MaxTransfer for IDE-CF

[lurkist]

Got my Compact Flash card up and booting in a spare A1200 after a mishap with (literally) crossed wires!  Works a charm, but I only have a 32MB card for now, waiting for a cheap large one on eBay.

Question -

Since CF cards generally seem to claim 8MB per second, what Max transfer settings are people using?

Cheers

64k - doesn't sound like something I'd type into that field, eg. default is

0xffffff

but is apparently best suited to SCSI drives.

I've seen an example for IDE drives that says

0x1fe00 or
0xfe00

I also found this on a FAQ -

"For unknown drives, the maximum "safe" value is 0x0001FE00. Other (older) drives may require 0x0000FFFF or even 0x0000FE00. The sure test is to copy files larger than the MaxTransfer value to and from the drive, checking for corruption afterwards. Pictures work well for this, as corruption is easy to detect."

but what does it all mean?!?

I'm assuming they're HEX values which I don't understand.  Is there a calc util to decipher these strange figures?

Cheers

OK, according to a HEX calc util I found on Aminet, the figures above mean-

0xffffff = 16777215
0x1fe00  = 130560
0xfe00   = 65024

There seems to be no logic behind them, particularly the default which is wayyy bigger than the reccomendations.

64k = 0xfa00  Should I type this in?
