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 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!!

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 http://chadnorwood.com/2008/02/26/terastation-drive-replacement/ on san jose ave), and today i fixed 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 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 an error - that means i got a 750GB partition out of my 4 250GB drives. So if 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 an error in before we were good to go. Last week Terastation would not recover - it would boot up for a minute, do disk check, 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 broke
