Re: cache explorer
Thanks for this tool. I think it might have a problem with my Plextor PX-712A, but I am not sure.

"cachex.exe -p -r 0xd8 F" returns the following:

Quote:
CacheExplorer 0.7

Drive on F is PLEXTOR DVDR PX-712A 1.08

[+] Plextor flush command: accepted
[+] Plextor flush tests: -1/5
The -w command doesn't do anything.

Re: cache explorer
There is another problem - fetching information from my BenQ DW1655 freezes the whole system. Tell me if you need more information, such as chipset or unit connection.

Re: cache explorer
Hi Sebastian,

Can you add the debug switch '-d' and post your results ?

At first look it seems you PX-712 does accept Plextor's FUA command
but that it does not actually flush the cache, which is quite interesting.
Did you try EAC's -usefua switch with this drive, and if so what kind of
ripping speed difference did you measure ?

Hello!

Quote:
CacheExplorer 0.7 - spath@cdfreaks.com

Drive on F is PLEXTOR DVDR PX-712A 1.08

[+] Plextor flush command: accepted (status = 0)
[+] Plextor flush tests: -1/5
I did try -usefua and the results were not consistent. The detection feature in EAC reported that the drive does cache several times and that it does not cache a few other times. I didn't notice any difference in ripping speed.

Also, any idea why the whole system freezes when querying information from my BenQ unit? It's set as primary slave and my chipset is a SiS 648FX. The Plextor is secondary slave. I didn't notice any problems with my NEC ND-4551A which is set as secondary master.

Re: cache explorer
Hello, spath. Thank you for this little utility - it should become very useful for all EAC (and the rest) users.

I have a similar problem to Sebastian's, albeit not the same.

Setup: WinXP SP2, BenQ DW1640 set as master, alone on the channel. VIA KT333 chipset. I have Daemon Tools installed. They're disabled, but the virtual drive is active. I mention them because they used to interfere with ASPI in the past here. I know you used SPTI, but just in case... I don't know what exactly they might or might not do.

Problems:

1. The programme works fine with BenQ's BSLB firmware. I was curious about the newer firmware results, but the whole system freezes when I try tu use it with BSPB or BSQB firmware. It looks like a BenQ-specific problem, considering Sebastian's experiences.

The system freezes after displaying this only:
Code:
Drive on G is BENQ
Normally, it displays this as the drive's name:
Code:
Drive on G is BENQ    DVD DD DW1640   BSLB
2. I set the programme to 16 retries. Sometimes, it just stops doing nothing after the first trial. The command line I used: "cachex.exe -i -d -c -l 15 -s 0 -n 16 g:"


3. I don't know whether it is a problem or not: sometimes, it displays different amounts cached by the drive. An example:
Code:
[+] Testing cache line size:
info: using command BEh
info: 16 test(s), c/nc ratio : 4, bursts of 1 sector(s)
 2 kB / 1 sectors (92.86 .. 1.08 -> 4.47)
 2 kB / 1 sectors (98.94 .. 0.70 -> 2.86)
 2 kB / 1 sectors (105.40 .. 0.87 -> 4.70)
 147 kB / 64 sectors (99.08 .. 5.06 -> 63.27)
 2 kB / 1 sectors (98.54 .. 0.71 -> 3.06)
 2 kB / 1 sectors (93.08 .. 0.74 -> 3.04)
 2 kB / 1 sectors (98.23 .. 0.86 -> 4.74)
 2 kB / 1 sectors (105.50 .. 0.73 -> 3.04)
 2 kB / 1 sectors (92.52 .. 0.71 -> 3.07)
 2 kB / 1 sectors (98.83 .. 0.74 -> 3.06)
 2 kB / 1 sectors (105.78 .. 0.85 -> 4.74)
 2 kB / 1 sectors (98.85 .. 0.87 -> 4.41)
 2 kB / 1 sectors (98.86 .. 0.84 -> 4.67)
 2 kB / 1 sectors (105.15 .. 0.83 -> 4.71)
 2 kB / 1 sectors (98.95 .. 0.76 -> 3.15)
 2 kB / 1 sectors (99.42 .. 0.71 -> 3.06)
Is this normal or is my drive / system at fault?

Let me know if I can supply any additional details you might want to know. And thank you again for creating this app.

