Biggest BS out there along with Adaptec ASPI and SPTD. SPTD will and can stop pc booting. Nothing to do except remove it manualy if can. Or replace with backup 'you have been warned'. All of the above including elaborate bytes elby driver can slow down cd, dvd, blu-ray and bdxl reading and writing. Again you have been warned, sorry for warning but it is important to not. SPTI as installed by microsoft is the best there is. No joking use nothing but that. If need an aspi layer try use nero aspi.dll search for it on nero site it is free. Place it in software folder and it should use it from there, or tell software to use it from there. That is all there is to know for keeping your microsoft os running in perfect health for optical drives. Another thing try get in the habit of unpacking in virtual memory or a sandbox to know the installer contents. Or better still ask your av, malware, trojan etc software company to detect instalation of these device and to notify you so can make decision to install product or not. Doing this will no doubt make those softwares think twice and maybe put a option to install or not, that is allow on os at all. Maybe then they get the idea that SPTI or nero.dll aspi is the best to use. Actualy I don't use nero, I prefer ImgBurn becuase it is better. Use other freeware tools for conversion if need video or audio done. Far faster than relying on nero bloat ware. Scuse if this upsets anyone, better to tell the truth than not to. Dangerous rating because they can stop pc from booting. Also make only coasters and have an optical drive that seems as if it only reads slow, one or all problems can happen.
Not these drivers on any microsoft os

Installed with Adobe Premiere Pro 7.0 for Windows. 1 Download FilterFix.zip, unpack and run it with administrator rights, select the pfc filter and click remove, rename or remove \Windows\System32\drivers\pfc.sys or \Windows\SysWOW64\drivers\pfc.sys, Reboot system.

This was probably installed on my system by Adobe CS4 Design Premium. Windows 7 Pro x64 refuses to run it, giving an error in the System log saying it's incompatible. It doesn't seem to have broken anything however.

Adobe Audition installed it. My dvd-burner lost possibility to burn Philips dvd-rw discs. But now I'm afraid to unistall it, because perhaps Audition will not work anymore.

Crashed my Win XP64 - \SystemRoot\SysWow64\drivers\pfc.sys has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver.
