I've got a 32 gb thumb drive the other day as I need to transfer files between pc and mac. Now, the drive is now formatted in FAT32 and both computers can read / write on it. There is as we all know a 4 gb file copy limitation on FAT32 so I formatted it in NTFS but now I can read files but can't write any while on the pc it works ok. When I format the drive to MacOS X format, then it's not visible on the pc. Is there any way to sort this?
