Fru : Field Replaceable Unit (Byte 14); Sense Key Specific (Byte 15 Thru 17) - IBM DDRS-39130 - Ultrastar 9.1 GB Hard Drive Specifications

12.2.9 FRU : Field Replaceable Unit (Byte 14)

The F R U (Field Replaceable Unit) field value will always be zero.

12.2.10 Sense Key Specific (Byte 15 thru 17)

The definition of this field is determined by the value of the sense key field.
12.2.10.1 Sense Key Specific - Illegal Request (Sense Key = 5h)

SKSV Sense-key specific valid
0 Sense-key specific field is not valid.
1 Sense-key specific field is valid.
C/D Command/Data
0 Indicates that the illegal parameter is in the data parameters sent by the initiator
during DATA O U T phase
1 Indicates that the illegal parameter in the command descriptor block.
BPV Bit Pointer Valid
0 Bit pointer field is not valid.
1 Bit pointer field is significant.
Bit Pointer Bit Pointer indicates which bit of the byte number reported in Field Pointer is the bit in
error. When a multiple-bit field is in error, the pointer point to the most significant bit of
the field.
Field Pointer Indicates which bytes of the command descriptor block or of the parameter data was in
error. Bytes are numbered starting from zero, as shown in the tables describing the com-
mands and parameters. When a multiple-byte field id in error, the pointer point to the
most significant byte of the field.
