Windows 10系统持续磁盘访问导致副硬盘无法休眠的问题咨询

Hey there, let's work through this issue together! First up, some background activity on secondary drives right after a fresh OS install isn't totally out of the ordinary—but if it's stopping your drives from ever going to sleep, we need to figure out exactly what's causing it.

Common Reasons for This Behavior #

• Windows Search Indexing: Fresh installs usually kick off a full index of all connected drives to build the search database. This can run in the background for hours (even days, depending on how much data is on the drive) and will keep accessing it periodically. You can test this by opening Services.msc, finding the Windows Search service, and temporarily stopping it to see if the drive finally sleeps.
• System Restore Protection: Windows might be creating initial restore points on your secondary drive if system protection is enabled for it. Head to System Properties > System Protection to check if the drive has protection turned on—this could be triggering regular access.
• Antivirus Full Scans: Default tools like Windows Defender will run a full system scan right after installation, covering all connected drives. This background scan can keep the drive active until it's completely finished.
• Drive Integrity Checks: Windows' own chkdsk or third-party hardware monitoring tools might be running in the background to verify your drive's health post-install. Check the Event Viewer for disk-related events to confirm if this is happening.
• Stuck/Misconfigured Processes: Even a fresh install could have pre-installed utilities or bloatware that's repeatedly accessing the secondary drive. Your ProcMon tool is perfect for pinning this down—look for repeated read/write operations targeting your HDD in the logs.

Is This Normal? #

If the activity dies down after a day or two (once indexing, scans, and initial setup tasks wrap up), then it's likely just standard fresh-install behavior. But if it goes on indefinitely, that's a sign something's stuck or misconfigured and needs fixing.

Using ProcMon to Diagnose Further #

1. Filter ProcMon results to only show operations for your secondary HDD: Use the Filter option, select Path, and enter your drive letter (e.g., D:\*).
2. Identify repeated processes: Note the process names—for example, SearchIndexer.exe ties to Windows Search, MsMpEng.exe is Windows Defender.
3. Dig into process details: Right-click a process in ProcMon and select Properties to see exactly what files or folders it's accessing on the drive.
