my power supply unit decided to kick the bucket and take down 3 HDDs with it.
I've replaced the power supply and now I have 3 dead drives and I need to recover data from them.
I'm not sure if I can resolve my issues easily just by snipping off the TVS diodes as I have repeatedly read.
Seagate Barracuda 7200.11 (MDL ST3100034AS - Firm/W: 8D15)
WD Caviar Blue WD500 (MDL-WD5000AAKS)
Hitachi 2.5" 5K500-500 (MDL: HTS545050KTA300)(5400RPM)

ok got the multimeter... set at 200ohms:
for the Seagate ST31000340AS i get a reading of 95.4 on each of the +5V pins and no reading on the +12V
for the WD5000AAKS i get no reading on the +5V nor the +12V
and for the 2.5" Hitachi i get no reading.

my meter shows a "1" which is what I meant by no reading.
so on the WD drive:
D4 - open circuit
D3 - open circuit
with the resistors R64 & R67 I get differnt results depending where I postion the probes (see image).
