Hello. A customer of mine gave me an SD card which is quite surely failing. I'm trying to recover what I can. I first tried using an USB based reader: altough the SD card should be 4GB in size, dd just copies 121MB. So does recoverdisk. "camcontrol readcap /dev/da3" gives: > Last Block: 248319, Block Length: 512 bytes which agains means about 121MB. I put the card in another box and i get: > mmcsd0: 127MB <SD 0.0 SN 00000000 MFG 00/0000 by 0x0000> at mmc0 0.4MHz/4bit/65535-block Is there any way I can get beyond this 121-127MB limit and read what I can of the rest? I looked into camcontrol's man page, but came up with no idea. The card should hold pictures, so I could go ahead with photorec once I got an even partial image. bye & Thanks av.
