PRS-505 Format - FAT or FAT32?

I don't understand what FAT is/does, but could someone advise whether it's best to format to FAT or FAT32?

Thanks,
Wen

Mine (my PRS-505) shows up as FAT (not FAT32).

Standard is FAT32 for most stuff not using NTFS... i.e. memory cards, internal memory on readers etc... recognised by PCs, Linux, Mac OS etc.

FAT32 can use bigger drives and files than FAT, if I remember right.

^ yup.

From Wikipedia:

FAT16 [aka commonly known as FAT]:
"...thereby fixing the "definitive" limit for the FAT16 partition size at 2 gigabytes"

FAT32:
"Cluster values are represented by 32-bit numbers, of which 28 bits are used to hold the cluster number, for a maximum of approximately 268 million (228) clusters. This allows for drive sizes of up to 8 TiB with 32 KiB clusters, but the boot sector uses a 32-bit field for the sector count, limiting volume size to 2 TiB on a hard disk with 512 byte sectors....

...The maximum possible size for a file on a FAT32 volume is 4 GiB minus 1 byte or 4 294 967 295 (232−1) bytes. Video applications, large databases, and some other software easily exceed this limit. Larger files require another filesystem."

I went with KennyC's advice to be on the safe side.

And my comatosed 505 has finally woken up after four days.

Yay!!! I'm so happy.

Thanks so much for all your advice and educating this old numbskull
