unraid_1

That could be it, however the unRaid hangs happened after unRaid started loading. I noticed it would hang at various times and tried searching for solutions to them, here are some of them: "Attached SCSI removable disk" "configured for UDMA/133" "sata link down" One behavior that I thought was weird, is that half of the drives that were in the server 2008 software raid 5 work fine, while the other half give me the same error/hang. As I stated earlier, I won't be able to respond over the weekend, but plan on troubleshooting it some more around Tuesday or Wednesday.

That server is pretty much gone, I've used parts of it for my unRaid build, but I do have the OS disk still. As much trouble as it will be to put it back together, I'd rather RMA them first. Yeah, that was one of my first thoughts, I tried it all three ways. I'm getting ready to go away for the weekend, but I plan on trying to use the Samsung diagnostic tools on them, then calling their tech support up if that doesn't work. I'll post back once I do that. Problems like these make me glad that I switched to unRaid, lol. A bit off topic, but does anyone know of a script or program that will scan my folders and create a text file with all of the file names? I'll be honest, I have tried searching for it yet, but I figured if your reading this post anyways... In my own defense it is my own thread I'm hijacking, lol.

I went through all of the hard drives, and 3 out of 6 seem to be okay. I dunno what would cause a 50% failure rate of the drives. I'm guessing this must be something else. If nobody has any other ideas, I'm going to call Samsung tech support tomorrow. Before I do, I'm going to research the problem a bit more (I'm not looking forward to talking to tech support, lol). If they can't help me I'll probably just RMA as they're about a year old.

I'm going through all of the hard drives now, one by one. Some of them let me boot into Vista. I them go into Disk Management and convert them to Basic drives and format them. So far I've found 2 (of 4 tested so far) that won't let me do this. Regarding the drives that hang at "Verifying DMI pool", they hang boot in both Vista and unRaid. So, they are seen in BIOS, but hang the computer. Could this just be a case of a few hard drives going bad since I had my server 2008 array up?

Yes.

I want to put some 750 GB Samsung SATA hard drives I pulled from a Windows Server 2008 box that we're running software raid 5. They're not showing up... I disassembled the box to use parts of it for the unraid box but still have the hard drive with Server 2008 installed on it. I'm assuming the problem is with something done to the hard drives to make them part of the raid 5. I've plugged them into a Vista box and it hangs at "Verifying DMI Pool Data......." in the bios. Anybody know a solution to get these drives usable again?
