Another plea for help. A while back my hard disk had to be sent off for repair (it needs it again <sigh>) so i made an image backup using David Small's Meg-a-minute Backup. My drive is partitioned into 4 roughly equal partions of 5meg each with the 4th partition just a big scratch area. Well, i didn't have 28 disks (only 21) so i decided that the stuff in the fourth partition (dimension?) could just fade into the twi-light zone and i backed up partitions 1-3. Ok, i get the drive back (they told me it was a new drive and i believed them until the problem reappered and i checked the serial numbers) and I reformatted it. (well, being a hard disk neophyte, i never wrote down the sizes of the original partitions (or if did, i sure don't know where i put them). I tried to do it from memory and then i restored the images of the first three partitions. I must have guessed wrong and partition 3 overwrote part of partition 4 so, now, whenever i try to access partition 4 the system hangs ( i have to press reset ). Does anyone know how i can revive partition 4 to the proper size without destroying any other information on the disk? I would appreciate it very much and hold you dear to my heart for the rest of my life (well, for the rest of day at least!).

Looking at the source to Meg-A-Minute program, it will _not_ let you restore a partition into one of a smaller size... only a smaller one into a larger one (and then making the excess space unusable, by the way). So there is no way that the Meg-A-Minute program wrote any given partition's sectors into those assigned to the next partition. And to find out what sizes those old partitions were, it is rather easy to start the RESTORE process with the backup disks and go through the process until it shows the partition information for those particular backup disks. Then cancel and do the same for the next series of disks (next partitions). Just write down how many sectors in each partition. 1 Meg is 2000 sectors if I remember correctly. Then reformat the drive and all should be well!! If you have the backup disks, this works fine, if not, oh well. Salvage what you can and start over.
