How do I stop files from disappearing or returning to my SD card?

Any file I delete on my rooted Android phone’s SD card will return upon reboot, and any file I save will disappear upon reboot.

I’ve tried deleting and formatting the card on the computer and it shows it as being empty but as soon as I put it back in the phone all the files are back.

Not sure if I’ve screwed up the permissions or what. I can flash the one Nandroid backup that was still on my card but it does no good. My phone is rooted and I do have TWRP recovery installed.

      how about to check on another computer?

      Click Start and then Run. Type cmd and then click OK. Type the following:
      chkdsk [sd card drive letter] /r
      this will Scan for and attempt Recovery of bad sectorsor
      chkdsk [sd card drive letter] /f
      this will Automatically Fix file system errors on the disk
      http://ss64.com/nt/chkdsk.html
      there is possibility that files will be deleted or turn to.chk format

    Scan it for viruses, take out the mem card put it in mem card reader , open it in your computer and scan it properly !!!

    If then also the problem stays then maybe your card is faulty !
