I had 7.3 running with an HP9100 CDR-RW as slave on hdd and added a Plextor PX320A (DVD w/CDR-RW) as master on hdg. HP9100 was/is set as: /dev/cdrom /dev/sr0 (/dev/hdd) /dev/cdrecorder /dev/sr0 PX320A is set as: /dev/dvd /dev/sr1 (/dev/hdg) /dev/cdrecorder1 /dev/sr1 Using XCDRoast and/or KonCD I consistently make coasters trying to write to the Plextor drive. I do not think that I have ever made a good disk with R or RW media on the Plextor drive but very seldom fail to make a good disk on the HP drive. Reading is not a problem with the Plextor drive for CD's or DVD's. Do I have a configuration problem (hwinfo below) or a defective drive? hwinfo shows (included all disk drives)_: 27: IDE 00.0: 10600 Disk [Created at ide.59] Unique ID: nBbg.W5teKzg0rCE Hardware Class: disk Model: "WDC WD1000BB-00CAA1" Device: "WDC WD1000BB-00CAA1" Driver: "ide-disk" Device File: /dev/hda Geometry (Physical): CHS 47885/16/255 Geometry (Logical): CHS 12161/255/63 Size: 195371568 sectors a 512 bytes Cache: 2048 kb Config Status: cfg=new, avail=yes, crit=no 28: IDE 01.0: 10603 Floppy Disk [Created at ide.59] Unique ID: ENrk.UBgWX1QwqJ1 Hardware Class: floppy Model: "LS-120 VER5 00 UHD Floppy" Device: "LS-120 VER5 00 UHD Floppy" Driver: "ide-floppy" Device File: /dev/hdb Geometry (Physical): CHS 39560/16/63 Geometry (Logical): CHS 80/2/18 Size: 2880 sectors a 512 bytes Config Status: cfg=new, avail=yes, crit=no 29: IDE 02.0: 10600 Disk [Created at ide.59] Unique ID: hY5p.RZvxDfpN8hE Hardware Class: disk Model: "IBM-DJNA-352030" Device: "IBM-DJNA-352030" Driver: "ide-disk" Device File: /dev/hdc Geometry (Physical): CHS 39560/16/63 Geometry (Logical): CHS 39560/16/63 Size: 39876480 sectors a 512 bytes Cache: 1966 kb Config Status: cfg=new, avail=yes, crit=no 31: IDE 04.0: 10600 Disk [Created at ide.59] Unique ID: bvbx.lMo3zCuIuw6 Hardware Class: disk Model: "WDC WD1000BB-00CAA0" Device: "WDC WD1000BB-00CAA0" Driver: "ide-disk" Device File: /dev/hde Geometry (Physical): CHS 193821/16/63 Geometry (Logical): CHS 12161/255/63 Size: 195371568 sectors a 512 bytes Cache: 2048 kb Config Status: cfg=new, avail=yes, crit=no 33: SCSI 00.0: 10602 CD-ROM [Created at scsi.230] Unique ID: zyP1.GqskkRgFDVE Hardware Class: cdrom Model: "HP PLEXTOR CD-R PX-320A" Vendor: "HP" Device: "PLEXTOR CD-R PX-320A" Revision: "1.0a" Driver: "ide-scsi" Device File: /dev/sr0 Drive status: no medium Config Status: cfg=new, avail=yes, crit=no Drive Speed: 32 34: SCSI 01.0: 10602 CD-ROM (DVD) [Created at scsi.230] Unique ID: Q8g5.pvVjXVbZt60 Hardware Class: cdrom Model: "PLEXTOR CD-R PX-320A" Vendor: "PLEXTOR" Device: "CD-R PX-320A" Revision: "1.01" Driver: "ide-scsi" Device File: /dev/sr1 Drive status: no medium Config Status: cfg=new, avail=yes, crit=no Drive Speed: 40 42: SCSI 00.0: 10602 CD-ROM [Created at manual.193] Unique ID: zyP1.mEbcFuMS_OF Hardware Class: cdrom Model: "HP PLEXTOR CD-R PX-320A" Vendor: "HP" Device: "PLEXTOR CD-R PX-320A" Revision: "1.01" Serial ID: "024460" Device File: /dev/sr0 Drive status: no medium Config Status: cfg=new, avail=no, crit=no hdparms: /dev/hda: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 12161/255/63, sectors = 195371568, start = 0 /dev/hdc: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 39560/16/63, sectors = 39876480, start = 0 /dev/hde: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 12161/255/63, sectors = 195371568, start = 0 -- Patrick Shanahan Registered Linux User #207535 @ http://counter.li.org
