[aclug-L] Re: CD-ROM drive speeds

[Jonathan Hall <jonhall@xxxxxxxxxxxx>]

it is not atypical for a "fast" CD drive to spin up and down constantly when
it's being randomly accessed or playing a 1x CD.  But when I'm running
something like cdparanoia (or cat /dev/scd1 > /devnull), it pulls the data
off the drive as fast as the drive is capable at sustained rates.  There
should never even be an opporitunity for the drive to spin down.
