Thank you for not following my instructions (I asked you to insert the data into a [code] block to retain formatting). I will do my best. :P
SMART attributes show the following:
1. Drive has been in use for 15368 hours, or roughly 640 days, so a little under 2 years. Drive is 3.5" form factor.
2. SMART attribute 1 indicates the drive does have some minor issues re-reading certain sectors (note: not "reading", but actually "re-reading" in error conditions).
3. SMART attribute 5 indicates you have a total of 452 LBAs which have been remapped. This is a 512-byte sector drive, so that means you've lost a total of 231424 bytes of data over time. Which data was lost/what files were impacted is impossible to tell without a checksumming filesystem (ZFS, Btrfs, etc.).
4. SMART attribute 196 indicates there have been a total of 66 reallocation events, whether successful or failed. This number is a little hard to describe, since you might expect it to be the same (or greater than) what's in attribute 5. The tricky part about this number is that it actually fluctuates; it's a counter, but it doesn't increment -- it can be any value. It will go back to 0 when the drive has finished dealing with reallocation analysis.
5. SMART attribute 197 indicates you have 1 LBA which is "suspect", thus presently unreadable. Any attempts to read data from that LBA will result in an I/O error. The only way to get the drive to determine if the sector is bad is to initiate a write to the LBA, which will naturally cause it to lose its contents. So consider this another 512 bytes of data loss (total lost bytes at this point is 231936)
6. SMART attribute 200 indicates the drive is beginning to show signs of physical media wear or has physical/magnetic problems with the substrate layer. This affects writing especially. The drive has seen worse conditions in the past (current adjusted value is 197, but sometime during its lifetime has gotten down to 172).
7. Your SMART error log indicates a total of 119 events pertaining to errors (sector reads/writes which failed, or other anomalies). It looks like these have been gradually accumulating over time.
Due to the hard disk vendor choosing threshold trip values which are extremely lax, no SMART attributes have tripped, thus the overall SMART health value of the drive is OK/GOOD.
I could not give half of a rat's butt what Western Digital's own test tool says about the state of your drive -- that tool is only sometimes useful. It can never, EVER replace that of an actual human being when it comes to attribute analysis.
Overall advice:
Replace the drive. If it's under warranty still, do an Advanced RMA with WD (this ensures you get back a new drive first, which you can test fully -- let me know if you want me to point you to the procedure used to do this; it's actually much easier in *IX OSes than on Windows). Regarding the replacement: if you submit an Advanced RMA via their website, they will not require you to give them a "WD Diagnostic test code" -- you just simply pick "Bad sectors" as the reason and that's it.
If it's not under warranty, buy a new drive. Please avoid WD Green drives or any WD drive with "-GP" in its name at this time. You're free to purchase any other brand you wish, though I do not recommend Seagate's current models since they tend to also aggressively park their heads (and without any way to track it; you'll just hear it going "thunk" randomly). If choosing Samsung, please be aware of catastrophic SMART-related firmware bugs that can result in data loss (there are firmware patches that fix this). |

Thanks kindly. It's out of warranty according to the serial number and the WDC Warranty page...
I was thinking of picking up these Seagate but I've had a few problems with their external drives and also note your remarks on them...
Again many thanks... |

I did install smartmon ver 5.39 from your link.
I'm running natty (Zorin OS 5.2 based on Ubuntu 11.04)... |
