Using it, you could leave the second drive plugged into another computer, but it would stay sync'd to the drive in the first computer. It's not quite what you asked for, but it might solve your problem.<div><br></div><div>Scott<br><br><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"Alex Carver" <agcarver+ale@acarver.net><br><b>To: </b>"Atlanta Linux Enthusiasts" <ale@ale.org><br><b>Sent: </b>Thursday, February 12, 2015 4:42:04 PM<br><b>Subject: </b>[ale] Mirroring drives without RAID<br><br>Got an unusual question from someone at work.
