For 40 HDs at the lowest cost:
New MB with two PCIe x16 (can be x8), integrated video and 6 SATA ports
======================================================
Controllers:
2 x M1015 flashed in IT mode - $100 each or less if you can wait for a deal
one Intel 24 ports SAS expander - $250 or less...
You probably should try
sasflash -o -testlsall
This should provide you the status on all 8 ports. If not devices recognized it will display Link Down - so the possible reason is wrong cable (but the one you bough appears to be the "right" cable)
Why you do not flash in DOS mode. Make bootable flash drive (unetbootin) and go from there.
And disable any hardware feature in the BIOS (including the onboard SATA controllers and LANs) before trying the flash procedure
I always had impression that the LSI1068e (and 1064e) based controllers (such as your 3442E-R) do not support 2TB+ hard drives and thought this was a nice way for LSI to make sure you will buy newer ones bases on SAS2008 or better.:mad:
Perhaps the fact that you use expander somehow masked this...
Do not forget about thst one - http://www.storagereview.com/seagate_wins_525_million_arbitration_award_western_digital
That for sure will facilitate the return to the normal....NOT for a lo...ng time
You know that for a home storage they are other solutions that allow you to mix any kind of drives (size, interface, speed, etc) while providing a single drive protection - FlexRAID, unRAID...
You can also get a low power ECC system if you select AMD - many of the Asus motherboards support ECC, most if not all of the recent AMD CPUs also provide the ECC functionality for "free".
On the Intel side - there will be Atom grade ECC capable CPUs to be released in the next few months, but...
Kids will be kids so why not try to remove the "power switch" for the time being.
1. All the recent hardware and PSUs can support a power up by the keyboard (you will need to read your motherboard manual to see how to set it up)
2. You have a home network and you have a router. This router may...
This card is a different animal provided that you use it in a motherboard with proper PCI-X slots (64 bits either 133MHZ or 100MHz)
The problem is that PCI-X has been kind of obsoleted - you still can find motherboards with 64 bit 133MHz or 100MHz slots but they will be very expensive if...
This thread is about Solaris and I am not using that so cannot comment.
But no problems with a single M1015 with IT firmware in Unraid - spin-down work fine for me (I have only 4 drives on the first SFF8087)
It is good that you have your signature - otherwise GA-MA790GP is not a valid MB number.
The one from you signature will take the CPU you want to use - but make sure to flash the BIOS in the existing system beforehand. How successful overclocking it is different question.
Now - the puzzling...

I really doubt that this is the case.
The lower warranty IMHO id due to the different distribution channel where these external HDs are mainly sold and where the "extended warranty" and other value added crap is the major money maker...
What is the firmware of your BR10i:
See the IBM change history here and especially the latest critical fixes:

The OP has to understand that any HD reliability data, even if exits will be very closely guarded secret.
Even the Google study did not provide much info.
However from time to time there is a little bit of useful info:
1. Relatively recent study by Russian date recovery lab published in THW -...
These are (from Intel's P965 specs) the invalid memory configurations:
The following configurations are not valid with the Intel 965 Express chipset family:
• 64-Mb, 128-Mb, 2-Gb, and 4-Gb Memory Technologies for DDR2
• x4, x32 DIMMs
• DDR2-533 with any Speed Bin Timing...
The PC won't boot as it supports 4GB max memory:

You can check out the Japan postal office - usually they will have handy what the custom regulations and exemptions are. You can ask your relatives or friends to mark this as a gift as in this way usually you can get a higher value customs exemption.
usps.com should provide you with the exact...
Or you can buy from EBay cheap LSI clones sold under the IBM moniker:
1. M1015 - if you want SATA3 and 3TB+ HD support;
2. BR10i - just regular SATA2 and I believe limited to 2.2 TB HD size.
Depending from what you are going to run you can buy just a single 8 drives card and use four of the...
What is you hardware configuration - especially is your system ECC capable or not as this may be the cause of your data corruption and not the URE - and I believe the URE on the consumer level HDs is nowadays down to 1 per 10^14 bits ( around 12 TBytes)
Going from your posts you recently went...

Did you attach any other drives to the same cable - sometimes these cables are bad or you could have gotten the wrong one (reverse instead of forward for Norco 4020)
Also have you checked the Supermicro firmware - is this 0.15 or 0.21.
You may have to update the controller firmware too if it is...
Forgot to mention about the Gigabyte "dual BIOS" - in many cases this is a marketing gimmick - they are NOT using two flash memories but instead using one of the system hard drives where they will create a host protected area (HPA) and copy the Bios image there.
There is no set guideline as to...
Your motherboard - Gigabyte GA-MA78GM-S2H probably will support the 3TB and higher HDs as a non-bootable device. However you did not mention the OS you use and this is important factor in the 3TB compatibility. You may have a problems under XP and XP-64bit.
Since you have Gigabyte I believe...
Many of the gadgets we use nowadays are designed to be charged, powered from 12V (the car battery).
An old power supply can be easily modified to provide such power.
However I will stress that if you do not know what are doing opening and messing around with one PSU can kill you.!
For...
1. Highly reliable system usually uses ECC memory and I believe that most of the Asus boards (at least in DDR2 time) supported both regular and unbuffered ECC. I believe that most of the Gigabyte (except perhaps the very high end) did not support that feature.
2. For low power AMD - that...
I am not so sure. The problem is at power up (you still will have to do it from time to time - upgrade and maintenance, power outages...)
Since these are 3.5" HDs they place a higher requirements on the 12V line. This start up current can be 2-3 Amps (for a few seconds)
Worst case - 20 HDs x 3...
