Disk Space reports in SIM

[Graham Cooper_4]

We have just upgraded from CIM7 to SIM.
The disk space report for our servers is showing incorrect information. The disk space availble and used is incorrect. The % used is correct.
Please can you advise why SIM is giving incorrect results where CIM7 was correct.
Thanks

By default, data collection is only run every 2 weeks (to keep traffic down on your network). You can choose to schedule it more frequently or run it on demand as needed.

Your data may be as much as 13 days out of date. Run data collection first and then your report should have fresh data.

I have changed this to 1 week.
It reports the total size of the disks incorrect as well.

By jove the lad is right.
The difference is a multiple of 1.048.

Seems some maths somewhere is a bit askew, but which one, CIM of SIM is wrong?

CIM agrees with with the properties page of the drive in Windows.

Does any one have any more info on a fix
