SD Card Not Recognized

#22
Unfortunately this SD Card problem pops up a lot with Cherry / Bay Trail Atom CPU’s. Installing the Windows 8.1 sdbus.sys driver works but then r/w speed is rather slow. I have several PC’s where the SD Card stops working suddenly without any SW or OS changes. I investigated and I am convinced this is the CHT52 bug in the latest Intel Z8000 specification update. Thus a hardware problem. Point is that Intel also mentions that LPC may stop working. Yikes, then the whole system dies. No solution, better not buy any PC’s with this CPU. Can Minix support reflect on this?

John, this is a forum. Which means information sharing. I guess a number of people here, myself included, would benefit from you sharing information here, instead of via PM.

Thus; what is Minix take on many users experiencing SD card problems? See my post above... I am convinced this is an Intel hardware bug. Do you have more information?

This issue affects a very small % of users, for those users we ask them to PM or email us and we can then assist fulfilling the warranty policy. I think customers would prefer to keep their personal details confidential rather than sharing on the forum.

Ofcourse. You are not discussing warranty claims and such here. But if there is an SD Card issue then it would be nice to discuss that here. I have two Z83-4 Pro’s here and several other Z8300 based micro PC’s. All of these experience SD Card problems after several months of constant use. That is exactly the HW bug that Intel mentions in heir specification update for the Atom Z8000 series. That issue needs to be discussed and it would help to hear Minix’ opinion on this.

Installing the Windows 8.1 sdcard.sys driver works but speed is impacted, maximum is 10 Mbit r/w with this driver.
