> That's incorrect. Someone from Lenovo had already posted in the thread saying that it had been escalated.

Well, it had been escalated two months ago and not only there's no fix but not even an explanation why somebody made the deliberate effort to disable standard AHCI mode.

It's not some weird and difficult bug which should take months to track down, but an obvious intentional kludge. All they have to do is say why they did it and either revert this BIOS patch or explain why they can't.

I was talking about the last post, sorry if that wasn't clear. My point was, if other people have the same problem and find the thread, they will not read 19 pages and rather go to the last one to see where's the issue at. And there they will find nothing that answers their question. Lenovo staff could have at least have said "it is a known issue" / "it is a driver issue" / "We have an agreement with Microsoft"... Whatever the reason is.
