if you don't have Solutions Enabler installed you can download stand alone executable for pretty much any OS and query your disk that way. For example here is an output from inq on a Windows box  ------------------------------------------------------------------------------DEVICE              :VEND    :PROD            :REV   :SER NUM    :CAP(kb)------------------------------------------------------------------------------\\.\PHYSICALDRIVE0  :DELL    :PERC 6/i        :1.21  :           :      -----\\.\PHYSICALDRIVE1  :EMC     :SYMMETRIX       :5773  :1800040000 :        2880\\.\PHYSICALDRIVE2  :EMC     :SYMMETRIX       :5773  :1800159000 :        2880\\.\PHYSICALDRIVE3  :EMC     :SYMMETRIX       :5773  :180015a000 :        2880\\.\PHYSICALDRIVE4  :EMC     :SYMMETRIX       :5773  :180015b000 :        2880\\.\PHYSICALDRIVE5  :EMC     :SYMMETRIX       :5773  :180015c000 :        2880\\.\PHYSICALDRIVE6  :EMC     :SYMMETRIX       :5773  :180015d000 :        2880\\.\PHYSICALDRIVE7  :EMC     :SYMMETRIX       :5773  :180015e000 :        2880\\.\PHYSICALDRIVE8  :EMC     :SYMMETRIX       :5773  :1800093000 :    70709760  inq has a lot more options, good tool to have on a box where SE is not installed.
