cdparanoia vs EAC

[Fredrik Öberg]

Hi all,
sorry if this has been asked before (I guess it have), but I could not
find any old message in the archives on this topic, so here we go.

I have been using EAC for ripping music as long as I can remember.
When I was on Windows, it was the natural choice. A couple of years
ago I switched to Linux, but I have been using EAC together with wine
since the switch.

The reason for using EAC instead of cdparanoia has been that EAC has
been able to handle drives with caches, while cdparanoia hasn't. Now I
see that there is a new version (since September last year) which seem
to be able to handle drives with caches.

If I understand it correctly, cdparanoia is now able to handle drives
with caches, just like EAC. Is this correct?

I run the cdparanoia -A test on my drive, and it ended up with
something like "Drive tests OK with Paranoia." Does this mean that the
rips done with cdparanoia will be as accurate as the ones done with
EAC?

Thanks in advance

Well, it's more that EAC expects drives can have bigger/different
caches than older Paranoia did.  A few more drives today also offer
command set ways to force media access, as opposed to attempting to
trick the drive into flushing cache via access patterns. But only a
few (and you can't rely on that).

Both EAC and Paranoia will still have the problem where a drive with a
completely different cache strategy can defeat them without either
knowing (thus bundling the new -A tests with cdparanoia that tries to
find these drives).

Old paranoia did have cache-modelling code, but it had become out of
date since the last major update in 1998.  The new code incorporates
behavior modelling for recent drives.

"Handle as many at least as well", I think so.  Again, I bundled the
test mode for a reason :-)  As EAC is closed, none of us really have
any idea what it is doing.

Yes.
