 Posted: Wed Dec 19, 2007 1:46 am Post subject: Riddle Me This: IDE Optical Drives Recognized as SCSI |
 |
|
So I've been pounding away at the issue of my optical drives not being recognized, unless I pass "all-generic-ide" along to my kernel. I've got one of those pesky Marvell IDE controllers on my motherboard... 88SE6101, single port PATA133.
After playing around with the dmesg output and some kernel drivers, I discovered that the pata_marvell driver would see my optical drives perfectly fine... but they wouldn't show up under /dev. I also noticed a bit about them being recognized as SCSI drives. So I compiled SCSI CDROM support in. Sure enough, now they're listed under /dev.
Pertinent dmesg snippet:
| Code: | scsi6 : pata_marvell
scsi7 : pata_marvell
ata7: PATA max UDMA/100 cmd 0x00012018 ctl 0x00012026 bmdma 0x00012000 irq 17

K3B refuses to burn CDs, however, so I'm going to assume I need to add some sort of SCSI CDRW support in the kernel. I'm a little confused about why the drives are being recognized as SCSI drives, however... I mean, they're PATA drives, and the two shouldn't have anything to do with each other, right?  |

The "new" pata/sata drivers all emulate scsi controllers, if for no other reason than to use a common interface.
It seems there's no "old" ATA driver for marvell controllers, so you may be stuck with that option.
Make sure under SCSI that you have "<*> SCSI generic support" enabled - I think this might be necessary for SCSI CD burning. |

| With the "new" ata drivers, ide disks show up as /dev/sd* too (with the sata drives). A bit off-putting at first. |

Gotcha. I was kinda confused, since about the same time this started changing over, I switched to a new system. The SATA drive shows up as sd*; the IDE drive connected to an old Ultra133 controller card still shows up as hd*. Now, the optical drives are just throwing me for a loop.
In my naivety, I wish that they went to a "Common Interface" rather than bouncing back and forth between sd and hd. It sure sounds better, at least.
As a side note, the K3b issue was separate... https://forums.gentoo.org/viewtopic-t-588200.html fixed it for me. |

| Ubuntu also thinks IDE drives are SCSI. ("Sexy" pun not intended!) |

You know... I'm never gonna be able to pronounce SCSI "Skawsee" again  |
