DVD drive problem

    I've been having DVD drive issues for about 3 days now, and it's confusing me to no end.

    Device: Lite-On DVDRW LH-20A1H ATA

    Basically when I go to install games it will start installing the game normally, and then randomly(I say this because the same game has stopped in several different points over multiple installs) it will get stuck installing a file....and I will hear the drive try and read the same location over and over again.

    This is one of installation error messages I'm receiving:

    C:\Program Files (x86)\Turbine\The Lord of the Rings Online\client_mesh.dat

    An error occurred while trying to copy a file:
    Data error (cyclic redundancy check)

    Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation.


    The confusing part about this is that over the last few days I've installed multiple copies of both Linux, OSX, and the new Windows 7 beta on my computer and all have installed flawlessly...not to mention I wrote the .ISO file onto a disk for Windows 7 beta.

    I'm unsure of the problem and hoping someone here could help me, thanks.

    Hi Blue,

    CRC (Cyclic Redundancy Check) is a check of data transfer correctness. It's a 'parity' check but, much more complicated than an oldfashioned parity check. A CRC is computed on each byte when the file is originally written and is tacked onto the end of the file. Any time that file is copied the CRC is recalculated at the source and compared to the CRC at the end of the original file. It's telling you that the DVD reader is having problems. DVD/CD readers can fail at any point on the disk. Any thing that uses the good part will not have a problem.

    Hope this helps a bit,
    Jim
