My new ultra-silent & ultra cool 1TB drive
Some years ago, I've found a few bad sectors on my WD10EARS Caviar Green drive not too long after purchasing, but I decided to simply partition around it. Actually, I can't remember now when that was, but I've either used up a major part of the disk and had nowhere to back up everything by then, or I've deliberately planned to extend the warranty by a replacement... The original purchase came standard with 3 years of warranty.
The drive didn't store too precious data in general, but no attention was given to the issue for years. The fault seemed to propagate by a few dozen bad sectors over the allocated 1GB margin, injecting a few macroblock errors to 5 of my unimportant home recordings. Actually this spreading was really slow, as occasional slowdowns were indeed experienced when randomly accessing some of the files in the past, but the fix was never a priority.
For serious use, I'd like to point out the importance of data scrubbing for protecting against bit rot, which is very easy to set up and there are a lot of solutions. What's the purpose of hardware ECC and SMART if you never update (or monitor for that matter) its variables?! Additionally, it generally gets more and more difficult to restore data as time goes by, so it's best not to delay detection until the next random access (when you actually need the data).
Anyway, now that I have some more disks, I've gathered the willpower to have this one fixed. I've returned it on the 22nd of January with detailed SMART event and attribute logs and sector mapping to the local shop. I've simply used smartctl -x (plus dmesg, smartctl -t long, dd, etc.), and haven't even attempted to play with the factory repair utilities. I've finally got a call on the 13th of February about authorizing a replacement, and had time on Friday to get the drive.
Here's some more information I've gathered about the new disk (improvements highlighted):

Here's some more information I've gathered about the new disk (improvements highlighted):
- 2 years of warranty (as is standard today)
- Model number WD10EZRX, advanced format
- Speed: SATA 6Gb/s, 150MB/s sustained, IntelliPower RPM (probably 5400), 64MB cache
- Power: 1.1A @ 12VDC peak (startup), 3.7W read/write, 2.1W idle, 0.4W standby
- Acoustics: 21dbA idle, 22dbA quiet and performance seek
- 0.45kg weight, non-operating shock resistance 350Gs, 300000 load/unload cycles
- Single platter (inferred from power, weight and speed figures, additionally found in RML527's platter database)
