Hi the forum !
i'm french and sorry for my english.....

I have buy TUXERA NTFS v2015.1
When i plug my ZALMAN VE350 HDD case on my MACBOOK 13" late 2009 with OSX El Capitan v 10.11.2 TUXERA return me an error message :
_____________
Tuxera NTFS could not mount /dev/disk4s1
at /Volumes/iPC services_500Go because the following problem occurred:

Aligned I/O enabled.
CBCIO enabled.
Failed to read last sector (976766974): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,
or the partition table is corrupt (partition is smaller than NTFS),
or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/rdisk4s1': Invalid argument
The device '/dev/rdisk4s1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
________________

but when i connect my HDD case on another PC with Windows 7, there work perfectly.
I have try with the TUXERA disk manager, TUXERA found the ZALMAN VE350 interface with partition named : "iPC services_500Go",
i select the partition and i click on "MOUNT". After that i have another error message :
________________
Error while mounting disk disk4s1: Cannot allocate memory
