Icon shows following data:

• Current load of a logical disk that is most loaded
• Current temperature of a most hot physical disk

Tooltip shows following data:

• Disk load of each logical disk
• Temperature of each physical disk (admin rights required, disks must support S.M.A.R.T.)
• Processes that use disks most of all
