: you must write your own program sending raw scsi commands to read the
: contents. NetBSD can't handle sector sized != 512 now and for sure won't
: ever handle non power-of-two sizes.
520 bytes per sector looks weird, I didn't know such a disk existed, would have
thought sector size would be a power of 2. Are you sure you read the datasheet
correctly?
[snip]
I also have two SCSI drives that have 520 byte sectors. They are IBM
drives, and from the little bit of information I found, they were probably
pulled from an AS400 system. No proof for this, but it is the nearest
thing I have found, other then firmware bugs, that would explain this sort
of thing.
I think I tried to low level format them on a Sun Sparc, using the NetBSD
format command, but I don't think that it worked.
