Set up RAID on Buffalo Two-Drive LinkStation or TeraStation NAS

Great walk-through. I have Linkstations dual LS-WVL and quad LS-WVL. Both working great from day one for the last 4 - 5 years and never switched them off. Both using WD green HDs everyone is recommending not to use them for NAS. Both running in RAID1 and both acheiving a very simmilar transfer speeds 60-80 MB/s. Both used as DLNA without a drop of frame even in K4 speeds.
Only recently my quad NAS dropped the transfer rate to 10MB/s and sometimes even slower. I had a problem just before that when one of the HDs dropped out (red light) bit after rebuilding the array it came back and I didnt thinkk too much of it. After being annoyed with this slow speed from both arrays I decided to physically remove all HDs and check them for a surface test and surely enough one had a few bad sectors. Interestingly Buffalo slows down the speed of all drives to the slowest in the system (even in different array) and this is why I didnt suspect a HD failure. Got a new replacement HD (they are all 3 TB) done the firmware update and started from scratch on this Quad NAS. Tested the share folder and speed is back to up to 80MB/s.
The only thing I was concern was its orange light and checking array status. I new it is a slow process and it can take hours (on 3 TB) but since I have done this years ago last time, I forgot how to check the progress. I knew I was doing it last time but this time I could not find it anywhere until I saw this video. Simple horizontal slide bar! Didnt see it!
And for those who can not set up Buffalo properly or have problems and throwing mud on this NAS just try to play with D-Link NAS drives and thheir settings. You will be back running to Buffalo! Friend of mine got the dual LS-WVL for her home network and she has got a few home PCs (all the kids and her work laptop) sharing data and one of the daughters has a Mac (Hackintosh) with Snow Leopard 10.6 sharing files and using attached printer to USB port to the same NAS without any problems. Great little box: sharing files, printer server and DLNA feature and all with RAID1 safe file storage for the 3/4 price of "known" brands.

I don't know if I'm being an idiot but after it's don through the setting up of raid 1, it's asking me to insert a username and password.
I've tried my PC login, the Buffalo admin and (altered) password and it doesn't let me in, it comes up with: Login failure: User name or bad password.
what is going on?

Thanks for walkthrough!

Extremely helpful video. Makes a confusing/non-existent description on the manual very easy - Thanks !

Can users in an office access this like a shared folder on the network or do they all need to use the software, etc? I'm just a little confused, but need a solution asap. Thanks!

Great video- I followed steps exactly and it made a difficultl process easy.

dmcs2003, Thanks for the feedback. The advertised capacity is assumed in RAW capacity or RAID-0, yet RAID-1 is the more popular setting. We apologize for the confusion, and we will report this feedback to the default configuration team. We're sorry for the confusion, but as you stated, it does ship in RAID-0, and as you noted, switching to RAID-1 involves data loss. As stated, we'll report this to our team for feedback. Thanks for your comment, Brian

Strange, the video says the default mode is RAID 0, however, the narrator continues on to say most people change it to RAID 1 for the redundancy. Why not just ship the damn thing in raid 1?! I spend an entire day copying data to the raid thinking it should be in raid 1, however, I found out that it was not. Now I will need to backup (another day lost), then change the raid array to 1, then waste an complete day putting the data back on. :( This is very poor planning on Buffalo's part!

I have two buffalo link station products and they both failed me in the first month. What a POS!

Excellent. So simple. Was scared before strating.

What are the steps to install a 2nd drive (Keeping default RAID 0)?

Excellent - converted a new configuration to a dual disk RAID 1 device. Just as the video says. Much better than a PDF manual.

I have the latest firmware for my LS-WXL and I still get this problem when trying to change from Raid 0 to 1. Buffalo has made an absolute dog's dinner of the firmware. Utterly flawed NAS drive. Avoid people Avoid!

Would be nice if this actually works. What the user in this video doesn't get is a barrage of "Failed to operate disk. Please resubmit after restart" , "Failed to operate RAID array. Please submit after restart"error messages, followed by a dead NAS. No amount of forcing different firmware updates, reloads, TFTP updates, etc can seem to get this thing into RAID1. Looking at the forums it seems I'm not the only unlucky one...

Good Vid. It should be mentioned in the Linkstation documentation. I spent all afternoon figuring this out... after much googling to get the browser interface to display in English instead of Japanese! How long should it take to build the array? The browser settings now say that the status is normal but I still have the orange LED on the unit flashing 1-6 over 14 hours later...
