Why can't I burn @ 12x?

[Scootin159]

Short specs (read system info in sig for more):

1.4ghz Athlon w/ KT133a chipset
Adaptec 29160 in a 32-bit slot
Quantum 10k III U160
Seagate Barracudda IV (IDE)
Plextor 12x/4x/10x CD-RW
Toshiba 12x DVD-ROM (IDE)

I did have MINOR disk activity (someone was taking a file off seagate drive (just a mp3, not real traffic), but I was burning off of SCSI HDD, so shouldn't be an issue).

Anyways:

I tried to burn @ 12x from both the Seagate & the Quantum & neither would get past 5% on the CD-R without a buffer underrun. I also can't burn from DVD-ROM -> CD-RW either @ 12x. However @ 8x I have NO PROBLEMS. Any ideas?

I had this problem. The fix for me is use the older driver. Don't use the newest driver from Adaptec. If you have WIndows 2000, use its Adaptec driver.

I have Windows XP and am using it's default driver....which one should I try switching to?

Which burning software? using Nero here w/ DMA enabled w/ WinXPPro burning an audio CD to audio CD ( on the fly...even as I'm posting this w/ iwill kk266 ...source BDV212B to Liteon 16x10x40 ) and 11 IE6.0 windows open. <edit> another one done. 9 mins start to finish.

The Windows XP one doesn't work with me (its like the new Adaptec driver). I kinda cheated and copy the Windows 2000's adpu160m.sys file. You might need a dual boot to get this working though, because Windows doesn't let you change .sys file while in the same Operation system. If you want the file, I can email it to you.

well I SHOULD be able to in theory just update it with the win2k driver. Do you have the whole .inf & everything? (I don't have dual-boot right now). What's the version # at least so I can try & find it?

 

[Jgtdragon]

Well, I just needed to replace one file, adpu160m.sys from Windows 2000. I backup the XP's adpu160m.sys by renaming it.

yeah, but I won't be able to replace this file without a dual-boot. Hmm...wait, maybe a bootdisk? Anyways, want to e-mail it to me.Newton_Scott@roberts.edu

I have the same Plextor 12/4/32 with an Adaptec 19160. Under Win2k, i tried many different drivers and was never able to burn at 12X or even 10X. Like you, I could burn at 8X also. I'm using WinMe now and burning at 12X again with very little CPU utilization. I love my SCSI CD-RW again! damn Win2k/XP drivers.......:disgust:

I know what you mean soulm4tter. I first thought my burner was broken haha I got the burner from Mastertech01. Really nice and helpful guy by the way. When I test it in Windows 98Se it worked fine, but not in Windows 2000. Like usually I updated all drivers when I got new stuff on Windows 2000 (my main OS). I can't burn in Windows 2000 with Adaptec's new driver. Finally, I removed the new driver and try the default windows 2000. Bingo, it worked.

Tried WINXP with its default driver and it didn't work, so I did that little trick while in Windows 98. Everything is good now.

Works now....buffer is staying pegged @ 98%. Thanks guys.

 

[soulm4tter]

hmm, i wonder why adaptec doesn't fix the driver. Does the driver work fine in all other respects?

Great! Glad I could help out.

Haven't noticed any issues yet, but also only been using it for an hour or so.
