|If you have a Toshiba hard drive also you can perform a hard drive fitness test using the Hitachi program. Download it from another computer and create a bootable disk. Use that disk in the laptop to determine if the drive is failing.|
You can also enter the BIOS (setup) screens and verify SMART is enabled. If it is and the drive is failing you may get some information on the boot screens from SMART.
I would guess Toshiba should know their own product.
Tell us why you were restoring to factory condition in the first place. That explanation may help with a diagnosis.
