Can't format micro sdhc card

[LvStars]

I use an SanDisk 64gb micro sdhc card with my samsung galaxy note 10.1 tablet for a year or so with no problems. Recently I noticed that I can't write files to card, but I can open files that already is there without any problems. So I put it in my laptop and tried format the card, but receive error ''Windows was unable to complete the format'', then I tried to delete all files manually, at first i thought that everything was successful, but after i close folder and reopen it again, all files is still there. I have tried format it with/without quick format and with different formats, but without any success. I even tried different tools like SDFormatter, PartitionGuru and HP USB disk format tool, but they didn't help either. That mean that my card is dead?

What happens when you try to delete the partition?

Same situation like formatting it

Have you tried using another program to try to format the card? For me, if default window reformat doesn't work I usually used a program called Bootice which magically corrects whatever formatting problem I'm having. (Wiping and repartitioning usually required)
