I did the tests on 2.6.18 in runlevel 1 with only udevd running to make sure no other program is sending any commands to the drive. I am suspicious about the LG hardware as well so i hooked it to the friendly windows pc in the neighborhood but it works quite well there. The SATA port the LG drive is connected to, was previously occupied by a maxtor harddrive and did it's work without troubles. Does anybody know a possible meaning of the byte sequence 2a 00 00 00 00 80 00 00 40 00 00 00 00 80 00 00 in the context of scsi dvd writing Regards Gerold On Thursday 28 February 2008 08:30:44 Mike Galbraith wrote: >On Mon, 2008-02-25 at 20:05 +0100, Gerold Jury wrote: >> Hello, > >Hi, > >> I have two DVD drives, one connected to the SATA port (LG) the other to >> the IDE port (PHILIPS) of a via chipset. >> They are driven by VIA SATA support (SATA_VIA) and VIA PATA support >> (PATA_VIA). >> >> When I write an iso image to the drive on the SATA port /dev/sr0 it has >> some extra bytes on disk which make the disk unreadable. >> Writing to the IDE drive /dev/sr1 works well. > >I take it kernels < 2.6.23 are known to be functional?

I've tried to reproduce the problem here but failed. Can you please try the test with the file generated with the attached program? "genseqfile 524288 > testfile" will give you 1 meg testfile and it will give us better idea how the data is getting corrupted.

Can you guys please add yourselves to bz#10743? http://bugzilla.kernel.org/show_bug.cgi?id=10743 Please test 2.6.28-rc5 as it contains sata_via changes (TF access needed specific workaround) and see whether the problem is fixed and report on bz. Thanks a lot. Let's get this thing solved. -- tejun ^ permalink raw reply [flat|nested] 11+ messages in thread
