Unformatting partition


Hi all,

I do hope I find some help here.

When installing a dual-boot system (Kubuntu/Windows) I accidently formatted a FAT32-partion to ext3 using qparted. The partition itself was not changed, that is deleted or recreated. it was only formatted.

The formatting process was rather quick, considering it contained some 20gigs of data.

Is there a way of 'unformatting' ext3 to get back my old FAT32 filesystem including data? I remember such functions from old Dos 3.3 and 5.0 days ...


Any help is GREATLY appreciated

Hello,

Sorry if I am wrong, but I dont know of any unformat utility that will revert you back to the way it was before a format. I know there are tools available that will help you recover lost data after a format for example EasyRecovery. You can use this on an ext3 file system. After you recover what you want, just reformat as fat32 again and then copy back.
I reserve the right to be wrong, but if there was such an animal I would have used it a few times.

Hope that helps.

ps:
What commands are you talking about in dos? I still play with that all the time so I would be interested in this.

If your post is accurate then there may be hope. This is because qparted does not format partitions, it only resizes them. Unless you used mkfs then you did not reformat the partition.

If you only used qparted and did not use mkfs then there is a program called PhotoRec that might recover your files.

I've used it. It works. And it's free.
