Toshiba satellite pro A60- PSA65E doesn't detect a hard disk
Hi to all,
There is a Toshiba Satellite pro A60-PSA65E, when i boot it up, it doesn't boot from HDD, i changed the boot sequence starting from HDD, nothing helps, when i go to the BIOS, it is not there(it is not detected). I tried to replace with another HDD, still the HDD is not detected, i tried to set default values in the BIOS, still no changes at all.
Anyone has an idea how to solve this problem?
Thanks in Advance

Reseat the HDD and if you still can't see it in the BIOS, it may very well be dead.

If it is seen in the BIOS, and, you just can't boot off it your OS might be corrupt. Run a repair installation if possible.

mood, change the HDD. if still it can't be recognized, this is southbridge failure(typical problem for this series of toshiba laptops)

...Is everything the result of a defective southbridge?

AFAIK, inspiron 8000 is Pentium4 based laptop.... so, 82801CAM(or 82801DBM) is your problem.

Lol, no thanks I'll spare myself of your propaganda. The only thing I can't understand is how people take you seriously.
