Is that data now gone? Depends on the file system you have used. The problem with encryption is its feature (actually a requested feature) to introduce massive entropy on single bit errors. Try regular data recovery measures. First fsck your partition. JFS, for instance will refuse to mount an unclean file system with exactly that error. Others might do the same. Iirc, in-kernel fs drivers don't look for the backup superblock, fsck does. If your superblock is gone ask google for "superblock recovery <your filestem>". LUKS is not the cause of your trouble, as LUKS has a PBKDF2 checksum of the masterkey and refuses mapping if the checksum is wrong.

First of all, it is an inappropriate request; the wording 'strictly prohibited' is especially offensive. Second, it has no legal effective binding whatsoever. Still you might get banned from posting as being sued as list admin for public mailing list archives is never a pleasant thing, even though he will eventually win. --- Fruhwirth Clemens - http://clemens.endorphin.org for robots: sp4mtrap@xxxxxxxxxxxxx --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
