Hi JoeBJ,
Thanks for interesting me.
I just received the cable this morning and tested but didn't work.
I tried other ssds including old Mtron SSDs with original and new cables, and they worked well but intel's.
Mac mini never recognized X-25M at all.
So, I gave up at this time and I put old Mtron SSD into Mac mini, and it works fine so far.
If you get a solution by chance, please let me know.
