They are back up on ebay but the price is up to $300 + $24 shipping to my location. http://cgi.ebay.com/SuperMicro-SC933T-R760-CSE-933T-R760B-3U-15-Bay-Chassis-/360318031906?pt=LH_DefaultDomain_0&hash=item53e4a0d822 Now I am thinking again.

Well, after thinking about it I finally decide to jump in and go for the buy but too late. The listing has ended. With a little luck maybe a new listing will popup. Gues it doesn't alwasy pay to think.

Anyone know if the trays in this chassi are interchangeable with the SuperMicro 5 in 3 bays?

Check out the combo with the Corsair 750HX. If you use both discount codes BFCORPSU, 10% of corsair psu and EMCZZYR25, 10% off hard drives. Pretty sure they will both work because they are for different producs but not 100% certain. You are essentially getting the PSU for $64 after a $20 rebate. Not bad if you need one. Good today Nov 4 only.

There is a used drive bay up on ebay with a starting bid of $14 + $7.50 for shipping (to my place in Ohio). It is a relisted item. No one bid on it the first time arround. No, it is not my listing. Just noticed it while look for a deal on a full 590 case.

Trying to order one but the checkout is going so sloooooowwwwww...

Anyone know for sure that Tom is well and continuing to develop and support unRAID? Have not seen a forum message from him in over two months.

That is what I would have tried, without the jumper installed. Then installed the jumper and precleard or formatted it. Sorry, I didn't read where you had already tried that. I would use the CD ISO version not the windows version. No real reason other than trying to to take out as many variables as possible. If that doesn't work there may be more going on internally in the drive than what on the surface seems like a simple sector remap. There is a lot about the WD advanced format drives in this thread. http://lime-technology.com/forum/index.php?topic=5384.0

Have you thought about how you would add SATA ports? Looks like this board will take one MV8 and one PCIe two port card. Giving you a total of 16 ports. Where do you go from there? PCI slots? Port expanders? Might be worth giving consideration to a mobo that can take two MV8s if you think you will be adding a lot of drives down the road.

My understanding from what I have read is that installing the jumper remaps ALL sectors (granted they are simulated 512 byte logical sectors) to Logical Block Address x - 1. So real sector 0 becomes -1 (can't be addressed), 1 becomes 0, 64 becomes 63 (convienent). This makes LBAs (after translation) 7, 15, ... 63 line up to the physical 4k sector boundries which results in the best performance for partitons that start on one of those boundries. If a drive is formatted in any system without the jumper and then the jumper is installed everything is off by one 512 byte sector. Drive signatures, partition table, partitions, partition boot sectors, EVERYTHIN. This seems to cause some systems to see that something is on the drive but can't resolve the structure, thus resulting in many errors. On the other had if the drive is completely empty (with or without the jumper installed) systems don't get confused because they see an empty drive. I have read that people have been able to add the jumper to a prevously formatted drive by using any utiltiy that will completely earase the drive to zeros (preclear does not exactly do this) without the jumper installed and then install the jumper and format or preclear it. Maybe all the problems caused by the jumper including RMAs is why Samsung F4 drives don't have one. In you case the partition might start on LBA 63 after installing jumber but the rest of the drive structure is still hosed.

Firmware 3.1.0.21 is now available here. ftp://ftp.supermicro.com/driver/SAS/Marvell/MV8/Firmware/3.1.0.21/ Both my cards came with 3.1.0.15N. I have no idea what the difference is. As usual, flashing firmware is a bad idea unles you have a really good reason to do it. In this case I certainly don't know what that reason would be. I did some searching but could not find an explanation of the new firmware anywhere.

Thanks!!! Just yesterday I added drives 19 and 20 to my server and wouldn't you know, I started geting the boot failed message. Disabling INT 13 on the MV8 cards did the trick. Back up and running with all 20 drives (27TB total) connected. Do you have some magic that will make the preclears run faster?

Been there. I did almost exactly the same thing. 1. Put some files on a drive for whch I had calculated CRC codes. 2. Shutdown unRAID 3. Pulled the drive (1TB) 4. Inserted new drive (2TB) in exactly the same place the 1tb drive was connected. 5. Started unRAID 6. Probably had to manually start the array, don't remember for sure. 7. unRAID rebuilt the 1TB partition from all other dirves in the array and then expanded the file system to the full capacity of the 2TB drive. 8. Checked the files against the CRC codes. All were good. I did nothing to change the drive configuration. unRAID detected the new drive and did the recovery without my having to do a thing. It automatically updated the disk slot to reflect the new drive. In my case the new drive had been erased to all zeros using a disk wipe utiltiy in another computer to break it in, so to speak. I don't know if unRAID would have done anything differently if the 2tb drive I put in to replace the 1tb actually had data on it. Maybe someone with more experience knows the answer to that.

