Hi, I having recently learned that the reason I have been having computer problems is because I only had 1.3 GB of hard disk space left on my eMac which has an 80 gb drive. First off, I didnt know you had to leave a certain amount of space for your computer to function. As I now understand it my computer was crashing and causing me thus to lose unsaved documents because virtual memory was eating up some and apparently all of that 1.3 GB. Apple support was nice, but could not answer more technical questions for me--in fact one support agent had never heard of virtual memory. My first question is why virtual memory would use that much hard disk space, when I have 768 MB of physical RAM? Second, why did I not receive any warning messages? The people at Apple said I should have received warning messages about low hard disk space. Third, when I restarted my computer it had instead of 1.3 GB available, 2.23 GB available. Did it EAT my documents to make more room? I'll admit I am a digital packrat so it would take me a long time if ever to notice if certain things are missing. I have now gone through and made 8 GB left available until I can get another external hard disk to do more backup. However, can someone tell me how my computer magically made over 1 GB appear after a hard shutdown and restart? Thanks so much!!!!! You guys are geniuses.
