I thought that hdparm was meant for IDE drives, not USB ones.

It can be used with both IDE and SATA drives at the man page indicates.

Anyway, I tried the following:

# hdparm -C /dev/sde

Why are you using a parameter for an IDE drive? Are you sure that the
drive is IDE rather than SATA.

Actually, I have no clue. The only thing I know is that it is an
external disk that gets connected to my PC via a USB port. hdparm just
does not seem to be able to do anything much right with it, hence my
reluctance.

hdparm is for internal IDE and SATA drives. An IDE or SATA drive connected via
USB operates through a completely different interface and driver.
