This happens all the time - but for example - yesterday I took 350 photos, when importing them directly from the CF card with Lightroom, seven of them were corrupt.
However, if I manually copy the files to the HD and then import into lightroom - no corruption.
I have used a hex comparison tool to compare the good and bad files and sure enough there are a couple of picked bits here and there.
I'm a bit confused. I have some basic questions...
How can Lightroom introduce corruption at this stage? Seems implausible?
If there was a corruption - why on earth wasn't it detected at transfer time? Surely there is some sort of basic checking, CRC at a minimum - yes/no?
