The replacement drive has some data on it, what is the best way to format it before installing

Again, you don't want to format it. Rather you want to unformat it.

With windows, right click on computer and select manage. You can then right-click on any "volumes" shown in the windows disk manager for the drive, and delete them.

Or use a vendor disk diag (lifeguard or seatools), and use the test to zero the drive. There's a quick-erase test in one of them (I forget which) that zeros sectors at the beginning and end of the drive. That will wipe the partition info, so the NAS will see an unformatted drive.

Check what NV+ version you have first:

Do you have a backup?

Have you received any messages about disk errors?

How many disks are in, what make and what size are they?

Were you using Xraid?

Do you know what firmware was on the device?

The first step in diagnosing this will probably be to test all the disks. To do this you will need to power down, remove the disks, label them according to slot number, then hook each one up to a PC and test it using vendor tools.

Do not power on the unit unless all the disks are back in, in their correct slots.

  It's a NV+ v2, 8TB using 3x Samsungs & 1 WD, all 2TB, had no reports of disk errors, the last message was the disks spinning down, but the NAS wasn't accessible over the network, Don't know what version of firmware is installed but think it was the last one and it is either RAID 5 or XRAID, after restarting it stays on booting for about 15 mins and then goes onto the message Checking boot FS and no IP is displayed below.

    Did you use the guide in the link to determine the model you have? The v2 on the unit is not enough to determine the exact model.
    
    Do you have a backup?
    
    Is the device still under warranty?
    
    How long have you left it with the checking fs message?
    
    I would start by testing all the disks using vendor tools (Seatools may work with the Samsung drives and wd lifeguard). I think there may be a Samsung tool but you'll have to find it.
    
    Booting using the skip volume check boot menu option is something you could try too, but if you have no backup this carries some risk of data loss.
