Arrrgh! My harddisk has crashed, but I think its probably fixable: I was un-arcing a file, and had a system crash, (no suprise, seeing how I had all kinds of things running), but the file that I was unarcing didn't get fully unarced, and when I re-booted, I got: Error validating disk Key 18036 bad header type But it still boots (after I hit cancel) So I whip out diskx, and look at block 18036, and yep, it's the file header for that file. So I figure all I gotta do it fix or delete that file header, (or delete whatever is referencing it), no? How do I go about doing this? (It's a supra 20meg, so I'm using their mounting software 'supramount', in case it matters) I can't just delete the file, 'cause the disk isn't validated (although if it's possible somehow, thats the optimal solution.) Help please!?!? Noel -- NEVER date a music major.

Deleting the file is actually just about what you'll need to do...
Go into DiskX and find the directory block for the parent of the file.
(ie. if the file is in the directory FOO, find the driectory block for
'FOO'...) in this directory block there will be a pointer to the bad
file. Usually this pointer is easy to spot, since it's just the hex valuse
for the file header. (In this case 4674) Sometimes the pointer is chained
behind another file. Just edit the directory header to take this pointer
out. (Or edit the last file in the chain before the bad file...) then exit
DiskX and do a 'Diskchange'. The validation should then free up the blocks
no longer used for that file.
