I have a 250GB external hard drive and I need to backup my PS3 files. Apparantly the PS3 only supports FAT32 format but my HDD is NTFS by default and can only be changed to exFAT, which I have tried but still doesn't work. Is there a way to make it compatible with my PS3?

Thanks
I already have formatted it to exFAT. This and NTFS are the only options available. I either need to know if there is a way to make it FAT32, or if i can make NTFS or exFAT compatible with the PS3
