I was working on my Dell nb this morning when it locked up hard. I did a hard reboot and got the drive failed error right afer the inital bios check screen. I call the mfgr's tech support (seagate), and they had me down load their seatool for dos onto a CD and boot off of that to check the drive. I did that but the program froze during the "searching for drives" portion of the boot up. It never got to the actual test. The drive makes some humming and clicking noises for a while why it tries to boot, but then it quits. The tech said that the drive was dead. The though they might be able to recover data, but that prices for that start at about $700 and run up to $3k. He said that since its not even seeing the drive, the DIY recovery options are not an option. The data on there is not worth that kind of expensdature, but there is some stuff there that would be nice to have. Right now the drive is in the freezer. Figured I might as well try that trick. Is there any way to determine if its a mechanical failure or an electronics failure? I've read that you can sometimes switch the circuit boards in an identical drive and get the thing working again. It would be worth spendign 80 bucks on another drive if that was possible and likely to work. Does that trick even apply to the 2.5 inch notebook drives?
