Don't forget you can get bios updates for those machines too. Just key in your service tag number at Dell's support website. After an F9 reset, is the controller still in AHCI mode?

I would guess there's just too much I/O going on for the controllers to handle. How have you managed to get 8 SATA ports in the first place? The most you normally get on a single chipset is 6.

For any sort of conversion, I'd imagine it's always a good idea to use the best quality source possible - after all, converting isn't ever going to make something better! In this case I'd say that's the h.264/mp4 one. Run the mp4 through DVD Flick / ConvertXtoDVD etc and then burn the output (a VIDEO_TS folder) with ImgBurn.

Duplicators normally have a bog standard hdd in them. The problem you've got is that you're going about it in the wrong way... you should be using software that reads once and writes to many - ImgBurn obviously doesn't do that. The best thing you could do is buy a proper 'hardware' duplicator unit.

Try again at the remaining supported write speeds. You've arleady tried 'MAX' (i.e. 6x), so now try 2.4x and 4x. Don't reuse the disc(s) that failed, that isn't a fair test. If it keeps failing, try cleaning the drive with a cleaning disc.

Maybe you've got DMA issues then. It's not normal for a drive to burn at 0.6x speed! Of course I guess it's also possible that the drive was just finding it *really* hard to burn the disc and that's what slowed it down so much. As for the service pack 1 thing, check its release notes. Microsoft make the service packs for a reason.

See if this download of SB02 is the same. http://www.samsungodd.com/eng/Firmware/FWDownload/FWDownload...geNumber=1&product_code=&os_no After that, if it still have trouble recognising discs and/or burning your Verbatim ones (at 8x speed), you might like to thing about cleaning the drive with a cleaning disc... or just buy a new drive (there isn't much difference in price between a cleaning disc and a new drive!)

The first error is the real one... Update the firmware on your drive. http://www.firmwarehq.com/Samsung/SH-S222A/files.html Update ImgBurn. Buy some decent quality discs - 'UME02' are rubbish.

Is your source file on a USB drive? It looks like you're only getting USB 1.0 speeds. You're probably wasting your time by trying to burn at 1x, why don't you put it on 8x and see how it goes. If you have to burn at 1x (in reality, 2x) to get a decent burn then clearly you shouldn't be using those discs or drive. You should install service pack 1 for Windows 7.

It lets you add loads of different files... including BIN and ISO files.
