_LBA_FILTER_TABLE_ENTRY structure

Description

The LBA_FILTER_TABLE_ENTRY structure contains an individual LBA range for the LBA_FILTER_TABLE sent in an IOCTL_EHSTOR_DRIVER_UPDATE_LBA_FILTER_TABLE request.

Members

`StartLba`

The starting LBA of the LBA range for this entry.

`LbaCount`

The number of LBAs in the LBA range.

`ReadLock`

Set to TRUE if the LBA range in this entry is not readable. Otherwise, this member is FALSE and the LBA range is readable.

`WriteLock`

Set to TRUE if the LBA range in this entry is not writeable. Otherwise, this member is FALSE and the LBA range is writable

Remarks

An LBA range is valid only if LbaCount is > 0 and it is not overlapping with another entry in LBA_FILTER_TABLE.
