Title: Mask and max transfer settings for Cybppc.device??
Post by: MikeB on March 07, 2003, 11:42:15 AM
Does anyone know what the best settings are for a quantum atlas drive using pfs3, seems to be conflicting comments on pfs3 docs and amiga page


quote:
Mask should be 0xfffffffc in most configurations. Use a Maxtransfer of 0x00ffffff for SCSI, good IDE drives and controllers, but use 0x0001fe00 for IDE drives that still do not support reading more than 128KB in one access--I had a 28GB drive that did not support it properly. Old IDE drives might even require 0x0000fe00. To be on the safe side, I recommend using 0x0001fe00 for IDE drives, but you can try a larger value and then see if copying large files with a big buffer size (aka copy bigfile hd2: BUF=5000) gives a byte-for-byte identical copy of the file or not.

I believe that I use 0xfffffffc for the mask and 0x00ffffff for MaxTransfer on my system.  No problems.

cool

whats your file system blocksize settings? 1024 or 2048?

you can check in hdtoolbox without changing anything, just make sure you hit cancel.
while your in there can you double check the mast and transfer settings.

Are you running pfs3?

cheers

I use PFS3 with 1024 byte block size.  It doesn't support anything bigger than that.

my old drives i use a block size of 2048, never had any issues. (A4000T IDE Maxtor drive)

Im setting up a quantum atlas 73.4GB scsi drive on my cyberstorm so probably best to use 1024 block size.

i noticed in the pfs3 documentation it says for phase5 boards use 0xffffffff so i assume i need to use this setting for cyberstorm scsi.
