Re: Corrupt Boot - "Err: Could not mount root RAID d"

For most users, the best RAID format is to use the default XRAID.  That can be expanded w/o data loss, and it has protection for a single disk failure.

 

If you want maximize storage space and don't care about expansion or protection from a disk failure, then the best option for that is to use flexraid and create one volume for each disk.  

 

To do that, you need to start over and set up the NAS again.  Remove all disks but the first, then do a factory reset using the boot menu.  You have a 10 minute window to configure the system for flexraid using RAIDar.

 

Details are in the hardware and software manuals for your ReadyNAS here: http://downloadcenter.netgear.com/en/product/RNDP4000%20(ReadyNAS%20Pro%204)#searchResults

Your NAS doesn't use NTFS.  It uses EXT.  When you insert a disk into the NAS, the data on it will be wiped.  

 

The NAS doesn't let you create a "library" of hard drives that you can insert/remove on demand.  The disks need to remain in place after you create the volumes.

Buying a second hand unit is risky and also the warranty and support is for the original purchaser from an authorised reseller only.

 

Which model is this?

You possibly could try USB Boot Recovery

Re: Corrupt Boot - "Err: Could not mount root RAID d"

Which model and which firmware?

I understand you now have reset it successfully but don't like it that it has created a single volume C using all your disks?

Re: Corrupt Boot - "Err: Could not mount root RAID d"

because I just only want to make a big storage with 4 hard drives ( has data inside ready ) , Like plug & play & when i put in a hard drive ( with data inside ) I don't want it Resync or Format it whatever ?. Just put in & read the data inside (with NTFS format).

can i do that with Flex-RAID-0 ?

Thanks
