to install (Make sure your computer is able to handle that operating system first), then put the disk in and boot to the disk. If your computer is not set up to boot to disk first then you will have to go into the BIOS, usually F2 of F12 on boot (whatever says press to enter setup), then change the boot settings from there.

Once you are inside the installer for that Operating System, it will give you an option to erase the hard drive you are wanting to install the operating system on, and restart new. Just so you are aware, this will reformat and ERASE EVERYTHING on that hard drive, so make sure that you have anything you want saved backed up somewhere else.

Once that is done, continue installing the operating system and then your hard drive will be erased, and the operating system will be reinstalled.

If you were just looking to erase a hard drive, then you can go to my computer, then right-click the hard drive you want to erase, then click format. THIS WILL ERASE EVERYTHING!

Hope this helps!
