Reformating without losing data?

[lynkynpark86]

On my hard drive (640GB) I have 3 partitions, one being time machine, the other two being storage. The drive is in Mac OS Extended (Journaled). I need it to be in FAT-32. Can I change formats without erasing? If I can't, how can I back up the 640GB of data on the drive when I've got a 120GB computer that's already full? And can you partition a FAT32 drive?

no.

If I can't, how can I back up the 640GB of data on the drive when I've got a 120GB computer that's already full?

get another external.

And can you partition a FAT32 drive?

yes.

FAT32 has a limitation, though, in that files cannot be bigger than 4 GB. you might want to use NTFS instead.

Also, if you intend on continuing to use the Time Machine partition for TM backups, it needs to be HFS+

Why does your HDD need to be changed to FAT32?
