HDD's Failing, RAID Damaged...I Just Bought This Yesterday:(
#1
Okay...I havent setup a NAS in a while. I did enough research based on my budget to see that this was the best solution I had. So my N4100PRO arrived yesterday along with (4) Seagate 2TB SATA Drives. Here is my network configuration and equipment:

- Cisco Valet M20 Wireless-N Router (192.168.1.1).
- iMac (Late 2009, 10.6.7).
- N4100PRO NAS
- (4) Seagate Barracuda 2TB HDD's (only 2TB Seagate HDD on Thecus Compatibility List)

I finally got the NAS connected and started the browser. All HDD's were tested upon opening them to ensure each was in working condition before I installed them into the cages and NAS. This was done with power and network unplugged prior to initial boot up. In the browser, the NAS showed 2 of the 4 drives with warnings. Knowing the drives were tested and working, shutdown the NAS and removed the HDD's and swapped the two bad ones where the good ones were in the NAS and booted again. This time, only one drive showed failed, but in the same slot (top slot in NAS). I ran the bad sector check all night, checked this morning and all lights were green and no warnings.

Started RAID5 creation choosing all 4 drives as used...started building NAS. Within 45 minutes, the alarm sounded, two drives had red lights again (same ports as before) and the RAID showed as damaged. Now I am stuck and have no clue how to continue. The manual online and on the included disc is uselessSad It doesnt give me any additional information and now I fear either the NAS is bad or some of the drives are bad.

Can some explain what I can do to clear these drives, reformat and rebuild the RAID? Or perhaps some instructions on recommended steps to take with bare drives from installing them in the NAS to building the RAID? did I miss something or did I just get ALL BAD PARTS????

Please advise...thanks!

Sounds like you got some bad drives, one of the four WD hard drives I bought works as a normal hard drive, but shows the same signs yours did. I am currently sending it back to get another.

How did you test the drives? Did you use Seatools to check them? Long test? short test?

Last thursday one of my drives also failed after more then 2 years of hard work. I took it out and tested it with Seatools (I have 1.5TB seagate drives) and the short test and smart was okay but the drive failed on the long test.

Check it with Seatools to make sure your drives are indeed in good condition.

I don't think I should run seatools on a WD drive. But I tryed to connect it again to the PC and every Partitioning program I have shows it as bad disc.

If that is the case you should return it, to make sure you can always use the diagnostic program of Western Digital.

I am facing the exact same problem.

My 4x Seagate Green 2TB HDDs are new and they have all passed the long tests of SeaTools.

The problem is random and the latest "RAID damaged" was after 14 days of the NAS up and running, 2 HDDS will show I/O error in the NAS and my RAID will be damaged/gone causing me to lose my data. Sometimes it's Disk 1 and 3 and other times could be 2 and 4 though I never change the position of the disks.I am considered lucky because there are times when the problem will come after 2-3 days of uptime.

Support has asked me to RMA the box and I did but the problem is still occurring. I am thinking it's not the box but rather the firmware. Anybody has similar problems?

I had this problem too, but with me it started recently after I had the box for more then 2 years.

I send it in to RMA and they've changed the power supply of the N4100Pro. After this I haven't gotten the problem again, I also bought a small UPS for it because in my neighbourhood the power goes out sometimes and I think that was the cause of it all.
