Comment 48 for bug 31709

[SOLVED] I had this problem since I changed to Intrepid... I thought it was related to the emulation of sd* (instead of hd*), as hdparm couldn't be used anymore...

My drive is a LG GSA-4167B which is capable of burning DVDs at 8x. It was burning at 1x! (and ubuntu became inoperable during the process).
I solved it with the solution posted by Dimitris:

I now can burn at full speed and be able to use my computer meanwhile.

Thank you Dimitris!!
