Thx drlucky for reply, and sorry for response taking so long!
I don’t think I wanna take this issue with Sony. Stereo is pretty old, 2008 device
anyway. I bought new Pioneer car stereo 2 years ago and I was surprised that 2013 device
still fails play files in alphabetical order and rather decides to play them in the order they are
present on FAT.
As a result, I dont trust car manufacturers in general to be able to build quality devices, much simpler
solution is to use ‘random’ car stereo as a slave and stream music from mobile device instead.
mp3 cabale players have been in market a decade now and still they manage to sell such rubbish.
My flashdrive is listed as ‘Removable’ (apparently same as fixed?) in diskpart.
