how to format SanDisk 64 GB

[noelenden]

I have a SanDisk 64 GB ultra micro sd card. Worked fine for a while in my Sony Xperia z2. I could copy and paste files in the card. But recently when I tried to copy some files it copied but after some time it just disappeared. When I tried to delete some older files it just wouldn't delete those files. Tried to format in my laptop but the old files just came back again. The file system is exFat. I want to format this sd card but I don't know how to do it. Help

IF your running Windows on your laptop, simply right click the drive /' drive letter select FORMAT and it will walk you through. Normally you want Fat32 unless the Sony (AndroidOD) is using a special format on it (exFAT as you said), then you may want to use THAT device to instead wipe the drive.
