Bug#926717: linux-image-4.19.0-4-amd64: Size of DVD in external drive not recognised properly



Package: src:linux
Version: 4.19.28-2
Severity: normal

Dear Maintainer,

I recently got an external (USB) DVD drive, an LG GP57EB40. It seems to
works well with CDs. For DVDs, however, the capacity is wrong/too small
and the sector size is reported to be 512 Bytes. This problem does *not*
occur with another USB DVD drive (Panasonic/Matshita) or when using the
the LG drive under Windows. This should rule out HW defects of the drive
or the DVDs. More details below.

A very similar bug report was filed in Ubuntu
(https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/42023 comment 30)
but remained unresolved. JFTR: I do not have 'udftools' installed.


Below are all details I figured out up to this point, a few logs I
deem related, and the information collected by 'reportbug'. If any
additional info is required/useful, I'll try to provide it (though it
might take some time). I'd also appreciate suggestions of how to
further investigate this problem.

Best regards, Jan



Details
~~~~~~~
Connecting the LG drive to the laptop (direct connection, no hubs
involved) and inserting a DVD will report that DVD's total size to
be about 1GiB. This is also the amount of data after which 'dd' fails
to read from the drive. In 'dmesg' errors like the following appear

[900560.169677] attempt to access beyond end of device
[900560.169680] sr0: rw=0, want=9118156, limit=2097151

Even before that failure I see unhealthy messages 

[899894.336095] print_req_error: I/O error, dev sr0, sector 2096864
[899894.336101] Buffer I/O error on dev sr0, logical block 2096864, async page read
[899894.336128] sr 6:0:0:0: [sr0] tag#0 unaligned transfer


'blockdev --report' yields

RO    RA   SSZ   BSZ   StartSec            Size   Device
rw   256   512   512          0      1073741312   /dev/sr0

Note the wrong sector wize which should be 2048 for CD/DVD. Those
numbers remain the same for all DVDs I tried (all larger than 1Gib).
The very same DVD on the same machine but in the Panasonic drive works
and gives this output instead

RO    RA   SSZ   BSZ   StartSec            Size   Device
rw   256  2048  4096          0      3978297344   /dev/sr1


The LG drive works well so far for CDs. But if I insert a CD first, use it
and replace it with a DVD, the output of 'blockdev' still shows the
values it had for the CD and the “available size” of the DVD is limited to
that of the CD.
