LG DVD drive & Acer's combo (DVD + CD writer) error!



Hi everybody,
I have the following problem: I have simultaneous:

  • read errors with my LG DVD drive (on my desktop) when I try to make a back-up copy of a CD (am image): CloneCD remain at 10% forever when he read the disc :rolleyes:
  • write errors when I try to burn something on my combo Slimtype (on laptop) with Nero or CloneCD, exactly by 30%!!!
    All these drives were working perfect until that!
    Is there a possibility (software) to check the drives?
    Please help me with an advice.
    Thank you in advance.
