H The head number of the track to be formatted. ( L = 0 ) In LBA mode, this register specifies LBA address bits 24 - 27 to be formatted. ( L = 1 ) Input Parameters From The Device Sector Number In LBA mode, this register specifies current LBA address bits 0-7. ( L = 1 ) Cylinder High/Low In LBA mode, this register specifies current LBA address bits 8 - 15 (Low), 16 - 23 (High) H In LBA mode, this register specifies current LBA address bits 24 - 27. ( L = 1 ) Error The Error Register. An Abort error ( A B T = 1 ) will be returned under the following conditions: The descriptor value does not match the certain value. (except 00h, 20h, 40h and 80h) The number of assign(40h) exceeds the maximum number of reassign table entry. No spare data sector to be assigned. In LBA mode, this command formats a single logical track including the specified LBA. Explanation for descriptor Descriptor : 00h The sector of data will be initialized to 00h. Descriptor : 20h The sector will be unassigned to the original location from the reassigned location. Descriptor : 40h The sector will be assigned to a spare data sector. When being accessed by next command, the spare sector of data will be used automatically. The assigned sector can be unassigned with a descriptor 20h. Descriptor : 80h The sector will be registerred as a bad sector. Thereafter, the sector reports BAD BLOCK to E R R O R Register on Read commands. But the sector will not report BAD BLOCK if the sector is written by Write commands. 88 OEM Specifications of DTNA-2xxxx 2.5 inch H D D
