Hello folks,

We are having a little problem on our university lab. We work with a
Sparkstation 10 with 40 Mhz CPU, 96 MB Ram and Solaris 6.
For any natural reason the machine stoped working and we discovered
it was the disk. We installed an IBM with 2.1 GB and installed Solaris
6. Before the disk crash we ran SunOS 2.5.
We need now get the filed from the crashed disk back because we do
not have backups all the files.
When trying to use format, it says that the disktype is unknown. We
tryed to configure it manually with these informations we got at
internet:

# From: Daniel Curry <dan@filoli.com>
# generated using scsiinfo.
#
disk_type = "CONNER CFP4207S 4.28GB" \
: ctlr = SCSI : fmt_time = 9 \
: atrks = 0 \
: ncyl = 3353 : acyl = 2 : pcyl = 3999 : nhead = 20 : nsect = 125 \
: rpm = 7200 : bpt = 73500

partition = "CONNER CFP4207S 4.28GB" \
: disk = "CONNER CFP4207S 4.28GB" : ctlr = SCSI \
: c = 0, 8382500

Format recognize the disk but says that disk is not formated, mount
also not work for it.
I tryed to use SCSIINFO application and when i try to query the
disk, it recognize it but if i try a more specific query on the disk, i
get this error message:

WARNING:
/iommu@f,e0000000/sbus@f,e0001000/espdma@f,400000/esp@f,800000/sd@3,0

Requested Block: 0 Error Block: 0

I tried a lot of forums and docs.sun.com without success. This is my
last try.

Any help will be appreciated.
Thanks in advance,

Ive tried using this before:
ftp://ftp.berlios.de/pub/sformat/ without success : >
on a truly toasted drive.
If the disk is not repairable your only alternative
I know of is to send it in for recovery. Could be expensive.
Lots of places in the US that do that. You should only
get charged if they succeed.
I guess you appreciate the value of backups now..?

The disk is shagged, that's why it's called "crashed". If the
machine stopped booting because the drive died then what makes you think
you'll be able to get data off the disk? Depending on why the drive
died, i.e. if the bearing froze, then you have a very small chance of
getting the data back. You'll have to take the drive out and bang it
onto something hard (concrete) on the side (not the top or bottom), put
it back in, if it starts/works, BACK IT UP RIGHT THEN, do not turn your
machine off, it probably won't be working for long if this method works
because the bearing will just freeze up again some time soon. If the
electronics or something else are bad, then you might be able to replace
the PC board. You could also pay a fortune to a data recovery company,
it all depends on how much the data is worth to you.

P.S. This method has worked for me on a couple of drives.

Thanks a lot !!!

I really appreciate your help, i´m gonna try both alternatives
and if i get something, i'll give an update to you.
The backup part: I started working on this lab and the disk was
already crashed, i just got the problem ... Usually it is what happens,
you get a new job with old problems. That's the thing that make we
learn.

I've had lots of drives fail in one way or another that still worked well
enough to salvage at least some data from, the banging method is more likely
to completely detroy the drive than to fix it unless it's not spinning up
and the problem has been narrowed to the spindle motor or bearings.

A trick I've found to work reasonably often is to stick the dead drive in
the freezer for a couple hours, then stick it in the computer and try it
out, sometimes it'll run for 10-20 minutes, long enough to backup the
critical stuff.

If I got a job in a lab where a SS10 running Solaris 2.6, with no
backup, had any critical stuff on it, I'd very, very quickly quit.

Giving that it was actually the case, and the data must be recovered,
forget sticking the drive anywhere, banging it, or whatever else. Its a
sure way of making things worse. Get your check book out, and send the
drive to Ibas (www.ibas.com). It will be expensive, but unless you have
already attempted the DIY tricks, they will probably be able to get the
data back for you.

Guys,

I just posted it because it was my last resource. I'm just trying
to check for alternatives that i did not try.
The machine was retired, it will not be used anymore. When i got
this job they just asked me if i could do something. I'm trying. If we
cannot get it back, noooooooo problem.
The most important files are located on a much better server that
i'm taking care now, so, at least the basic administration has been
done.
I'm just looking for ideas and really appreciate all of them.
Thanks again.
