The basic problem is quite simple - the partitions ain't there no more. > > also, you're giving a layout which is I suppose in cylinder units. sometime > weird things happen if you allocate partitions (or logical volumes) giving > partitions extents in other units (MB). you should have to remember how you > initially allocated and use the same unit, if you want to have a chance > getting a good mapping. The initial allocation was done using Druid while perform the RH72 install, so knowing Druid anything could have happened. > > what I'd do just before cryin' for mum' whould be to write a script (you > said that you had an up'n running linux on hda) that would create a > partition on hdb from cylinder X to last one and call mount (-t e2fs), > looping from 3 to last - 1, and stop if the mount succeeds (this should > happen only for your old / and /home).

This won't work because the mount would fail because the current and predefined sizes don't match. The script we did write simply called dumpe2fs which just looks at the superblock and returns information about the partition including the size. That script didn't find anything. However, I have downloaded testdisk which is a partition finder/undeleter so I'll try that one tonight. > > good luck > Ta, I need it > > > ... > > >We then decided to physically swap the drives making the Windows disk > > drive 1, and then re-install windows from scratch.
