not mysteriously ..
if hda5 was your extended partition ... than all subsequent
logical partions will go pooff when you delete the (reference)
extended partition

as long as oyu didnt write any new data to the disk, your
partitions are still there ... nor format the partitions

guess .... lots o guessing ... or start using a specific
partition scheme that doesnt change .. night or day or
any other whacky reasons why one partition is better than another
for restoring ... your ext4 is probably end-hda3+1 till end-of-disk
was logical hda5 starting from n or m ... till o or was it p
was hda6 starting from o+1 till p or qq
was hda7 starting from p+1 till q or rr
...
if you followed a particular partition size creation pattern,
+2M, +10M, +10M for your partition size, fdisk might get you
back to the right cylinder start and ending info again
- run e2fsck on the partitions after you recreated it
- if its happy .. backup your data to new backup media
and double check your paritions and boundries again
( or reformat to make sure the cylinders stop/start is
( at the rirght places and restore from previous backup
for the future...
- save a printed copy of the partition tables taped to the disk
fdisk -l /dev/hda | lpr
( no point in storing the partition info on the same disk
( if the partions gets whacked
