I read that article you linked, but it's not helping me at this time.
Actually, I have several ssds from various manufactures and all other ssds were well attached but Intel. Anyway, I'm waiting for hdd cable for dual drives of mac mini, so will test again once I receive that cable.
I have similar problem, I tried update the Firmware of X-25M, but my Mac Mini still cannot work, what about you? The new cable can work?
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.
