Hi all,

To get to the quick. Our DNS-320 is not recognising any of the three HDs we've been successfully using in rotation for about three months under a mirrored Raid1 configuration.

Sure, the data partition appears to be ext3 but (I'm assuming) the Raid management means the partition contents are stored in regular 4096 Byte files (presumably blocks) of the form:-

$BlockBitmap.0000.bin, $BlockBitmap.0001.bin,  $BlockBitmap.0002.bin etc.

We've tried examining the partition using advanced tools including R-Studio but this is all we see. Reading around it looks like it should be possible to mount the partition as a degraded Raid1 array and copy data from it. Can anyone provide, or point to a clear Howto on the steps required to do this under Linux? I don't want to risk the data further by dabbling around with Raid tools such as mdadm so a simple step-by-step for temporarily mounting an orphaned Raid partition would be excellent.

BTW, the sticky data recovery thread in this forum section does not help. It just confirms that the native format of the NAS data partition is ext3 and mountable. I know that, but need to resolve the data into a readable directory structure of files.

Thanks in advance.

hi,

not sure if this will help, but i successfully tested coping files from my drives using this tool

worth a shot.

According to the OP, I believe he already tried the apps in this sticky thread: DNS Data Recovery (Windows PCs). ext2read is already listed.