Re: cache explorer
@Sebastian:

I found the problem, it's a bug For now use '-i' instead of '-r' for
the plextor FUA test. Regarding the freeze, it seems BENQ drives have
a problem.

@Marius_The_Mad:

Thanks a lot for the investigations, it's very useful. It looks like some
BENQ drives have problems with the INQUIRY MMC command, I will try
to get a drive and look into it. Regarding 2., do you still see drive activity
(LED flashing) while nothing happens on the screen ? If you wait a bit,
do you get a 'test aborted' message ? Regarding 3., the log just means
that your drive does not cache.

Re: cache explorer
Hi,

I can't get the test to complete with any of my drives. I always get a "test aborted" result.

Results with my burner:
Code:
cachex -d -i -c -n 1 e:

CacheExplorer 0.7 - spath@cdfreaks.com

Drive on E is LITE-ON DVDRW SOHW-832S VS0M

[+] Buffer size: 2048 kB, read cache is enabled
[+] Supported read commands: BEh
[+] Testing cache line size:
info: using command BEh
info: 1 test(s), c/nc ratio : 4, bursts of 1 sector(s)
 test aborted.
And with my dvd reader:
Code:
cachex -d -i -c -n 3 f:

CacheExplorer 0.7 - spath@cdfreaks.com

Drive on F is JLMS    XJ-HD166S       DS1E

[+] Buffer size: 512 kB
[+] Supported read commands: BEh
[+] Testing cache line size:
info: using command BEh
info: 3 test(s), c/nc ratio : 4, bursts of 1 sector(s)
 test aborted.
I have no idea why

Regards.

Re: cache explorer
Hi,
Looks like great tool, but I think it has problem with SCSI drives. Of course, i know that those drives are rarely used but ...
My system has Adaptec AHA-2940AU and there is Yamaha CRW-F1S and Plextor PX-40TS. When I try to explore anything on these drives, I get this message:
Quote:
CacheExplorer 0.7 - spath@cd......

No problem, my pleasure.

The LED doesn't flash while CacheExplorer suddenly stops and if I wait for a while, I do indeed get "test aborted.". Previously, I didn't wait long enough, it seems.

Also, I now see it happens randomly, not only after the first trial.

Thank you for the explanation. That's nice to know, especially when EAC tells otherwise. Could you post some general guidelines on how to correctly interpret the report for us, less drive-savvy ones?

Thanks for the reply.

Re: cache explorer
Hello, thank you for this utility. I tested it on both of my drives, it worked find on my LG4167, but I had the same problem with my BenQ 1640 that other's have experienced.

I encourage you to make this test easily available so that it becomes a standard procedure used to provide information for databases like the DAE Features webpage. Perhaps ask them if they want to host to utility?

I am one person who got burnt thinking that the LG4167 drive doesn't cache audio data, because that is what EAC reports. But your utility confirms the information from Feurio that the LG4167 does infact cache 36 Kb of data.

I'd be interested in people using this utility to test the new Plextor Premium2 CD burner, because I am looking for a new dedicated CD ripping drive.

Re: cache explorer
I was wondering about one thing... If it comes out that a drive caches one sector only (like it is the case with my NEC), can I tell EAC that the device does not cache? IIRC, if the cache is smaller than the number of sectors EAC requests, one can tell EAC that the unit doesn't cache. Please correct me if I am wrong.

Re: cache explorer
0.8 - fixed problems of '-i' with some BENQ firmwares (thanks to Mariusz)
- fixed bug with '-p -r' (thanks to Sebastian)
- fixed "1 sector cache" false results (thanks to Mariusz)
- added '-m' option

BTW this PX-W4012A looks really good, all commands support the FUA bit !

Re: cache explorer
Thank you for the new version. It appears to have cured all the problems I had with it and my drive.

Thanks.

Re: cache explorer
Thanx spath, this tool of yours is very handy.

I managed to get the basic cache info for my two drives using the basic arguments -i -c -n 3. Neither one caches audio as EAC also indicates.

NEC 3500AG and TSST TS-H352A.

Could you also please elaborate a bit on all the -switches and -arguments that can be used on Cachex including creating an output log. That could also be included in the next cachex.txt when you decide to update.

Thanx again

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

Re: cache explorer
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,

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
