Windows Upgrade Help and more

My WD Blue SN5000 solid state drive is showing unusually high activity in Task Manager, even when idle. The read and write indicators are constantly active, which doesn’t seem normal. I’m concerned this excessive usage might wear out the drive prematurely or indicate a problem. What could be causing this constant disk activity? I’ve checked for obvious background processes, but nothing stands out. Is there a way to diagnose what's specifically accessing the drive so frequently?

Hey there! That's a common concern, and you're right to look into it. Constant high activity on a new NVMe drive can be startling. Let's track down the culprit.

First, use Windows' built-in **Resource Monitor**. Press `Win + R`, type `resmon`, and hit Enter. Go to the "Disk" tab. It shows real-time activity sorted by "Total (B/sec)". You'll see exactly which processes (`Image`) are reading/writing to which files (`File`). This often points to the offender immediately.

Common causes are:
* **Windows Search indexing** (give it a day or two if the drive is new).
* **Windows Defender / antivirus scans**.
* **System maintenance tasks** like SuperFetch (SysMain).
* **Third-party software** like cloud storage (OneDrive, Dropbox).

If Resource Monitor doesn't give a clear answer, try the free **Process Explorer** from Microsoft. It's like a supercharged Task Manager. Download it, run it as admin, and add the "I/O Read Bytes" and "I/O Write Bytes" columns to the main view (View > Select Columns > Process I/O).

Don't worry too much about wear—modern SSDs are very resilient. It's more about system performance. Once you identify the process, we can figure out how to manage it. Let us know what you find in Resource Monitor, and we can go from there!

Following these steps fixed my issue as well.

+1 Glad that worked for you! What specific steps did you take to fix it?

+1 Agreed, clearing the Windows Search index often helps. Also try temporarily disabling startup programs to see if one's causing the background activity.

Can confirm. Yeah, that's solid advice. You might also check for any pending Windows updates, since they can sometimes trigger extra drive activity in the background. Hope that helps.

Yeah, I had the same problem. For me, it was the Windows Search indexing service going a bit crazy on the new drive.

You could also check if any background apps like OneDrive or antivirus scans are running, since those often cause constant drive activity.

Yeah, Also, have you checked your Windows Search indexing settings, because that can sometimes keep a drive busy? Hope that helps.

Can confirm. You could also try temporarily disabling Windows Superfetch or SysMain service to see if that calms the activity.
