PFS3 ... DDH0 ALERT Wrong index block id?? SOLVED!!!

[A4000_Mad]

Hi,

When I switch on my A4000 with 9GB SCSI hard drive it displays a PFS-3 Requester window:-

Device DDH0
ALERT
Wrong index block id



I click on OK and it fully boots then displays another PFS-3 Requester window:-

Device DDH0
Disk update failed



I've tried using pfsdoctor in both Check and Repair modes:-

Initialising
Checking rootblock
Checking rext
Starting pass 1
Checking anodetree
ERROR: block outside reserved area
ABORTED


All looks well inside the Workbench partition DDH0, but I get a report that "Volume is write-protected" if I try to write to it. I have also tried to do a quick format of the partition, but this is not possible as I get the write-protected report again.

Any thoughts on this please?

Maybe change the partition's filesystem to FFS, quick format, then change back to PFS3, and quick format...?

That was a rather clever, cunning plan thanks mate :-)

PFSDoctor should be able to fix the error

Yes, that's what I thought Thomas, as it fixed my only other problem ok. Many thanks for your other suggestions :-)

With my data backed up and nothing to lose, I thought I'd see what the other buttons of pfsdoctor did. First I tried 'Search filesystem'. But this didn't progress and caused the A4000 to reboot after just a few seconds.

Then I tried 'Undo Format'. To my surprise this scanned DDH0 making lots of repairs and renaming it as "FixedDisk".



It also recommended that I backup my data, format the disk and then copy the data back to it. So I did just that and all is well now :-)

Thank you.
