PCB: 100664987 REV B
Working fine until I started the computer yesterday
[I'm not sure tag]
Got past "AHCI Drive Init" screen normally
Then computer resetted while loading Windows
[/I'm not sure tag]
Now it's stuck at AHCI Drive Init, if I give it enough time the screen says No Drive Detected
Switching SATA mode from AHCI to IDE results in no image if HDD is plugged in; maybe it would just take forever to POST, but I didn't check that.
I have included a recording of the drive's activity during boot up, until it hangs at the AHCI screen.

After going back home to get stuff
Used Toshiba MK2555GSX (250GB SATA-2 HDD), drive detected as per normal, can enter BIOS and stuff, didn't try booting into Windows because there wasn't any
Changed SATA cable - no difference in symptom
Unscrewed the PCB and cleaned the connectors<br><img src="http://imageshack.us/a/img577/227/motorbeforeafter
No difference in symptom
2 ohm / 0 ohm resistors and TVS diode near power connector tested ok
Now trying a USB-to-SATA adapter, adapter detected in device manager but not drive, suggesting an undetected drive. Then again the adapter isn't young and could use some manual intervention.
Motherboard is GA-MA770-US3, and, although probably this is a given, HDD was working fine until that fateful boot.
At some point in time I suspected thermal damage, then I dismissed it realizing that the HDD died from a cold boot, literally, because I have been out the whole afternoon and the unpowered HDD was chillin' (figuratively) at room temperature.

This drive has the serial number (S1Fxxxxx). If I get another 100664987 REV B PCB from another drive with the same serial number (S1Fxxxxx) and firmware would that increases the chance of recovering the data?

Do the simple stuff first, new cable, and a re-format if that doesn't work, burn yourself a Seatool DOS disk put the PC in IDE mode and boot to that, if it doesn't detect then then it's got a bigger problem, you could also try Gparted and re-set the file table, after that I'd say it's Dead Jim
