我的光驱好多盘都读不了了

[danielking]

光盘放进去后，dmesg里面很多这样的信息

[ 78.314264] ppdev: user-space parallel port driver
[ 81.233752] end_request: I/O error, dev sr0, sector 4792
[ 81.233757] Buffer I/O error on device sr0, logical block 1198
[ 81.234060] Buffer I/O error on device sr0, logical block 1199

[ 81.349947] Buffer I/O error on device sr0, logical block 1198
[ 81.443488] end_request: I/O error, dev sr0, sector 4796
[ 81.443492] Buffer I/O error on device sr0, logical block 1199

重启到windows和macosx，读盘一点问题没有，还是比较新的光驱
linux还重装过，之前也这样，本以为是系统问题，可重装了以后还是这样

这是怎么回事呢？
