Very real issue. Your IDE and SCSI disks may randomly leave recoverable data around if they hit a block that is iffy and mark it bad before it fails. Flash file systems are very very likely to leave old data around but fortunately are much smaller and therefore easy to encrypt or blank wholesale (or indeed blowtorch erase 8))
