Abstract:
Methods, system and computer program products for detection of frequent improper removals of and changing writing policies to prevent data loss in memory sticks. Exemplary embodiments include a method including detecting insertions of the memory stick, detecting removals of the memory stick, tracking a number of times the memory stick has been docked when removed, tracking a number of times the memory stick has been undocked when removed, determining a removal ratio of times the memory has been removed when docked to the number of times the memory stick has been removed when undocked, comparing the removal ratio to a predetermined threshold, caching writes and directory updates, and committing the writes and directory updates to the memory stick when the removal ratio is below the predetermined threshold and, flushing all writes and updates to the memory stick when in the removal ratio is equal to or above the predetermined threshold.
