6.1.5 Get function for the drive condition (hfbDiskStat)
<Name>
hfbDiskStat - Drive status acquisition
<Syntax>
#include <hfbras.h>
BOOL hfbDiskStat(PHFW_DISK_STATUS phfbDiskStatus);
<Description>
The hfbDiskStat function stores the drive conditions to a structure pointed by phfbDiskStatus.
The parameters of this function are explained below.
phfwDiskStatus:
This parameter specifies a pointer to an HFB_DISK_STATUS structure shown below that stores
the drive conditions.
typedef struct HFB_DISK_STATUS{
DWORD
Disk_Count;
DWORD
Disk_Status[16];
} HFB_DISK_STATUS, *PHFB_DISK_STATUS;
Disk_Count stores "2", the number of drive bays on this equipment.
Disk_Status[n] stores the condition of the drive on the drive bay (n + 1). Table 6-3 lists the
value that represents each status. Upper 16 bits are reserved. The values of those reserved bits
are undefined. Do not use those bits.

(*2) This value is not stored if the drive usage monitoring is not enabled.
(*3) This value is stored if the equipment is non-D Model.
(*4) This value is stored if the equipment is D Model.
