ImageDisk - need info on Adaptec 1542CF

[Dave Dunfield]

One of the guys trying my ImageDisk program is using an
Adaptec 1542CF controller - he can read disks fine, however
when he tries to write them, it gets an error during every
write sector command.

The status registers reported ar:

SR0: 41
SR1: 04
SR2: 00

According to the NEC 765 datasheets:

41 means "Abnormal Termination of Command"
         "Execution of command was started, but not successfully finished"
         No other error indicators

04 means: "B3: Not used, this bit always low (0)", No other error indicators

00 means: No error indicators

Looks like the controller in the Adaptec is using B3 as an error indicator,
however I do not have any information on what this means ... Does anyone have
technical information on the Adaptec controller and can tell me what this
bit means?

Regards,
Dave
