Problem with disk quotas

I haven't had much dealing with disk quotas; but it will happen soon!
Our SBS server has C, D and E drives; part of a raid trio.
All users 'Home folder' points at a folder on E' called 'Users Shared Folders'
There are some other shared folders on the 'E' drive.
A member of staff received a message stating low disk space when she tried to copy to a shared folder.
Now, I had a look at disk quotas on 'E'.
I'm confused because some people show a limit of 1GB, some show 500MB
Why? More confused because the user with the problem has 2.5GB in her private folder and she was trying to copy stuff to 'Company Pictures' folder.
Does disk quota not affect users Home folders?
And, her limit of 1GB, is that for anything else she puts on the 'E' drive in total.
I temporarily changed her limit to 2GB to rectify the problem.
There are about 10 Account Information Unavailable entries in Disk Quotas, how can I tell if these are safe to delete.
Any suggestions?

Disk quota are set on disk's. So, ALL files on one drive from one user count for the quota.

If the user with the problem had a quota set at 1GB, how come she has at least 2.5GB in her home folder and has added loads already to the Pictures folder? This is confusing me

Is she the owner of those files? They may be in her home folder, but she doesn't have to be the owner of the files.

I've just done some reading and discovered that if she creates a folder, but some one else poulates it, it could show as her allowance, therefore, thanks for your response and before I award points, can you tell me why some people have a 500MB limit and some have 1GB? It's not necessarily new and old users.

You can set the quota individually. You sure that no one has set the limits by hand?

Enforcing Disk Quotas for All Users

To enforce quota limits for all users, perform the following:

    * In the limit disk space set warning level to boxes, enter the values for the limit and warning level that you want to set.
    * Select the deny disk space to users exceeding quota limit check box.

Setting Disk Quotas for Individuals:

    * In the properties dialog box for a disk on the quota tab click the Quota Entries button.
    * In the Quota Entries for dialog box create an entry by clicking New quota entry on the quota menu and then selecting a user.
    * Configure the Disk space limit and the warning level for the individual user.

What do you mean with: 10 Account Information Unavailable

That you can see the SID string thingy? These accounts are gone. You can delete these.

Thanks scraane,
I've followed both bits of your answer.
You seem to learn more when things go wrong!
I'll delete most of those SID entries. One has 125MB of stuff, but I'll delete the others with zero usage.
Cheers
John
