dd'ed drive by mistake

Featured Replies

Hi everyone,

 

I recently tried to remove a drive from my array using the method described here:

 

http://lime-technology.com/forum/index.php?topic=2591.0

 

Unfortunately, I started dd'ing the wrong drive but luckily realized after only 100mb (of the 500gb drive) had been cleared.

 

I've restored the array using the remaining drives, is there a way to mount this drive (separate from the array) and reconstruct the filesystem? Right now the drive is simply showing up as unformatted.

 

Thanks,

Tom.

I'd say you format it and then use reiserfsck with the --scan-whole-partion option to try and recover any remaining files.

Will formatting the drive not delete/destroy the data on the drive? Is there a command line alternative I can use to avoid this?

 

Thanks,

Tom.

Formatting doesn't write anything to the data/file part of the drive, it just creates the headers for the Reiser filesystem. You need a valid filesystem before you can recover anything.

 

If you are really concerned then you should use dd to do a raw copy of the whole drive, assuming you have another drive that size available.
