I am not convinced of that. I think 'G' implies 360RM. The drive in
question is a 'GFR', thus having the capabilites of both the 'G' and the
'F', in other words both 360 and 300 rpm.
I am certain of the GFR, I have maybe 8 spares and 5 in use to confirm it The
_drive_ is HD, I am not sure what the controller can do, though. The
suffix letters of Teac drive numbers seem to indicate the specs as
follows :
A : 40 cylinder single-sided
B : 40 cyclinder double sided
C : 77 cylinder single sided (??? I have never seen this)
D : 77 cylinder double sided (??? or this)
E : 80 cylinder single sided
F : 80 cylinder double sided
300 rpm only
G : 80 cylinder double sided, 360RPM, high density
(1.2M for PCs)
Does both 300 and 360. (can replace the E and F with correct jumpers).
