S.M.A.R.T. disk errors since firmware update!
HELP!
On November 5th I updated the firmware on my RND2000 (10/2010, see setup below) from v4.1.6 to v4.1.10. After the successful update my internal disk #2 suddenly starts turning out more and more SMART errors (reallocated sector count):
- Previous sector count (dated June 5th 2011): 0 -> 851
- Sector count dated November 5th 2012: 851 -> 1375
- Sector count dated November 8th 2012: 1375 -> 1380
- Sector count dated November 9th 2012: 1380 -> 1391
"Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk."
Here's the SMART log of both disks (sorry in Dutch):

What should I do?? First I think I'll disable the power timer and shut down the system until I find a solution. I know 1391 sectors don't represent a great deal in actual disk space, but I bet (a lot) more is coming my way. :(

- What you need to do is replace the disk. The normal recommendation is to replace when the count reaches 50.

Thanks Stephen, I guess that's the only way out.
Now comes the task of choosing a replacement disk (or two). Could it be that certain disk models are affected by the power timer in my ReadyNas? For instance, would it be better if I keep it running 24/7 instead and enable spindown of the disks?- Some disks draw more power than others, though I haven't seen much information on how that effects the ReadyNAS power timer (and disk spin up). There are some posts that suggest that Netgear doesn't spin up all the drives simultaneously in some ReadyNAS models (they stagger the spin-ups).
I have started buying WDC Red Drives as replacement drives myself, so far I have been quite happy with them. - I've had issues with an NV+ 4.1.10 and an x86 4.2.22 upgrade recently both involving increased "SMART errors" and disk failures.
3rd line support told me that 4.2.22 reports more SMART warnings than previous versions and that it's only telling you about stuff that was already happening with previous OS versions but simply wasnt reported. I assume the same may be true for the 4.1.10 upgrade on the NV+.
What kind of disks are they? All of my problems were with Seagates. I've now switched to using Western Digital REDs....
Interesting comment from StephenB re the power draw. I've seen "Spin Retry Count" errors and "Command Timeout" errors which I've never seen reported before (and which the drives simply didn't have bad numbers in their SMART data before) and I have read that both could be due to power supply and controller issues - though Netgear support seem to prefer to suggest that all SMART errors can only be down to bad disks.
My current pet theory is that these latest OS updates have changed how the disks get spun up and spinning up whole arrays of some kinds of disks causes too much power to be drawn and this is causing failures... - Considering the fact that both my drives will be replaced soon by probably a pair of WD Red WD10EFRX, and that I don't care much about the difference in power consumption (at least for now), what would be the MOST HDD-FRIENDLY (long life) setting for the power timer- and disk spindown-option? Both enabled or disabled, or one of both enabled?

Spinning the disk creates some wear per hour of spinning, spinning it up and down creates its own wear. What doesn't seem to be available is the balance (how many hours of spinning equates to one spin down / spin up cycle).
Personally I leave the NAS running 24x7, and have a relatively long spindown timer (no more than 12 spin downs per day). However, lots of other folks use different strategies.
