Scripted run syntax help

#1 Post by stumpyuk » 19 Sep 2012, 11:56

I am trying to script out a command to carve a partition with the blocksize set to 512, here is my command:

Code: Select all

photorec /log /d unallocated /cmd /dev/sdc1 fileopt,everything,disable,txt,enable,freespace,blocksize,512,search

Here is my log:
Failed to set locale, using default 'C'.

Command line: PhotoRec /log /d unallocated /cmd /dev/sdc1 fileopt,everything,disable,txt,enable,freespace,blocksize,512,search

I notice that in the log file, it indicates that the blocksize=2048. Is this just letting me know that the cluster size is 4 sectors or have I got the command syntax wrong? I want to be sure that the command successfully set the blocksize to 512 bytes.

The blocksize returned from "freespace" was overriding the value you specified.
I have uploaded a new 6.14-WIP. Can you try it and tell me if you still have the problem ?

Thanks Christophe, that version seems to work, the blocksize was reported as 512 bytes.

Thanks again!
