Many thanks to David and Karen for their tips on file recovery... Seems my life has become a daily process of going from one calamity to the next. Today while working on one of the partitions on a 46GB IBM Deskstar HDD in a desktop, the system locked up with the drive started making a series of scratchy clicks in the pattern of 4-4-3.
I ran an old version of Norton Disk Doctor which found 4-5 bad blocks and marked them. But the partition was an extended logical D: at the end of the drive right after the C: primary partition, the only other partition on the drive. It took 6+ hours to scan and mark the approx. 6GB D: partition. I really needed that area of data to be a primary partition. So thinking DD had written the info on the bad blocks to a partition table somewhere, I ran Partition Magic (at this point having upgraded to 8.0) to convert the D: logical drive to a hidden primary drive for doing tests with various flavors of Win98.
However after doing the conversion, and then attempting to restore a ghost image to the new primary partition, ghost failed about 3/4 of the way through the process complaining of problems writing to the drive.
I�m now running another 6+ hour surface scan with DD, and am wondering if I�ll have better luck this time.
Is there no way to retain information on just where bad blocks are living on HDDs for use later when deleting partitions, and configuring new ones? I�ve never had problems with physical problems of a HDD before.
Thanx,
Matt
PS: As I recall, there was a problem with these IBM DeskStar 75GXP drives. Wonder if IBM will replace it gratis 2+ years after the purchase.

If you do it manually, you will have to 1) have a copy of the FAT table in hand
2) manually find the first cluster/sector of the file in the FAT table. The
FAT table entry for that cluster will have the next FAT cluster number of that
file. continue until you get to the end. You will then add up/combine all of
the clusters in the FAT chain you just followed into one file, hopefully, the
original one.
That's the boring way - worked for me, but it can take hours to follow all of
the file chains.

www.ontrack.com has another program that works pretty well.
http://skyscraper.fortunecity.com/amd/887/rescue/e_index.html is a free program
that may help.
if nothing else, ontrack.com can usually recover most files you've lost by accident as long as the sectors haven't been overwritten. A couple hundred dollars for their service, but they do do a good job.
