abernardi Posted June 3, 2010 Share Posted June 3, 2010 If you've been following my unRAID build, I had a bad Samsung 1.5TB which was a pull from an external "Story" drive, Model HX-DU015EB practically brand new. So I swapped it out with another, exactly the same drive, and I'm having troubles with this one. I ran a preclear on it and it came up with a few problems that Joe L. pointed out in my previous thread: http://lime-technology.com/forum/index.php?topic=6601.0 I finally installed a 2TB parity drive and let it build overnight, SUCCESS! However, it's reporting 101 errors all from this new Samsung drive. I'm attaching the syslog and a smart report I ran this morning on the drive in question. I'm also attaching the smart report for the previous Samsung drive. The previous Samsung drive had a number of problems including: 197 Current_Pending_Sector 0x0012 035 035 000 Old_age Always - 2718 but there only seems to be 1 on the current drive. Anyway, I could use some advice. Are there any similarities between the reports on these drives? Could there be a problem with Samsung drives and unRAID?

rsd Posted June 3, 2010 Share Posted June 3, 2010 I have 2 of the Samsung EcoGreen 1.5tb's in my unraid for a while (and same for a friend) and no issues. Maybe bad luck? Link to comment
Chris Pollard Posted June 4, 2010 Share Posted June 4, 2010 Same as above. I have 7 Samsung drives in my system and haven't had any problems. Link to comment
Rajahal Posted June 4, 2010 Share Posted June 4, 2010 Likely bad luck or a bad batch of drives. I also have several Samsung drives that work well in unRAID. However, I did discover early on that many Samsung drives require a jumper to work properly (I had one that showed up as 32 mb until I installed a jumper, when it finally showed it's true size of 1 TB). If you have some jumpers laying around, you could try installing one (pins 1-2, I think) to see if it helps. If not, then just RMA the drives I suppose. Link to comment
abernardi Posted June 4, 2010 Author Share Posted June 4, 2010 Looks like I'll need to RMA these things. The problem is, I put one back in it's external case and I'm having trouble finding a program that does a SMART report on USB drives in Windows. I did find one that checks for errors and indeed some sectors are coming up bad, so I guess it was just wishful thinking that unRAID and Samsung might not get along. I might be screwed with the RMA though, because I broke a seal on the external case that nullifies the warranty. Maybe I can return them as bare drives? Anyone with any experience in this?

Rajahal Posted June 4, 2010 Share Posted June 4, 2010 Usually the manufacturer will release a program that is able to run SMART tests on USB drives. SeaTools for Seagate drives, for example. I believe Samsung's version is called ESTools or something like that. You can find through Samsung's support website. I think it is doubtful that Samsung will accept an RMA on an external drive with a broken seal, but you could always call and ask them. Link to comment
aiden Posted June 5, 2010 Share Posted June 5, 2010 I have 2 1TB Samsung 7200 rpm drives that I just put into a Synology disk station. I ran preclear on them for 3 cycles each. One of them completely aborted preclear after 3 hours, no matter what I tried, so I rma'd it. The replacement passed with flying colors. My point is that lemons happen, but I don't think there are any systemic issues with Samsung drives in particular. Certainly nothing like the Deathstars of 2000. Link to comment
