I was hoping for a rather less intrusive option than backing up 10TB of data. Although its a backup of a backup (ie offsite) I was hoping there was a less drastic option available. I am confident if I "started fresh" with just the 512k sector drives, it will work fine. The question which remains is, if I replace a single 512 sector drive with a 4k sector drive, and then replace the 4k with another 512k, is there a way to remove said warning, or has something changed about the pool that cannot be undone ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
