I'm trying to set up a SyQuest 44M cartridge hard drive with A/UX 2.0, and
I need some help with the entry in /etc/disktab.  disktab has fields for
number of sectors/track, tracks/cylinder, and cylinders/disk, but for the
SyQuest I have three sets of these: one for 256-byte sectors, one for 512-byte
sectors, and one for 1024-byte sectors.  Can someone tell me (via e-mail)
which sector size the system is expecting?  And I'm not sure which sector 
size the cartridge is formatted with; can I find out somehow or does it
even matter to A/UX?

If all else fails, I plan to set up three partitions on the drive, make file-
systems on each one using a different set of parameters (256, 512, and 1024
bytes/sector), and see which one appears to do file I/O the best.  

	Thanks,
