Re: DVD-RW writes but doesn't read

[Samuel Torres]

Just a few days ago I installed a brand new OEM AOpen DUW1608/ARR. At 
times while mounting DVDs the drive would lose files between ls's, or 
get I/O errors while ls'ing. I also noticed the same errors you posted 
below. I might have stumbled across a solution to this problem. In my 
BIOS I changed all of the AUTO's in the CD/DVD drive properties and set 
them to CD/DVD (drive type), PIO-4 (PIO MODE), and DMA-4 (DMA MODE). 
This change had an apparent effect which no longer produces such reading 
errors, at least from the 4 reading tests (2 DVD and 2 CD). The 2 DVD 
reads were done with vobcopy, and the CD tests were done with cdrdao, 
and md5sum (checking the Ubuntu files with the CD with the provided 
md5sum.txt, from within the CD, in the DVD drive).

Hope it works.

Every DVD and CD is perfect. I've burnt about 20.

Re: DVD-RW writes but doesn't read

[surya]

Even I had the same problem - It wasnt reading the written dvd-r/rw .But then
Once I tried closing the session after a burn(not closing disk) .
Then it started to show up the files .This is on 2.6.9 . But now the dvd drive
stopped reading cd's anymore ;-(

Re: DVD-RW writes but doesn't read

[Norbert van Nobelen]

Did you try one of the disks you have written with it in another dvdplayer 
yet?

If the written dvds really work, then it is clearly a miracle (-:. The first 
thing the drive does, is a read action to see if it has an empty disc or 
something like multisession. If the drive reading is so terrible, that action 
should fail most of the time too.

DVD-RW writes but doesn't read

[Con Kolivas]

Hi Jens et al

I have a laptop DVD-RW that is working fine when burning but has endless 
streams of errors with any kernel I try when trying to read anything (cd/dvd 
audio/video/data).

hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50
ide: failed opcode was 100
end_request: I/O error, dev hdc, sector 571832
Buffer I/O error on device hdc, logical block 71479

If I'm persistent I can read the data off the drive but I'll probably 
kill the drive in the process. It doesn't matter what iosched I use but I 
use cfq by default. I've tried disabling dma and so on without success. Any 
ideas?
