Count me in. I would love to give it a go.

In general, be very careful on typing.  Mistakes in entering some commands can have very bad consequences.  The commands I'm giving you should be pretty safe though.

You'd first enable ssh via the web ui (system->settings->services).

Then confirm you can log into the NAS using it.  On a Mac you would do that with terminal.  Enter

ssh root@nas-ip-address

using the real NAS IP address of course.  When prompted for the password, you use the NAS admin password. 

After you log in with ssh, you'll need to re-insert the new disk.  Wait about 5 minutes after that for the ReadyNAS software to test it. 

Then start with this command:

lsblk -o name,model

This will list all the disks and their partitions.  One of my NAS shows this (yours will have similar information)

NAME      MODEL
sda       WDC WD100EFAX-68
├─sda1
│ └─md0
├─sda2
│ └─md1
├─sda3
│ └─md127
└─sda4
  └─md126
sdb       WDC WD100EFAX-68
├─sdb1
│ └─md0
├─sdb2
│ └─md1
├─sdb3
│ └─md127
└─sdb4
  └─md126
sdc       WDC WD101EFBX-68
├─sdc1
│ └─md0
├─sdc2
│ └─md1
├─sdc3
│ └─md127
└─sdc4
  └─md126
sdd       WDC WD100EFAX-68
├─sdd1
│ └─md0
├─sdd2
│ └─md1
├─sdd3
│ └─md127
└─sdd4
  └─md126

Also, enter this command to see what (if anything) is syncing:

cat /proc/mdstat

Again, one of my own NAS shows this:

Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md126 : active raid5 sda4[0] sdd4[3] sdc4[4] sdb4[1]
      11717352576 blocks super 1.2 level 5, 64k chunk, algorithm 2 [4/4] [UUUU]

md127 : active raid5 sda3[5] sdd3[7] sdc3[6] sdb3[4]
      17567012352 blocks super 1.2 level 5, 64k chunk, algorithm 2 [4/4] [UUUU]

md1 : active raid10 sda2[0] sdc2[3] sdd2[2] sdb2[1]
      1044480 blocks super 1.2 512K chunks 2 near-copies [4/4] [UUUU]

md0 : active raid1 sda1[5] sdd1[7] sdc1[6] sdb1[4]
      4190208 blocks super 1.2 [4/4] [UUUU]

unused devices: <none>

Copy/paste the output of both of these commands in a reply, and I can give you some next steps - including how to run the long smart test on the new drive.
