If you use Wheezy or prior releases with the default kernel, queued TRIM is not used at all. No problem. If you use a 3.16 kernel (wheezy-backports, jessie default), you should get a blacklist entry that stops the use of queued TRIM on that drive. You may have data corruption if you use it with a kernel that both supports queued TRIM and does not blacklist your drive. Queued TRIM is an extension of NCQ to the TRIM command and is only a mildly attractive feature if it's working right. -dsr- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
