Hello Larry,

Who knows what linux I booted on that thing but it didn't care and some of the drives I used were 6607s (I used to have a ton of 'em!)

I'm not 100% but 95% sure that even RedHat didn't "enhance" the block layer of their "special" kernel to support 520/522 Bytes per sector.

Perhaps a driver bit?

modinfo -p sd_mod yields nothing, so: No.

I used dual port SCSI cards (non-raid) from Adaptec.
68 pin style type with any needed adapters depending on the drives I was connecting.

Doesn't make a difference. HBAs, and their drivers are just a way to enable SCSI devices being used at all, aka, hardware specific driver. Cable adapters work even a layer below that. :-)

I'm swampped getting ready for 'silly season' (the season in which we speak a lot!) so I might not get the thing out and running for a while.

This is a pity. I really want to know about this.

Silly season will be over somewhen, I guess?

:wq! PoC
