Case Number: 17655849 NV+ Booting... Found Bad Disk
This is what I submitted to technical support about 30 minutes ago. I am copying here.
Hi There,
My NV+ (RND4450) became unresponsive over my network today. I attempted to power down the unit via the power button on the front panel (all drive lights were lit). No response via the power button. I disconnected the power cord then reconnected. The device would not power on. I suspected that the power supply had failed (this has happened on other units that I have used at work in the past). I replaced the power supply and attempted to power on the unit. The unit began to boot but displays the message "booting... found bad disk". I hear the disks being accessed but there has been no change for well over an hour. Raidar will not connect either.
I am sure that everyone says the same thing but it is true here as well. I do not want to lose the data on this device.
What is the next step that should be taken. I have read hundreds of posts in the forums with people removing the drives and rebooting all while other forum members state to contact technical support before doing anything else. I am taking the conservative approach here and I am contacting technical support first before attempting anything.
Any assistance that you could provide would be greatly appreciated. Ten years worth of faimily photos, music and movies are located on this NAS. I can not afford to loose this data.
Thanks,
Keenan Ball
Since writing to support I have not powered off the unit. I am awaiting a response before attempting anything else. The LED in the power switch blinks 3 times, then the activity light blinks for a moment. This repeats over and over.

- Best to wait for tech support to provide assistance.
Do you have one or more SATA ports in a PC you could hook the drives up to, to test using vendor tools?
If so, you could power down the NAS, remove disks (label order) and test them using vendor tools (run both short and long test). If just one of the disks is bad, assuming you're not using RAID-0 the system will likely boot with the remaining disks in the NAS (same slots as they were before).
In future I suggest you backup your data particularly your family photos. Important data primarily stored on the NAS must be backed up. - @MDGM Thanks for the reply.
I'll wait to do anything (even power down the unit) until I hear from tech support.
I have a eSATA port on my laptop but no cables and adaptors to connect to a bare drive. I'll see if I can find some locally tomorrow. I am fairly certain that I set up the NAS using RAID-X (default) a couple years ago. I hope that will be the saving grace here. I used the NAS just last night without issue. I would be surprised if there was more than one drive with an issue. However, nothing is impossible.
Understood about the backup. The problem has been the frequency of the backups (which has not been very frequeny this past year). Trust me. I am kicking myself...
What do the tests performed by the vendor tools do? What sort of info is provided to the user?
Thanks,
Keenan - You really need an internal SATA connector. These tests, typically non-destructive (should alert you if you try to run a destructive test) check the drive to see if has problems with it and should in most cases detect a problem disk.
However if connecting to internal SATA port in PC isn't possible, tech support should still be able to help you determine which disk is bad.
One method I think is that when you power on the NAS it should briefly show in RAIDar (http://www.readynas.com/downloads). Hover your mouse over the disk LEDs and look for ATA errors. - Over the past couple minutes the NAS has managed to boot on its own (again I have just let it sit with the "Booting... Found Bad Disk" message). I have been able to access Frontview and have looked at the logs. This is what I found:
From today --
"A SATA reset has been performed on one or more of your disks that may have affected the RAID parity integrity. It is recommended that you perform a RAID volume resync from the RAID Settings tab ( accessible in the Volumes page => Volume tab in FrontView ). The resync process will run in the background, and you can continue to use the ReadyNAS in the meantime. "
From yesterday --
"Reallocated sector count has increased in the last day. Disk 1: Previous count: 72 Current count: 73 Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk."
I have been able to access my files and I am presently backing them up to a USB drive.
Is there anything special required in swapping in a new Disk 1?
Thanks,
Keenan - First backup your files. Then if you are confident that disk 1 is the bad disk, remove it (this can be done while the NAS is on) and add the replacement (also can be done while the NAS is on).
- Keenanball - even if you were able to find an SATA to eSATA cable, that is just the signal cable. You would still need the power connection. mdgm's advice is sound. Now that you have access to the volume, perform a complete backup of all your critical and important data. This is a good idea anyway. The reason is if when you replace the drive and it is accepted by the NAS and a resync starts, this puts a long continuous strain on the drives (constant activity for 8 to 12 hours or more) during which if you have a weak drive, it could fail and then you have the real risk, indeed likely hood of data loss.
