I have one Teac model 55 double sided 40 track drive in an enclosure
with power supply, and it is very quiet. In fact, it made my other
disk drive, a Remex, sound like a buzz saw! So, when I decided to
replace my Remex with two double sided 80 track drives, I naturally
chose the 80 track Teac 55 drives. Here, two of them (the look
identical to the 40tk models) are fit into a single enclosure. They
work just fine.
Problem is, they are incredibly noisy! Just about as bad as the
Remex. Not knowing much about disk drive hardware, can anyone explain
to me why practically identical hardware can behave so differently?
Anyone have experience with these Teac drives?
On a related topic, it seems that the Teac drives have a head-load
solenoid. Accessing the drive causes an audible click before any
head motion occurs. I have heard rumors that a poorly written
disk driver (or one not matched to the Teac 55s) could cause media
damage. Should I worry about this? I use these with a TRS-80
Color Computer running OS9.

media damage if any is caused by excessive headload force. This isn't
affected materially by your bios.
While the 48 tpi and 96 tpi drives may have many parts in common, the
stepper motor is certainly different, and so are possibly the "carriage
guide" parts on which the head arm assembly moves. Your new Teac may
need re-engineering.
