Re: ext3 partition recovery (Again)
Hi,
I feel strongly that this problem is recoverable, however you will have to
construct a manual partition table using the Linux Fdisk. With a lil bit of
guess work and a lil trial and error I think you should be able to recover
the partitions and data within.
I think you mentioned you used gpart, did you write the partition table after
using gpart i.e. with the gpart -w option?? I don't think that will help but
I want to know if after doing this were you still able to access the other
partitions.
Also mention the partition sizes for each of your partitions as you remember
them and your total hard disk capacity.
Bye for now
