Why can't I add files to my Toshiba external hard drive?

Why can't I add files to my Toshiba external hard drive?

I plug in my 1.5 TB Toshiba external hard drive on a Mac, and I can view my files and copy & paste them to my desktop. But I cannot add any files to the hard drive. A "cancellation" sign appears when I try to drag and drop any type of file. I have over 1 TB of files on the drive with 500 GB of free space left. I would transfer files to another device then attempt reformatting it, but I don't have the time or money to do this. Any help or suggestions? Thanks.

I am using a mac(Love Apple) all you have too do is erase the usb hard drive from the disk utility manager and then eject it, after that your hard drive should work and you can choose permissions and other things as well!

If your ext drive is using Microsoft's NTFS, there's your problem. Back up your files in it, then use Disk Utility to erase and format your drive with the Mac OS Extended Journaled file system. Note that if you use this drive in a Windows machine, you'll have problems with recognition of the new format system.

i had the same issue after I got a new laptop. I did not want to reformat my external -- just add more to it and take stuff off it. To add new photos and videos -- i went up to the New Folder section; made and opened a new folder and dragged (drug?) the photos / videos into folders. It worked!

I did something bizarre and it actually worked. My Toshiba drives' permissions changed suddenly while using it. I am a strict mac user and I was trying to copy footage from an sd card. It really needed to be copied and I noticed that the driver had changed to Microsoft's NTFS. I had access to a window's system and computer (Boooooo) lol so I attached the Toshiba drive and SD card to that computer and copied the footage over. After it was done, I reattached my toshiba drive to edit on my mac and to my surprise my permissions had returned. In short i'd say to try connecting your drive to a Windows system then backt o your mac to see if it helps.
