The Physical Sector defect descriptor specifies the location of a defect that is the length

 

of a sector. The Bytes From Index defect descriptor specifies the location of a defect

 

that is no more than eight bytes long.

 

 

 

 

Each descriptor is comprised of the bytes shown in Table 5-18. The Cylinder Number

 

of Defect is the most significant part of the address, and the Defective Sector Number

 

or Defect Bytes From Index is the least significant part of the address. A value of

 

FFFFFFFFh in bytes

to is ignored
