Hello friends,
I have Samsung Galaxy Ace and I was using 2BG Sandisk micro SD card in it. Today I thought of upgrading the android version from android 2.2 to android 2.3
I backed up everything (Contacts, messages, call logs, applications) in my SD card. I removed the SD card and got my android upgraded. As soon as I inserted my SD card in phone, it showed that the card is empty, tried with linux, windows pcs, everywhere it requests to format the card.
I checked Internet for solution and found that photorec could help me in recovering my old contact list, .vcf file (which is most important for me). I installed PhotoRec in my linux system and followed all the steps but I am not able to get anything. In starting of program it shows
"Disk/dev/sdb - 32Mb/32Mib (R0) - ChipsBnk Multi-Reader".......................(Where as my card was 2 GB!)
In each trial, application stops with an error "Error reading sector 62464"

Can somebody please help me in recovering my contact list?

Unfortunately no.

Your problem is hardware related. Neither tesdisk or other software solution won't be able to read beyond 32MB limit if controller tells it's 32MB card. You probabely have a controler failure or a flash destroy. Few professionnal company deal with these microflash.
