I try to answer the most import information
If it's a technical question of any kind, please remember to include:
Your Operating System you are using to access your NAS.
Windows 7
NAS model
TS-412
Firmware revision
not the latest version but nearly, sry don't know exactly.
I can search via ssh if neccessary
Network Setup (ie Single Port or Port Trunking)
No, I have two used ports but each one has his own IP
If Disk related please also specify:
Drive Configuration: (ie SingleDrive, RAID0, JBOD, RAID1, RAID5, RAID6, RAID10)
Raid 5 on Bay 1+2+3
No Raid on Bay 4
Number of drives
For each drive please provide:
Drive Manufacturer (ie Seagate, WD, Hitachi, etc)
Drive Model
3x SEAGATE Barracuda 7200 3000GB 7200 U/min with 64MB
1x ?? but this HDD is still working as it should
So now exactly a description what has happened.
Had a power breakdown on 2014/05/10.
On 2014/05/11 I have moved some private Pics to the raid successfully.
On 2014/05/12 My shares were not accessible. I have seen, that Bay one was blinking red
I have restarted the Raid. No rebuild or something else. I have bought a new hdd (same model)
and inserted it to rebuild. Status LED is blinking green, HDD is green. It seems that when starting qnap.
the qnap is trying to rebuild. but after 3h the system is doing nothing any more. Only ssh is possible.
Web server seems to be down so the webadmin is not accessible
I have got a little help from a guy who has linux know how, here is what I've got from the ssh.
It seems to be a strange config. IMPORTANT these are the results with the new disk on BAY ONE!

I have no backups, because why do i have to with raid5? Now I know why
It would be very kind of you if you could help me. It seems that my partition is corrput and I have a bad superblock.
What else can I do?
Please be patient with answers, because tomorrow we are going on our honeymoon and I am back on 2014/06/10, but I am depressed right now.
I've paid much, just to know now, that my data is lost, maybe forever. And I know my misstake is that I've not done a double backup.
Best Regards
