URGENT - data recovery help needed


I certainly feel dumb right about now.

I accidentally ran mke2fs on the wrong partition, and all my vital data is no longer accessible. mke2fs was run with the -c option, which does read checking (but not write checking). As soon as I realized I'd created a filesystem on the wrong partition, I unmounted the drive and re-mounted it read-only. I then made an image of the raw disk data and saved it on a seperate hard drive in case I end up ruining the original somehow. I checked the disk image with a text editor and found that all my data is in fact intact, but I have NO clue how to retrieve it. I REALLY need this data back. Without it, I'll likely get fired within a couple days. Can anyone help me figure out how to retrieve the data?

Thanks,

You're about to learn a very important lesson, I feel.

There's two types of data:

1) Data you have on a tested backup system
2) Data you don't need.

If you know what the partition table was, you may be able to recreate it that way. Otherwise take the disk to a data recovery expert. There's plenty of the services advertised. It'll cost you have it recovered, assuming it's possible. But that's better than losing your job, right?

Regards

The Computer Science Prof at a local college might be helpful, or an assistant. He may be very short of time and feel very overworked but with a correct approach and full explanation of what happened... he may be willing to help or could possibily point you to some one that might have the expertice/tools needed for what you seek. Back-up's are your friend. But I cant judge anyone untill I heed that same advice.

The irony of it is that I was installing a new hard drive to use as my new backup location (I'd run out of places to store backups). The drive was all ready and fdisk'ed, and when I went to type mke2fs to make the filesystem, I mis-typed the device's name and ended up making the filesystem on the drive I intended to backup all along.

I've been trying to get in touch with Ontrack Data Recovery (they *might* be able to restore the files remotely), but apparently their "emergency hotline" doesn't reply very fast. I've been waiting 8 hours. Good thing I'm not in need of life-saving first aid...

Meanwhile, I'm still looking for a local solution, but no luck
