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

~~~~~~~
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.

I'm at a loss of ideas what the trigger could be. AFAIK video DVD *are* ordinary data DVDs with some predefined file layout.

The also works with FreeBSD. I only checked in a VM but since the USB device is passed through that should not affect the result. FreeBSD provides the following information when connection the DVD drive
> ugen1.2: <Hitachi-LG Data Storage Inc Portable Super Multi Drive> at usbus1
> umass0 on uhub0
> umass0: <6238--Storage> on usbus1
> umass0: 8070i (ATAPI) over Bulk-Only; quirks = 0x0100
> umass0:2:0: Attached to scbus2
> cd0 at umass-sim0 bus 0 scbus2 target 0 lun 0
> cd0: <HL-DT-ST DVDRAM GP57EB40 PF01> Removable CD-ROM SCSI device
> cd0: 40.000MB/s transfers
> cd0: 3794MB (1942528 2048 byte sectors)
> cd0: quirks=0x10<10_BYTE_ONLY>
These test also lead to another interesting observation: Assigning the drive to a VirtualBox VM (FreeBSD in this case) and then giving it back it to the native Linux, will make it properly recognize the DVD currently in the drive. Unloading and reloading the 'usb-storage' kernel module has a similar effect. I tried the available quirks of the 'usb-storage' module (especially 'US_FL_INITIAL_READ10' looked promising), but to no avail.

> JFTR: I do not have 'udftools' installed.
Is there any mention of pktsetup or pktcdvd in dmesg? Although you don't have
udftools installed, it seems most of the implementation is in the kernel;
udftools's pktsetup is just a userland tool for running modprobe, sending a
couple of ioctls, and printing status.
BTW, thanks for the hint about udftools, it solved my problem if not yours.
BR,

Sorry, forgot to also send the answer to the bug tracker. So here's an updated version:

All symptoms described in this bug report remain and there's no mention of pktsetup or pktcdvd in 'journalctl'
