Fragmented hard drive with 2007.

We have been using SW 2007 at my work for a while now and I recently
received a new Dell computer. The page file was set to my C drive where
the SolidWorks application is installed. The problem I seem to have is
after using SolidWorks for an extended period of time, I get a Run Time
error and my C drive is fragmented to 40%. A co-worker I spoke to about
this suspects it may be due to poorly written code. Has anyone else
seen this problem and do you have a fix? Any help would be appreciated.
Thanks.

 

What is an extended period of time? Hours, days, weeks? How is your
pagefile set? You should be using the 3GB switch and you should have
your pagefile set to 2 times installed ram up to 4gb. Your pagefile
should have the same maximum and minimum. If you have a lot of RAM set
the PagingExec to 1.

I have never seen a disk 40% fragmented but I'll take your word for it.
I have seen SW crash when allowing Windows to manage pagefile. Are you
saving your models on C:? Have you cleaned out the temp file in local
settings at any time? This is something that will cause SW to crash or
become unstable.

Of course you are only running SW on this Dell. No mp3 stuff. No CD
ripping, photo editing and of course no virii, trojans, spyware, etc.

 

The basic advice they used to give this time is to have the page file
preferably on a different phisycal drive but at its minimum on a dedicated
partition. This advise is independent of the release, they keep saying it
since 97.

I've noticed this on my compter also. Mine is fragmented to 15% and
when I run defrag it doesn't get any better. Before installing SW2007
I never had any issues with fragmented files. Something DEFINITELY
happened with 2007.

 

We have turned the 3GB switch back on and moved the page file from the
C: (os) drive to the D: (Work folders for cad files) drive and set both
the min and max to the same size at 4096 and we are currently not
expierencing the problem anymore... We will post here again if that
changes...

Forget the built in windows defrag... use Perfect Disk... it actually
works...

 

dirms also does a good job. Runs from the command line and can be made
to run from a batch file and scheduled.

 

I remember seeing info on setting the 3GB switch some time ago, but
since I didn't have anywhere near that much memory, I passed it by.
Where can I find info on how to set the switch?

Thanks in advance.

Go to www.kcswug.com/documents/3gb_switch_part_one,_two,_&_three.pdf and
start reading. It should give you about all you want to know. Not
necessarily ALL the answers, but certainly enough.

You don't need a lot of memory to need the 3GB switch. It controls how
much memory programs can use. This includes the cache you have set. If
you don't have the switch and have 2GB installed you will crash at
around 1.6GB of memory usage regardless of how much or little is
installed. On the other hand the 3GB switch will let SW use all the 2GB
installed. Even with 1GB installed it seems to help.
