So I just bought a MicroSD card today from Canada Computers (So I don't need to worry about the fake card bs) as a replacement for my old one which would apparently get "corrupted" after a few weeks to a few months of it being used as internal shared storage but would last forever as an external storage, which is a weird enough situation as is. Anyways, this SD card that I got is almost way worse, when I put it in my phone and formatted it as internal and connected a usb cable to transfer my music and photos back on, it would not let me and it would not even show up in the file explorer although normally it would say Internal shared storage, it just said internal storage and it just said the 10 gigs I had for storage. When I took it out and put it into an sd card reader, it said it was a usb, which is normal but would still act the same, but another usb, called usb G: appeared saying it was corrupted and that I needed to format it, which I didnt, I went back to the sd card and tried to copy some music but it would not let me as it would say "error 0x80070057 invalid parameters", but when I formatted the card back to external, I had no problem copying music, etc onto the card, I then formatted it back to internal through my phone and then formatted the card from my computer through the sd card reader and then when I put it back into my phone, it says all 32 gigs out of 32 gigs are used only by the system, but I can format it back to external and itll say only 65 kb are used, but I can then format back to internal from my phone and it will still say all 32 gigs are being used by system, I will go tomorrow back to canada computers and see if they can be of any help and if they will give me a replacement card or fix it.
