Hi,
I too had the same problem with a 32g Ultra Card in an S3.
Was taking videos on holiday,suddenly the phone told me that Camera has stopped working.Phone froze at this point. Had to re-boot device and then notifacation came up telling me that SD Card was Blank…(a lot of data on it)
Returned home and tried in vain to get card to connect with PC…no way.Tried to formatt within phone…Nothing.
Contacted Sandisc…they gave me a link to a firm that recovers data…£171/210 charge If they can get any data off it.In the end, just posted the faulty card of to Sandisc for a replacement card.
According to Sandisc this problem with cards and Samsung devices has now been fixed…
Cheers
