re-add deleted extended logical partitions?
Help! I inadvertently deleted (using fdisk) two ext2 partitions that are in an Extended primary partition (i.e. they were /dev/hda7 and /dev/hda8). I've done nothing since then but a lot of reading. Can I safely add them back using fdisk or sfdisk (or cfdisk or something else? I know their physical locations and sizes and have verified (using a nice tool called gpart) that they're apparently still intact. If not, how can I find and update the extended partition table without modifying the partitions' contents? Thanks in advance.

Yes, if you have the exact partition geometries you can just add them back as long as you haven't created anything else on top of them since. David Coe wrote: Help!

Re: re-add deleted extended logical partitions?
Thanks, that worked beautifully and all is well again. I highly recommend gpart -- it did an admirable job of telling me where those deleted partitions actually were. I'll see if I can debianize it if someone isn't already doing that...
