Why has this only showing as 116gb nof 128gb??

it is because the disk is being messured @ 1024mb per gig and NOT 1000mb per gig, The manufacturer measures a Gigabyte as "1000 megabytes" while the computer measures it as "1024 megabytes." This is also why your "2 GB" hard drive only has ~1.81 GB (Technically "GiB", or "Gibibytes") of space. I hope that helps!

What is the difference between this znd the regular sandisc 128gb sd card and the extreme card? this looks identical in specs to the regular card.

There’s very little in difference, personally if you’re getting the card for the Nintendo Switch I’d say go for the ultra, the extreme has better read and write speeds but because the system has a cap on the read and write you’ll probably see very little in load times (maybe 1 second better with the extreme) The Nintendo branded ones however are exactly like the ultra cards just slightly more optimised for the switch but again not a noticeable amount.

My card stopped working after 3 months and can’t be formatted or recognised. Any advice or customer aftercare you can offer?

Technically you warranty is with Amazon if that’s where you purchased from so contact the returns department. Alternatively search for Sandisk UK and use your Amazon receipt as proof of purchase again if that’s how you purchased it.

Hi, can I add mp3 music files on this card?

Absolutely, but they can only be played back on a device that allows it, the Nintendo switch doesn't play MP3s
