I noticed that my WD 500GB hdd got couple bad sectors after get message Cyclic Redundancy Check error. I start to backup hdd, but have question.
I move all files from that hdd via network on new 2tb hdd and all files except 2-3 files move on new hdd without problem. Is all other files OK, or maybe I have some corrupted files, it's to many files to do manual check.
If files are on bad sector do I always get message Cyclic Redundancy Check error when try to move or that files can moved and be corrupted on new hdd?

Thanks.

Moving a file implies a read operation on the source. Until the sector becomes reallocated, every time an attempt to read a file which contains a bad sector an error will occur.

Depending on the file type, one or more sectors being lost due to errors could make a file corrupt.
