The story is that I the disk got a power surge of 22 Volts for un unknown amount of time. I removed the TVS diode and it spun up again in a new enclosure, but showed as "uninitialised" by mac os x.
I didn't change the sector size, but i'm confused by logical 4096 and physical 512 sized sectors. which one do I choose for these bigger *TB drives?
Your help is much appreciated!
