Amiga 1000 SCSI drive error just now...

[blakespot]

I have an A1000 booting KS 1.3 and WB 1.3 off floppy, handing boot sequence off to an attached SCSI HD. It's been working fine for a good while.

I was just downloading some data via serial link when the system Guru'ed and rebooted. Now when it comes up I get this:

Retry does not help. What's happened here? Thanks.

If I hit Cancel, then things boot on to the Workbench, no more errors -- apparently ok...

Is the error coming from the floppy disk, or after it's handed off the boot sequence to the HD?  In either case I'd be concerned that your drive may be starting to fail, or might've been in the state of writing data to the drive during the Guru, so you've got some corrupt data on there.  Not sure what disk checking applications work under 1.3... Um, DiskDoctor?  :-/

The error is definitely after the HD has taken over. Not a floppy issue.

I've had Amigas with HDs for years, never had a drive go south due to a guru during a write. Is that a somewhat common thing? The drive in question is a pretty old 40MB Quantum SCSI disk, but a straight up semi failure of the physical disk coincidental with a guru during a write seems...coincidental. Dunno.

Ok, I grabbed DiskSalv 1.42 - thanks.

It wants a source and a destination... So, I need to have a 2nd HD of >= size mounted to use DiskSalv, I guess? Is that right?

BTW any attempt to write on the disk results in an AmigaDOS message : Disk is not validated.

Is there a program out there that scans a drive for physical errors? To determine if a reformat of this disk would be a good route?

Also - if I need to replace the disk, what are the physical size constraints on AmigaDOS 1.3? I have a 40MB disk in there now and it's nowhere near full, just FYI.

Thanks.

It seems crazy.

So -- a guru during a write can cause a disk to be come unvalidated. And in order to fix it (well, with DiskSalv), you need a 2nd hard drive or partition of >= size on-hand? I ran 1.3 with a HD on my old A2000 back in the '90s for a year and a half and that never happened - just had one HD, partition -- luck I guess?

I know more recent AmigaDOS versions auto-revaldiate on boot. But, in order to use and enjoy this Amiga 1000 with 1.3 and a HD, I necessarily need to have a 2nd volume on hand to handle these incidents? Is that the reality?

Re: The QuarterBack tip --- does that also need a 2nd volume on-hand? (Which I do not have)

Thanks.

Ok...

So I am going to add a 2nd HD to my Amiga 1000 so I can keep enjoying it for some time.

It's been a while since I was all over building MountLists for KS/WB 1.3. What I have in there now is a Quantum 40 MB SCSI drive. It's hard to find drives that small on eBay, vs ones a few hundred MBs in size. What is a good top limit for a drive I should go for? Are there any brands to avoid in the name of compatibility? I know you don't want the drive to be too recent. My controller is a Microbotics Starboard II side-module (w/ 2MB FAST + clock).

If I want to connect one of these SCSI drives to my Amiga 2000's and its Blizzard A2060 SCSI controller, do I need to reproduce a mountlist (OS 3.1 there), or can the OS figure it out?

Any advice appreciated - I want to grab a drive soon. Thanks. I found a nice enclosure already.
