What does LBA stand for in SMART logs?

• A. Local Byte Allocation
• B. Layered Binary Address
• C. Logical Byte Access
• D. Logical Block Address — location of affected sector.

Answer: (D)

In SMART logs, LBA refers to the address of a specific block on the disk. Logical Block Address is how drives map data into a linear sequence of sectors, rather than using older geometry-based addressing. When a read/write error occurs or a sector is reallocated, the SMART record may note the LBA—that location points to the affected sector on the drive. This helps you pinpoint where problems occur and correlate them to data or patterns on the disk. The other terms listed don’t align with how drives reference data in SMART logs; they don’t describe sector addressing in the same standardized way. So the correct interpretation is Logical Block Address, the location of the affected sector.
