+Below are the steps used to successfully access the data using 1 of the hard disks.  The main internet links used to establish this procedure are [[https://www.experts-exchange.com/questions/26952383/How-do-I-access-data-on-a-Netgear-Stora-formatted-drive.html|How do I access data on a Netgear Stora formatted drive?]] and [[https://www.spinics.net/lists/raid/msg44459.html|Desperate: mdadm fails to assemble raid saying devices are busy]] (use 'next by thread' to see all the email discussion)
+This STORA appears to use a software RAID configuration and the data is formatted using the Linux XFS file system.
 The basic idea is to have a desktop PC running linux, such as 64-bit Red Hat Enterprise Linux 6 (RHEL6) or [[https://www.centos.org/|CentOS6]] which supports the XFS file system.  Power it off, and attach the STORA hard disk as a secondary drive (it uses a SATA connection).  Linux should recognize the hard drive and using the steps below will mount the drive.  Then the data can be copied off the drive, or rsync'd to a remote machine.

-The result shows what the active RAID1 device is, for example "md127"
+The result shows what the active RAID1 device is, as seen above it is **md127**.
 <code>
+# mdadm --stop /dev/md127
+mdadm: stopped /dev/md127
+</code>
+This stops the RAID device so you can act upon it.  Look for confirmation that it is **stopped**.
+<code>
+# mdadm --assemble /dev/md127 --run /dev/sdb1
+</code>
+This starts the RAID with 1 drive
+<code>
+# mkdir /stora
+</code>
+This creates a local mount point for the STORA drive you are about to access
+<code>
+mount /dev/md127 /stora
+</code>
+The NAS hard disk is now accessible in /stora.
+<code>
+cd /stora
 </code>
+View the files and copy them to another location, rsync is a good tool for this.
