- Problem:
-
- I have just purchased a 3.5" 256M Magneto-optical drive from MacDirect. The
- mechanism is a MOST RMD-5200-S. The mechanism works fine under the MacOS, but
- is not recognized by A/UX, either as Mac partitions or as A/UX partitions.
-
- Symptoms:
-
- An error message is generated in the A/UX start up sequence that reads as
- follows:
-
- Disk write c3d0s30 Error: Illegal request, code = 0x26
- generic disk c3d0s30 Fatal Error: Logical block 0, physical block 0
-
- (The drive is setup as an external drive on SCSI 3.) This error message
- apparently relates to the inability to mount the
- MacPartition on the drive. Also, if I try to create a file system on slice 3
- using newfs it fails, with the following on the command line:
-
- jasper 1 # newfs -v /dev/rdsk/c3d0s3 MODD (My note here: MODD is a
- disktab entry for a Sony mechanism)
- ioctl: No such device or address
- /etc/fs/ufs/mkfs /dev/rdsk/c3d0s3 -1 31 1 8192 1024 16 10 60
- 2048 t
- preposterous size -1
- or
- jasper 2 # newfs -v /dev/rdsk/c3d0s3 other
- ioctl: No such device or address
- /etc/fs/ufs/mkfs /dev/rdsk/c3d0s3 -1 32 16 8192 1024 16 10
- 60 2048 t
- preposterous size -1
-
- The console message from this operation reads (in both cases):
-
- Disk write c3d0s3 Error: Illegal request, code = 0x26
- generic disk c3d0s3 Fatal Error: Logical block 0, physical
- block 0
-
- I am able to successfully change partitions using "Apple HD SC Setup", but that
- program chokes when it tries to establish a UNIX file system. This result,
- however, leads me to believe that the drive has been successfully written to
- under A/UX.
-
- Question:
-
- How do I get this device to work? Is it possible? There seems to be an
- incompatibility in the A/UX system software. Can this be rectified through an
- appropriate entry in fstab? Or is it more complex than that? My guess is that
- A/UX thinks that there are more drive heads in the drive than really exist.
- (Just a guess.)
-
- I have spoken with the A/UX answerline folks, with the MacDirect rep, and
- with a MOST person, none of whom have been able to shed any light on the
- problem. I am set to send the drive back if it won't work, but like how it
- seems to perform and would like to get it on line. Clearly, I am an Unix novice
- and any help will be greatly appreciated.
