A recent power outage knocked out my Linkstation Pro Duo 2TB v3 (configured with RAID1 mirroring)
I used the TFTP procedure to boot (LAN not WLAN!), and reloaded the firmware v3.
The web GUI then appeared in Japanese - I have switched this back to English.
However, I cannot see any of my data, and the webGUI reports the drive as empty.
Needless to say I didn't expect to lose my data (or "firmware" for that matter) from this RAID configuation due to a simple power outage. Am I missing anything?
I just experienced the exact same thing, power out, TFTP, reload the firmware, japanese nad everything is gone. :manmad:
The drive was configured as RAID1 before and now it apears to be RAID0, needless to say I'm more than pissed off as this was the data storage and backup for a large project...
my trust in Buffalo linkstation is gone but would be very happy for a chance of saving the data...
When you loaded the firmware did you force the update? Take me through how you updated the firmware. Also understand that any electronic device can fail as a result of a power outage. The best thing you can do to prevent data loss is to back up the data elsewhere as well.
Yes the update was forced, it was the only way of getting it done...
The problem with backup was that this was the backup...
Did you check the option to rebuild partition table? That will delete that data on the unit. If you did not, I doubt that the update itself caused the data loss. It would most likely be file corruption.
The procedure was
So you didn't actually perform the force firmware update?:
If this is your backup then why don't you just get your files back from the original source?
I actually did do the force update as it would not work with the IP address the NASnavigator showed.
I did configure the INI file with the debug option and gave the 192.168.11.150 IP address, the update went almost through but it complained something about not being able to verify the update as it could not access the NAS after it was loaded.
This was the backup and a repository for quite a bunch of files we have in our project. As it was the INCREMENTAL backup source we no longer have the possibility to go back to a certain date which is a much wanted feature when doing configuartion testing on large systems.
Is there any way of rescuing the data or does the update actually reformat/repartition the drive as it appears to have done?
If you selected rebuild partition table then there is not too much can do as it does a complete format. You can try contacting a data recovery company (like drivesavers, www.drivesavers.com).
Even if you were doing incremental backups it is still a good idea to back that up (if past versions of files are still important to you). As with any storage device the only way to ensure the sanctity of your data is to have it backed up in multiple different locations. I believe the IT standard is 3 backups? I could be wrong on that number..
My steps the same as Drizzle's. I'm pretty sure I didn't check the rebuild partition table option. Surely a power outage wouldn't destroy _all_ the data on _both_ the drives? The drive wasn't in use at the time - I've noticed the drive seems to click away even if nothing else is plugged in on my network - any way to get it to power down / wake-on-LAN - ie get the heads away from the disc?
I guess we are saying my back up is lost...
No I did not select rebuild the partition tables.
What I selected was exactly as in your description
Apart from the IP address of course.
Driz:
Most liekly file corruption. You can try recreating the share folder that contained the data, but that is about all.
INL:
If it is clicking it is probably a bad HDD. The rest of the data on the other HDD is most likely in tact. Are you still within your 1 year warranty? Also you say you can get to the web interface? So is everything working (except for the data loss)?
By clicking I meant the kind sound a drive makes when reading/writing. The NAS is only for my home backups/media server, so when PCs, PS3 etc are switched off, there's nothing else on the LAN so I was surprised to hear it whirring and reading/writing when no chance of anything accessing it. After TFTP/firmware update/switch to English everything seems to be fine - just no data...
"Surely a power outage wouldn't destroy _all_ the data on _both_ the drives"
It actually could in several different ways. A power outage can cause motherboard, fan and power supply damage. Any of those can result in data loss/unaccessability. It can also cause file corruption, RAID corruption and firmware corruption.
"any way to get it to power down / wake-on-LAN - ie get the heads away from the disc?"
Move the switch to 'auto'. This will make it so a network computer that has the NASNAVI will send keep alive packets to the unit. If the NASNAVI isn't running then the unit will go to sleep.
Not sure I can use the "auto" option - I need the NAS to respond to PS3 for media serving when PC switched off / NASNAVI not running.
I can't be sure I didn't check the "rebuild partition table" option as I spent a long time trying to get the firmware updated over WLAN - before I read somewhere in the forums that it's too slow, and I hooked up the NAS directly to the laptop. This time I'll assume I messed up and that explains the missing data. Thanks for answering the post
