[Hidden-tech] external 4TB drive not mounting

[DM Cook]

If you hear it spinning but not mounting, it could be a bad component of
the drive case, such as the power supply or the FireWire chip. FireWire
drives nowadays are fairly old, so this isn't that uncommon, and often it
doesn't affect the underlying drive. You can resolve this by getting a
different 3.5" case (they tend to run $20-50, generally higher for
FireWire), disassembling your external drive case, and putting the drive in
the new case--  but you'll need to make sure it's the right style for your
drive (SATA II/SATA III, etc)

 Hopefully the problem isn't the drive itself: if it is, you'll probably
need a professional. A symptom of this would be that you hear it click
rhythmically or if it suddenly makes loud individual "honks".

If the problem is corruption or data errors on the drive, a fantastic piece
of software called DiskWarrior can often help, but this will do nothing if
the problem is physical in nature. DiskWarrior has saved more drives than I
can count: it's definitely one of the best and most reliable utilities I
own.

A data recovery expert has access to all of these tools and would most
likely be able to resolve the issue, whatever it is, for around $200.
