[DEMUG] SD Camera Disk Repair

[Dwight M. Lanpher]

Dear Group:

I have a 1 GB SD Camera disk that is partially corrupt.. probably a bad
format or a bad section of memory. This disk contains the last day of a
vacation in Europe and I would very much like to recover the data.

I am able to see and copy the first 71 pictures off the card but Disk
Utility indicates that there are 512 files on the disk: Get Info indicates
817.8 Mbytes of data on the SD Card but it also indicates that the one
visible folder only has 160.2 MB of data.

Format :     MS-DOS File System (FAT16)
Capacity :   962.4 MB (1,009,128,448 Bytes)
Available :  144.3 MB (151,339,008 Bytes)
Used :         817.8 MB (857,522,176 Bytes)
Number of Files :  512

Disk Verify indicates many errors of the type:

Extend? no
/DCIM/102CANON has entries after end of directory
Truncate? no

Does anyone have suggestions for specific recovery software? I¹ve used Disk
Warrior on hard disks and think that it might be a good candidate for
recovery as it recovers the actual data files and reconstructs the
directory. 

But, I don¹t know whether Disk Warrior can deal with a SD Card. I¹m using a
PCMCIA card to read the disk and it mounts very nicely in Disk Repair.

I¹ve tried making a disk image but only the 71 files appear so I believe
that I¹m going to have to work on the actual disk and not a copy so I don¹t
want to make a mistake. I¹ll probably have only one chance to recover the
data.

Fortunately I used several cards so that I¹ve only lost one day¹s pictures.
But it would be a major expense and another trip to reshoot the pictures and
video so I would be willing to spend some money to recover the data. I
believe it¹s still there and with the right software it should be easily
restored. I would even consider sending out to a data recovery service.

Any suggestions?
