i have deleted my partition table
 

I accidentally deleted my partition table using the dd command after I discover what have I done I used hiren ->hd partition programs ->magic partition I found the the entire hd is seen as a deleted partition
I must recover this partition table is there is any way to undo the dd command or to recover the partition table

I had 3 partitons
Hda1->9.3 gigs ext3 fs
Hda2->10.5 gigs ext3 fs
Hda3-> 54.5 gigs ext3 fs

Ps:I used a program in hiren cd called Test disk it found the lost partitions but I am afraid to add them cause I don’t want to over write any data should I use it or there is other way


thanks

If you have kept a record of their sizes just repartition the same and all the data will be with you if you haven't dd beyond the first sector.

Using the Testdisk program may also help to rebuild the partition by examining the filing structures but the success is not guaranteed.
