#23

Spath, I was wondering if you were aware about this thread on the SPTD support forum: http://forum.duplexsecure.com/showthread.php?t=280


#24

That’s a very long and entertaining talk, but reality is
much simpler : SPTD breaks FUA, as reported by cachex
and as experienced by every CD ripper which supports FUA,
see http://www.hydrogenaudio.org/forums/index.php?showtopic=54678


#25

That is actually my test at the bottom and I’ve even posted it on the SPTD forum for the new beta. Hopefully something will be worked out where FUA and SPTD can coexist, lol


#26

Many thanks Spath, a very useful tool. And it seems that both of my Lite-On made drives support FUA.

I have Lite-On SOHR-5239V and Sony DW-G120 drives and I when I tried dBpowerAMP 12.1 Reference it said that FUA was working with both drives. I then tried Cache Explorer a number of times and the Sony DW-G120 scores 5/5 every time for the FUA test. The Lite-On SOHR-5239V score varies between 5/5 and 0/5, but is usually 3/5 or better.

I tried dBpowerAMP Reference with about 30 discs (with C2 error support ON, maximum re-reads 700, interpolate OFF). These were ex-library audio books so all of the discs were scratched and some were badly damaged (not just scratches but also holes in the reflective layer), and were not factory pressed CDs but duplicated CDR discs.

Everything seems to be working fine and errors are being corrected (that is the copy in Secure mode with FUA on sounds fine, the same disc in Burst mode has some sound problems). In a few cases the extracted audio did still have some errors that were not successfully corrected but having FUA on or off did not make any difference. The imporvement in speed that using FUA gives is huge, for example one disc with some errors to correct took 10 minutes with FUA on and 2 hours with FUA off.

I have only just started to try Exact Audio Copy (0.99) with -usefua and so far the result looks promising.

Hi,

I seem to have an issue with Cache Explorer. Values are all over the map...

  Hi,

  I tried a similar drive (same model) on another computer (single P4 2.6 GHz - WinXP). This time, I got very different results...

The read cached on my Plextor drive wasn’t being detected by dbPoweramp, so I wound up here. These are the results of running cachex on a PX-800A

Is my computer screwed up? I did buy a lower end ASUS motherboard (A8V-XE) because I wanted something that still worked with the same CPU and RAM. It has behaved oddly at times.

While I am at this, is Plextor still the best brand of CD burner? I’ve read that they have started doing some odd things with the instruction sets of their newer drives so that they will only work correctly with Plextor Utilities. My Plextor does not work with their new utilities, and isn’t even listed in their support section. Maybe it was a defective model.


#30

how are people getting logs of the report or is everyone manually re-typing the findings?


#31

[QUOTE=EliC;2435367]how are people getting logs of the report or is everyone manually re-typing the findings?[/QUOTE]

for those, like me, that don’t know you can put

>results.txt

at the end of your command line to output to a txt file called results (you can name it whatever you want).


#32

Hi Spath … thank you very much for the cachex tool! I used it and it worked very well. :slight_smile:

On the other hand my anti-virus program threw a false positive on both the exe and the zip file. It appears that cachex.exe is a “compressed executable”/is “runtime packed.” Unfortunately, from what I’ve read on the net 90+% of malware/viruses also are runtime packed. This can lead to AV false positives. Isn’t the exe pretty darned small anyway?

Another false positive is at the URL below.

http://forums.comodo.com/empty-t46633.0.html

You have provided us with an excellent tool and I thank you very much for it! My suggestion is that if you ever rebuild the tool that maybe you might not want to make the exe runtime packed.


#33

Hi,

First, an anti-virus which assumes that anything yoda-packed is malicious sucks, and I would suggest for your own good to get something better (like G-Data). Second, I’m far away from drives and firmwares these days so I can’t be bothered to read, recompile or improve my (quite lame) code. If you feel like doing anything with it I’ve attached it to this post, but surely there must be much better tools available these days.

[QUOTE=spath;2522328]Hi,

regards,
–spath[/QUOTE]

Not as lame as the cheap junk from China that we have to use these days. I was thinking that maybe cachex and dbPoweramp just weren’t up to date since their cache detectors didn’t detect any cache with some newer Plextor and Lite-On models. Then when Teac came out with their “industrial grade” DVD burner, lo and behold, nontrivial results were obtained with both pieces of software. There’s no point in improving the CDEX since it does a fine job of finding the drives that don’t suck. Perhaps if there were some fine distinctions to be made in the quality of modern disk drives, it would be worth the effort. I also now have a Plexwriter Premium 2 for reference

#36

many thanks for the tool :slight_smile:


#38

I have also the problem with windows 7 64 Bit and cachex -> Are there some tips to get it working ?


#39

On other question: is there another tool out for testimg the cache ?


#40

I, too, would like to get this working on Win7 64-bit.


#42

Sorry for excavating this old thread but I was recently searching for cache explorer and I could not find it anywhere in the net, until i have taken notice of this thread.
I have am not familiar with compiling C++ source code or any kind of programming but somehow I managed to compile the source code SPath left us with.
I hope I am not violating any right by uploading the compiled exe binary here.
I was just thinking it might help some people, that are desperately searching for this little masterpiece of software.

Anyways I uploaded the binary in my dropbox to improve long.term availibility.
Here the link to download the latest version which is
Spath’s Cache Explorer 0.9:

Enjoy
