Disk Failing
HI All,
I have a ReadyNas Duo, running 2 x 2TB drives in x-raid configuration. For a while now I have been getting the following type notifications.
"Access to the disk on channel (??) is producing I/O errors. Although the array is still redundant, please replace this drive as soon as possible, as it is likely to fail soon."
"A SATA reset has been performed on one or more of your disks that may have affected the RAID parity integrity. It is recommended that you perform a RAID volume resync from the RAID Settings tab ( accessible in the Volumes page => Volume tab in FrontView ). The resync process will run in the background, and you can continue to use the ReadyNAS in the meantime."
Also occasionally it will just become non-reachable and unresponsive. It will disappear from RAIDar and the only way to get it to come back up will be to do a power down. The blue button on the front will become unresponsive.
I am running the latest Raidiator version 4.1.10
I am sure one of the disks is failing or perhaps incompatible, although both were purchased off the recommended disk recommendations. I have had a look at the SMART stats but am not sure what is out of the ordinary.

Am happy to take a disk out and replace it, but not sure which is the faulty (or perhaps both) disk. Or perhaps there is a bigger problem with the unit, either way, at the moment the NAS is as good as useless to me.
Any help or advice from anyone would be greatly appreciated.

- The WD disk is failing, I think. You could hook the drive up to an internal SATA port in your PC and test it using WD LifeGuard Diagnostics.
Also note that there is a firmware update available for your SeaGate disk. See http://www.readynas.com/forum/viewtopic.php?f=24&t=64510
Before doing a firmware update on the SeaGate disk you should backup your data. You would need to hook the drive up to an internal SATA port in your PC to do the upgrade. - Hi, thanks
OK, so the WD disk is in slot 1 and the seagate in slot 2. So should I power it down and remove the WD from slot 1 and then if I power up will it operate as if only 1 disk is in the enclosure. I should then be able to buy a new disk for slot 1 and that should sync when inserted in. Once that is done I should try update the seagate FW and happy days?
Or should I move the SG over to slot 1?
Sorry for all the questions, want to try and minimise the impact of this, really don't want to lose all the data. Have tried to backup everything, but because of the errors, it seems some files crash the system when I try to get at them. - I would leave the SG in slot 2. Ideally you would just get a new drive, and hot-swap it (in slot 1).
As far as the seagate firmware goes, at any time you can power down the NAS, remove the drive, update the firmware on an PC, then reinstall the drive and power up the NAS.
Do a backup first - before replacing the WD or upgrading the SG firmware. If you haven't saved the config file lately, do that also.
