A few days ago I thought it would be a good idea to check the status of my HDD’s, so I installed HD Tune and shockingly one of my drives (WD30EZRX) reported a SMART warning.
The warning was coming from the Current Pending Sector (C5), which had a value of 1 in the data column.
So I googled a little bit about it and I read that it might be a good idea to install the WD Diagnostics tool and run the extended test. When I opened WD Diagnostics however, I noticed it said PASS next to the HDD in question. All values seemed to be good, but I thought it would be a good idea to run the extended test anyway and see what would happen.
After finishing the test, it said it completed the test successfully. HD Tune still reported the warning though and WD Diagnostics tool still says PASS.
Next up, I installed CrystalDiskInfo and Speccy. Speccy reported that the HDD is in good health, while CrystalDiskInfo gave a warning for Current Pending Sector (C5) and additionally Uncorrectable Sector Count (C6) with a value of 1. I also noticed that Write Error Rate (C8) has a value of 1, but is not marked as a warning in any program. I do have a feeling it might be related to the C5 and C6 warnings though. I had a few power outages the last few days, so maybe it just screwed up somewhere?
Anyhow, I tried a few solutions to solve the problem:
Run chkdsk /f /r - No errors found, everything was fine
Run HD Tune Error Check - No errors found, in both the long and quick version
Backup the drive and run a zero format using the WD Diagnostics tool - this is about 2 days later from the initial check, since all the tests take about 6 hours to complete…
The last option did solve the C5 error. The value is 0 again and both HD Tune and CrystalDiskInfo report it as OK. Also no sectors had to be remapped, since the reallocated sectors count is still 0. Which should have been 1 (from what understand), if something had been wrong with the pending sector.
Now for the current problem, I kind of expected the zero format to also solve the C6 warning in CrystalDiskInfo (all other programs report the disk as healthy now). It didn’t however, as the value is still 1 and marked as “caution”. Should I worry about this? Is there any way to also fix this value? Currently I’m running another extended test, but I doubt it will do anything.
Here is a screenshot of the current SMART status in CrystalDiskInfo:
