If you are the original purchaser, then check the warranty status ASAP. The hardware warranty should be 5 years.
FWIW, your NAS is called a "v1" here. There's a newer v2 that uses an arm processor. More strictly you have a "hardware version 3" v1.
If it is not covered by warranty it is possible to replace the PSU, there are threads here on the subject. The cheapest way involves modifying the pinout on a stock supply.
On migration to a new NV+ v1:
- install a scratch disk in the new unit.
- after it installs, upgrade the firmware
- power down the NAS
- install the original disks (keeping slot order)
- power up
The NAS will upgrade the disks to the current firmware when it boots for the first time.
If you skip the scratch disk step, then the NAS will downgrade the disks (since you upgraded the firmware at least once after you installed it). It's safer to upgrade very old firmware than it is to downgrade. So it's best to upgrade the replacement NAS before migration.
Hello StephenB,
Many thanks for the prompt reply, it is greatly appreciated.
I have checked the warranty on the Netgear website (by typing in the serial number) and it appears that the warranty was only for 3 years (expired in 2015), and yes I'm the original purchaser.
I have ordered a replacement power supply online, but it is a few weeks away as it is coming from overseas, and I need to get the data accessible again as soon as possible.
Thanks for clarifying the exact model, and for detailing the steps to setup the 2nd NAS.
Two questions on this process,
- My current drives are in Slots 1 and 2 (going from the left most side), do you set the scratch drive up in Slot 3 or another slot (i.e. Slot 1) ?
- After you setup the scratch drive and upgrade the firmware, and then power down the unit, do you remove the scratch drive before installing the original drives (in their original slot order) ?Another question, say I was deeply concerned about loosing my data and only wanted to risk one drive in the migration process (leaving the remaining drive as a last ditch recovery option via an alternate method).
- Is it possible to set up the second NAS drive as you have detailed in your reply, leave the scratch drive in place (say setup in Slot 3), and move one drive only (say the drive in Slot 1, which from memory is the 'primary' drive in the existing RAID mirror) to the new NAS drive ?
- Would the two drives sync successfully without any data loss, or would the Slot 3 drive assume it is the 'primary' drive and overwrite the migrated drive ?Just trying to understand how the process could work if you were trying to limit the potential for data loss.
Thanks again for your assistance.
Regards,
GROn the scratch disk -
- you put the scratch disk in slot 1 with NO other drives
- after the install/firmware upgrade you power down the NAS and remove the scratch disk.
- then migrate the original disks, preserving slot order with the NAS powered down.
- Then finally power up.

No, doing that would wipe disk 1.
A newly inserted disk is ALWAYS synced to the drive(s) already installed, so anything on the newly inserted disks is wiped.
What you could do is install only disk 1, and boot up. I don't see that as safer though, since if there is a disk 1 problem when you hot-insert disk 2, you'd lose all your data.

If you only have two disks installed (XRAID or RAID-1), then one approach is to connect disk 1 to a Windows PC, and install rlinux-for-windows. That should be able to read the disk, so you can copy the data off.
Another approach is to use a disk cloning program that supports sector-by-sector copy. Clone disk 1 to a new disk, and then set disk 1 aside. When you migrate to the new NAS you can migrate the cloned disk 1+ the original disk 2.
If you don't have a backup plan in place for your NAS, I suggest taking care of that after you migrate to the new one.
Hello StephenB,
Thanks again for your prompt reply, and clarifying how the mirror process works when migrating single drives at a time.
I'll follow the instructions as per your previous posts and see how I go.
I do have a backup strategy in place, but like always, failures seem to occur out of the blue and at the worst possible time !
Thanks again for your help.
Regards,
GR
