!! Tiger, Quark, and Ethernet Disk in Studio

Greetings all,

I am running a small design studio. All the terminals are running Tiger, all G5s.

We had been using one of the work terminals as the mail file server, until recently when I decided to purchase the LaCie Gigabit 500MB Ethernet Disk.

It seemed perfect for our needs.

Anyway, we have been having problems with dissapearing files and not being able to save our work on the fly 'file does not exist. etc', having to manually overwrite older files to keep the work, in general, a real pain. Worse, it's a threat to business that I could potentially lose a day's work on a file (we backup every night.)

My equipment supplier is saying that the issue is with Quark.

Has anyone here had problems with Quark and networking?

I find it categorically absurd that I am being told people should work on files locally and then save to the central server. That is a recipe for disaster with multiple people accessing files to make adjustments.

Files must be stored, on a network, to a central repository.

So what I am asking is, what is the airtight way to have a networked environment with a central location for files, where people are using Quark?

Any thoughts would be greatly appreciated....

Cheers

Scott
