Re: burner disappears after update kernel

Sadly enough, dmesg says:

ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
hdd: _NEC DVD_RW ND-2500A, ATAPI CD/DVD-ROM drive


The above indicates hdc is a DVDROM and not a DVD burner

but cdrecord tells:
scsidev: '/dev/hdd'
devname: '/dev/hdd'
scsibus: -2 target: -2 lun: -2
Warning: Open by 'devname' is unintentional and not supported.
cdrecord: No such device or address. Cannot open '/dev/hdd'. Cannot open
SCSI driver.

Suggestions are more than welcome...

cdrecord cannot open a dvd-rom device for burning. It also indicates you tried to access /dev/hdd and not hdc.

Is /dev/hdd actually a dvd burner? or did you mean to use hdc?

If hdd is a dvd burner, what does dmesg say about hdd?

As shown by Anard's citation of FC2 releases notes, actually cdrecord
can be invoked this way:

cdrecord dev=/dev/hdd ....

That's the way my own backup BASH script invokes it everyday, and it
works. With FC 1, that script used the usual SCSI syntax (cdrecord
dev=0,1,0...), but when I installed FC 2, it stopped working, so, after
some hacking, it turned back to work using thie first syntax above.

But please note the lines in cdrecord's output about this naming
convention...

Best regards.

You should access the burner with the IDE name convention, e.g.
"/dev/hdd". I understand that now IDE devices, although mapped to SCSI
devices, can be accessed with the usuale IDE naming convention. This
affects not only the kernel, but cdrecord too.


Does cdrecord supports dev=/dev/hdd or so ??  since a cdrecord -scanbus
only shows the first and not both cdrom drives.



Hope it helps.

When I use the updated 2.6.6 kernel (from the original 2.5 FC2 kernel)
cdrecord is unable to find my cd burner (slave on the second IDE
controller)
I tried to add hdc=ide-scsi and hdd=ide-scsi to grub.conf but no
difference

Rebooting with the original 2.5 FC2 kernel solves the problem

Any suggestions ?
