Thanks. I ordered a few of the 4TB Hitachi NAS drives. Really appreciate the input.

Is anyone using Enterprise-Class drives--or this just way overkill?

I have an Unraid system running 7x2TB Western Digital Caviar Black Models. My unraid is set up in the AVS10 unraid server with space for (10) 3.5" drives and (4) 2.5" drives (currently have an old 80 GB SSD running as a cache disk in one of the 2.5" slots. It has been running 3 years or so with the WD Black drives, but recently started to have a few of the disks show signs of beginning to have problems (Smart issues like offline_uncorrectable and multi_zone_errors). So far they are small, single digit type errors, but would like to start systematically replacing a few of these disks with larger 4TB versions. Performance is an issue for me--so I have traditionally stayed away from the 5400/5900 RPM disks. I also leave my disks spinning 24/7 as one of the main uses for the unraid is serving content to my HTPC and Extenders (Sage TV with (3) HD 300 extenders). However, I am open to looking at the these if the collective knowledge on the forums pushes me this way.. Anyone using the Western Digital Re "Enterprise class" drives? http://www.amazon.com/gp/product/B0090UEQ8I/ref=s9_simh_gw_p147_d0_i4?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=03YH0ZVWE3660F7GS2SF&pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846 I like the 5 year warranty--and cost is not really a major concern if I get a more reliable/better warrantied system (though I obviously don't want to throw money away). Or should I stick with the WD Reds/Seagate NAS drives? Thanks in advance for any guidance.

Thanks. I ran --rebuild-tree. I took over 5 hours (2TB drive) but I can now access the share drive. Had about 6GB of data in the lost+found folder, so not sure what to do with that other than ignore it for now. Is there anything else I should run/do now? Parity check shows good with no errors.

One more thing. I added the cache drive a few days ago. In order to troubleshoot, I unassigned the cache drive from the array. The Share now has a green dot next to it in the unraid/shares menu.

Ran reiserfsck on /md1. Output file scares me... Says 16 found corruptions that can only be run with --rebuild--tree Based on the reiserfsck tutorial page, I need some guidance. screenshot of the telnet session/results attached.

Thanks Totally telnet/Linux noob. Do I run it on /md1 (disk 1) or what that be my parity drive and I run it on /md2 ?

Saturday Morning Bump. Any help is appreciated is resolving this issue. Thanks.

I purchased a new AVS10 server and migrated my old drives to the new server. 6 drive system (Parity + 5x2 TB drives). I have run the Permissions Utility. However, I cannot access certain folders that reside on disk 1. It appears I can browse all folders/files on other disks--but any folders which contain files that reside on disk 1 results in a Windows error. I have re-run permissions, no change. I re-checked parity (although no errors were showing), no change I went so far as to replace disk 1 with a spare and rebuild the array, no change. In running the Permissions utility, it seems to take 2-3 hours to go through disk 1, but the rest of disks are much faster. This drive does have the most data on it (+/- 1.4 TB on a 2 TB drive). On the Shares page (browsing to //tower), there is an "Orange Dot" next to the share. If I click the file folder next to the share, I can see all the files which should be present (including those which reside on disk 1). I am at a loss. I use this Unraid Share as Storage for Media Files to serve to my HTPC (running Sage TV). All movies/music/pictures which reside on disks 2-5 are visible to Sage (utilizing smb filepath referencing the shared unraid folder). Nothing on disk 1 is visible to Sage. Any help/ideas are appreciated.

THANK YOU. Your post triggered me to re-look at the BIOS settings. Somehow it changed during the power outage. All is well again after a simple reconfig of the BIOS

BIOS is set to boot from Removable Drive (same setting that has worked the past few years). I think there is something wrong with the motherboard chipset--it won't do anything and the same Unraid USB drive boots in my other desktop computer without issue. Thanks

Thank you for the help....unfortunately no go. I ran chkdsk on the USB flashdrive. All good. Reran makebootbale.exe Still nothing. I then download a new version of unraid to another usb. Went through installation and still no go. I then put the original USB flashdrive in another computer (desktop PC). Everything booted fine and I got to the tower login prompt. So, I am down to a motherboard/USB loading problem. Nothing wrong with the flashdrive.

Does it make sense to just reinstall Unraid on the flashdrive? I have my drives labeled--so I know which one is the Parity drive vs. data drives. If so, should I upgrade to 5.0? If anyone can point me in the right direction, I'd really appreciate it. I am very nervous about losing all of this data, so I don't want to do anything that brings me past the point of no return. Any other ideas/suggestions for the recovery (or links)? Thanks again for the assistance. Really great forum/community.... Chad

Unfortunately no. No backup at all of the flash drive.

More info: the LED on the USB Flash Drive does Light up a few times upon power on. Could I have a bad config file on the USB drive? I made copy of the contents of the USB drive--but not sure if that would help troubleshoot (or if I am supposed to post it)? Thanks Chad
