A couple of questions, both related to optical drives in GNU/Linux, oddly enough.
Firstly, for some reason, I quite often get errors when installing distributions from CD about corrupt files, yet the media checks are absolutely fine. Any reason for this? The disc will fail consistently, but not necessarily at the same point. On some distributions, typing linux ide=nodma helps, other distributions it doesn't. Is it a case of having drives that don't play nice with GNU/Linux?
Secondly, a particular drive I have doesn't seem to like GNU/Linux very much. Whereas my ancient, seemingly brandless CD drive works smoothly, my DVD rewriter Sony DRU-820A takes ages to read discs - just browsing its root takes a while. Running dmesg provides this:
And so on, again and again. Once again, I have to ask the question: is it a case of having a drive that don't play nice with GNU/Linux? It seems to work in Windows 2000.Code:hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error } hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 3976 Buffer I/O error on device hdc, logical block 994 hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error } hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 } ide: failed opcode was: unknown end_request: I/O error, dev hdc, sector 3980
One final thing - how do you stop the spinning of the disc! Once I put it in, and it is mounted, it just won't stop spinning. If it never gets mounted, it never spins.
Any advice is appreciated.
Mike.
