Amiga HD question

[Oldsmobile_Mike]

Can anybody recommend a program that will completely wipe out 1 partition on a hard drive?  I found WipeDisk on Aminet, but this looks like it does the entire drive, not just a single LUN.

Thanks,
Mike

Try Windows. It is good at such things.

I've already thought of this, if I can't find anything else...

What's wrong with doing a full format?  That should completely wipe it.  Or you could delete the contents and run ReOrg in "clear empty sectors" mode.  If you're using Amiga filesystems I very much doubt anybody is going to be able to get any data off it anyway (unless they know it's an Amiga drive).

Hi Chris,

That's a very good question, with an unfortunately stupid and complicated answer.  Both ReOrg and Format require the partition to be mounted in order to work on it.  However because it is a DC-FFS partition that's become invalidated, as soon as I mount it my 1200 crashes (not enough memory to validate, etc.)   Do you remember our previous thread from a couple weeks ago?  Yep, this is the same problem still.  Between work & school I don't have much time to play with my Miggy.

So anyhow, if I disable the partition from early startup control I can boot just fine on my 3.1 backup partition, but the only program that can see the evil nasty 3.9 partition when it's unmounted is HDToolBox, which sees it, and claims to be doing things to it, but which isn't. :-(  So I need to first wipe this partition out, then reformat it, then reinstall 3.9, unless DiskSalv can manage to do it's magic (it's on about it's 20th try this very minute - I've been able to catch it in the about 2 seconds time frame there is before the crash).

Many thanks,
Mike

Hi! Not wanting to sound anal, but I must mention that LUNs and partitions are two different things.

Yes, of course you're right, Jope.   :-)   My hard drive setup is so messed up it confuses even me sometimes!  :-o

Currently it's like this (please note that "SCSI" is actually A1200 IDE with 4xEIDE interface)

SCSI Address 0, LUN 0:  split into 2 Partitions:  WB3.1 & Storage, HD0: & HD1:
SCSI Address 1, LUN 0:   WB3.9, HD0.1:
SCSI Address 1, LUN 1:  Work, HD1.1:
SCSI Address 1, LUN 2:  Games, HD2:
SCSI Address 1, LUN 3:  Data, HD3:
SCSI Address 1, LUN 4:  Storage, HD4:

(Oh, and there's a CD1: & CD2: floating around somewhere, too :-D )

Blah blah blah, so anyhow, when I ment one LUN, I ment SCSI Address 1, LUN 0, which for me is partition HD0.1, my invalidated Workbench3.9 partition.

@all -

Thanks for all the suggestions, will have to give it one last go before sticking the drive in my PC.  Especially interesting is the suggestion for changing the size in HDToolBox.  What I'd been doing before was going to Partition Drive, deleting the partition, creating a new identical one (FFS Intl., not DC-FFS), saving & rebooting.  This doesn't seem to work, even though it claims "all information will be lost" because I've noticed on subsequent passes of DiskSalv that in fact the information is all still there.  I don't know if this is a testimony to DiskSalv's ability to still read the disk, or if the disk is just not being repartitioned.  I'd think the latter, perhaps only because in it's invalid state it can't be repartitioned?   :-?  Doesn't seem to make sense.  Regardless, DiskSalv still usually chokes sometime around the first couple blocks on the "HD0.1 Program Failed" error, even with the dos lock.  Ah well, back at it, and thanks again!! :-D  :-D  :-D

P.S. - Semi-related topic, does anybody know what sort of disk format the Pegasos uses?  Is it SFS?  I already know about needing the CatWeasel to do floppy disks, but can Pegasos read Amiga formatted hard drives?

P.P.S.  I swear to God I will never again use a DC-FFS formatted partition, not even on a Professional Amiga 2000HD!!  :-D  :-D

Best,
Mike
