I used cryptsetup to perform the following function<br><br><div style="margin-left:40px">cryptsetup -y --cipher aes-xts-plain --key-size 512 luksFormat /dev/sdb1<br><br></div>An error occured saying it couldnt be performed which i pretty much ignored and just thought i won&#39;t bother.  I did note that it mentioned about kernel compatability though.  The drive appears to be encrypted and wont accept the passphrase set.  This has just under 1.5 tb of information i can&#39;t afford to loose.  Do you have any solutions, i have looked online but am absolutely stuck<br>
<br>Cheers<br><br>Si<br>
