I'm not DR pro, but let me have a WILD guess.

Here is an example:
http://www.forum.salvationdata.com/view ... =23&t=2438

"Next System LBA 000003A1 LLL CHS 000001.0.0005 PLP CHS 025C48.0.0005"

CHS = Cylinder / Head / Sector

LLL CHS = logical CHS ?
PLP CHS = physical CHS ?

LBA = Logical Block Address

The quoted example appears to be suggesting that LBA 0x3A1 maps to logical cylinder 1, logical head 0, and logical sector 5.

The PLP CHS value suggests that a defect has been remapped to physical cylinder 0x25C48, logical head 0, and physical sector 5 (???).

I suspect that the head number in both cases may be a logical one due to head mapping.

Sector slipping refers to the assignment of spare sectors at manufacturing time. LBAs corresponding to Primary defects are simply "slipped" to the next sequential sector.
