Re: [H] Inexpensive blank DVD media
The problem isn't so much doing the scan...there are a handful of tools out there that can do it, and a handful of drives that support it (and a handful of those that can scan with any sort of consistency). The problem is being able to interpret the results properly, based on the speeds, drive used, the media, and the scan parameters. If a single element is off or misrepresented, the results are completely worthless. At any rate, I don't have the time at the moment (about to leave) to explain it in detail. :) Greg - Original Message - From: Thane Sherrington [EMAIL PROTECTED] To: The Hardware List hardware@hardwaregroup.com Sent: Wednesday, August 17, 2005 5:18 AM Subject: Re: [H] Inexpensive blank DVD media At 10:36 PM 16/08/2005, Greg Sevart wrote: Have you performed PIE/PIF and PO scans on these discs after some time has elapsed since burning?

Just found this: Verbatim 16x DVD+R/-R (100 ct) at OD for $37.99 http://www.fatwallet.com/forums/messageview.php?pos=110catid=18threadid=50 8625 Are these any good?

A modern drive with modern media produces a terrible result when burning at low speeds. While conventional wisdom might suggest that burning an 8x disc at 2x would result in a better burn, the PIE/PIF and PO scans provide extremely strong evidence that the newer dyes and drives just don't work well at low speeds. Indeed, I've seen better burns on 8x media when written at 12x than when written at 4, 6, or the even the rated 8x. In short, if you want your discs to have as long of a shelf life and readability as possible, buy a quality burner, use quality media, and burn the discs at least at the rated speed. Greg
Different take on RE: [H] Inexpensive blank DVD media
My advice for those that burn a number of disks -- Buy Good or Great 8X media - the cost savings from going to 16X to 8X more that offsets buying the great media. Then buy another DVD burner -- at $50 you will offset the media cost differential. Then either copy to both burners at once - or run different copy jobs on both burners at the same time. I do that 95% of the time and have yet to burn a coaster as a result. Or I can rip on one and copy on the other. All I use is TY or Verb. - 50/50 8X and 16X but in so doing I have never unhappy with an 8X burn speed as I have been using the dual DVD option for over a year. Since I currently have another DVD burner laying around, I just might toss that in the case too - would like to see how it burns off the SATA side. Again - at $50 I don't know that it's a big deal.
