Yes, but spath is claiming that EAC uses the same command as PlexTools in a thread on HA (http://www.hydrogenaudio.org/forums/...wtopic=41028#). So, if EAC fails, shouldn't PlexTools fail as well?

I know (and believe) what spath wrote ... I guess it rather is a matter of implementation.

And btw ... I have seen Plextools fail on damaged CD's as well ... something like 0 errors reported (or successful correction of all existing errors) and non-matching T&C with a second extraction run ...

I have been using it for about a week now and have probably done about 50-100 CDs with the switch on. I use T&C and AccurateRip as well. EAC has been reporting errors consistent with T&C and AR. I have 4 Plextor Drives, Premium, 712A, 4824, and a 5224. It has worked well with all of them. Running XP Pro with SP2

I'm realy sorry for asking it but I'm not completely understand the -usefua switch. I have PX-716A. EAC detects the support for Accurate Stream and C2. Also it reports that drive caches data, so I have all 3 options turned on in Drive settings. It's clear and ripping going on. Now I start EAC with -usefua switch and what now? Should I turn off "Drive caches audio data" option to get what? Or should I leave it and again to get what? How this option effects precise of the ripping?
Thanks in advance for your answers!

Yes, you should now disable the "Drive caches audio data". You can recheck and see if EAC still detects that the drive chaches audio but this feature is known to be someone buggy so Im not sure I trust its reliability. I use Test&Copy (shift-F6) with this method - VERY fast, accurate and secure.

I recently purchased a disc which is written in a format incompatible with the Red Book standard: Beth Ortons's Comfort of Strangers (EMI). I ripped it for fair use with a Squeezebox, a device which streams digital audio to my home stereo system.

Using a PX716A and the -usefua switch and 'Drive caches audio data' unchecked, the disc ripped at a speed of 7.5X. A test rip without -usefua and 'Drive caches audio data' checked ripped at 1.9X.

The attached log file indicates CRC matches for all tracks. Additionally, foobar2000's bit comparison plugin reports no differences between files.

The results are encouraging. I conclude that -usefua shows promise for extraction of audio data from such error-prone media.

windowshade, may I suggest you turn on over-read into lead in/out and turn off fill missing offeset sample with silence. Your plex drive is perfectly capable of doing this and getting all the data.

Does your drive report "caching audio" when you test it with the -usefua switch? Mine does, so that worries me a bit. So far though, the wav's test out fine.

If the drive test gives "caching: Yes" the -usefua switch doesn't work with your drive. You may repeat the test using a different CD, but if it still says "Yes" you should not disable the "drive caches audio data" box and forget about using -usefua.

OK, that clears it up. Thanks.

FWIW, I have a Plextor 716A DVD/CD writer.

Please also note that doing the EAC drive test isn't enough for determining if the -usefua switch is actually working or not...

I have a Plextor PX-755A and the -usefua option seems to work fine. I didn't recognise any differences.
The drive test within of EAC tells me that the drive is caching audio data.

The speed was increased by 50-150% (depending on the disc).

Added:
What I wrote is wrong. After many tests I found an Audio CD which is causing problems with 'Drive caches audio data' switched off. I used the test and copy function. EAC said, that the ripping was okay (both times the same checksum). But AccurateRip said, that 2 tracks were copied incorrect.
So I made the test again with/without C2 and with/without the Audio Cache checkbox checked.

Result:
Only when I checked 'Drive caches audio data' ON I got the awaited results for all tracks.

This means that the -usefua code may NOT be working fine. If the command is working EAC should report that the drive is NOT caching audio data. But EACs detection is unreliable....

I tested this -uesfua option on a HL-DT-ST GDR-8163B drive, which is supposed to have a cache according to http://www.daefeatures.co.uk/ and the internal test routine of EAC.

So with this option enabled I tested a bad disc, which is also copy protected and reports many C2-Errors (the red bar is getting filled completly with dots), but the result were 2 wave-files, which are exactly the same!
According to that the drive might not cache audio-data after all (firmware 0L23), OR the option is working with drives apart from Plextor.

PS: I tested the drive with the daequality-software from exactaudiocopy.de using the self-created test-cd as described on the website and my drive gets a 100% C2-accuracy, so the errors reported from the cd must be correct.
