Hi all, my computer has been acting weird lately and I couldn't access my dlink 323 nor could I access the config page.  i went to it and held down the power button to turn it off so I can turn it back on. but holding it down wouldn't turn it off. so I pulled out the power cable, then plugged it back in.  but then I still couldn't access it.  when I tried to access its config page, its now asking me if i want to format it and which raid do I want to use.  if I access it using its IP address, I don't see the volume I created.  did I lose all my data??? if so, can I get it back somehow?  the volume was configured in mirror mode.  someone please help.  thanks

update:  i went into the config page and it only sees 1 hardrive and the volume is "degraded".

How did you setup your disks, RAID 0, RAID 1, or what? 

If it was RAID 1 then you can try and recover your data by taking one of the disks and putting it into a USB/SATA caddy or using an adapter and plugging it into a computer that can read Ext2/3 formatted disks (use an installable file system with windows).  Also you may have to try the other disk if there are problems reading the first one - from your report that the RAID volume is degraded.

If the disk is readable you should be able to copy your data to another disk which will then be the backup you should have.  Replace the disk in the NAS and then allow it to rebuild the array if that option is offered, otherwise reformat and setup as necessary then restore from the backup you just made.

Hi, its setup as raid 1 (mirror).  right now as soon as I go to the config page, it asks me how I want to format the hardrive.  it only sees the one hardrive now.  I can access my nas using the IP address, but I don't see the volume I created.  somehow it got damaged.   so if I replace the bad hardrive with a new one, i don't think it will rebuild the new hardrive with the data that's already on the other good hardrive.    can you give me an example of something that can read the ext2/3 data?  is there a site where I can download a boot CD?    or is there an application I can install on my PC  and I connect my nas to the usb port or plug the HDD into the sata port?

No problem. Please post back and let us know how things turn out.
Good luck!

my pc may have gotten a virus.  can a virus wipe out the volume on a nas plugged into the router?

[JavaLawyer]

If the client PC with the virus has write access to the NAS, then the virus can delete/damage files if it's designed to do so. Since your DNS-323 is configured as RAID-1, any changes to HDD1 by a virus will immediately propagate to HDD2.

A RAID-1 array provides redundancy, but is not a backup: DNS-323 - Data Backup vs. Redundancy

thanks for the link.  I read it and agree totally.  I wasn't thinking beyond HDD failures.  I think next time I will use two seperate volumes and make sure both volumes are the same manually intead of using raid0. 

let me ask another question.  the config page of the dns323 sees only one HDD and in the logs, it said there was a HDD failure.  the manual says that if there is a HDD failure, the HDD light on the nas will be amber.  but both lights are blue.  so what do you make of that?

hi, when I got home from work, I reseated both HDDs and turned the nas back on.  now my windows 7 PC can see the raid 1 volume, but when I try to access it, it doesn't work.  I went to the config page and it gave me the window where it thinks there is a new hardrive and it says "Click 'Next' to begin formatting the replacement drive. Re-synch will take place after the restart" and has the a checkbox that says "Reconfigure to RAID 1".   I can click Next or Skip at this point.  If i chose to reconfigure as raid 1, i wasn't sure if it will format everything and erase the data, so I chose skip and it brought me into the config page.  it now sees both hardrives, but it still says the volume is "degraded".  If i were to click the "Reconfigure to RAID 1" and click Next, do you think it will copy over the data from the good hardrive to the other instead of erasing everything?

Hi, I installed Ext2IFS and plugged one of the hadrives directly into my PC.  I went into control panel->Ext2IFS and it shows the hadrive with 3 partitions. I chose driver letters for each of those partitions.  then went to My Computer and I can see the drive letters.  but when I double click on any of them, it says "the disk in drive P is not formatted. Do you want to format it now"?  i chose no.  what do I do now?  is it possible I used ext3 for my nas and this software is not able to read that?  please help!!

thanks

A part of the problem you are seeing may be the fact you have the drive plugged into a windows PC when it boots.  Windows will try and assign partitions to the drive before the IFS is loaded and operational.

When we did tests on our systems we always used a USB/SATA adapter and plugged it in after the PC was running.

The other thing you could try is to boot your PC from a live Linux CD.  This should allow you to see external USB drives and copy the data, if necessary, to the PC hard drive.

i ended up installing http://www.ubuntugeek.com/how-to-read-ext3ext4-linux-partition-from-windows-7.html and i was able to easily backup my data.  thanks.

is it a bad idea to keep a nas in your basement where it might be more humid than the rest of the house?
