Issue Description
Copying or transferring files takes unusually long, even between local drives or over a network.
Common Causes
- Slow storage (HDD vs SSD)
- USB port or cable limitations
- Background disk usage
- Antivirus scanning files during transfer
Step-by-Step Solution
Step 1: Identify Where the Bottleneck Is
- Copy a file within the same drive
- Then copy between different drives
- Compare speeds to identify disk or connection limits
Step 2: Use a Faster Connection
- Plug external drives into USB 3.0/USB-C ports
- Avoid USB hubs when possible
Step 3: Disable Real-Time Scanning Temporarily
- Open Windows Security → Virus & threat protection
- Temporarily disable Real-time protection
- Retry file transfer
⚠️ Re-enable protection after testing
Step 4: Check Disk Health
- Open Command Prompt (Admin)
- Run:
chkdsk /f
Step 5: Close Background Disk Usage
- Open Task Manager → Processes