Might not be too late. Looks like eWiz has them for $95 with free shipping using the latest coupon code. Unfortunatly, you can only use the coupon one time. Thinking about getting one and then giving some relatives a call.

I have: ASRock M3A785GXH/128M BIOS 1.70 AMD Athlon II X2 245 Regor 2.9GHz G.SKILL Ripjaws 4G F3-12800CL9D-4GBRL two Supermicro AOC-SASLP-MV8 I currently have 18 drives in the array totaling 23TB and two more that are ready to go in. I built it about 6 months ago and it is running nearly all the time. Been about two months since the last reboot. Once I figured out what worked and what didn't it has been rock solid. There has never been an unplanned shutdown. No lockup, no failures what so ever. It just keeps running. If I could install new drives on the fly I would probably never shut it down. Anyway as you probable know it has 3 PCIe slots that can take a 4x card. I only have two MV8s but suspect I could install a third if I wanted to. If you lookup my original post on the mobo you will see I had trouble mixing MV8s with a Monoprice SATA controller. Could never get it to boot with both installed. I suspect card BIOS conflicts. Never tested with the base bios on SATA card only the RAID bios.

eWiz / SuperBiiz has a $15 coupon (class15) good through 8/22 or "first 2,000 uses" on an order over $100. After coupon that makes a 2TB sammy $99.99 or AOC-SAT2-MV8 $89.00. I don't see the AOC-SASLP-MV8 list, they must be out of it.

Looks like SuperBiiz has them too. $112 - $15 for discount code SUNSHINE15 = $97. Free shipping. But you can only get one at that price, if the coupon code even works. http://www.ewiz.com/query.php?categry=0&s=saslp-mv8

Is anyone using two of these in on system AND also using the magic packet to do WOL successfully? When I have just one card installed WOL works as expect however when I install a second SASLP-MV8 card the sytem does not shut down properly. The power goes off but then a couple seconds later it starts back up, just like it received the magic packet. In order to get the system to shutdown and stay shutdown, I have to disable WOL in the BIOS. Of course that means I can't start it up remotely. Kind of a catch 22. Anyway not sure if I should contact the mobo support or Supermicro support. So I was wondering if anyone has this working and if so what mobo you are using?

These drives ship with SMART reporting disabled. Seems kind of dumb to me but it is a fact. I have used 5 of them so far and had to manually enable SMART on all 5. unMenu or preclear scripts can create some pretty ugly log messages in certain conditions until SMART is manually enabled. Check this topic. http://lime-technology.com/forum/index.php?topic=6419.0

Here are the temps as reported by unRAID about 1/2 way through a parity verify. Looks like the Samsung 1TB and 1.5TB temps are low. The Samsung 2TB temps are about the same as the 1TB WD temps.

I did in fact breake the script. Wordpad did something bad to it. Downloaded and istalled Notepad2. Made the edit using a clean copy of the script and it is working now. Started 6 more preclears, four of them are in their 2nd or 3rd pass, the preread is being skipped after pass 1. Joe: Thanks again for the update and link.

+1 for Acronis True-Image. I have need using it for a couple of years to do partition imaging and partitioning imaging is the only thing I do with it. Have never tried any of the other features and have never tried to do an image of a running system. I just don't trust anything that claims to be able to image a running system. I just isn't natural. I have sucessfully restored partitions to new drives multiple times and often resized the partition in the process. Nearly all my systems have multiple bootable partitions and a boot menu. Sometimes Windows gets anoyed when partitions are moved arround or drive signatures change so sometimes you have to fix the boot process. Anyway, with the current TI 2010 I used something called Mustang PE to create a Win 7 pre installation environment ISO image with TI installed on it. I then put the ISO on a USB stick with other ISOs and use MultiBootISO so that when I boot from the USB stick I get a menu to select the specific ISO I want to load and run. I have things like Memtest, vendor drive testing utilities, disk wipe tools, etc all on one handy USB stick. One nice benefit running TI in Win PE is the hardware support. Also by mapping a network share to a drive letter the images can be saved to or read from a network drive.

Made the change using wordpad from Windows 7. Suspect I might have broken the script by adding CRs, will find out when I try to run it. One way or another I will get it working even if I have figure out how to edit the script using a UNIX editor. My two new 2TB drives arrived in the mail today so this will save quite a bit of time preclearing them. Thanks! Jerry

When doing a multi pass preclear I am wondering if there is any benifit to doing a preread for passes 2-n? Considering that a post read/verify just finished does doing another read pass before the write pass contribute to the processes? Running multi pass preclears on 2TB drives takes a long time. Regardless, thanks Joe for a great utility. I added six precleared drives (2x1.5TB & 4x1TB) to my array with only a few minutes of down time. I also ran all six preclears at the same time. Worked perfectly.
