[comp.sys.next] Can't insert optical disk

smb3u@mendel.acc.Virginia.EDU (Steven M. Boker) (12/30/90)

A tale of woe from a sadder but wiser 2.0 user.  I was initializing some
Optical disks yesterday.  Insert the previously used OD in the drive and
then take the _disk_ menu item from the workspace menu.  Then click on
_initialize_ submenu item and click OK.  Right?  Yes, unless you are logged
in as root.  I had initialized several OD's in a row and was not paying close
attention. 

I now know that you mustn't let your mind wander.  I was logged in as root
and doing other administrivial tasks while the disks were erased.  I now
know that the _disk_initialize_ menu item will initialize the current target.
This is a very bad idea if the current target is your boot SCSI drive.  I
realized I had been a very bad boy when the workspace went away and the drive
went into swizzle stick land.  I managed to powerdown via the keyboard and
booted to OD.  I mounted what was left of the SCSI partition and recovered
the few essentials that weren't on my most recent backup.  I then tried
to reboot the 2.0 OD and found out that my 2.0 OD had unrecoverable ECC
errors.  Hoo boy.  Out of the frying pan...

I managed to build a new 2.0 OD from a friends machine last night and then
this morning I rebuilt the SCSI.  The SCSI panic>ed when I rebooted to the
hard drive and so I said, "self, let's rebood to the OD".  But now the Optical
Drive won't accept a disk.  I know I'm in some twilight landing zone on
cylinder -1 someplace.  That must be it.  I rebooted to the SCSI and now
it will boot.  But I still can't insert an optical.

Does anyone know why an optical drive would not accept a disk?
