Hey Andy Thanks for the tips. > My advice would be to wipe the disk clean and start again, after backing everything up of course. =20 I have had to 'repair' ie, re-install 5 times this week so far. Admittedly I have been doing a lot of data juggling as part of the back up plan but the format is going to be a great breathe of fresh air...hopefully. Is vfat32 different from FAT32? Also I read on MusicXP.net that cluster size can have an affect as well, any ideas there? Also I was planning to install FruityLoops on the 60GB drive as it's the faster drive along with all my plug-ins and other audio editing app's. Is this something you would recommend? Keep system and everyday software on one disk and the audio stuff on the other? Also on the subject of disks...how would you suggest I partition the drives? I was think thinking about a 20Gb C drive and 20 Gb D drive on the slower 40 Gb drive and maybe just leaving the 60GB as one partition. I am not sure about this and was looking for some input. > Well it all depends which plugins - some use more CPU up than others. Make sure you are using the "smart disable for all effects" option, so that unused effects don't load up the CPU. Here I meant that I have 15-20 plug-ins installed on the PC but certainly not running in FL at any one time. Usually 3 or 4, sometimes 7 or 8 but I usually bounce these to audio and play them that way. The smart disable feature sounds handy. I remember when I had only a few plug-in's, FL ran fast and stable and now I am getting audio clicking and dropouts, which obviously is a problem.=20 The plan is to install the minimum of app's > http://www.musicxp.net I found this site yesterday and fed it through the printer. Its pretty good, exactly how good I'll tell you guys next week. The data is backed up and ready to go. Thanks in advance for any replies Cheers Ally
