Title: Are my files still intact?
Post by: DavidLPeng on March 05, 2009, 10:22:26 PM
I just purchased a new 1TB hard drive to compliment my existing 1TB hard drive (with files) currently residing in DNS-321 slot 2. I inserted the new drive into slot one without thinking and power up the device. Then when I got into the web UI, it ask me to reformat the drive in slot 2 and configure RAID type. Since I want to run RAID 1, I power down the device and swap the location of the drives. To my horror... my files are now gone missing. So I power down again and went with the original configuration. I leave the new drive out and just set it aside.

When I power back up, the hard drive is blinking but I still have no access to my files. Will I ever see my files again? Is there a way to recover it?

What is the suggested way to add 2nd drive and to configure RAID 1 without loosing my data?

Thanks.

Okay... so when I soft rebooted from the web UI... (with only one drive as the original config...); I am able to access my files again. That's a big relief!!! Man.. that scares the heck out of me .. I can't afford to lose the data in it. :(

losing your data? I recommend a backup scheme too. raid or no, your data can still be lost for any number of causes....

Right.. RAID 1 doesn't guarantee but I better off with RAID 1 than just storing those data in a single hard disk. Anybody doesn't agree? ;)

The only advantage, I can see, to RAID1 (over a single hard drive) is that your data
will remain available in the event of a single hard drive failure; otherwise RAID1 has
the same risks as a single hard drive solution.

The advantage of RAID1 is the reduced down time when a disk fails - the disadvantage of RAID1 is the loss of 50% of the available space

before switching your device from single drive to raid I'd suggest taking a backup somehow.
