GVP Impact A500 boot trouble

Post by eidolon144 » Mon, 04 Jun 2007 08:54:34


I have an Amiga 500 with a GVP Impact A500 hard drive. The drive has
been flakey for the last few years, reporting occasional read/write
errors. Recently it's become much worse, and it's having trouble
booting. The RAM installed in it is still accessible, so I'm assuming
that the actual drive mechanism is going bad.

Question 1: Does anyone know if there's any software available to
check the drive integrity and/or remap bad sectors?

Question 2: Does anyone know if it's possible to throw some kind of
off-the-shelf drive into the case and format it in such a way as to
make the Amiga happy?

Thanks.

David

SCSIQuery & SCSIFormat, off aminet. However, drives should typically
remap bad sectors itself, and only fail if there are no spare sectors
around anymore. Thus, my reasoning is: Yes, this drive is bad, and no
further tricks will bring it back to life.


If you find an off-shelf SCSI drive... Drives larger than 4GB (and yes,
they are) will have trouble with the FFS due to the >32 bit addressing
then required. Otherwise, SCSI should be pretty much backwards compatible.

So long,
Thomas

I'd forget that drive. Ditch it. Back up any important files you have
as soon as possible.

There are workarounds to use the larger drives some of which I
originally downloaded from Aminet, these are the advanced forms of
the FFS and second party file systems like the SFS and PFS. You
don't say which Version of Amiga OS you are using and unless you
are using advanced version you may have trouble. In addition you
might need to use adaptors from the typical 50 pin Amiga SCSI to
the later 68 or 80 pin version so that your adapted connection
might not fit in your drive case so maybe a 2.5 inch IDE with connector
to fit IDE HD to SCSI host *might* work.
Better start looking ASAP for suitable scsi HDs to use and maybe there
are some left.

I have OS 2.04.

If the drive is too large, does that mean that only part of it will be
visible, or that it will be completely unusable?

Are there any criteria I need to worry about other than physical
interface (50 pin versus whatever) and drive size? I can well imagine
it might be tough to find a drive that's no larger than 4 GB.

Thanks.

And which processor, i.e. 68000 or hopefully 68020 or better?

Because you see the definitive upgrade for the file system problem
worked best on AOS 3.9 which requires the faster wider bus processor. It is
why I went to a 68060 in my A2k.


Without the later filesystems it will be unreliable and only appear to
be prepped then fail repeatedly. This is the behavior reported from users
of
drives of the now laughably small 4.3 Gigabyte drives.


Yes it will be hard to find. But start looking and find out what you
can find learn with your resources. Don't forget to check with repair shops
and Amiga dealers, eh. Sometimes these places might have just what you need
having gotten a stock in hand when the bottom fell out of the small scsi HD
market. Advertise for it on the comp.sys,amiga.marketplace, even.

Good luck with this, David. I just spent a bit of time searching my on
hard disk downloaded archives from Aminet and a few other sources but with
the big drives, best bet is apparently 3.9 and the 32 bit bus processor not
the 16/32.

Plain old 68k. I have a stock Amiga 500.


I looked on Aminet and only saw a solution for OS 3.x.


I didn't think there were any Amiga dealers left . . .


Looks like I'm out of luck unless I can find a small drive, then.

What about a flash drive that speaks SCSI? I did find some USB/SCSI
adaptors, but every one I've seen so far adapts in the wrong direction
(SCSI device, USB computer).

ebay


one possibility is a combination of an acard scsi/ide adapter
like the ARS-2000FU and a good quality ide/compactflash adapter
with a sandisk or similar good quality cf card, alternatively
a transchend ide flashdrive module that fits the 40 pin ide
connector of the acard directly.

The GVP HD8+ probably has a hard drive less than 500 megs.
I have several replacement SCSI drives from 40-2 gig, all
formatted,and prepped.
