I have a number of old, old CD-ROMs with large AVI and other movie files on them (usually one file per CD).

When I try to copy the files over in finder, it eventually fails with error -36. I assume this is because some sectors on the CD have become faulty.

Is there an error-tolerant way to copy over the files, including the faulty sectors, to see whether the files work anyway (with maybe a few minutes missing)?

    New CD/DVD drive is the least headache - 20 bucks, these days - chances are it's the drive not the disk. btw, movies with bad data will not skip the bad segments, they will just halt, with no way past. – Tetsujin Jul 29 '16 at 19:06
  • @Tetsujin didn't think about that, will try with a different drive! – Pekka Jul 29 '16 at 19:06
  • @Pekka 웃, Before going out a buying a new optical drive, test copy a disc that had issues on your drive, on another drive on a different computer of a friend maybe. If it has the same issues as on yours then it's the disc not the drive. To get past the bad sectors you can use ddrescue or dd either of which should be able to skip the bad sectors as there no sense in copying the bad sectors. See want you can get off the disc that way. – user3439894 Jul 30 '16 at 2:17
