ive got my 64gb memory card running as ux0 but my 4gb sony card doesn't show up as uma0 ,also if I eject the sony 4gb card when I switch on the database updates and even tho the 64gb sd2vita crad is still in it doesn't show up,unless I put the sony 4gb card back in,then it will update database again and show sd2vita 64gb card as ux0 and still sony card is a no show,What have I done ?
