As some of you may be aware, I don’t put a whole lot of stock in the “SMART” feature of hard drives.
Rarely have I had the SMART capabilities of a hard drive actually tell me that the drive was going to fail.
Recently I had an encounter with SMART errors in a totally different way.
Basically, my ReadyNAS NV+ storage server was telling me that “Disk 1” was having problems and might fail soon … but all my tests indicated that the drives were fine.
After a lot of hassle, and going back and forth with Netgear support, I finally figured out the problem.
It started a few weeks ago with an email the ReadyNAS sent
Reallocated sector count has increased in the last day.
Disk 1: Previous count: 671 Current count: 677
Growing SMART errors indicate a disk that may fail soon. If the
errors continue to increase, you should be prepared to replace the
The odd thing was, the SMART information on the drives, that was available via the ReadyNAS web interface, did not indicate any of the 4 drives currently installed had any reallocated sectors.

It’s been quite a while since I upgraded the hardware that runs this (and others) web site.
The warranty on the systems either will be expiring soon or has already expired.
So I bit the bullet and ordered a new Dell PowerEdge T310 server. The pertinent specs are:
- Quad core Xeon 2.66ghz processor
- 12gb RAM
- RAID controller
- 4 x 500gb hot swap drives (configured as 2 x 500gb RAID 1 sets)
The system arrived last week and I got it set up immediately.
I actually ordered the system with only one 250gb hard drive and 4gb of RAM … and upgraded it myself.
A few things annoyed me out of the gate …
In general, I’ve been quite pleased with the technical support I get from Dell’s Small & Medium sized Business division.
They usually adapt quickly to my level of technical expertise and take my word for it when I report a problem. Once the failing component has been identified, they quickly setup the appropriate dispatch to get the problem corrected.
Yesterday, however, was an exception.
