Hi, Can anybody help me out with this question ? I currently have a Adaptec 4000 ST506 to SCSI controller and I'm trying to hook it up to a Maxtor 1085 ST506 hard drive. The controller in my Amiga 2000 is the 2090a. I would like to know if this should work and if anybody knows of any information about the Adaptec that I need to change to get my drive working as a SCSI drive. || BY THE **+++++ Judd Pape +++++** BY THE || .

Judd, Yes, the Adaptec will work. There is one major caveat though, in that the Adaptec requires a MODE SELECT command with particular data before it will accept a low level format, so you will have to low-level format it on another controller. -larry

Or use a host adapter and formatting software from someone who has taken the idiosyncrasies of the Adaptec into account. 😉 Craig

Craig, I just purchased an Advantage 2000, and was trying to use it with an OMTI 3520, which was then connected to a Seagate ST225. When I ran the software, it recognized the OMTI device correctly. I then selected ST225 as the drive type, and clicked FORMAT. It warned me about losing all data, then displayed FORMATTING… for a second. The drive light went on, then shut off, and the message FORMAT ERROR–SENSE CODE $19 showed up. What's this mean? The OMTI has the jumper selected for device #1, and the drive has the select jumper in the first position. I have a Quantum 40s on the way, so it's not imperitive that the ST225 works, but I'd like to know what the error code means, perhaps telling me where the error is. Andrew —Andrew

Andrew, Mode Sense 19 (hex) is 'defect list error' meaning that something was wrong with the defect list kept on the drive (probably not there yet since this was apparently your first use of the Omti-ST225 combo). I can't help you on why you got this error, Craig should be able to assist you on that though. Don

Don, Thanks for the info…is there a list of these sense error codes? Perhaps in the tech docs for the Amiga? —Andrew

Andrew, No, the sense codes are in a book sitting by my side on the SCSI definition. This particular book is from AT&T, but the sense codes are standardized for the most part. Don

$19 for the Omti is a defect list read error. THis is a very rare thing. It only happens when the drive has been previously formatted and a read error occurs. Call the office for tech support and the provided number. Jerry may be able to figure out how to reset this. Craig
