How to recover an overwritten file?

[Patkos Csaba]

I must recover a very important about 1GBytes archive which was overwritten accidentaly. I use mandrake 10.2 and fstype is ReiserFS.

If you know some useful tools I can try please help... it is very urgent ... should be done by tomorrow...

 

Thanks a lot.

Google found this link but I have no experience with this software.

Unfortunately , other products that are available cost money.

ix, the product on your link does not seem to support reiserfs. this link seems to provide some feedback on how to do it but still gives no guarantees.

 

ciao!

Overwritten or removed?

 

Either way, your chances are pretty poor, and I know no software capable of recovering from reiserfs, leaving your only hope to be a professional data recovery service.

Thanks for all your replies. After all the datas were recovered from another backup. Anyway, I had no succes recovering the overwritten archive. It seemes impossible. That's it. Thanks again.

Overwritten

if that the case, for any file system, this is the end, is it not?

 

Heard of recovery that can look at the remanant magnetic field so even if file is overwritten then there is still something there. Do not know if this is a folk story! I suppose the magn field takes more room than is really necessary for 1 bit, so with the right magnetic probe you can do some work looking around where each bit is.

 

Link to reiser look excellent

 

Was going to suggest dd, ddrescue and foremost

(in the sense that 1st thing to do is to make a backup)

I use a recovery service for data that I cannot recover in simple ways. The service can get anything that has not been obliterated by a write. Even a format and partition can be recovered, as long as the drive was not zeroed in the process. ;) (That is why, when a client asks for full erasure of a drive, I zero the entire drive.)
