Thanks! I was sure that someone would have explained a bit for me, as I was off on vacation for a while, just after I got this reply, but also because Shannon just put this question: On 06/01/03 0:46, "Shannon Nugent" <[EMAIL PROTECTED]> wrote: > Does it make any difference if you designate your entire harddrive (un > partitioned) as your scratch disk? I thought it might be an idea that I respond. When you use your hard disk for video, speed is very important. If your hard disk is fragmented, the speed is not as good as it could be, which can subsequently lead to bad videos. This can demand a longer explanation, that I will not go into here, but if someone needs it, I shall. One way to avoid fragmentation is to erase all contents on your drive, another to run a defragmentation application. The latter takes a lot more time than the first, if you do it right. This is where the concept of scratch disk comes in. If you only have one partition(the same as unpartitioned, if anybody should be in doubt), you will need to run a defragmentation tool every time you want peek performance for your video editing, but if you have two partitions, you can get by, just by erasing the scratch disk in its entirety, so that it is effectively defragmented. This of course means that you cannot use that partition for anything that needs to last longer, than until the next time you want to erase it to get it defragmented, and hence speed. If you have a large harddisk of say 80 GB, you can choose to use say 50 GB as a scratch disk, ensuring that it is not fragmented by formatting that part of your disk every time you need it. This can only be done by formatting and partitioning your entire drive. This will destroy all your data on your hard disk, so don't do it if you don't have backups of everything you need and everything you don't know you need, well, basically everything. So if you don't have a brand new drive or iMac with nothing on, you have to backup. Remember everything will be gone when you do the next step! When you have made your backups, start up from your latest Apple-System- or installation-CD and use the disk utility to make two partitions. The first for your system and all the files that you want to keep forever etc. and the second for the scratch disk. Remember that some systems (iMacs A-D) demand that you have the entire start-up partition within the first 8 GB, but if you have this size of hard disk, you may already know that. Then reinstall the system you are using, and copy the rest of your backups over. When you use iMovie the next time, remember to place your files on your new scratch partition, and when you need it the next time, remember to erase it completely so that it is clean and optimized.
