Some customers have found that while using SEE FD 8.2.1 mp 5 with multiple internal hard disks, if the primary disk is decrypted before the secondary disk, access to the remaining secondary disk is lost and the data cannot be recovered using the SEE FD Access or Recover Utility.
When using the SEE FD Recover utility, it is possible to decrypt the primary drive first before the secondary disk.
Engineering is currently targeting a fix for this issue to be released in SEE FD 8.2.1 mp 15, currently there is not a targeted release date.
