Re: HP MediaSmart EX485 - System Drive Failed - Questions Update:
Short story: Hard drive spun up, Nothing essential lost. New drive installed, server working as it should.
Longer story:
Recap: The WHS wouldn't boot up. Heath indicator light detected a problem, and the server was unresponsive. Reinstalling WHS failed. I was unwilling to try a destructive reinstallation.
What happened:
Removed all drives from the HP MediaSmart - I had 2. The 750GB system drive and a 1.5TB drive. Installed a new 1TB drive as the system drive, and put the 1.5TB data drive back in. Started a server recovery, and it worked.
Upon some investigation, it looks like I had data-duplication on for most of the data - I didn't lose any media (movies) or other files. I did lose some of the weekly workstation backups from the last 4 weeks, but that's not a problem as none of the workstation drives failed.
Backups resumed, and everything seems to be working properly. I hooked the 750GB drive up locally to a desktop PC, and it spun up and I was able to see the contents. It appears it's working fine, so I don't quite understand why it didn't work in the MediaSmart unit---I guess something got corrupted where WHS could not reinstall itself onto the drive.
So, everything is back working, and nothing lost. BBU is charged, properly hooked up back to the server and shutdown will occur when it's on battery for longer than 2 minutes, so power issues shouldn't be a problem again. Not sure what I'll do what this 750GB just yet. Probably discard it.

If you want me to take a look at the health of the 750GB drive, please hook it up to a machine of your choice (Windows, *IX, etc.) and use either smartmontools 6.0 output (smartctl -x /dev/sdX where X = a for the first drive on the system, b = 2nd drive, etc.), or a screenshot from HD Tune Pro's Health tab. That may allow me to determine if something drive-level happened that somehow upset the HP unit in an anomalous way. It'll also allow you to decide whether or not you can re-use the drive or toss it. :-)

Thank you. I did just that, and attached it. How am I looking? Drill holes and discard, or put back into the server pool?

kudos:19 | Pretty easy to discern what's going on. Relevant attributes and data:
5 Reallocated_Sector_Ct PO--CK 099 099 036 - 50
9 Power_On_Hours -O--CK 080 080 000 - 17583

197 Current_Pending_Sector -O--CK 100 100 000 - 1
198 Offline_Uncorrectable ----CK 100 100 000 - 0
199 UDMA_CRC_Error_Count -OSRCK 200 200 000 - 0
SMART Extended Comprehensive Error Log Version: 1 (5 sectors)
Device Error Count: 4
The drive has bad sectors/LBAs. Some have been remapped, others have failed remapping. Some are still pending re-analysis for remapping. Many of those have been tracked by the SMART error log as well. The 4 in the error log are for *writes* which failed, which indicates something more sinister. The high-fly writes indicate that there is probably something mechanically wrong with the drive as well (very likely a pair of heads are incorrectly aligned or are loose/unaligned in some way).
Simply put: if this drive is under warranty, zero the drive (you can use HD Tune Pro or dd for this), and RMA it. The SMART attributes will look quite different after you zero it, but that's no reason to keep using the drive (trust me!). It has hard evidence of sector-level issues and Seagate should not give you any lip about doing an RMA. If they tell you to run their automated tools, tell them to sod off -- it's not necessary, the drive has developed bad sectors over its lifetime (17583 power-on hours).
If it's outside of warranty, destroy it in whatever way you enjoy. :-)

| Sorry it took me a little bit to get back to the thread -- been busy.
Thanks so much for giving me good information. Drive will be discarded after a few quick holes are drilled through it. As for the warranty, it's complicated: This 750GB drive came preinstalled into the HP MediaSmart. So I suppose I would have to contact HP for support, and I think my unit is out of warranty. I've had it for at least 2 years, probably much closer to 3.
Since the drive can't be put back into the pool, and it's not like a 2TB drive or something, I think I'll just maximize my effort and time and just discard it, rather than hunt down HP/Seagate for a replacement and get aggravated. I'm sure I can find a nice Cyber Monday SATA HDD deal, and if I do, I can throw a decent 3rd drive in there to increase the pool.
Thanks again for the help. It gives me confidence that the drive in question failed, rather than the whole unit. First time ever I had to do something like this, but it worked out pretty well. Data saved, Server Reinstall easy, but a little time-consuming (2-3 hours).
