[Galaxy S III Q&A, Help & Troubleshooting] ctrlbru:
As it seems I cannot post in the proper developer post (beign a developer myself... but ok I understand the limitation), and since Philz3759 cannot receive PMs (and I understand this too, being him so popular), I'm posting here just in case someone can report him or maybe already has a solution.

I use Philz Touch recovery for my nandroid on external sd like everyday, since ages, no issues. Now to update to the latest temasek CM11 I had to upgrade from 5.something to 6.12.8 and I'm suddenly unable to backup to external sd.

Essential log:

>> Free space: 12010Mb (40%)
>> Needed space: 3439Mb
mkdir: can't create directory '/storage/sdcard1/clockworkmod/backup/2014-02-10.17.23.28_11-20140206-UNOFFICIAL-temasek-': Operation not permitted

Obvious things: the sd works, it's NTFS (supported) and I already used it many many times with the previous recovery version. When OS is loaded I can r/w etc and I can create a folder like the one the recovery is trying to create. When in recovery, Aroma FM cannot create a file or folder there, and backup fails as it tries to create the backup directory.

As a side note, I also installed a different kernel than before (boeffla instead of plain cm11), so this may be interfering with NTFS access.

Long log follows (I had to cleanup some links because of the 10 posts limitation.....)
