------------------------------
Technical information: I have an Amiga 500 with a Phoenix PhD 48 meg hard
disk. I'm running the ARP shell (ASH) with Conman and the 1.3 ARP commands.
------------------------------
I tried a write command to one of my hard disk partitions, dh1: by name,
that my system didn't like ("move a.b a:b" where a: was a logical assignment
to a subdirectory of dh1:). The hard disk commenced to chitter violently, so
I rebooted.
From that time forth, dh1: has failed to validate. I get a requestor saying
Disk Validation Error
Key 8151 Already Set
and have to cancel the request to validate in order to bring up the system
at all. In consequence, the rest of the system has been ok, but dh1: is
only available on a read-and-execute-only basis.
What should I do to correct this problem? Do I have to reformat the hard
disk? Can I reformat dh1: alone, or will dh0: also be affected by any
reformatting? Is there a less radical solution to this problem?
Thanks.
Sincerely, Mark Steinberger
P.S. Is Key 8151 any relation to Catch 22?lphillips@lpami.wimsey.bc.ca (Larry Phillips) (05/23/89)

Perhaps you mistook the normal seeking you get when copying a file to a different place on the same physical ldisk. Perhaps there was another task using the disk at the same time. At any rate, it's seldom a good idea to reboot while there you are performing write operations. In most cases, you will do more harm that wy than if you just let the operation run its course. >From that time forth, dh1: has failed to validate.

There are, currently, other solutions. The 'key' referred to in the requester is the number of the disk block, referenced to block 0 (cylinder 0, head 0, sector 0 of _that partition_. The 'key already set' part means that there are two pointers to key 8151 in the directory structure. A sector editor, a knowledge of the Amiga's disk directory structures, and a lot of work is one way. Another possibility is DiskDoctor, though I still don't trust it fully. Some folks have been reporting good results with it lately. Other than that, there is not much else to be done except to format and restore. -larry -- - Don't tell me what kind of a day to have! - +----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca or uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 | +----------------------------------------------------------------------+
