I have a 32GB SDHC card which I'm trying copy some music and pictures to. I have windows formatted the card and copied about 7 GB which was very slow after the first couple GB. I then looked at the copied folders and many of their names were corrupted gibberish (all forms of characters). I ran chkdsk on the SD, and it found many errors and said it corrected them. I then deleted the FOUND.000 folder; tried copying the files back on the SD card. When, I ran CHKDSK it found another set of bad files. Is the SD card no good or do I need to apply another tool to it? I have tried this with two different adapters and on an XP desktop and Windows 7 laptop. There are no errors while copying. Instead of doing a simple copy of a folder I also used FreeFileSync with very similar results.
