Why do my device sizes appear as negative values in SQL EM?

A. A. You may also find that because of this error it will not let you make any changes.

This is caused by a known bug in Enterprise Manager when there is greater than 2Gb of free space on a disk. It was fixed in 6.5 SP3 and above. If you are running SQL EM from a client then you will need to apply SP3 to that as well.
