[GLLUG] SD card error

[Richard Houser]

For making the image, ddrescue is a lot better suited than dd.  Basically,
it does the same thing when everything goes right, but is designed
specifically for when things aren't ideal.  I usually use it for recovering
data of failing hard drives.  For the best performance in the case of error
retries, make sure to match the sector size with the physical media itself.
