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...
Drive is a LG GCE-8160B clone.
System is a SMP/dual P4 2GHz with WinXP

Those are examples of what I get :

Code:

C:\Download\eac\cachex>cachex -i -c -n 3 e:

CacheExplorer 0.8 - spath@cdfreaks.com

Drive on E is  HP       CD-Writer cd16b  2.00

[+] Buffer size: 2048 kB, read cache is enabled
[+] Supported read commands: BEh A8h(FUA) 28h(FUA) D4h(FUA) D5h(FUA) D8h(FUA)
[+] Testing cache line size:

 34 kB / 15 sectors

C:\Download\eac\cachex>cachex -i -c -n 10 -l 15 -s 0 e:

CacheExplorer 0.8 - spath@cdfreaks.com

Any clue to what is happening ?

Hi,

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

Code:

C:\download\cdr\cachex>cachex -i -c -n 4 -l 15 -s 0 d:

CacheExplorer 0.8 - spath@cdfreaks.com

Drive on D is  HP       CD-Writer cd16b  2.00

[+] Buffer size: 2048 kB, read cache is enabled
[+] Supported read commands: BEh
[+] Testing cache line size:
 no cache detected
 no cache detected
 no cache detected
 no cache detected

I'll check again on the other box if I did not made any error. That's the trouble of leaving advanced tools in the hands of clueless newbies like me...

Thanks again...

Jean

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

Buffer size: 2048 kB, read cache is enabled

For reference, although I don't really care how well it works Lite On SOHD-16P9S:

Buffer size: 254 kB

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.

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

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).
