Can I confirm that an HD should spin up if powered, but the SCSI bus not
plugged in?

I have a situation here whereby the IDC connector at the back of a scsi
caddy (rack) housing can ease out due to it being an interference fit
with the nylon surround of the adjacent power connector. This has been
known to cause a drive not to answer.

I have shaved a little off the nylon to help but it cannot be completely
cured. It just takes longer for a problem to show up, that's if I have
not carried out a routine service in time.

Not necessarily.

Some SCSI drives have a jumper which allows the drive to be set to
remain dormant until it receives a request from the controller.

Right. I've not stripped the machine down yet as it's in the most awkward
place possible. However, when working it seemed to start spinning up when
the machine was initially powered up - before boot started running.
I've got the Castle Storm SCSI card and didn't notice that option in the
software - which would have been nice given that I don't use the SCSI HD
all the time.

Is the drive internal or external?

Castle Storm can stop seeing anything externaly due to a problem with age of
the tracks to the external connector:-(

Usually the host electronics will issue a start unit request at early boot
time to connected devices which'll cause them to spin up, then they'll
issue an inquiry command to see what's actually connected - I suspect
this is what was happening even if the drive didn't start automatically
when given power.

I've never known a drive that can't be configured to start as soon as
power is applied; some drives don't support disabling of autostart
though.

Most modernish SCSI drives support spin-down - whether anyone's written a
utility to exploit it in the Acorn world is another matter. Plus there's
the issue of whether the OS will get upset; if it's holding any data on
the drive in any kind of temporary files and finds the disk is spun down
then it'll appear to the OS that the drive's dead.

Automatically spinning down the disk is another matter as it'd need to be
integrated at a low level within the OS.


I'd be *very* wary of putting any lubrication on drive spindle bearings if
that's what someone was advocating - far as I know the bearings are
designed to be run dry and so adding anything could really screw things up.

I'd be more inclined to suspect a cabling fault at this stage.

The external devices appear to work ok - scanner and CDW.

Do you have any other internal devices?

Have you tried a new internal cable?

Have you checked termination?
I have known systems that worked for a long term with incorrect termination
and then stop until correctly terminated.  
Though incorrect termination does not normaly stop *devices from working!

Crikey. One to remember.

I've finally got round to removing it - it was in the bottom 'slot' of the
main case.

Tried powering it up from an external source, and it doesn't spin up, but
is drawing about 2.5 amps at 12 volts, so something's not right. ;-)

Sounds like it's probably stiction (where the drive heads stick to the
platters) or spindle bearings. With power applied, give the drive a sharp
twist in your hand, it'll usually get it running in everything but the
worst of cases.

If that does prove to be the case, copy everything valuable off the drive
to a replacement and bin the dodgy drive, as once it's happened it'll only
happen again.

As a last resort you can always pull the cover on the drive and get things
moving by hand (just don't touch the data surfaces on the drive!) in order
to do a copy.

Thanks - I'll give that a try. I thought there wasn't anything I needed on
it, but now find out there is. Not a disaster if I can't recover them,
though.

Eggs in the one basket?  Surely not!  Everything here is in at least
three completely independent "baskets", and most of my files are in
five or six (or more).

The sticking on the bearings was the reason for my suggestion to turn
upside down and give it a sharp rap.

You could find that if it starts up once then it may keep going for some
while yet.

Yes, I did try that Lionel. But nothing. Next thing is to try the 
twist. ;-)

I'd not rely on it though.

A sharp rap should be the LAST RESORT, Jules suggestion of a sharp twist has
worked for me on a number of occasions and is much less severe, and very
unlikely to damage the drive which a rap could!

p.s. if it is a last resort try the rap with drive powered down, and only if
the only other option is the bin should you hit it with power applied, and
NEVER is you can here it spinning of course.

A sharp twist along the same axis as the platter is best, powered or
not.

Depends how hard you rap, just enough to unstick from the surface tension
of the lubricant will do and being upside down may let the platter
assembly drop slightly on the bearings but not far enough to damage heads
or platter. After all most drives are built to withstand some shock
loading these days.

I would consider lifting the lid far more detrimental potentially.

No, the *last* resort is putting the thing in the freezer for half-an-hour
or so.  However bad it was, you'll almost always be able to get it working
perfectly for long enough to get the data off.  It'll just never work again
after you spin it down....  (Warning for anyone who hadn't guessed: this
will invalidate any guarantee the drive may have! :-)

That was a trick I came up with some while back for rescuing data from
failing Fujitsu drives. It only worked in instances where the failure was a
temperature dependant problem arising from gradual controller chip failure.

Interesting to see the tip being promoted again - I thought all those
dead/dying Fuji jobs were buried now. Or are you saying it worked on
another make/model of drive with a similar problem?

Hackcherrly it worked several times over and the working period could
(can?) be extended by keeping the drive cool with cold air blown over the
drive.

