Honestly - if I'm uncertain, I would try to apply the configuration - worst case, the HDDs go back to warranty exchange making the lack of TLER and become _their_ problem. According to reports, Western Digital WD15EADS 1.5TB Green Power drives firmware manufactured sinde November 2009 does no longer support TLER - and it can not be enabled with the WDTLER.EXE utility. Under the line, it's pure money making - selling the same crappy product prone to massive errors under the hood under to different labels and price tags. Up to a certain manufacturing date and/or firmware version, it is possible to enable TLER on the WDC Green disks: viewtopic.php?f=160&t=22554&p=96477&hilit=WDTLER.EXE#p96477 What is more then obscue in WDC's logic: More and more desktop systems come with RAID controllers, allowing shadowing or stripping of the local disks. The more disk activities there are, the more error recovery takes place - in fact more then what we users experience from outside. Or you do a big backup, or configure Q-RAID on a TS-1xx one day. On a single disk unit, this should not hurt to badly - unless the eror recovery takes that long that the system watchdog is rebooting the QNAP TS.

I have learned now that RAID1 is the wrong solution for me personally, but I am a bit at a loss on how to switch from RAID1 to two single volumes (and then using a remote-replication-job to localhost) without moving all my data to third disk (which I do not have).

However, this does not bother me, since I choose for RAID1 was backup-security only. I guess this is what the WD support person is correctly worried about. And then, it seems, waiting for 2-3 minutes and rebooting the NAS should resolve it, right? Now I understand that such a procedure is totally against the intention of using RAID1, which is high availability, since then the data would be inaccessible until the reboot is finished.

However, as far as I understand the above eMail, the problem only arises once things go wrong. Western Digital Service and Support I have not yet encountered any problems whatsoever using two WD15EADS drives with RAID1 on a TS-219P. If you have any further questions, please reply to this email and we will be happy to assist you further. I hope that we have met your expectations today and that you are satisfied with our service. Though TLER is designed for RAID environments, it is fully compatible and will not be detrimental when used in non-RAID environments. This means that the hard drive will not be dropped from a RAID array. The hard drive will only spend 7 seconds to attempt to recover. Western Digital RAID edition hard drives have a feature called TLER (Time Limited Error Recovery) which stops the hard drive from entering into a deep recovery cycle. Western Digital does not recommend installing desktop edition hard drives in an enterprise environment (on a RAID controller). Most RAID controllers allow from 7 to 15 seconds for error recovery before dropping a hard drive from an array. If a hard drive takes too long to complete this process, the drive will be dropped from the RAID array. Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. This process can take up to 2 minutes depending on the severity of the issue. When an error is found on a desktop edition hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area. This is caused by the normal error recovery procedure that a desktop edition hard drive uses.

If you install and use a desktop edition hard drive connected to a RAID controller, the drive may not work correctly unless jointly qualified by an enterprise OEM. Each type of hard drive is designed to work specifically in either a desktop computer environment or a demanding enterprise environment. Is this NAS device working on a RAID? If so, Western Digital manufactures desktop edition hard drives (Caviar Green) and RAID Edition hard drives. Code: Select all Thank you for contacting Western Digital Customer Service and Support.
