Hi... I was copying a huge amount of small midi files (over 64,000, but probably only around 400mb) from one external drive to another. Towards the end copying stopped because I got a finder error on one of the files. I know this stuff would happen sometimes when copying large amounts of data on my pre OSX systems. Generally when that happened, I would copy smaller chunks. This also worked for me in this case and was able to eventually copy everything without error. So my question is this: Why would I get an error in the first place? Is there usually a potential for errors when copying large amounts of data at once? And is this normal behaviour? Thanks in advance!
