Help formatting 2.5TB USB drive for backup
Hi all-
Apologies, have studied the archives but can't fix my problem
I have an external WD USB 2.5TB Hard drive, and wanted to dump my entire NAS to it.
I have:
ReadyNAS NV+
RAIDiator 4.1.8 [1.00a043]
Online, X-RAID, 4 disks, 54% of 2771 GB used
I had some trouble using the Mac Disk Utility to format the disk, but eventually was able to format it with a single partition with a Master Book Record partition map scheme. (I'm not even sure what this is, but in the archives I learned that I needed to do that to use EXT3.)
Description of the drive from Disk Utility (which cannot read the drive due to EXT3 format):
Disk Description : WD Ext HDD 1021 Media Total Capacity : 2.5 TB (2,500,493,049,856 Bytes)
Connection Bus : USB Write Status : Read/Write
Connection Type : External S.M.A.R.T. Status : Not Supported
USB Serial Number : 574341575A31323139393030 Partition Map Scheme : Master Boot Record
I have set my ReadyNAS up for Fast USB.
When I then go into frontview and format the drive in EXT3, it continues to show up as 196GB
Any help or suggestions greatly appreciated.

- itbedaveAspirantI'm going through this right now. Did you ever come up with a solution?
- you can not.
Over 2tb drives require GPT, not MBR.
Sparc devices like NV+ do not support GPT.
You must connect your usb drive to a PC/MAC then backup your nv+ over the network.
Or use a regular 2tb drive. - jhannahAspirantYep, I solved it!
I sold my NV+ on ebay and bought an Ultra. Which then worked without a hitch. - itbedaveAspirantNow I'm understanding why Newegg had the Duo on sale. Guess I'll be sending mine back. :?
- The duo/nv+ v2, which was recently announced, supports GPT and large drives, you should see if you can find one of those for a good price. Or go with an ultra 2 or 4.
- fixmacsGuideOh... I recently bought an NV+. How do I know which version I purchased? If I version 1, is it possible to use multiple 2TB USB drives to backup the NAS?
- mdgm-ntgrNETGEAR Employee RetiredThe v2 was released for sale beginning November 13th 2011. Units sold before this time will all be v1.
v1 units will show a firmware version of 4.1.x in the Info (far right) column of RAIDar and have a web-interface that looks like this: http://www.readynas.com/simulators/frontview
v2 units will show a firmware version of 5.3.x in the Info (far right) column of RAIDar and have a different new dashboard web-interface.
The v1 is the RND4000-100 and the v2 is the RND4000-200
With the v1 you can use multiple 2TB USB drives. Create multiple backup jobs with each backing up <2TB of data.
