Unable to copy from NAS Drive

I have a D-Link DNS 323 NAS with a 500Gb and a 1TB drive. I am trying to copy from the 1TB drive to an external USB drive. The format on the NAS drives is FAT.

What happens is that when I start copying, the process starts and then errors out saying 'cannot find drive". When I go to the mapped drive letter in "My Computer", the contents are gone. If I reboot the NAS, I see the contents for a little while and then they are gone again.

I tried pulling the hard drive and connecting to a USB to SATA adapter and my computer wants to format it.

I am running XP SP3 and desperately need the contents of this drive. I was able to copy a few items but when I select anything large I get the error. I also have another NAS and every now and then I get the "disconnected Network Drive" message when I open my computer.

I am aware of the 4GB file size limit and have no issues copying large files from the 500GB drive on the same NAS!

Any suggestions will be appreciated!

You have bad info.  There are 2 partitions ... the first is for the embedded LINUX O/S.  The 2nd partition, where your data is, is formatted via one of the LINUX file formats . I think XFS, but don't know.

You are wasting your time going down this path.  No, you are risking further data loss.   At this point, you need to have skills in hardware recovery and decent LINUX skills to determine file system parameters and likely create a custom kernel config ... assuming the HDD is even good.   You need to either take it do a data recovery specialist, or hire somebody to do it for you.  There are no consumer-based products that you can use to get this going.
Sorry

What if I pull the drive and mount to a linux box? Do you think that would do anything?

Get a Konppix or Ububtu live CD/DVD/USB-stick and boot from it.
Check if you can mount the data partition of your 1TB drive and copy to a backup partition or drive.

Do NOT try to mount the disk in RW mode, and make sure you disable any automatic fsck.  You have to figure out the type of file system and appropriate parameters.  I have not been  inside of this one, but be prepared to have to gen a custom kernel, and build the XFS loadable file system module (which is rather common on NAS boxes)

Sounds complicated...I've only used Knoppix for NTFS file recovery. Is there any reading material you can suggest? My Linux knowledge is minimal at best!

DonConsolioCommented:
Knoppix mounts any drives read-only by default.

You have to enable read-write (for your destination partition) in the right-mouse-button menu
or by command line ( e.g. sudo mount -o remount,rw /path/to/readonly-mounted-filesystem)
or save to a network share or ftp server.

No, it is just one of those experience things. This sort of stuff isn't written down as conventional wisdom is that anybody that needs a step-by-step doesn't have the foundation necessary to do the job.  Lets' just wave a magic wand and assume that you are an expert with LINUX....   You still have to deal with assessing HDD health and doing a binary image when I know you are going to have some unrecoverable read errors.  So when you get the first one, what do you do?  How do you determine if it is in a file or free area, or a filesystem header?  Do you have ability to assess if the HDD has a problem that is so bad that doing an I/O intensive clone will crash the HDD permanently ?
