Need to repair current pending sector count
Hello, suddenly one of my MyBook exposes SMART warning C5 Current Pending Sector Count - 200 / 100 / 0 / 1. Is this a dangerous warning? Is the drive going to die soon? Can I fix it somehow?
- Question from WD Community
"Current Pending Sector Count" is a critical S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) parameter that indicates the number of unstable sectors on the disk drive that are yet to be remapped or reallocated.
If you’re getting a SMART warning with pending sectors, that typically means your disk can’t (or isn’t) reallocating sectors correctly. This disk can probably fail hard at any time.
β How to check the health status of your hard drive?
CrystalDiskInfo is a tool that is used to monitor the hard drive and show the health status of the hard drive. You can download the CrystalMark website and use the free software on Windows to check your current pending sector count.
β Should you replace your hard drive if it has pending sectors?
It really depends on how much you value your data and how promptly you can respond to a disk failure situation. Typically, a drive with pending sectors is no longer suitable for continuous use. If you are using this drive for non-critical purposes and have backed up all of the data on the drive (or the data is not critical), you can continue to use this drive until it dies.
If your primary boot drive or media storage drive has hung sectors, I strongly recommend replacing it as soon as possible in case a random failure occurs at any time, causing unnecessary trouble and damage.
The value of current pending sector count could be 1, 2, 8…100, 200, etc. Regardless of the value, Current Pending Sector Count repair should be your priority. Continue reading, and you can find the most effective methods to get rid of this trouble.
If you receive Current Pending Sector Count caution, what you immediately need do is to keep the data on the hard drive safe. Before you try the following methods, you would better backup your important data on the affected hard drive immediately to prevent further data loss. Then you can try to run CHKDSK command to check the disk, make the disk wiped with zero, and replace the affected hard drive with a new one.
The chkdsk command can inspect all sectors on the hard drive for the read/write operations. If some sectors don’t respond to the request made by scan, the chkdsk command can mark them as bad sectors and reallocate them. You can run this scan to see if it can work to fix this issue. Here are the detailed operations.
1. On your Windows 11/10 PC, Open Command Prompt by typing cmd in the Windows search box, can select Run as administrator.
2. When the command prompt window appears, type the command chkdsk e: /f /r X and hit Enter to continue. (e: refers to the letter of the drive you wish to scan.)
3. Then type Y to continue the process.
4. When the operation is completed, restart your PC, and run CrystalDiskInfo again to check if the current pending sector count 100 caution still exists.
However, using CHKDSK utility is a temporary fix and it is better for you to change the storage drive to avoid severe data loss disasters. Before you change a new hard drive with the failed one, you need to do a disk wipe first.
A rise in "Current Pending Sector Count" may indicate unstable sectors on the disk drive. If this value increases over time, or you receive a caution from a S.M.A.R.T. scan, you should stop using the affected disk to prevent further data corruption and continue using it only after you have repaired the damaged sectors by secure erase it.
To achieve this goal, you may need a professional disk wiper. Thankfully, there is one can be your worth-trying choice that called AOMEI Backupper Professional.