Our users tend to think of the data as valuable and the drive as a
thingummie in the box that holds the valuable data - just replace the
thingummie and the data is magically OK. (Sadly not true)

I've found a pan of ice cold water resting on top of the drive and
lots of airflow underneath from an hairdryer on the cold setting is
better; no risk of moisture in the drive electronics then causing
things to go bang!

If the OP tries taking the lid off the drive, do it in as
dust-free an environment as possible (and rest the lid back on top
of the drive if manual intervention gets it spinning). I've heard
of drives lasting a few weeks like that constantly running before
the heads crashed, but you should certainly get enough life out of
it to copy the data off.

cheers

Mine died for no apparent reason a few months ago, and no SCSI utils would deal with it (including Seagate's own). I'd put it on a Cumana SCSI2 card, set 2.5GB for RISCOS (5x512MB, RO3.11), and was trying to use !Partition (or is is !PartMgr ?) to set up Linux partitions. It suddenly started making an alarm-like noise when trying to access around the 2.1GB mark (i.e. start of the fifth SCSIFS partition) which held a large DOSFS file and !PC. Neither the Cumana SCSIMgr nor "Seatools" could format the thing (even when at Seagate's suggestion I set the format size to well below the problem area), which is still sitting on a shelf.

Unable to reformat hard disc on RPC #2
Hi, I have a RPC running RO 4.39 Adjust which is soon to go to a new home, and I'd like to reformat the HD before it goes to its new owner. Only problem is, I can't! I've copied !HForm to floppy and booted off it (shift-boot). Then run it as *!hform. Although it runs, it fails to format the disc. I've tried v2.56 and v2.58 but both fail: In 2.56, I take the default answers, choose F for format, S for short soak, Y for bootable and Y for long files. It tells me there's formatting in progress and a number increments to 19846 (= cylinders) but there's no disc activity. It then says "verifying ..." and, again, nothing. It just hangs. In 2.58 I again take the default and choose similar to 2.56 (Format, Short soak, Bootable). In this case I'm reported with an error and the format fails: A disc error has occurred when attempting to format this disc (error code 2) process aborting ... 4 0 0 0 0 0 81 And that's it! Otherwise, the disc seems fine, in as much as I can boot off it and run applications, etc. Any advice or suggestions (short of putting a hammer through it) are welcomed.

Freebie: Original Acorn 210Mb Hard Disc
In the course of helping a disabled friend to clear out a lot of old Acorn kit I have acquired one of the original 210Mb hard discs that were fitted to some Risc PCs. It is now formatted F+ (long file names) and contains the rudiments of a RISC OS 4.02 installation. I could re-format it to F (as original) which would leave it empty.

SCSI formatted USB hard disc limitations?
I have been successfully using a DOS-formatted 2GB HDD connected via a USB external caddy to back up my Iyonix for some time. Following comments in the recent "USB Hard Discs..." thread, I thought it might be a good idea to format a larger disc using !SCSIForm and use that instead. The disc formatted fine and files copied readily. However, what seems to happen is that, with some folders, the system locks up before the entire contents are copied. For example, lockup occurs with the !Boot folder when approx. 101 of the 103MB have been copied. Subsequent attempts to add even one file to the folder are unsuccessful unless some files are deleted from it first. Similar problems occur with several other folders that are much smaller in size than !Boot. This appears to indicate that there is a "number of files per folder" limit with SCSIFS, although comparisons of file numbers in the offending folders doesn't seem to show any pattern. Can anyone shed any light on this? Have I missed something really obvious? Googling has been no help.

SCSI formatted USB hard disc problem solved!
A couple of weeks ago I posted to this group about a problem I was having backing up files on my Iyonix to an external USB hard drive formatted with !SCSIForm. Although some files copied to the drive OK, eventually the system would lock up and refuse to add any more files to the current folder. I am pleased to report that after upgrading the Iyo to USB2 the problem has been solved.

Hard disc upgrade, ramdisk problems and notes #2
Having just succesfully upgraded my hard disc, i thought i would put down my observations, hopefully they could smooth the way for future passers-by. System : Mandrake 9.1 1. Follow the hard disc upgrade HOWTO. If, when trying to boot from the new disk, you get the error message 'Unable to find valid ram disk...unable to mount root partition...' the following notes may help: 1a. If you change the root filesystem type, you will need to use mkinitrd 1b. At first the hard disc device name (eg hd5) of my root partition was different on my new disk. Eventually, i set up both discs so they were almost identical. This may not be necessary. 1c. The magic of having /disk1/boot become /boot without any sort of copy or rename happens because you don't (or hardly) change the file /etc/fstab 1d. Because i originally had 2 discs connected, at first i tried simply swapping them over. Eventually i got the new disc working without the old one connected. This may not be necessary. 1e. I still got the 'unable to mount root partition' error, so i booted from the installation cd, chose 'mount disk under /mnt' and then edited the file '/mnt/disk6/etc/lilo.conf' (disk6 would become the root partition) so it corresponded with the file on page 12 of the HOWTO (eg change instances of '/disk1' to '/boot'). Then rebooted from CD and chose 'rebuild Lilo', finally reboot from disk - success at last! Note - th...
