I am copying files from 2 types of old external drives: NTFS and FAT32. While coping a lot of files from the NTFS drive(to a MBP13" '09) it caused my computer to freeze up, and I had to force a shut down via the power button . Anyone else have problems like this copying a large quantity of files? Is there a GB limit you can copy at one time, or maximum number of files? FYI, my MBP locked up while it was "preparing to copy." It was stuck on just over the 40,000th file (was the large number of files the problem?). Any ideas or suggestions? Now, I am copying smaller batches at a time, and so far so good. So was the large copy I originally tried, too large? How many GB and/or files have you successfully copied from an external hard drive? Also, when I get these files to my MBP internal drive(HFS+Journaled), how difficult will it be to copy them and the new files created on the MBP to an NTFS or FAT32 external drive? Does it require special software to do this? Any problems I should be concerned about or precautions I should take regarding file names, sizes, etc? Thanks for reading this, and any thoughts would be appreciated!
