Hello
I don’t think that the 30GB will work anymore on this unit.
The 30GB HDD is more expensive as this TE unit
Buy a new notebook
This is a Toshiba driver page:
http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp?service=EU
There you will find a BIOS version 5.3 form 17/12/02. You can upgrade the BIOS.
Maybe a 2GB will work but please understand 30GB is not possible!!!
