PC2001 System Design & MMC-2 Optical Storage Requirement

Hi everyone,

I am not sure how to verify if a CDROM drive is MMC-2 compliant, meaning how can I check if the current drive is accepting MultiMedia Command Set 2's commands ?  (Any avail commercial tools out there ?)

Is there any sticker or logo that will show on those certified drives ?

Btw, who certifies them ?  How would it impact with or without this MMC-2 Command sets support ?  

PC2001 System Design does not give enough details as to MMC-2 .. can anyone provide some insights on this MMC-2 Spec ?

Thanks, appreciate so much for your info sharing :)

Check with the manufacturer of the CDROM drive.  It's up to them to design MMC2 support into the drive and if they have done so, they will advertise the fact.

I suppose it's possible to do some sort of software validation of MMC2 support, it wouldn't surprise me if there was such a utility around somewhere.....

I'm not sure if this will help much, but here goes:

I think the best info is here:
http://www.scsifaq.org/scsifaq.html#_Hlk410810170
Look in the contents for "what is the difference between scsi 1 and scsi 2"
and  "what is the difference between scsi 2 and scsi 3"

Scroll down for SCSI 2:

Straight from the powers that be (for a price):

To answer your question, I think that any drive that is listed as SCSI 2 compliant, fits the bill.

The "other" MMC-2 standard is here:

I don't think this applies to what you want though.

Thx genguy .. I believe MMC doesn't apply only to SCSI devices, right .. IDE devices do have this MMC support as well ... wonder what extra command sets does MMC & MMC-2 provide over one without it ?

Didn't see much vendors advertise MMC-2 in their product, is it widely promoted & supported by exisiting applications ?

Thx for further info... :)
