Methods and a computer program product related to the management of possibly logically bad blocks in storage devices are disclosed. A logically bad pattern is placed in a standard size data block if data associated with the data block has previously been stored or is waiting to be stored, but has subsequently become lost. The logical block address associated with the data block is stored in a bad block table. The possibly logically bad pattern is able to be detected, and the bad block table is checked to determine if the data block to be read is in fact Logically Bad. A data check response may be given if the logical block address is present in a Bad Block Table. The possibly logically bad pattern may have a first predefined data portion and a second predefined data portion and may be repeated to fill the standard size data block.
