KembaraXtra-Computer Terms – bad block:
A bad block is a defective location in a storage medium or memory device that cannot reliably store or retrieve data. When a computer system starts up or performs a diagnostic check, the memory controller may identify these faulty areas during a self-test procedure. Once detected, the system marks the bad block so that it is not used for storing data. Avoiding these defective areas helps prevent data corruption and ensures the reliability of the storage system.
