Ok this is weird
I have a ready nas
2 x 2tb drives hang of it
on one of the 2tb's i had stored all my movies
I had trouble of late with the drive showing
So i took it of nas and plugged int another computer
The drive is showing 'Unallocated  space 1.8tb" that means the drive is blank right?

Please tell me I am wrong ...2terabytes of movies for gods sake!!!

The drive is part of a raid array, be it hardware or software.

You can't take it out of the NAS and view the contents of it on another PC.

Generally RAID1 you can just take it out and put it somewhere else. Depends on the formatting/partitioning though.

I don't think you can assume any RAID level. It could be JBOD too. We don't know what sort of NAS he has (sorry about rhyme).

He said he had the media installed on one of the drives.

I do agree that you can't take the drive out and expect to view it on a PC.

It is likely in some sort of Linux or proprietary format.

It is probably best to try and diagnose the problem by keeping the drive in the NAS.

If the drive has problems spinning up, then it is quite likely a hardware problem.

If you can get the drive to show again.. then make a copy ASAP!

Otherwise, I hope you have a good backup.

Back to ripping your DVD / Blurays I guess :(




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

Thank you all
just back to this question first

The drive is showing 'Unallocated  space 1.8tb" that means the drive is blank right?

This does not necessarily mean the drive has lost all its data?

Without knowing a) what NAS you are using and b) the RAID level and/or drive format any response people should be regarded purely as speculation, as it's impossible to offer any advice without knowing this critical information.

All that could mean is that Windows does not recognize the file system on the drive. THe positive thing is that at least Windows recognizes you have connected a drive (so the drive logic board appears to be fine).
If it was in a NAS appliance, there is every chance that appliance uses a proprietary File System (so not NTFS or FAT32, which are the most common WINDOWS files systems, there are lots of others).

Apart from data recovery people, your best hop is to put the drive back in the NAS and hope it comes back up (then back it up).

The partition is likely in a Linux format.

You could try loading an EXT file system driver that lets you view Linux partitions.  I have done this before to recover files from a failed NAS.  No harm in trying.

After re-reading the original post.. I see trhe term 'readynas'.

I assume that means you have a netgear NAS.

In that case, have you done what the following link suggests?    https://www.youtube.com/watch?v=ipXO2J1DGz0

gnfb,

   As others have indicated, your NAS storage unit contains its own Operating System ... usually a variant of Linux, and in the case of NetGears' ReadyNAS I think it is Debian.  Think of your NAS unit as being a mini computer all by itself.

The in-built Operating System also has an interface that can be used to emulate your computer's Operating System (be it Win or Mac for example), which is why we can see and use the drives just like the ones inside our computers.  However, when a NAS drive is removed from it's device, then it cannot be fully seen or used by those other Systems.

Best put it back in the NAS device and see if you can see/use it again ... the interface may even have some recovery options.

Also try Disconnecting and then Remapping the drive as sometimes I've found that these can come undone or confused.
