deffinatly sure and it was always ntfs. cant back it up band convert to fat32 because i dont have a nother drive with 500gb of space as my drive is very full
so can anyone help
Mac can read data on NTFS partition, but it can't write to it.
You cannot format a 500GB harddisk on FAT32 as FAT32 has capacity limit of 32GB which is why large external HD are in NTFS if it is preformatted for Windows use. So converting from NTFS to FAT32 is not possible without leaving unformatted space or when your data exceeds 32GB.
I recently migrated from Windows to Mac and had the same issue. But I had 2 external harddisks and an almost empty one in my Mac, so I copied the data out of the external hard disk, reformatted in fat32 and copied the data back. Now the drive works fine on Mac OS, XP and Vista.
http://en.wikipedia.org/wiki/Fat32#FAT32 => showing 2TB as maximum file system size.
Otherwise we might soon see a serious limitation for memory cards. Most cameras (or rather all?) work with FAT32 when storing images.

exFAT, on the other hand will support files of upto 2TB, but doesnt have the same type of data security as NTFS. This is supported by MS in XP SP3 and Vista SP1.

theres only one proven way to convert NTFS filesystem to FAT32 without distroying the exisiting data--Partition Magic.
but at US$70, it cost more than a new 500GB HDD. not to mention the risk of losing data if ANYTHING goes wrong during the conversion process.
so just get a new 500GB HDD, transfer the data and sell it away if you don't need it later. the most you lost is $20 but guarantee to have your data safe.
Here's another suggestion. Dump the Mac. Save you all the trouble.
fyi, i use my mac to write/read on NTFS, as per the above posters link.
