I just plugged in my canon sd memory card and it said the "file or directory is corrupted or unreadable". So I clicked CMD and typed in Chkdsk I: /r and it came up with "Unrecoverable error in folder \DCIM\215__04. Convert folder to file (Y/N)? I typed Y. Then it asked "Convert lost chains to files (Y/N)? I typed Y again. What the hell did I just do... I think what was left of my memory card is lost forever. HELP!
