Toshiba external hard drive mac read only

Permissions not ignored Being a multiuser operating system, OS X sets up access permissions for all files and folders on the system, including external drives, which are merely accessed as a folder once attached and mounted. Since permissions are set up through account UUID and UID numbers, if the drive is used with different systems, it may have permissions associated with it for accounts that your current system does not recognize, or even odd permissions settings that can prevent access to the files on the disk or to the disk itself.

This may happen even though getting information on files and folders shows you ought to have full access to the drive. To prevent such errors from happening, OS X includes a setting to ignore permissions on external drives, so all files on the drive should be fully accessible regardless of their permissions settings. To set this option for external drives, select the drive on your desktop or in the Finder sidebar, and then press Command-I to get information on the drive.

In the information window that pops up, go to the Sharing section and click the lock to authenticate. Then check the box to "ignore ownership on this volume," or toggle it off and then on if it's already enabled. If this setting is enabled and you still do not have access, you can try removing the system's volume information database, which holds this setting for external drives on the system. In here, locate the file called "volinfo.

The link has been hacked and goes to avangate software. Type the link manually gets to the correct place!

Solving the "Read Only" External Hard Drive Problem on Your Mac

I'm sorry my article wasn't the help you were looking for, but I'm glad you figured it out! We take cables for granted, it's often the last thing we'll think of. Bought Paragon, installed, finally read users manual that admitted that Paragon does not work with Yosemite. One way around it is to create a symbolic link or a shortcut on your Desktop.

How to fix read-only external hard drive after High Sierra update?

Good luck! However, I have a small problem. Though I can freely read and write on my external hard drive, I can't make other changes to it, such as renaming it. When I click on "Get Info" of the hard drive, it shows that I have custom access. Is there a way that I can change my status to administrator so that I can rename my hard drive? I have to say: I've no idea. Are there other changes you're trying to make, or is it just the name thing? It's just the naming: So far I haven't encountered any other problems with that custom access.

Thank you anyways: Thinking about this more, I suppose you could try disabling all the tweaks you made, then changing the name, then re-enabling them. If you want. Likewise, it was upsetting me so much, as I used PC and am now stepping up on Mac in addition, and I was guessing there were incompatibilities. Thanks so much for taking the time to help by posting, it makes a difference. Sadly Apple file sys is not supported by my TV and other usb readers. Oh I didn't know that.

This is not working on my Mac, it used to, but now I have to turn paragon off to access my seagate hard drive, and even then it's only read only. FAT32 is such a crappy filesystem and it's a shame there's no filesystem with full default support by the main 3 OSes.

Then there's exFAT which is more geared towards Flash drives as opposed to spinning Hard Drives, but you need to install an extra package in most Linux distros to get it to work. FAT32 has a 4 GB file limit, which is annoying on large drives. High res or long videos. I often record videos on my capture card that are hours long, and they can be over 4 GB, and I need to transfer them to my Desktop.
