What's wrong with my hard drive?

[howyoudoing6]

I have a Western Digital 1 TB hard drive and I noticed that it has been running slower than usual and it freezes at times. I used Speccy to see if anything is wrong and some of this information made me wonder if something really is wrong.

Here's what I found.

S.M.A.R.T
01 Read Error Rate 200 (200 worst) Data 0000000002
03 Spin-Up Time 172 (171) Data 0000001117
04 Start/Stop Count 100 (100) Data 000000004F
05 Reallocated Sectors Count 200 (200) Data 0000000000
07 Seek Error Rate 100 (253) Data 0000000000
09 Power-On Hours (POH) 100 (100) Data 00000000F0
0A Spin Retry Count 100 (253) Data 0000000000
0B Recalibration Retries 100 (253) Data 0000000000
0C Device Power Cycle Count 100 (100) Data 000000004E
C0 Power-off Retract Count 200 (200) Data 000000000C
C1 Load/Unload Cycle Count 200 (200) Data 0000000042
C2 Temperature 121 (107) Data 000000001A
C4 Reallocation Event Count 200 (200) Data 0000000000
C5 Current Pending Sector Count 200 (200) Data 0000000000
C6 Uncorrectable Sector Count 100 (253) Data 0000000000
C7 UltraDMA CRC Error Count 200 (200) Data 0000000000
C8 Write Error Rate / Multi-Zone Error Rate 100 (253) Data 0000000000
Temperature 27 °C
Temperature Range ok (less than 50 °C)
Status Good


The top status worries me being 200 at worst and mine is at 200.

200 reallocated sectors.. yeah she's dying on you.

The Current and Worst attribute values are normalised "health" scores. A score of 200 is perfect.

You should be looking at the raw Data (eg 0000000000) for the actual number of reallocated sectors. In your case there are zero reallocations.

In short, you SMART report looks very good. However, SMART doesn't always identify every problem. For example, if there are "weak" sectors, then the drive may require several retries before it can read them, but they won't necessarily show up in your SMART data.
