S

Spindle state of the device:

^ = disk spinning at correct speed; tape loaded

> = disk spinning up; tape loading

< = disk spinning down; tape unloading

v = disk not spinning; tape unloaded

= unknown spindle state

W

Write-protection state. For disk drives, a W in this
column indicates that the device is hardware write-
protected. This column is blank for units that comprise
other kinds of devices.

C

Caching state of the device:

a = read, write-back, and read-ahead caching enabled

b = read and write-back caching enabled

c = read and read-ahead caching enabled

p = read-ahead caching enabled

r = read caching only

KB/S

Average amount of data transferred to and from the unit
during the last update interval in 1000-byte increments.

Rd%

Percentage of data transferred between the host and the
unit that were read from the unit.

Wr%

Percentage of data transferred between the host and the
unit that were written to the unit.

CM%

Percentage of data transferred between the host and the
unit that were compared. A compare operation can
accompany a read or a write operation, so this column is
not the sum of columns Rd% and Wr%.
