Hi.
My computer was working over night.
When i woke up the next day my computer was shut down and refused to turn on.
When i disconnect the Seagate Ironwolf the computer starts fine.
Attaching the disc to another computer yields the same result.
Computer doesn't want to turn on...
So i suppose there's a short circuit in the harddisk somewhere?
The hard disk is fairly new (manucfactured Oct 2018), bought 3 months ago.
So i can replace it under warranty that's not the problem...
The problem is i need to rescue the data that's on the disk.
Searching the internet it seems some "TVS-diode" is a common error?
I removed the PCB from the disk, but before i make things worse i'd rather seek for advice.

1) Attached is a photo of the PCB and the parts i identified as TVS-Diodes.
The reading on the chips says "K6U4..."
Is my assumption correct?
2) Attaching my cheap Multimeter and doing a diode test i get the following readings.
Diode 1:
Direction 1: 195 (i believe it's mV)
Direction 2: 1
Diode 2:
Direction 1: 195
Direction 2: 826
So they act differently?
And Diode 2 doesn't "block" in Direction 2?
So i can assume it's faulty?
Thank you for your time!
appreciate any help regarding this
