error code -36, large files on DVD
I have some commercial DVDs that contain large mov files (between 900MB and 1.5GB each). These are royalty free visual effects and it is 100% legal to copy these files to my hard drive...in fact the company recommends it.
Every time I set it up to copy from the DVD to my internal hard drive (just to clarify that I'm importing the files, not trying to burn to DVD), it will get part way through and give me this error: "The Finder cannot complete the operation because some data in "file_name" could not be read or written. (Error code -36)." Finder then hangs and must be relaunched.
It seems that the disc will start off fine, spinning quite fast, but after a while the spinning slows, then stops altogether. Every time I try it stops at different spots in the copy. I have tried deleting the Finder preferences, restarting the computer, contacting the company to see if there's a copy-protection issue, and copying from the disc to a different hard drive (I have 4 internal drives). I have tried the discs on a MacBook and was able to copy one of the discs, but had the same error code with a different disc.
I have copied from discs that have smaller files and those seem to be fine. Even if I try just copying one file at a time rather than the whole disc, I still get the same error. There are 26 DVDs, so copying one file at a time would take forever anyways. I've tried a lot of them, with the same results.
I know this is an I/O error, but why is it only happening on discs with large files? I'm trying not to have to drive all the way to the Apple Store to have them look at it, is there any way to run a hardware test on the optical drive itself and see if it's having issues? Does Finder just not like the file sizes? Any help would be greatly appreciated.
