    For the past week every other day my network mapping to the nas200 is inaccessilbe. I cannot connect with the webinterface and cannot power off with the button.
    When I look at the leds, the HD leds are blinking alternatly.
    2 times I just pulled out the powercord and connected it again after a while.
    Then within 10 minutes I can connect to the disk again.
    But pulling the power cord is definately NOT the way and can corrupt the data.

    I have 2 1Tb WD HDD in RAID1 filled with 850Gb of data.
    Does anyone had this before and/or knows a solution?

    Can i pull out 1 of the disks, put it in a external casing and connect it to a windows 7 computer and read data?

    Your problem is probably heat-related; the NAS200's fan is notoriously under-dimensioned and your hard disks probably run hot and shut themselves down. I think the alternate blinking means that the processor has either lost access to one of the disks or is rebuilding the RAID.

    You cannot use a Windows computer to access the data because the NAS200 uses the ext2 (non-journaled) and XFS (journaled) file systems. A Windows computer won't understand those. You can connect the drives to a Linux computer that understands those file systems and the mdadm command, and access the data; if you don't have a Linux computer you can use SystemRescueCD which should automatically mount the drives.

    Hope this helps!

    Try to search Hiren's BootCD 11.0, it has a linux based file-recovery, it will help to access your drive. I used it to copy my internal HDD content to new NAS200 HDD! :)
