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, copy & paste them to my desktop. But I can not 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 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.

You can buy Tuxera NTFS and download onto your Mac. there is a 14 day trial free period and then you can buy it for £15. Then can instantly download on to hard rive from Mac. Much easier than doing it yourself.

You could try burning a few DVD's with the data to back it up first if you can''t get another HD to hold the files even temporary.

As to fixing the problem, first make sure you have a backup as you might loose a few files in the process. Try running Apples' Disk Utility program first verifying the disk and then repair it if needed. Then try fixing the permissions again first verifying then repair it.

If you still have problems you may want to try a 3rd party app like Disk Genius It also can defragment the drive as well.

The last option is to reformat as you already know. - Good Luck

If your Toshiba hard drive does not give you the paste option, just follow the steps:

1. Save any file in your hard drive Toshiba in any source

2. Open Finder

3. Go to applications

4. open Utility folder

5. Go to Disk Utility

6. Select on the left of your window your Toshiba Hard drive

7. Select format: Mas OS ( journaled)

8. Click on Erase.

And that's over. You can then paste what ever you on your hard drive. The name of your hard drive will, obviously change to Untitled. You can later rename, if you want.

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.

Good point! But I get a different error when I try to copy files to a NTFS volume. If that were the case he can get a NTFS mounter extension to allow his Mac to read & write to the NTFS volume. Its possible he had this and for some reason the extension is no longer working which could explain the odd error. I would still try to fix the disk first under Disk Utility as I had outlined above. It will also show what the drive was formatted with putting his mind at rest.

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.

I'm working from a very low storage space laptop. I dont have another hard drive to move my external files to (270 GB worth) and then reformat. Is there another solution that doesnt require moving files to and fro?
