I'm having a pain in the database in that my 4-year old WD WorldBook dual-bay,  2TB NAS enclosue became unavailable to all my computers.  Given the RAID 1 configuration, I believe that the problem is the enclosure itself rather than both drives at the same time.  I purchased 2 external 3.5 drive enclosures and installed each drive from the NAS enclosure in each new enclosure.  This isn't a new procedure in that I can count 8 of the external enclosures around my three computers right here.

 

Each 3.5 enclosure started fine and when attached to any of my 3 computers, 2 desktops and 1 laptop, the normal beep signifying new hardware sounds but the drives aren't visible via Windows Explorer, Device Manager, DOS, or PowerDesk.

 

Computer attributes follow.

1 desktop, Win7 Pro, 8 GB memory

1 desktop, XP SP3, 3 GB memory

1 laptop, Win7 Pro, 16GB memory.

 

All processors are fast enought to support the external drives.

 

In researching new NAS enclosures, it seems that the ones I was able to find with any installation details would automatically erase all data from any hard drives installed as part of the setup.

 

I still need to test the newly purchased external 3.5 enclosures via my router or to install the hard drives physicalkly inside one of the desktops.  I thought I'd ask if anyone has any suiggestions before leaping into these alternatives.

 

Right now I'm backing up the other NAS device on my netwoirk so I don't want to do anything on the network until it's done as I've already invested enough time such that I don't want to start over.  I'd also need to replace the hard drive into one of the enclosures as I removed both when none of the computers could find them.

 

Thoughts?  Thank you.

do they show up in Disk Management (from the Run box diskmgmt.msc) as raw or unallocated ?

if they are there http://findandmount.com/ may be able to find the partition

Thank you!  I had totally forgotten about diskmgmt.msc as it's been many years since I used it.  I didn't know about Find and Mount.  Both drives are fine according to diskmgmt and I'm running a scan for each hard drive now.  Thank you again.

Well, it turns out that WD uses a proprietary file system that Find and Mount can't see. Although the Disk Management Utility sees them, its capabilities are limited so I'm left with exploring other options. It seems that Xubuntu has the ability to get the data.

Hi,

 

Warning do not let Disk management do anything to the drives. That could cause data loss.

 

I may be way off here, But I suspect that the World book does not use a Windows format on the drive. I suspect a Linux format for the drives. I will explain why. If they use a Microsoft Windows format they would have to pay a license fee to Microsoft. Linux would be free.

 

From Here: http://en.wikipedia.org/wiki/Western_Digital_My_Book

This drive runs BusyBox on Linux on an Oxford Semiconductor 0XE800 ARM chip which has the ARM926EJ-S core. In addition it uses a VIA Cicada Simpliphy vt6122 Gigabit Ethernet chipset, and a Hynix 32 Mbit DDR Synchronous DRAM chip. The webserver is the mini_http server, although older "bluerings" use Lighttpd. The drives of the World Edition are xfs or ext3 formatted, which means that the drive can be mounted as a standard drive from within Linux if removed from the casing and installed in a normal PC.

 

 This wikipedia article agrees with Linux.

Thank you Roger.  I agree and haven't done anything with Disk Management other than to look at the drives.  This whole things is just a pain in the database that's taking time.  I still have various alternatives to try.  I just prefer to start with the simplest and easiest first.
