Hi, I will assist,
I'm sorry about your laptop issue. It looks like the hard drive is damaged, but we can check/confirm first. Was the laptop dropped or hit something? Do you see the hard drive in bios/setup menu? Are you able to take out the hard drive and then reinstall it securely, and check?
Remove / replacing the hard drive is pretty simple and it does not avoid warranty, so don't worry. Please see the simple steps/illustrations at the website below:http://aps2.toshiba-tro.de/kb0/CRU2903E90000R01.htm
If that does not work, it looks like you've gotten a bad laptop. But not to worry, Toshiba will do warranty repair, i.e., Toshiba will replace with a new hard drive for now:(800)(NNN) NNN-NNNN(toll-free) or(NNN) NNN-NNNNbr/>http://support.toshiba.com/contact
I'm really sorry again about the hardware (not software) issue; I'm sure Toshiba will repair it for you. If you need anything else, please let me know any time. Thank you,
Or if you have any other computer question/issue, please let me know. Thank you,
