Well, my new machine came with a Microscience hard disk. Made in Taiwan.
3.5", 115Mb, not as compact as a similar drive I have seen on a Compaq.
960 cyl, 7 heads, 35 sect/track, IDE.  What I definitely don't like
are the vibrations. I would expect the drive to not vibrate at all.
Vseek and Coretest show an Access time of 18-20 ms. Data transfert about
960 Kb/s. I suspect a cache built into the controller as the DOS copy
is much slower. It makes strange noises on power-up, apart the "shtong"
on head deparking. The technology is probably voice-coil, and the eight
track reserved for head positionning. There were no docs provided by
the vendor, except for the external "controller".
