If the logically pad pattern is detected, a block address that is associated with the standard size data block is added to a bad block table. If the logically pad pattern is not detected, it may be determined if the block address associated with the standard size data block is in the bad block table. If the logically pad pattern is not detected and if the block address associated with the standard size data block is in the bad block table, the block address may be removed from the bad block table. The logically bad pattern may have a first predefined data portion and a second predefined data portion and may be repeated the requisite number of instances to fill the standard size data block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Managing logically bad blocks in storage devices","description":"At least one standard size data block of a storage device is scanned for a logically bad pattern.
