" Q. Toshiba doesn't provide a recovery disk with this laptop and I'm sure
not spending $20 to have a "free" one sent to me. I did notice that there's
a 1.5 gig hidden type partition on the hard drive. Would this contain the
recovery information by chance? If so, how do I access it so I can reload
my laptop?

A. To load the recovery partition, hold down zero when you turn it on. You
can also go to the recovery environment by tapping F8 when you turn it on
and going to Repair Your Computer. There will be recovery options there and
one is Toshiba Recovery Wizard.

If you still need assistance, please feel free to post a new message or
contact the Toshiba Customer Support Center at 1-800-457-7777. "
