recovering MOV files from an erased microSD card

[Klaus Hildner]

Hi all,

 

On Windows 7 (evaluation), I am using Recuva with an MicroSD card (8 GB, FAT32) from which I accidentially deleted the sequentially named movie files (FILE0001.MOV ... FILE0256.MOV).

 

After a non-deep scan, Recuva displays a list of these files, however only detects the first and a few in between and then a bulk towards the end to be "green" recoverable. When I then try to restore all of them, none of them (I tried a reasonable amount, and no preview thumbnails are created in Explorer) can be played in MediaPlayer. (This is not a codec issue -- other movies from the same camera do decode successfully.)

 

Moreover, Recuva detects the cluster size to be 32768 (bytes).

From what I read on http://support.microsoft.com/kb/140365, a 256 MB to 8 GB media should have cluster sizes of 4 096 bytes.

 

What might go wrong here,

and is it possible to enforce the assumption of a certain cluster size?

 

best regards

 

Klaus
