Can't read from source or disk error

I recently purchased a 32Gb microSDHC card from Verizon. When I try to copy files  via a SDHC reader (tried two different readers BTW), I get a can’t read from source or disk error at which point Win7 will eject the disk.

I tried copying other files from a different location on the hard drive, same error. I reformatted to FAT32, same error, ran scandisk, no errors per Windows. I then tested other flash cards I had, no issue whatsoever copying these exact same files.

Before I exchange or return the card, any idea if this could be of what this is, or is it just a defective card. Also these files were files less than 1Gb, but the total was 14.5GB.
