I need help syncing my external hard drive

[emilyysometimes]

I bought a Toshiba external when I had a PC, but I can't figure out how to reconfigure it to load and unload files onto my MacBook Pro OS X. Any suggestions? I would hate to buy yet another external.

Have you tried re-initializing it for the Mac OS, using Disk Utility?

I'd suggest HFS+ for the format, and
GUID for the partition table.

Doing this WILL erase everything on the drive.
Be aware of that!
