While your on the subject of Cache, here is what I foundâ€¦
I am using Windows 2000 Professional and Nero ver 184.108.40.206 with a Sony DRU500a drive and I have been buying and using several brands of cheap 4x -R media. I was never able to burn faster than 2x until I read the posts in this and another forum. I had flashed my firmware to 2.0f but had not followed the correct procedure.
I did not know you had to disable the DMA transfer mode when I flashed my Sony DRU500a to version 2.0f. I read this in another forum where they were talking about Windows XP, but it also worked for Windows 2000. Here is how you do it: Control Panel -> System -> Device Manager -> IDE ATA/ATAPI controllers -> right click on the Primary IDE Channel -> choose "Properties" the "Advanced Settings" tab
and change transfer mode to "PIO only" for both device 0 and 1. Do the same for the Secondary IDE Channel. You will then have to reboot. Be sure to disable any packet writing software before flashing, I removed the software. After flashing the firmware to the latest version, presently 2.0g you will need to go back and change all of these setting back to "DMA if available".
After flashing I could still not write faster than 2x with -R media, so I tried the following:
After flashing my firmware to 2.0g I went back into: Control Panel -> System -> Advanced -> Performance Options -> Applications -> Virtual Memory -> Applications -> change, and set my Page file sizing for all my drives from the windows default to 3000 meg minimum and 4000 meg maximum (3 gig and 4 gig). After making this change I have been able to burn all 4x -R media at 4x. I can burn a full movie (4.5 gig) from my harddrive to a disc in right at 15 minutes! This is the same media that had taken 30+ minutes previously. Media I had bought online at 25 pieces for $23 including shipping! Cheap! Now $21 including shipping for 4X media (SKY) from YesBuy.net. The defaults at 3 gig and 4 gig are overkill and can probably me lowered, my son is using 1 gig and 2 gig without a problem.
Another note, after spending my $100 dollars for DVD XCopy Gold, a pair of good programs, I got an E-mail from PC World about DVD Shrink v2.3. A free program that is excellent for ripping DVD's for recording to a DVD disc. Now I use this FREE program exclusively, it allows you to rip a copy of a movie to your harddrive, re-authoring so it can fit on a single DVD, and then make as many backups as you feel comfortable with (with all of my kids and there friends I seem to loose about a DVD a week getting broke, damaged, or disappearing) Did I forget to say this is a free program?
