Hi,
I am not sure who told you that resetting your 325 would reformat the drives, but this is bad information. If you read in the manual, it will confirm that this is wrong information. Unless there is something seriously defective with your unit, this should never happen. I have personally reset the device several times and never lost data. Some of the configuration information will have to be reentered including the password, but that is it. What you will be able to do is go into the configuration and setup the IP assigned to the unit as static but the better way is to go into the router's settings and give the 325 a static or reserved IP address. This way it should not change. As far as remembering the password, write it down if you have to, but after you reset it, user is "admin", no quotes and the pw is left blank.
