What is not so good about diskpart is that it didn’t tell us the disk’s serial number. The drive letter X and volume label show up in the disk details so we know which partition is on the disk. Volume 0 X Toshiba4TB NTFS Partition 3725 GB Healthy Volume # Ltr Label Fs Type Size Status Info We run diskpart and then select disk 0, then lookup the details: DISKPART> list diskĭISKPART> detail disk TOSHIBA MG03ACA400 ATA Deviceĭisk ID: Ideally you will have tagged each disk in your server with the serial number so you know which one to pull out if need be. Using diskpart.exe, or if you have a full user interface, Windows Disk Management, you can check on each drive and see which partitions are stored on which drives. Which hard drive is it?īefore we dig further, we need to know where (on which disk) each partition is stored. A much more detailed report can be obtained by using the disk’s SMART mechanism. Step 3: Check internal hard drive error reportsĪ simple way to check all drives is to run this command: wmic diskdrive get statusīut you will likely find that it’s a little too primitive as it only shows “OK” for each drive listed without any additional information. When these are all used up, however, the drive will start reporting the issue to the operating system in the form of a read or write error hence, the need to check the Event Viewer logs. Modern drives ship with extra space to accommodate a certain number of bad sectors. Therefore, even a successful /b scan with no bad sectors reported may hide the fact that some sectors were bad and were safely replaced by the drive internally. By scanning every single sector, the disk is forced to check on each sector, which is normally not done. Note that the disk may report no errors even if there were bad sectors, because the disk uses self repair mechanisms when you actualize sectors. The /b parameter tells chkdsk to scan and test every single disk sector. In the case of the system boot disk, it will require a scan before Windows completes booting: chkdsk D: /b If you suspect the disk may have bad sectors, use the following command, but it will require the volume to be taken offline. To check for file system consistency without downtime, use: chkdsk C: The file system may become corrupt for many different reasons, the most common one is a sudden loss of power, blue screens, or driver bugs. The good old chkdsk command in Windows was brought to Windows from MS-DOS, and that for a good reason. Step 2: Check for file system corruption and inconsistencies Before we get to internal disk checks, there are more common issues, such as file system corruption. Ideally you would want to catch a failing drive long before that, and below we have a method of doing exactly that. Note that many disk errors, as well as bad sectors, don’t show up in Windows until the disk has exhausted its ability to self repair. Unfortunately the term ‘warning’ was not chosen carefully, they should have named them ‘errors’, since in our experience a logged disk ‘warning’ is really nearly always indicating a hardware fault, such as a bad sector. If there are serious disk issues simmering, many times you will find disk warnings in the event viewer logs. Step 1: Check event viewer logs for disk warnings After all, most servers are “always-on” with only few opportunities to take a server offline however, there are several ways you can check on your hard drives without having to shut down the server or interrupt its services. Especially if you are using a Windows Server in a production environment, you would definitely want to check the health of your hard disks without downtime.
