Good morning all,
I have a problem with a drive in a SGI Indigo2 that I haven't been able to
fix and don't know what else I can do. It goes a bit like this.
When powered on the machine goes through the usual preliminary checks without
problems. When it starts to load the OS it goes into an infinite loop
reporting a media I/O CRC error. If I run the maintenance mode diagnostics
before allowing it to boot, there are no problems reported with any of the
hardware. (The diagnostics don't look at file systems etc. on disc.)
I have put the drive into another machine having changed its SCSI ID, and
rebooted. The new machine OS (also Irix) recognises the disc and can read
the partition table. It can also identify the file system (EFS in this case)
and knows how much available space exists.
When I try to run fsck on the partition, it starts the first pass checking
blocks but doesn't get very far before encountering a media I/O error. After
retrying the particular block a number of times, fsck stops to ask if it
should continue or stop. If asked to continue - the same problem.
If I try to mount the partition, get a similar infinite loop as when trying
At this point I am thinking that maybe there is an area of the disc surface
that has become defective. My main problem is that I don't know enough about
Irix or SGI systems to know how to proceed from here, or, if there are any
utilities etc. that I might be able to use to salvage the file system and/or
any data off the disc.
Insert plaintive cry for help here. :-)
