Hi all,
some days ago i ask this:
i have to read data from old MODs. There is an old MOD SCSI drive from
Sony available. Is it possible to install a MOD drive like a SCSI disk?
I have only to read the data and i can always boot the host for the next
MOD. Are format.dat entrys availably?
Thanx for all answers:

What model is the old drive ? If it's an RMO-S550 like mine then you can use the following from my /etc/format.dat.
# The disk actually has 18751 tracks. Tracks 1 & 18750 are reserved, tracks 0 # & 18749 are Control Data Areas, tracks 2 & 3 are the Defect Table Area. # Formatting sets 2048 sectors aside for sparing, and the controller takes # another 1024, so we lose 3072, or 100 tracks, leaving 18645 user accessible # tracks. There are actually 18645.9 tracks (578023 blocks), but I don't # want to deal with partial tracks. And to cap it off, the format program # likes to take the last 2 tracks for backup labels, so we actually end up # with 18643 tracks (i.e. 18643*31*512 = 295.9Mbytes) per side to use. disk_type = "Sony_MO" \ : ctlr = SCSI \ : ncyl = 18643 : acyl = 2 : pcyl = 18645 : nhead = 1 : nsect = 31 \ : rpm = 2400 : bps = 512 : bpt = 23126 # # This is the list of partition tables for the Sony SMO-C501 controller. # partition = "Sony MO Whole Disk" \ : disk = "Sony_MO" : ctlr = SCSI \ : 0 = 0, 577933 : 2 = 0, 577933

From: Phil Antoine <antoine@RadOnc.Duke.EDU> I have the Sony S-501 external MOD unit. Its media is 300Mb per side at 512 bytes/block. I think this is the *old* unit you are talking about. It vintage 1992 and still serves us well. Here are the entries I use with it.
disk_type = "Sony Optical Media 1DA1S" \ : ctlr = SCSI \ : ncyl = 1160 : acyl = 2 : pcyl = 1162 : nhead = 16 : nsect = 31 \ : rpm = 2400 : bpt = 15872
partition = "Sony Optical Media 1DA1S" \ : disk = "Sony Optical Media 1DA1S" : ctlr = SCSI \

However I use a commercial software to run them, so the formatting process etc. is transparent, however I have seen they are recognised by Solaris 2.4 'format' program as <drive type unknown>

Well, i can't say now, what is correct, because i have a second problem and no free MOD: The MODs are written by a Macintosh system. Can i read this from a Sun (on the MODs are tiff pictures)?
I only connect the drive to a Sun and i have some SCSI trouble on the bus. Well, i think the user must go to someone with a Macintosh ....
But thank you for all answers!
