Help with thumb drives and SD cards

[farqueue]

Hello people, i have a perfectly working well mp3 player thumbdrive 1gb and a SD card reader with a 512mb stick in it.

All was working fine until one day when mac os x:
1. Doesnt let me write or edit files on my 1gb mp3 player
2. Does not detect my SD card reader with a 512 mb sd card, but detects my mp3 player

When i go to my sisters place, these two devices above work perfectly ok.... windows detect them etc...

The disk may be formated in a Windows format that Mac OS X can not write to. Mac OS X can read the Windows file format NTSF but, it can not write/edit files to that format. However Mac OS X can read and write to the FAT32 Windows file format.
