Ah! Got it. Thanks.
That works, although it didn't solve the problem for which I needed the
info. Any advice or clever tricks welcome. (See infra.)

I think I failed to mention that my hdd is a CD drive, not a HD. I
don't see anything in hdparm(8) to manipulate the "slow" setting
although maybe it'll help me figure out a hack.
(I'm trying to retrieve data from a CD written under XP. My wife has
moved off of an employer-owned laptop and one CD out of a couple of
dozen somehow got through the checks with some bad blocks. Her
Win98/CD drive won't read it. My PII/Linux/52x drive won't even keep
the drawer shut on it. My P133/Linux/50x drive reads the directory and
some files but truncates some files on a cp or dd with a I/O error. I
was hoping that the drive would succeed in reading the data when
forced to "slow". Didn't. Still bumbling around trying to find a
hack to recover as much as possible. Call it a learning
