Volume DH0 not valildated

[murple]

Sorry to dig up an old thread, but I figured itd be good to put it in the same place for anyone else with this issue who finds it in a search as I did.

I was installing the game Aqua from AmiNet on my A2000. Halfway through the first disk un-lha-ing, I got a guru meditation. After reboot (even after power cycles) I'm getting "disk not validated" on DH0: and I cant get it cleared up.

I tried running DiskSalv in Validate mode, and when it rebooted I got checkusm errors on a disk block, or the same validation errors in CLI. So, no change.

I'm trying it now in Repair mode.

As far as I know the drive is in good shape, so... I hope this works.

@#&*@$&@! DiskSalv guru'd.

I'll have to run that when I'm home. The system was an ebay purchase, and is an Amiga 2500 with a GVP G-Force 030 Combo accelerator/SCSI card. It's running WB 3.1 with 3.1 ROMs. The hard drive is a 4GB split into 2 partitions and connected to the G-Force. There is a CDROM connected to the same SCSI.

I'd hate to wipe it since there's a ton of good software on it. I dont have an easy way to back it up either.

The only CD/DVD burners I have are IDE, and I dont have an IDE interface in my A2000. Probably the best I could do would be to dismantle the Amiga and take the drive out, find a SCSI card for my PC, and copy the files there. I could put a second hard drive in the Amiga and copy files there, but with all the disk validation/checksum errors I'm getting, I'm not sure that would work so great.

Im starting to form a theory here...

I was installing Aqua from a CD. More specifically, I was doing an "lha x cd0:aqua.lha" when it crapped out. I never needed DiskSalv before so it wasnt on my hard drive. I had to burn it to a CD and try to run it off that... where it also guru'd. Im now getting errors from CDs where I put a CD in and get a CD0:? icon (on known good CDs). I was trying to copy DiskSalv from CD to hard drive, and it doesnt even see the CD as a valid filesystem now.

The CD drive is on the same SCSI chain as the hard drive.

I wonder if the CD drive is hosed, and the validation problem the result of the system resetting in the middle of writing out an LhA's contents to DH0:...

I'm going to see if I have a spare SCSI CDROM here, and try a swap.

I dismantled the computer (stupid case design making it necessary to rip out all cards to get to screws that hold in CD drive!) and swapped out the CD... as an added bonus, I found a 32X SCSI CD drive in my closet, as opposed to the 12X in there when I got the computer. The OS now could see the DiskSalv CDROM. I copied the files to DH1: (which isnt giving errors) and ran the Install script, installing DiskSalv to DH1:DiskSalv. Its running now, doing a Validate on DH0: and on like the third pass (Hash Check) it found an error, on one of the Aqua files in DH0:tmp/ which is where I expected the error would show up. When running DiskSalv before from CD, it never found any errors.

I cant say 100% for sure the CD drive I had was the problem, but it seems a good candidate. Now I just need to wait a year or two for DiskSalv to finish running and fix the errors. Hopefully it doesn't guru out again haha.

{bleep}ing guru'd. Argh!

In the interest of beating a dead horse, I'm giving DiskSalv one last try, in Repair mode. If it fails, I'm giving up on it and trying something else.

Given that I know where the error is... Anyone know if removing the file would fix the error? I cant in Amiga because the partition isnt validated. Say I mount the SCSI drive in Linux and remove the Aqua directory though, then put it back in the Amiga... might that force it to clear up?

If nothing else when I have it under Linux, I can do a full backup so if all else fails I can wipe and reformat. It will be a real pain in the ass to take it apart and put it in my PC though, so I pray to the Amiga Gods that this last DiskSalv attempt works.

Letting it run overnight in Repair mode did the trick.

Anyone wanna buy an awesome broken CD drive? hehe
