Several times now I've imported images into LR4 from my External HD and and a few the files are corrupted. (See attached image)
I realize that LR is not suppose to do anything to the files on the disk when importing... but I've checked the RAW images from back-ups and they are not corrupted prior to import into LR. AFTER import into LR the actual file (on the external HD) IS corrupted in both LR and then on the External HD.
My workflow has been to copy files from my CF Card to the External HD (Western Digital 3 TB) ino the appropriate file... then go to LR4 and import.
Can anyone suggest what the problem is? I replaced the Card Reader... same problem occurs. I've checked numerous RAW files in Bridge... none are shown as corrupted (prior to LR4 import)
