#HD Max Transfer Settings
I need some help here with an IDE drive in an A4000. The drive is an IBM (OEM)
170 Meg model H3171-A2. It has 984 Cylinders, 10 Heads, and 34 Blocks/Track.
I installed the drive with HDToolBox (which correctly read the config from the
drive), formatted with FFS and all seemed fine. I installed WB3.0 plus lots of
apps and most things worked OK.
The PROBLEM emerged when I tried copying over some large programs & files
(>200K). The data is fine if the file is written with multiple small writes,
but not with one big continuous write. (eg. image saved from paint program –
fine : image file copied from RAM: to HD: – not OK)
This leads me to suspect that the Max Transfer rate may need changing
(currently $ffffff). The question is:- which way should it be changed (up or
down) and what sort of value would anyone suggest? Or what else may be to
blame?
This is not a well documented area, so any help would be much appreciated.
