How do you add files from a Mac to my Toshiba external hard drive.

Put copies of them onto a second drive. The one you have will eventually fail.

what Niel said....anyways, yes, you'd probably need to reformat the Toshiba External hard drive to MacOS Journaled, and yes, this would make the files on that external drive delete. Here's how:

1: plug in old drive, get files off of it

2: reformat as MacOS Journalled (for Mac only use) or ExFat (for both Mac and PC use) . Use Disk utility for that.

3: plug in newly reformatted drive and transfer files.

If you're worried about failing hard drives, it might be a good idea to have a backup system in place and use it regularly. As Niel pointed out, hard drives can and do eventually fail, no matter what computer you may have, and they usually do so without warning. I don't want to scare you, but it does happen. Any hard drive should work for backup, and with Time Machine built into your MacBook Pro, it's almost effortless. oh, and make sure you have show external hard drives turned on in your Finder prefences....that should help you

good luck

Once you save all your files to another location, since you'll be working only with Macs, using Disk Utility select the HD and repartition it. You'll want to create a new partition, click the Options... button and select GUID partition table (your drive has a Windows-compatible Master Boot Record), and give it a Mac OS Extended (Journaled) format. Note that the GUID partition table is best for Time Machine to work.
