Hi, I'm having a really strange problem with my DVD drive in my Athlon64 X2 box, in that I'm unable to mount a CDROM because the machine thinks there is a hardware error. The strange thing is, that this failure is dependent upon the mode in which I boot the machine. For example, if I boot my machine with the CD in the drive, the machine reads the disc and boots quite happily from the CD. If I boot the machine without the CD into safe mode, I'm able to manually mount the CD and read it, however if I boot my machine normally I cannot mount the CD and mount reports the following error "mount_cd9660: /dev/acd0: Input/output error". dmesg reports : "Trying to mount root from ufs:/dev/ad12s1a acd0: FAILURE - READ_BIG HARDWARE ERROR asc=0x08 ascq=0x03 error=0 g_vfs_done():acd0[READ(offset=32768, length=2048)]error = 5" In all cases, the same FreeBSD AMD RC1 boot disc is used, so I know the disc is OK. Has anyone else seen this type of problem? Any ideas how to resolve it? Is there any difference between the default boot mode and safe mode that is likely to cause this problem?
