3385.0. "HARD DRIVE PROBLEM" by CGHUB::ROY_R () Wed Jan 24 1990 01:49

    I have an 80 meg HD that has just sprung a leak.  Can anyone tell
    me how to correct the problem, hopefully short of reformatting the
    entire disk.
    
    When I boot the system I get an error message "ERROR VALIDATING
    DISK, KEY 67546 ALREADY SET", I hit cancel and the system continues
    to boot and everything seems ok! however, when I go to duplicate
    the empty drawer it gives me a message "VOLUME BOB IS NOT VALIDATED"
    and will not duplicate, also I cannot delete files from any directory
    using CLI or wastebasket (for the same reason).
    
    I asked for INFO.  it came back with DH1: size 68M  errs 0  status
    validating.   DH0: size 1.2M  errs 0  status Read/write and the
    same for RAM.  Cany anyone give me an answer to what happened and
    how I might  fix it.
    
                                                      Thanks
    
                                                         Bob

	Re: .0 Before your troubles started, your system crashed (or you rebooted or powered it off) before AmigaDOS could write to the disk the bitmap that describes which blocks on the disk are allocated. Next time you booted the system, AmigaDOS noticed the disk was in an inconsistent state, and tried to "validate" the disk. The disk-validator scanned every file on the disk to determine which blocks were allocated and which were free. The disk-validator ran into a problem, two different files thought they contained the same block (AmigaDOS file systems call blocks keys). So the translation of the message is, "ERROR VALIDATING DISK, BLOCK 67546 APPEAR IN TWO DIFFERENT FILES". Since the file system data structures on the disk partition are broken, AmigaDOS refuses to allow you to modify the partition (seems wise). Note that only the partition that AmigaDOS is complaining about has a problem. If you have two partitions on the disk, the other partition is OK. You don't need to low level format the disk; you need only worry about the partition with the problem. Possible solutions: If you were a file system wizard, you could use some program like DiskZap to modify the individual blocks on the disk to "repair" it. You can run DiskDoctor on the disk. The odds are good it will fix the disk without you having to backup and restore the disk. You can run DiskSalv on the disk. The odds really great that it will make an intact copy of the disk on another partition. You can backup the partition, AmigaDOS format the disk, and restore it. My personal recommendation: Backup the partition, AmigaDOS format the partition, restore the partition. It takes longer, but isn't the peace of mind knowing that everything is completely OK worth it? Second recommendation: Back up the partition; run disk doctor on it. Living on the wild side: Just run disk doctor. Macho, or just crazy: Get out your copy of DiskZap and edit away. While you're at it tonight, go ahead and backup any other partitions on the disk.

	If you decide to back up the partition, make sure that you back up all the directories. When I had a problem with validation, Quarterback and directory commands did not recognize all my directories. I could cd to them, or specify them manually for backup, but (for whatever reason) it wasn't automatic. Steve
