Windows 10连接第二块硬盘时无限转圈无法启动求助

Hey there, sorry to hear you spent a whole day wrestling with this—total mental and physical drain, I’ve been there. Let’s break down why disconnecting your WD HDD fixes the boot issue, and walk through actionable steps to get everything working together again.

First, quick recap of your setup to make sure we’re aligned:

• System drive: Samsung SSD 840 EVO 120GB (where Windows is installed)
• Secondary drive: Western Digital WD Caviar Blue 1TB (stores all apps, docs, etc.)
• Issue: Boot gets stuck on Windows black screen with loading circle—goes away when HDD is disconnected

Possible Root Causes #

The most likely culprits here are:

• Your BIOS/UEFI is trying to boot from the HDD (which isn’t configured as a boot drive)
• The HDD has file system errors or bad sectors that Windows hangs on during startup
• Leftover boot configuration entries pointing to the HDD
• Loose/faulty SATA/power connections for the HDD

Step-by-Step Fixes #

1. Verify Boot Order in BIOS/UEFI #

This is the simplest check and often resolves the issue immediately:

• Restart your PC and hit the BIOS/UEFI key (varies by motherboard—usually Del, F2, or F10; watch the on-screen prompt for guidance)
• Navigate to the Boot tab
• Make sure your Samsung SSD 840 EVO 120GB is set as the first boot device
• Save changes and exit (usually F10)
• Boot up again to see if the loading circle hang is gone

2. Scan the HDD for File System Errors & Bad Sectors #

Since all your critical data lives on this drive, we need to confirm its health:

• Boot into Windows with the HDD disconnected, then reconnect it (either shut down to plug it in, or use hotswap if your case supports it)
• Open Command Prompt as Administrator (right-click Start > Command Prompt (Admin))
• Run this command (replace D: with your HDD’s actual drive letter):
  chkdsk D: /f /r
• This will scan for errors, fix file system issues, and repair bad sectors. Note: This can take 30+ minutes for a 1TB drive—let it finish uninterrupted.

3. Clean Up Invalid Boot Configuration Entries #

Sometimes Windows holds onto old boot references that cause startup hangs:

• Open Command Prompt as Administrator
• Run bcdedit to list all current boot entries
• Look for any entries that mention your WD Caviar Blue drive (check the device or osdevice fields)
• If you find an invalid entry, delete it with:
  bcdedit /delete {entry-id}
  (Replace {entry-id} with the actual ID from the bcdedit output—e.g., {12345678-1234-1234-1234-1234567890ab})
• Warning: Only delete entries you’re certain aren’t linked to your SSD boot drive.

4. Check HDD Connections #

Loose cables are way more common than people realize:

• Shut down your PC, unplug the power cord
• Disconnect the SATA data cable and power cable from the WD HDD
• Reconnect both cables firmly (push until you hear a click)
• If you have a spare SATA cable, swap it in to rule out a faulty cable
• Try booting again—if it works, the issue was just a loose connection

5. Run Manufacturer Diagnostic Tool #

WD has a dedicated tool to check drive health in detail:

• With the HDD connected and Windows running, download WD Dashboard
• Install and open it, then select your WD Caviar Blue 1TB drive
• Run a Full Diagnostic Scan
• If the tool reports any failures, back up your data immediately (use an external drive) and consider replacing the HDD—drive failures only worsen over time

Hopefully one of these steps gets your system booting smoothly with both drives connected. You’ve already done the hard part by narrowing down the issue to the secondary HDD—now we just need to pinpoint exactly what’s wrong with it. Good luck!
