idecd: attempt to access beyond end of device

[Sebastian Kemper]

Hello list,

I'm getting these errors trying to mount a burned DVD-R:

Nov  8 12:39:08 section_eight attempt to access beyond end of device
Nov  8 12:39:08 section_eight hdc: rw=0, want=68, limit=4
Nov  8 12:39:08 section_eight isofs_fill_super: bread failed, dev=hdc,
iso_blknum=16, block=1

The drive is a NEC ND-4550A ATAPI. I use idecd and kernel 2.6.18.2.

DVD+R discs mount just fine. There were no errors while burning the
DVD-R. I tried k3b(-0.12.17),
cdrecord(-2.01.01_alpha10/-2.01.01_alpha20) and growisofs-6.1/-7.0. The
drive is flashed with the latest firmware and the manufacturer claims my
16x DVD-R media is supported.

I can actually mount the burned DVD-R in my other DVD-ROM drive (it's a
read-only device, LITE-ON DVD SOHD-16P9SV).

I'm a bit lost because I can't figure out the proper place to report
this bug. I already posted to k3b-user but got no response. If you could
direct me to the proper person to talk to I'd be happy.

Hi Alan,

yes, the same happens with ide-scsi:

mount dvdrw/
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

syslog:

Nov 12 17:41:59 section_eight attempt to access beyond end of device
Nov 12 17:41:59 section_eight sr0: rw=0, want=68, limit=4
Nov 12 17:41:59 section_eight isofs_fill_super: bread failed, dev=sr0,
iso_blknum=16, block=16

Regards
Sebastian

Hello Alan,

no, I don't have EFI partition support.
