Well I had a solidworks part open, autocad files, labview app, email and some other shit open on my desktop today at work. Took a walk over to the machine shop next door, picked up some parts and checked on the status of some other parts, came back to work with my dual monitors displaying please insert bootable disk. Reboot and same message, damn! so I changed sata data cables, power cable, etc... still the bios doesn't see the drive. Tried it in a different system same issue. I had the exact same make model hard disk in stock for parts and swapped the controller board and still no luck. So before I go into our clean room and try and swap the platters from the bad drive into a working drive does anyone have any leads on a data recovery service ???
