Water can damage the tape which can lead to data loss if untreated for too long. If your tape contains important data, you should be aware this could be lost. Do not attempt to fix your tape from water damage, such as from heat or freezing your tape, as this is likely to only decrease the chance of data restoration. Instead, contact a data recovery specialist such as Ontrack, who can recover almost all your data by using their specialist equipment to dry the tape and read its content.
