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
I am also certain about the GFR. I agree with you. The GFR is a dual
speed drive, 360 rpm and 300rpm.
What I am saying is that the letter 'G' as a suffix indicates a 360rpm
drive. The letter 'F' indicates a 300 rpm drive (both being 80 cylinder
double-sided). So both G and F mean a dual speed drive.
No Tony, the 55F in single speed only. Now if you mean 55GF is dual speed
Agreed. F means 300 rpm 80 cylinder 2 heads.
you might be right by coincidence. However the second
letter and third are
for options to the basic drive such as door latch or media ready indicator.
The third letter, sure. But I thought single speed/density drives had
just 2 letters (type and options), dual speed/dual density drives had 3.
I've certainly seen HFR (or some other 3 letter combination starting with
'HD') for 3.5" drives capable of 720K and 1.44M.
