[comp.unix.aux] SyQuest 40MB removable won't mount under unix

shani@TAURUS.BITNET (02/27/91)

Hi,

Could anyone help me with mounting a SyQuest 40MB removable disk under A/UX ?

The disk is formatted for Mac/OS (with the MacOS standard formatter) and
when A/UX boots, it says:

generic disk c1d0s30 Retry limit: Logical block 0, physical block 0
Disk write c1d0s30 Error: More data than SCSI device requested

and doesn't mount the disk.

? HELP ???

Thanks in advance,

O.S.

This sounds like another case of the standard problem with SyQuests and A/UX--
You need a copy of Tony Cooper's scsi-fix-error-page utility which is available
in the info-mac archives.  If you can't get it yourself (its under:
   info-mac/util/scsi-fix-error-page.hqx  )
let me know and I'll mail you a copy.

What Rick omits to mention is that there is a program which claims to do
just that on Apple's own support system, aux.support.apple.com.  It's in
a uuencoded compressed tar file by the name of
/usr/spool/ftp/aux.patches/unsupported/fix_error.uu.  Snarf it, unencode
and unarchive it, and you'll get a Mac application called Fix Error Page
and a TeachText README file.  For those with ftp, the internet address
of the system is 130.43.6.2; for those without, call +1 408 559 3066 and
login as aux.  (Twice.  You'll see what I mean.)  For anybody, the
system is  S L O W , but a whole lot better than nothing.

By the way, I haven't tried the thing.  I thought it might be a fix for
uux...
