  1. I ran some additional tests, and have produced some interesting results. I hooked up four drives to my windows system inside one of the supermicro backplanes. I set up a striped disk across three of the drives, and leave the fourth as a normal simple partition. Test 1 - I run a speed test on the fourth drive, with no activity to the other drives. I get the expected R/W speeds. Test 2 - I run a speed test on the fourth drive, while copying a large file to the other drives. The drive performance drops significantly. I remove the drives from the backplane, and hook them directly up to the system. Test 3 - I run a speed test on the fourth drive, with no activity to the other drives. I get the expected R/W speeds. Test 4 - I run a speed test on the fourth drive, while copying a large file to the other drives. I get the expected R/W speeds. Here are the actual test results.

Anyone have any insight on the CSE-M35T-1? Maybe they aren't all they were cracked up to be? Maybe I got a bad batch? Thanks in advance.
  2. Hi, I had disk3 rebuilding and disk1 had failed writes either during or shortly after the rebuild. disk1 showed red ball and disk3 showed orange ball. I saw that orange usually means pending cache writes, so I went ahead and proceeded with starting to deal with disk1. I disconnected and reconnected disk1, and it showed a blue ball and asked if I wanted to rebuild the disk. I stated that I did, and then it presented me with this, which now says both my disk1 and disk3 are orange and unformatted. Is there any way to restore the array in the current state? I am thinking I will have to recover the data and rebuild the array a disk at a time. Thank you, syslog-2012-12-09.zip
  3. Ok, still not sure what was going on, but I fully shut down and left it for about 10 minutes, and ran through a cold boot cycle. When it came up, it looked exactly the same, but no disk was assigned to disk1. I assigned it, and all of a sudden it is found and ready to come online and start the rebuild. When in doubt, reboot (again and again) Thanks for all the help guys, seriously. I really appreciate it!
  4. Got into unMenu and I can see the drive, and it shows the right size. :-| Notice though, the name is missing the P in the image. That is strange... WDC_WD20EARX-00P_WD-WCAZA8408153
  5. IC, Adding a drive to a second install like that doesn't change the drive data as long as I don't spin it up, right?
  6. That would be to get the actual drive size to compare against the previous and confirm that is the problem, correct?
  7. A soft reboot was performed after the other steps (unassign, assign, reseat hard drive, reseat sata connections, switch sata port). The system shows the same status after each action.
  8. Are you sure 4.7 supports hot swap? Somewhere in the back of my head I'm remembering hot swap after stopping the array (warm swap?) being added as a feature in the 5.x series somewhere? I am not sure, but I have done it multiple times in the past and the hot swapped drive seems to be working fine. It is the other one that is giving me fits. I can shut down from now on.
  9. Thank you for the reply. It does allow the drive to be assigned. I did not assign it to a different slot. How can I verify what unraid is expecting for the size vs. the current size?
  10. Hi, Unraid 4.7. Disk 3 showed redball, so I stopped the array and hot swapped for another identical drive. I updated in Devices and when I went back to Main, Disk 1 shows that it is missing. I double checked the configuration, unassigned it, reassigned it, reseated it, rebooted the server, swapped the sata port, and still it shows that disk 1 is missing. Syslog attached, screenshots below. Please help! syslog-2012-11-28.zip
  11. My unraid version is 4.7. All drives are connected to the motherboard, not the RC-218. The drive that was in the second bay was connected to the RC-218, but the bay/PSU causes the problem even without a drive in it, and disconnected from everything except the power.
  12. It has to be a faulty PSU or a faulty bay. Any idea how to figure out which one? I don't know how to test the power pulled by an individual molex or sata power port. I have a spare Rosewill RV2-700. The problem is that it is 700W and can probably supply the second bay with what it wants, even if it is faulty.
  13. It had 1 green drive in it. The drive would have connected to my controller card. I tried to "recreate" the rebuild by initiating a parity check and plugging in / unplugging the power to the bay. Without the second bay plugged in I run about 95 MB/sec. When I plug in the power to the bay containing the single green drive it drops to around 58 MB/sec. When I plug in the power to the bay containing NO drives it drops to about 40 MB/sec. When I plug in the power to the bay with NO connectivity to it whatsoever except for the power it drops to about 40 MB/sec. Any thoughts?
  14. Hi all, I had a drive redball on me. During the rebuild process I hooked up my second 5-in-3 Supermicro bay in order to expand the array when the rebuild completed. When I plug in the power to that 5-in-3 bay it drops my rebuild speed from about 47 MB/sec to 2 MB/sec. If I unlug the power, it goes right back. Any thoughts? I am using a 1 x SATA to 3 X molex power converter to hook up the bay. I have 5 drives in the system currently (in the first bay), 4 of them green. The second bay I was trying to hook up contains 1 green drive. My system build is: Motherboard: ECS A885GM-A2 (V1.1) AM3 CPU: AMD Sempron 145 Sargas 2.8GHz Socket AM3 45W Single-Core Desktop Processor SDX145HBGMBOX PSU: CORSAIR Builder Series CX430 V2 430W RAM: Patriot 4GB (2 x 2GB) 240-Pin DDR3 1333 (PC3 10666) Controller Card: Rosewill RC-218 Hard Drive Array: 2 X Supermicro CSE-M35T-1B 5x3 Case: AZZA Helios 910 Thanks!!
