[Sussex] New PC, frustration, frustration.

Tue Jun 21 19:57:18 UTC 2011

Wotcha List,

Ok, so I recently posted about how to move data from my old PC to the  
replacement (HO Pavilion p6799). As far as I can tell, it's a 64 bit  
machine, so I've installed Ubuntu 11.04 64bit.

Generally it seems to be working fine.

The biggest hassle was moving the data, as already mentioned. This was done  
by a mishmash of dropbox, DVD's and application specific answers  
like "xmarks" for firefox. Of the various challenges, re-installing my  
music has proved the worst.

Why? Because despite the success of completing the task (well 99%) - which  
did take an inordinate amount of time (my music is all in FLAC format, the  
file sizes and general amount of music to copy back to the new machine), I  
found a little problem that I can't, as yet, solve.

On one DVD (relating to the album/CD it was ripped from), there was an  
error that came up twice. It seems it was to do with excessively long song  
titles.

Ok thinks me, I can just re-rip the two tracks and I should be able to edit  
the song titles - No such luck.

While the system found and allowed me to copy the music DVD's back to the  
hard drive (well my /home/music), the machine doesn't seem to see the  
actual drive with an audio CD in it.

I've had a bit of a google, and as far as I can see, the system seems to  
see the drive, but the applications can't. I've looked at the /etc/fstab  
and there's no mention of it there.

Trying the "sudo lshw -C disk" command gives me this

"*-cdrom

and the "sudo hdparm -I /dev/dvd" and "sudo hdparm -I /dev/cdrom" give me :-

respectively.

Plus "dmesg | grep -i dvd" then tells me this

"[ 2.862292] ata3.00: ATAPI: hp DVD A DH16ABLH, 3HD9, max UDMA/100
[ 2.865295] scsi 2:0:0:0: CD-ROM hp DVD A DH16ABLH 3HD9 PQ: 0 ANSI: 5
[ 2.868894] sr0: scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2  
cdda tray"

Another command, "ls -al /dev/sr*" gives me this

"brw-rw----+ 1 root cdrom 11, 0 2011-06-21 20:17 /dev/sr0"

But I don't know what it all means (anyone can find commands on various  
forums etc and input them, but when it comes to de-cyphering them, it's a  
rather different matter) other than the system seems to see the the drive.  
So, I still have no idea how to get the damn device to detect discs when  
they're put in the drive.

Can anyone point me in the right direction please ?

regards
