External hard drive turned to read only when I installed Os X el capitan

Hi Everyone,

This morning I put some files on an external hard drive. At about noon I installed The new Os X El Capitan and since then the hard drive has turned to read only.
It is the NTFS formatting but since there was no problem this morning I wonder what happend. I can not reformat the drive since I have insufficient space on any other computer of hard drive I own.

Since it worked fine this morning and it doen't now I think there is a problem with the new os, but i can be wrong of course!

I hope somebody has a fix

Kind Regards,

Tim

OS X El Capitan (10.11)

You likely had some third party app running that allowed use of an NTFS drive. OSX regardless of version can not write to NTFS formatted drives without you installing a third party app.

Hi,

I have an external 1TB ADATA HDD which is already ExFat. Before upgrading to OS Sierra everything was fine with the permissions, but when I tried to use the HDD with applications such as Plex after the upgrade, it became unavailable. Moreover, when I go to the Get info, under the permissions tab it's written that I have "custom" permissions (I am able to read and write from Finder but otherwise it is read-only). To be honest I am strongly considering going back to El Capitan from my Time Machine backup.

What is to be done in this case? Reformat to what? OS Journaled? NTFS? I am using the drive on both Windows and Mac OS.
