摘要:
Provided are a method, system, and article of manufacture recovering remnant encrypted data on a removable storage media. An end of data (EOD) marker is detected on a removable storage media, wherein a first encryption key is associated with data preceding the EOD marker. Following the EOD marker, an identifier of a second encryption key associated with data following the EOD marker is read in response to detecting the EOD marker. The identifier is used to access the second encryption key and the second encryption key is used to decrypt the data following the EOD marker.
