Thanks to all who responded to my earlier question regarding System 7.0 and Virtual 2.0. Now can virtual memory utilities such as these coexist with automatic disk optimizers such as DiskExpress II? I understand that Virtual needs its disk space to be contiguous, so an optimizer is necessary at some point, but can they both run at the same time? Thanks, Mike. -- Michael A.

Using Disk Express II and Virtual would be bad if you optimized the swapfile while using virtual. You could however, partition your hard drive and have one partition for your swapfile only (this may slightly reduce your swapping speed though). From personal experience-I tried using DiskExpress II and Virtual (with the swap file on another partition) and may computer froze. No damage was done, but it was obvious that there were going to be some problems although I haven't called either software company to discuss the problem. -Mike Darweesh weesh@unclejack.crd.ge.com

This seems to be happen automagically. Examining DE II's Volume Info shows the swap file (the only file on my disk that's 13 Meg :-) as "Anchored." I presume that DE II leaves such files alone. >Personally, I think DiskExpress is a well written & designed utility, >but I think it's a bit compulsive to have to have yur HD optimized >everyday.

To make DE II stop optimizing while you're working, activate DE II, hit the Status button (the only one that shows, I believe), and hit Cancel. Note that the "Optimize Automatically" box is still checked. DE II will then perform the optimiziation later. If you leave your machine on all the time (I do) it will be fully optimized every morning (or whenever you get back to your Mac). Flip side, joe piazza --- In capitalism, man exploits man.

Disk Express II takes pains to make sure it doesn't move your swapfile. So, in theory, it should work fine. I've had version 2.04 running fine under virtual, but I haven't run virtual much lately, so most of the time, I'm running it without virtual. ============================================================================= Steve Bollinger ____/| 909 Church St. Apt C \ o.O| Ann Arbor, Mi. 48104 =(_)= (313)-662-4073 -home (313)-763-3070 -work U billkatt@mondo.engin.umich.edu -ACK ACK ACK ACK!

No damage was done, I think the problem was related to your partitioning software. I use Virtual 2.0.3 and DiskExpress II together on a regular basis on the same Apple 40Mb drive. In the DiskExpressII control panel, the Virtual swapfile shows up as being "anchored", so it is never optimized at all. chaz -- -- Joan Rivers Slaughters Ninety-Five Chinese Physicists in drunken rampage. -spew clarson@ux.acs.umn.edu AOL:Crowbone

I concur (the desire to have your disk always optimized seems a bit, well, anal-retentive, doesn't it?). More troubling to me is the sheer number of trap patches that DiskExpress II does to do it's job. With all of the INIT incompatibility/weirdness going on in the world, it's the last thing I need. I now use Norton's SpeedDisk about once a week. After the first time (which took 45 minutes on a 140 MB disk), it now only takes about 20 minutes to fully optimize my disk. Plus, I use Norton's DiskDoctor program to fully check out the health of my HD before I do the optimization, which is an added value to the package. Norton's optimization of System and INIT files does seem to make the boot process (or at least my boot process) faster... ///////////////////////////////////////////////////////////////////////////// / Robert Hammen | Macintosh enthusiast & publishing guru, looking for a job / / hammen@ddsw1.mcs.com | 70701.2104@compuserve.com | GEnie: R.HAMMEN / /////////////////////////////////////////////////////////////////////////////
