Hello Mark!
I'm late, I know, but I just found this thread.
Maybe I missed it, but nobody mentioned block sizes. Newer drives tend
to be Advanced Format, meaning, each sector (physical block) on the
drive is not exactly 512 bytes anymore, but a multiple of that. Most
HDDs use a block size of 4096 bytes i.e. 4k.
The problem is that most older computers, firmwares and operating
systems really require this 512 bytes block size. That is why a lot of
HDDs with Advanced Format use emulation. Instead of reporting the true
block size of 4096, they will report 512, in which case you'd be safe
and could use the drive.
If, on the other hand, you purchased a drive without emulation, it will
report the native block size of 4096. This could have various effects,
including stalling the system completely.
You should read about Advanced Format on Wikipedia:
https://en.wikipedia.org/wiki/Advanced_Format
Does your drive have an "Advanced 4K Format" or an "Advanced 4Kn Format"
logo? The later, with the letter "n" ("4Kn" versus just "4K") indicates
native mode, which will most likely cause problems.
You should get a drive with 512 byte block size emulation, i.e. one with
the "Advanced 4K Format" logo (without "n" for native – i.e. with an
invisible "e" for emulation ;-)).
