Hi, I have a Newertech Guardian Maxiumus with 2x2TB drives in a RAID 1 on Macbook Pro 2011 13" running 10.8.4. I turned on the drive tonight and got the dreaded "The disk you inserted was not readable by this computer." I saw the "rebuild" light blink but the drive indicators did not go red to indicate which drive was dead. I tried Disk Utility, even downloaded and purchased Disk Warrior but DW doesn't even see the drive. I removed the drives and put them in a Black X USB docking station but the same error showed up. I finally ran Data Rescue from Prosoft and it has allowed me to copy files file by file/folder by tolder to a secondary 2 TB drive. Unfortunately it is going to take about 40 hours and I'm just wondering how Data Rescue is working and DW does not even see the drive. Do you know if there is any way to get DW to see the drive and get back the data faster? Do you know what causes this error? Could it be the Newertech Drive? I have the drive in a Sentry Fire safe and I was moving it earlier tonight on the ground. I hope that didn't cause any static buildup. Or maybe the Newertech drive sucks and caused an electric spike. I'm just trying to get to the bottom of this. I saw some people had luck with DW and so I spent $108.
