I was going to say, I hope its not just using lossy compression. There are
lossless compression systems. flac is what I tend to use.
However not having heard of this device, I'd hope it had some kind of eggs
in one basket fail safe mode for errors on drive and maybe would have two
drives inside it anyhow.
Not all dvD drives are equal. I've noticed that on some cds some drives
slow right down in an attempt to reduce errors. I think they use checksums
to spot errors in each frame of data, so if multiple reading is going on it
could easily go on for ages and sometimes does.

Also how is it looking up the cd db info to label the cds and tracks etc.
many cds seem not to have any cd text or an entry in any of the common cddb
databases or worse, multiple entries each slightly different!
I think ripping cds is not something I bother to do for all my collection
nowadays, although I can no longer read the cases, I have labelled them and
getting up off a sofa to get a cd and play it is good for your circulation!
Nothing to stop people ripping favourite tracks of course and making up a
playlist that way or indeed burning this to another cd if you like. large
ripped collections really only make sense if you are running a disco or a
radio station or have multiple users who use the same media.
Also of course if you really want a totally unlimited collection plenty of
subscription on line services can provide that and if you are always adding
to a collection the subscription route might be more cost effective.

huge CD collection was fed in. At this stage I remoted to him and
PuTTY'd from another machine into the Brennan, primarily to look up the
spec of the internal CD drive (it should be capable of 24x).

I am hopeless with Linux and have never used a Pi. hwinfo and lspci
don't seem to be supported, but dmesg seemed to work. The result
included the following lines. Should I be alarmed?

Looks fine. Some storage is complaining because you turned it off without
a
proper shutdown, but it seems to be surviving.

While the CD drive may be capable of 24x, CD audio has no error
correction.
Therefore if you drive it faster, you may lose audio quality.
Also, 24x is the fastest the drive can do - it's probably a constant
angular
velocity drive, so it'll be 24x on the outside of the CD and much less
towards the inside.

CDs are 74-80 mins, so it's doing about 8x on average. 10 mins each
sounds
about right.

Does the drive whirr for the whole time? If not, it's possible it's also
spending time encoding the audio.
