I just got done de-fluffing my hard drive of that type off error... by any chance did you do some large directory (as in LOTS of files) copies recently? >Is there a utility out there that can help me salvage this? Well, the only commercial thing I know of is Bag of Tricks, but it's pretty archaic and doesn't support any of the GS specific changes to prodos. In fact, it's damn annoying because it stops you on every file that has lower case characters in the filename (which is legal because those bits were reserved when BOT was written). over the last few days I've written a prodos file system integrity checker and repair help package, in Orca/C and designed to use the I/O redirection of the shell. The integrity checker is automatic, but the rest of the utilities are very hands on and you'll need to be familiar with prodos disk structures to use them properly. The repairs I did last night (all last night) were conceptually simple but nontrivial from a software perspective -- it is NOT easy to write a utility that will automatically figure out what's happened when the only symptom is that the index block was never written to disk. I'm convinced that there is a really subtle bug in the prodos FST and how it handles write-deferred filesystem blocks. I am using 5.0.4 and have been since before the last time the problem manifested itself (a backup/reformat done to salvage data damaged by exactly the same anomaly!!). If anyone is interested, mail me -- if there are enough requests I will put a more complete description on the net. Todd Whitesel toddpw @ tybalt.caltech.edu

ProSel Volume Repair works wonders on things like that. It's available from Programs Plus (1-800-832-3201) for $45 (I think). Give that a shot.

I had a similar problem when first setting up my hard-disk under GSOS... I had made the mistake of copying some files to the hard disk using something other than the operating system (such as Copy II+ version 9). I read something about it here shortly after having to "rebuild" my harddisk for the umpteenth time... This is the first I've heard of it since then. randy@oswego.oswego.edu

Though the version of ProSEL that I had at the time was not GSOS compatible. I ended up buying the version that was and have had *NO* regrets... GOOD LUCK... randy@oswego.oswego.edu
