On SSD's though, this would prevent TRIM from functioning properly and make the SSD appear as full to the controller which would hurt performance. So I tend to not erase SSDs with random data before encryption. The other thing is if you TRIM NAND cells on your SSD their contents should be unrecoverable as opposed to standard hard-drives. -- Thomas _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
