It was set-up as a Raid5.On the home page there is a message "Error has occurred in RAID Array1" - when I click on that it takes me to the Disk Management page, the message at the bottom of the page is:An error in a RAID Array has been detected.Select restructuring disk and click `Restructuring RAID Array`.All disks are checked, except Disk 2 (the one I replaced) - if I check that disk I can select the button "Restructure" - but then a message says I will lose all my data. How do I rebuild the system?Any help would be much appreciated.

Enter the number and then click the left-most of the 2 buttons at the bottom to continue. When you do so, the system thinks for a minute or so while the RAID array is altered to put the new disk into it. During that period the raid array is not accessible via the network. You will then be told (hopefully) that the restructur

Join Now i All, First let me say that I am a novice at working with the Buffalo Terastation storage devices, so I really need assistance from someone who is experienced with the product listed below. I have a Buffalo Terastation -HD-H1-OTGL/R5 with four 245GB SATA Disk Drives (WDC WD2500BB-22RDA) in a RAID 5. Yesterday, I encountered an error when I looked in my web console, the exact error message was " An error was detected in the RAID Array." I have never seen this before, but I would assume that since the four drives are in a RAID 5 that my data would still be accessible and it's NOT. I have tried power cycling the storage server but now when http://forum.buffalo.nas-central.org/viewtopic.php?t=21443 it boots up the web console says that Disk 1 and 2 are disconnected but not 3 and 4. On the actual server I can see 4 blinking red lights. How should I proceed with troubleshooting this problem? Please bear in mind that I have critical data that I cannot back up at this point and I would like to avoid losing it if at all possible. Thank you in advance!!

By the sounds of it you have 2 bad disks, but I will leave that up to the ones that are experts with your product. Good luck! 0 Mace OP Craig M Jul 14, 2010 at 3:54 UTC IT Journey, LLC is an IT service provider. There is a possiblity that 2 drives failed. RAID 5 can only handle a single disk failure.

I'm looking into it now. The server is out of warranty...so if its not a fan issue. Im pretty much screwed. I would find it hard to believe that 2 disks would fail at the same time though. 0 Mace OP Craig M Jul 14, 2010 at 4:06 UTC IT Journey, LLC is an IT service provider. Will they still talk to you on the phone? Sometimes its just your hardware that is no longer covered under the warranty. 0 Pimiento OP Tom5776 Jul 14, 2010 at 4:07 UTC 1st Post Just try the typical, unplug and reseat on the drives said to be disconn
Storage). Basically its a backup device - a mini-computer box with 4 harddrives, each 250GB, or 1TB total. Last week one of the drives died after a power outage (we get a lot of outages on san jose ave), and today i fixed http://chadnorwood.com/2008/02/26/terastation-drive-replacement/ it. However, it wasn't that easy - I spent over 3 hours on it - when it should have taken less than one. So i'm just gonna note a few things so the next guy might have it easier. Now http://murobbs.muropaketti.com/threads/an-error-in-a-raid-array-has-been-detected-buffalo-ls-wtgl-r1-v3-f-w-3-09.834263/ here's where i'm gonna geek out, so all non-geeks .. move along. When i first setup the terastion, i did a RAID5 + RAID1 - that means i got a 750GB partition out of my 4 250GB drives. So if an error any one of the four drives dies, i don't lose my data. I just pop in a new drive and rebuild. Easy. This worked great for 3 years, never had to replace a drive. Every now and then we'd lose power and when i powered on my terastation, it would take 1-2 days to check the disks before we were good to go. Last week Terastation would not recover - it would boot up for a minute, do disk check, an error in then turn off (power light was off). However, each of the four drive status lights would stay red, with disk 3 blinking red. After reading the manual, I decided to replace disk 3. I also read the wiki FAQ, so i knew i could replace with any same-size or bigger drive. I did this, spending almost 45 mins opening the terstation up, switching the drive, and putting it back together. Turned it on, and it stayed on. Yay! So now all i had to do is connect to the web manager interface and "rebuild the raid array". Once i logged in, it said Raid array 1 error - i clicked it, and I'd get to array 1, and it listed disk 1, 2, 3, 4 .. but the checkbox to disk 3 was greyed out. I spent a while looking through the web pages and decided something might be wrong with my new disk. I turned it off, took the thing apart (only took 15mins this time), pulled out my new disk, and basically connected it to my PC in a external USB drive box. It worked fine. Ugh. Was terastation broken? I tried the old drive, that terastation thought was dead. It also seemed OK by PC standards. Ugh. After going back in forth and trying different things, it turned out that the new drive had to have the jumper in Cable Select to work. The older

Buffalon link station oli alkanut vikavaloa polttamaan ja kun kävin web hallinnalla kurkkaamassa niin ilmoitti Error has occurred in RAID Array1. tarkoittaako tämä nyt sitä että toinen kiintolevy on vikaantunut, Hallinta ilmoitti vain "An error in a RAID Array has been detected. Select restructuring disk and click `Restructuring RAID Array`" Pitikin juuri nyt mennä hajoamaan kun kiintolevyjen hinnat korkealla. no, onhan tou jo raksutellut 3 vuotta 24/7. Onkohan nuo Buffalon nassit kuinka ranttuja levyjen suhteen? jos molemmat vaihtaisi suurinpiirtein alkuperäisen kokoisiin kun tuskin löytyy juuri tuota samaa mallia mitä tuossa on sisällä.

RAIDin rebuildi voi kuitenkin lähteä käyntiin jonkun timeoutin tai muun vähäisemmän virheen takia, joten levyt ei välttämättä ole yhtään rikki. Kait edes SMART-tiedot näkee? Jos levyjä haluaa vaihtaa, niin uusi ei saa olla sektoriakaan pienempi kuin vanha (olettaen, että vanha levy on otettu kokonaan käyttöön). Suurempi saa olla ja mallilla ei ole väliä.
