As I have not found a business or anyone willing to replace the emmc drive in my 2-in--1 Tablet PC I am very probably going to have to send it from the UK to USA for replacement / repair, under warranty. I am very much in need of advice regarding this unfamiliar and unwelcome action.
For example, if possible should I format the C drive? And before doing this should I backup all or some of it to an external drive first, or is it likely this will copy the faults in the drive?
Secondly, with regard to the imminent Creators update should I try to install this before sending the machine back, or should I try to send it back before the (compulsory) update arrives?
I may well be able to carry out these procedures because I understand (although the machine is not in my hands at present) it is still usable for many activities, despite the faulty drive (emmc, very difficult / costly to replace), which is however causing more than a dozen malfunctions, like being unable to download / update Store apps, or set a PIN code for signing in, or use links in Mail, etc.
I have seen that there are some items on emmc's in this webpage I have not encountered elsewhere which I will read with interest.
