Power Record Disabled Scans

#1

There has been a lot of discussion lately about the use of Power Record so I had some spare time and conducted a test with one Media. What I did was used Plextools Write Transfer Rate test with Power Record enabled to find two disc that were similar in write performance, they are not identical but as close as I could get after scanning 15 different discs. One disc was burned at 16x with P/R and A/S enabled and the other was burned @16x with P/R and A/S diabled. Both discs were burned with Img Tool Burn @ 4464 Mb. Img tool does not add the lead in or lead out time to the burn so I am guessing you should add 40 sec to the times I post. Some people are going to ask why disable Power Record, well because I can and Plextor gave me that option, why I have no idea. :slight_smile:
Anybody is welcome to add their comments or findings to this and I wll try to add some other media at a later date. Here are my results.

Test 1 Power Record on.
Plextor 716A, 1.06 FW. TLA#0304
YUDEN000 T02. Fujifilm DVD-R 8x
Both discs checked with Media Quality Check and Judged good for 12x burn.
Burned @16x P/R on A/S on
Burn Time 5:49

Test 2 Power Record and A/S off
Plextor 716A, 1.06 FW. TLA#0304
YUDEN000 T02. Fujifilm DVD-R 8x
Burned @16x.
Power record was used for the Write Transfer test then Disabled.
Burn Time 5:14
Note the Red on the Sum 1 test, I think Plextor was nice enough to incorporate a Coaster indicator to Plextools. :slight_smile:

why’d the speed drop with PR OFF? it’s not supposed to drop at all (mine doesn’t). and how do you have a write curve if the discs were burned with ImgTool Burn?

#4

@drpino I tested both discs with power record on so I could get the discs as close as possible to the same then disabled P/R on the second burn. Some of these discs will go right to 16x with P/R enabled so I wanted to make sure I got two similar discs that P/R should have had an influence on the burn. :slight_smile:

ohhhh, i get it now.

Plextor 716A, 1.06 FW. TLA#0304
TYG02. Fujifilm DVD-R. 8x
Burned @ 16x P/R and A/S off.
Disc checked with Media Quality Check and Judged good for 12x burn
Simulated Write test carried out with P/R on then off
Burned with Img Tool Burn. Time 5:35 P/R off
Above scans are +R not - My mistake. :confused:
This media doesn’t seems as sensitive to P/R as +R. Looks to me like P/R would have kicked in around the 3.8 Gb mark and kept the PIE’s close to 20.
I think the point is: Let Power Record do it’s thing and if you turn it off don’t complain about your Plextor giving you bad burns.
Note the end speed of P/R Off write test 16.50x??

crossq, I still can’t figure out why your burn transfer rate graphs have so few OPC checks…

EDIT I figured it out. Those are simulation scans :o

#8

Yeah I wish I could afford the media to waste and do it properly, but a least it gives people an Idea of what P/R does when turned off. I Hope!! :slight_smile:

#9

even with PR OFF, that burn is just fine.

#10

Yes indeed!

I have NEVER burned a DVD with a PIF maximum less than 2 and your Sum1 scan shows a maximum of 1 PIF! :eek:

So even though I have burns with a lower PIE score I still have to :bow:

#11

Hehe. Guess this media wasn’t the best for this test as it burns pretty well in just about any burner. Wish I could get some media that Power Record was needed, then turned off to show the difference. Because that’s what I was trying to do.
BTW. drpino. what happened to that nice Avatar you had! :sad:

#12

this is my staple interim one whilst i look for an even better one :wink:

good example of how PR works…you should add Read Transfer Rate scans to your battery of tests to show how PIFs affect readability at high speeds (analagous to FFing @ 32X in a stand-alone).

#16

drpino. Thx I knew I forgot something important. :confused: Managed to get the read test for the P/R Off scan done and posted before my edit ran out but the P/R on scan I didn’t get in time. BTW. Tried to do the read test @16x and Plextools kept going back to 5X-12X, More software with a mind of it’s own. More reading required!!
@ G@M3FR3@K could you please add this Read scan to post #13. Please and Thx. :slight_smile: > done

#17

PX716 can only read single layer PRESSED DVDs @ 16X. burned (even bitset) +Rs and -Rs read at 12X max.

#18

Thx for the Info saved me some reading. Guess I am guilty of having different Brands of burners as they all are a bit differernt in scanning. :wink:

#19

no prob…you can see this if you go to Drive Information in PTPro under the READ tab it states the speeds with asterisks…
