Bug Description
Binary package hint: hdparm
Ubuntu 9.10 32bit.
hdparm v 9.15
I have an optical drive that I use in a media player PC. This drive is connected to the ATA ribbon cable in the system, NOT to a SATA port. When playing audio cd's or video dvd's it is very loud, as it tries to spin up to full speed (52X or whatever).
On previous versions of Ubuntu, I could use hdparm to tune this. It seems when we ditched /dev/hdx for /dev/sdx and /dev/sr0 we lost this capability:
# hdparm -E 1 /dev/dvd
/dev/dvd:
setting cdrom speed to 1
setting dvd streaming speed to 1
dvd speed setting failed: Input/output error
No matter what number I send in, this is the error.
I did about 90 minutes of googling and reading, and I can't find any explanation or hints. There has been suggestion for sdparm, but it doesn't seem to have these parameters.
Thanks

Hi!
This bug affects me. It forces my blu-ray drive 'ASUS BW-16D1HT' to read only at minimum speed. It is extremely annoying as the drive paradoxically writes at X6 (or even faster) speed just fine using cdrecord.
$ hdparm -E /dev/sr0
returns same error as you.
$ eject /dev/sr0 -vx 8
Does nothing.
Kernel is quiet and nothing displayed on the logs.
So when this will be fixed? Now I have to wait for ~20min to read a single 25GBit Bly-ray disk versus burning 25Gbit image in 14mins.
