On the beginning I appologize for my english.
The goal is,
based on information available on this forum, a couple weeks ago I wrote simple program:

Purpose is to read a value from file, increase them and write back to file.
After some time playing with this code, my SD card (new 2GB Kingston) became no more visible for Primer2. So I try format them outside the Primer2, first message after "format x:" was "format them with /FS:FAT32 option" so, I follow this suggestion.
After that Primer2 and SD card works fine so I back to my program, and again, may by after 30-50 succeeded runs SD cards dissapear again, I'm afraid this time forever - command "format x: /FS:FAT32" returns the message:
Type the file system is RAW.
The new file system is FAT32.
Check 0m
You can not specify the number of sectors on the volume.
Is my program damages the SD cards, or I just not have luck buying them?
Is there anyone who bump into the same problem?
Any suggestion will be appreciated.
