I've got a Hewlett Packard CD-Writer plus 9100 series, and I've recently started using DirectCD (CD-Writable software), to turn all my CD-RW into extra hard drive space. Unfortunately a couple of times of gone to use these CD's but certain programs, usually whole directories have vanished! Does anybody know what might be happening? I wasn't sure if this was the correct forum but I was told you guys are that brilliantly, you'd be able to help me (sic). I've read that part of the process of writing to CD-RW involves the use of magnetic particles, could I have erased part of my data. Thanks for all help, and I hope to here from you.
