I had an 800K HFS disk on which the master (top level) directory got trashed. It had ~50 files/folders in it and it just died. Here are the replies I have gotten so far. There also is a current ongoing discussion on this topic, so check other posts around this date for more info. My comments are below the text of the posts. From: princeton!phoenix.PRINCETON.EDU!pswisnov@seismo.CSS.GOV (Peter S. Wisnovsky) Apple's Disk First aid might be able to help you. If you erase the block that is damaged using Fedit (copy a blank block on top) and then run disk first aid it should be able to recover it. Sorry, DFA can't deal with any disk it can't mount, and disks without Master Blocks can't be mounted. -------------------------------------------------------------------------------- From: preese%lapis.Berkeley.EDU@BERKELEY.EDU (Phil Reese) The easy way, albiet expensive in terms of phone call money. The local BMUG group here has a disk #50a and #50b which will allow you to get your files back. In brief what it does is to convert the disk to a MFS disk by copying special tracks from #50b onto a sector copied version of the trashed disk. Now that it is MFS you can turn Fedit loose on it and it should recover all the files. This works very well!! Now how to get the disks? You can try to locate the Late Fall '86 BMUG Newsletter and look at pages 57-64, the article File and Disk Recovery for Just About Anyone, A Biginners Guide, by Steve Costa. If this doesn't freighten you away then give BMUG a call after about 2pm PST on their help line 415-849-help. Sorry again - I manually made the disk MFS by copying track 0 from an 800K MFS disk (made by intting with a pre 3.X system) and it just made the disk appear blank the the Mac. -------------------------------------------------------------------------------- From: Maurits van der Veen <teiltje%dartmouth.edu@RELAY.CS.NET> As far as I know tags are present in each sector, also on HFS disks. FileFixer seems to be quite good at finding them, and recovering files, as long as the disk is not too trashed. FileFixer 1.0 thrashed on the disk for 5 minutes and did nothing. From: peter@entropy.ms.washington.edu (Peter Guttorp) I had what at least superficially seemed to be the same problem, and just got the latest update (4.5) of MacZap. In my case CopyII and Fedit didn't help me, but two disks out of three with thrashed directory block were recovered. Previous versions of MacZap could not handle HFS files. AHA! MacZap for HFS seems to be the defacto recovery method. Now all I have to do is buy it... I'll post the results of that at a later date. Marc Pawliger mp1w@andrew.cmu.edu mp1w@cmuccvma.bitnet
