Cannot Write to HFS Plus USB External Hard Drive
 

Hello:

I am definitely a Linux Newbie.

As a secondary backup procedure, we store video and audio files on 1TB USB External Hard Drives formatted HFS Plus. Some of the drives are no longer writable.

We receive the following message when attempting to copy or move files to the USB Drive: "Could not write to /mnt/USBDrive/FileName"

In root, I have tried the following recommended commands:

chmod 777 /mnt/USBDrive
chmod -R 777 /mnt/USBDrive

I have also tried to change Permissions in the Permissions Tab but I receive the following message: "Could not change permissions"

It was also recommended to me to disable the "journaling" feature within disk utility in Mas OSX. This did not make a difference.

Here is the information on the drive when I type mount:
/dev/sdl2 on /mnt/USBDrive type hfsplus (rw,nosuid,nodev)

I would greatly appreciate any help on this.

Thanks,

RJReding

Make sure that HFS plus is supported by your distro..
You will be allowed to copy files only from the account from which you are mounting the hard disk.

Thank you for your response.

Since I am a Newbie, please explain in detail what this means and how to resolve.

Thanks in advance.

does your hard disk open after inserting it to the computer?
sign in a particular account in linux.insert the hard disk and try copying files.
if it does not work, then try formatting it in vfat by the command
replace sdb1 with the device name given to your device by your system.
do this after unmounting your hard disk(right click on the hard disk, select unmount).

The USB drive mounts and I am able to copy files from the drive. I just can't write to it. I have several of these drives. There are a few of them that you cannot write to anymore. Is there a solution that does not involve reformatting?

Thanks,
