I have an older Panasonic Toughbook with a bad drive, I want to know if I can install a Solid State Drive. The laptop only provides 3.3 volts. I have called Panasonic support and they state that there are no IDE drives anywhere in production that they can recommend. I have found a Japenese website page that discusses clipping a pin off an IDE drive or modifying the cable to prevent 5V from being used, however mine is a slightly different model. The original drive is missing pin #43, which seems to confirm the need. I tried a new Samsug drive (still has all pins and I have NOT modified the drive cable) whose specs suggested it should run off 3.3 or 5V but it does not show in the bios. (It did on the first boot but when I rebooted w/ windows install disk ready it has not shown since.) I can still put the old drive back in and boot but the old drive scratches and clicks. This is a Panasonic Toughbook CF-W4, sometimes referred to 'Let's Note' although this unit is only labeled as TOUGHBOOK.
