    I suspect my 8GB Kingston microSDHC card might have some bad blocks.

    Any way to test this on OS X (a la Badblocks, Chkflsh or similar)? I have not found any utilities for this.

    Easiest way might just be to zero the drive/card in Disk Utility. I’ve always found that to be a good test for bad blocks.

    I ended running Chkflsh from my Win 7 machine - just zeroing the drive wouldnt find stuck bits :-s
