A disappointing purchse at this stage! I have a N2050 and have installed 2 x Seagate ST3500641NS 500GB drives and the unit is failing to build RAID 0 or 1. Has anyone found a 500GB drive that works? So far Thecus support has not responded to my support request.
I have a pair of brand new WD5000K's (Western Digital Caviar® SE16 WD5000KS 500 GB SATA II) and they do not work in the N2050.
Thecus has sent me a replacement (actually an N2050GX, which is the green color rather than the light blue N2050UD), and the same thing happens in both:
The blue lights never blink, indicating that no raid array of any type is being built.
When you bring up the winXP adminTools->compMgmt->storage interface, it shows two drives attached. One is "dynamic" and the other is "unreadable". Of course, if the raid part were working then only one drive would be showing up.
They have suggested to me that these drives will work in the N2100 (not sure why they think that), but since the N2100 only has gigabit, not eSata, the access read/write speeds will nowhere near as good, and I'll have to be fiddling with the static IP's all the time to get it to work both with my laptop directly (cross-over cable) and on my office LAN.
I can confirm that the Maxtor 500GB drives (L01F500) listed in the new compatibility doc do work in the n2050.
I also discovered that one of my WD5000KS's was having problems and I've RMA'd it. However, that was only a problem writing to a particular spot, there was no trouble mounting and even formatting, so it still doesn't explain why the n2050 raid controller wouldn't recognize them at all.
Separately, I've now drilled holes in the front of the plastic chassis to add circulation. Two rows about 5 holes, each about 3mm diameter. I took off the top plate that says thecus (I'm not one for aesthetics) to make room for the top row of holes. The bottom row is in the white lower section (which is nice and thick and still strong).
The fan now seems to be putting out noticeable flow, whereas before it didn't. We'll see whether it seems to help with heat much or not.
Be aware that the 500 GB SATA 3 GB/s drives in the Seagate/Maxtor L01F500 retail product are actually Seagate model STM3500630AS drives, now part of the Seagate Barracuda 7200.10 product line. The N2050 HDD Compatibility Report shows the Maxtor L01F500 drives as having been tested OK.
These drives are recognized fine by the N2050 and the initial RAID1 operation is fine; if one drive fails, the remaining working drive is still accessible. However my tests at replacing a (simulated) failed drive with an identical STM3500630AS (no partitions, identical drive firmware) show that the N2050 refuses to rebuild the RAID1 array. Thecus tech support is still investigating this for me.
So for now if one of the RAID1 drives in the N2050 fails, I'll copy off the data from the remaining hard drive to another large external drive. Then I'll replace the failed hard drive and re-initialize the pair of drives for RAID1. Finally, I'll copy back the saved data. Clumsy and time consuming, but it should work.
I will do a not so simulated test tonight. I have the N2050 attached to a DirecTV DVR. This week the blue light on drive one started flashing So I ordered a new Seagate 7200.10 750GB SATA drive and I will install it tonight. Since the drive is connected to a DirectTV receiver I do not have the luxury of backing up my shows before trying to rebuild the array. I will just cross my fingers!
Well I replaced drive one and booted up the Thecus drive and my DirecTV receiver and im not sure if it worked or not The blue light on drive one is still flashing, but now the green activity lights on drive one AND TWO are not flashing like they were before, so im hoping the array is building. I am still able to view all of my shows, FF, RW, pause, record, etc. so im just going to wait it out and hope that the drive is building. I will call Thecus tomorrow and see if they have any suggestions if it doesnt work. I dont want to start switching the drives from bay to bay in case I lose all of my recorded programs. I will post my results.

I woke up this morning and the array rebuilt fine. I now have two solid blue lights! This drive is AWESOME!
For anyone who is interested I threw the 2 Seagate drives in the enclosure and connected it to a DirecTV HD DVR using SATA II. Thats it, you boot up the DVR and I now have MUCH more capacity to record. I have disconnected and connected the Thecus drive almost a dozen times now. Everytime I boot the DVR back up I cross my fingers and hope this wont be the time I lose my shows. I havent been dissapointed yet, and after this little saga I am more impressed then ever!
