 If in any doubt about something (e.g. a dataset has two project codes), contact Gary.
 
-== Permissions fixing ==
-Ensure permissions on the SATA disk are correct and all files readable ("chmod a+rX /mnt/satadisk" as root)
+== Mounting the SATA disk ==
+To mount the SATA disk, put it into the computer. Then ssh onto the machine. Run `dmesg` to show information on the device names, the kind of thing we would be look for is:
+
+mptsas: ioc0: attaching sata device, channel 0, id 1, phy 1
+
+scsi 0:0:1:0: Direct-Access     ATA      ST3500630AS      E    PQ: 0 ANSI: 5
+
+sd 0:0:1:0: [sdb] 976773168 512-byte hardware sectors (500108 MB)
+
+sd 0:0:1:0: [sdb] Write Protect is off
+
+sd 0:0:1:0: [sdb] Mode Sense: 73 00 00 08
+
+sd 0:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA

+
+sdb: sdb1
+
+where the name of the disk is sdb (sata disk b) and the partion is sdb1. SATA disks will be 500GB in size.  If paranoid and want to look at a time stamped version run 
+ `sudo less /var/log/messages`. 
+
+To mount the disk use command `sudo mount -o ro /dev/sdb1 /mnt/tmp`. This will mount it read only.  Then check the data looks ok.  Then remount the disk using `sudo mount -o remount,rw /mnt/tmp` to make it read/write and run the commadn `chmod a+rX -R /mnt/tmp'.  Then re mount the SATA back as read only, `sudo mount -o remount,ro /mnt/tmp`
