would it be possible to make an elf..

that can check the laser for dre's ? like it would show a screen reading the disc then count the number of good/failed bits kinda like nero does on the pc?

Wow, that would be a huge time saver for me. My current method of testing laser strength relies on lots of time, swapping, listening and cog adjusting.

I only know about the tool "Test-Lens" for PS2.
If I find it quickly, I upload it (if allowed).

Edit: Attached. Not sure, if it is the right ELF.

hmm now if i could just read what it said lol

**urbigbro** · 11-07-2008,11:38 PM

Here is roughly what it means. Translated by babel fish and my limited Spanish knowledge.
*Note you must use the "change disc" command before inserting a disc, even if it was already in the PS2 before the app was loaded. Otherwise the tests won't run.

cambiar Disco = change disc
lectura secuencial = sequential reading
lectura alterna = alternating reading
lectura zig-zag 16 etapas = 16 stage zig-zag reading
lectura jump de 2 etapas = 2 stage jump reading
lectura jump2 de 2 etapas = 2 stage jump2 reading
test de Validacion = Validation test

All the results show an amount of time in miliseconds or seconds, depending on test, that it takes to do the selected test.
I imagine that the slower the disc reads the weaker the laser. I unfortunately did not see any tests that give results of the actual amount of errors while reading the disc.
I found a couple forums discussing this app, but they were all Spanish. I didn't get any more understanding of what the Validation Test results are actually reporting. If anyone knows already please chime in.

Disclaimer:
I have never used this prog before today so this is all just educated guessing.

Thanks again TNA!

Yepp, I know no program which is available for direct testing of those errors.
You can just test, if it "hangs" at a point or read-speed is slow (if it is not your laser ^^).
(High PI-Error-Rate gives a slower reading, high PI-Failure-Rate gives more "hangs".)

Btw.: The only app, which shows "read-errors" is HDL afaik, but not for correctable read-errors.

(dre=dirty read error?

Sorry, that I'm such kind of stupid in this case. :-/ )

Don't worry about feeling stupid, it's wiser to ask and learn then to fear looking stupid, just depends on who is answering lol. DRE stands for Disk Read Error.

I think this app is a great idea, if I could code I would be working on it right now...

**TnA** · 11-08-2008,08:54 AM

"dirty",... ^^
Don't know, what I thought before,...
Never mind. It was ~6AM and I didn't slept before.

THX for clarifying it.

**Dangwoot** · 11-08-2008,12:53 PM

i kind of figured this app was a good idea now i just need a coder to put my thoughts into fruition lol.

**ps2dragon** · 11-08-2008,09:22 PM

Actually, couldn't you just use something llike Norton Disk Doctor for Windows to detect if there are any disk read errors? There might be some free software out there, but I guess you wanted something like this to run on the PS2?
