    Recover file deleted from NAS?

    I mistakenly deleted a file from my NAS - Synology DS210j.
    I hoped to use 'recuva' but the NAS unit, though visible, can't be accessed in recuva.
    I took out one of the RAID 1 disks from the NAS, installed it directly to my PC (Win7). Using Speccy, the disk is visible, contains 3 partitions (2.37Gb, 2.00Gb, 461Gb). But no drive letter, so unreachable within Windows. So recuva again not usable.
    I contacted the professionals - way too expensive.
    Where is the way forward here, please?

    Did you try to assign a disk letters to the partitions using Disk Management?

    Yes, I did try, using Disk Management - not allowed.

    Well, you're going to need something that can look at the file format the disk is in first and foremost I would think, and then be able to look for deleted files specifically. I'm guessing that the file system is EXT3 or EXT4. Found one program on sourceforge that might work if that is the format and nothing too proprietary is added by Synology.
    Seems to me you'll need a LINUX install of some sort and some command line learning if such is not your forte already.

    The NAS may use it's own format, making recovery impossible. I would ask the NAS manufacturer first.

    cheers, Paul

    I added a Ubuntu Linux PC to the network. That gave me the same management access to the NAS that I have with Windows.
    The Sourceforge program (5 star lounger advice) looks a bit scary with my skills.
    Eventually I got lucky and found a not too old backup copy elsewhere on my system, so it's no longer urgent.
    So far I haven't been able to get any useful advice from Synology.

    Apparently over on the Synology forum they say you can activate the recycle bin on the NAS even after you have deleted the file:

    But probably more helpful is the synology advice to use an Ubuntu Live CD (but I would guess you will also need a Linux undelete program like extundelete, foremost, or similar):

    http://www.synology.com/support/faq_...g=enu&q_id=579

    There appears to be a lot of links that come up when googling "undelete synology nas"

    FWIW, although not directly related to the problem with the RAID NAS, I recently had my NAS go south. This was a standard USB 2.0 WD 1.5 Tb drive hooked into a Cisco EA4500 router using the NAS hardware in the router. The router took a hit during a thunder storm, even though attached to a UPS, and lost the NAS definition which would not restore from a saved backup of the router configuration file. However, just plugging the USB HD directly into a computer revealed that all the files were still in tact which made recovery a snap. Hope this may help someone else reading this thread with a slightly different problem.
