|
|
|
|
## Solutions
|
|
|
|
### Solution 1: Check USB Device Connection
|
|
|
|
1. **Physically check:**
|
|
- Ensure USB device is plugged into the **front USB port** (not rear ports)
|
|
- Try unplugging and reconnecting
|
|
- Try a different USB device to test
|
|
|
|
2. **Check in DSM:**
|
|
- Control Panel → External Devices
|
|
- See if USB device appears in the list
|
|
- Check if it shows as "Mounted" or "Unmounted"
|
|
|
|
### Solution 2: Unmount USB Device from Other Uses
|
|
|
|
1. **Check if USB is mounted as shared folder:**
|
|
- Control Panel → Shared Folder
|
|
- Look for USB device name
|
|
- If found, unmount it first
|
|
|
|
2. **Check other USB Copy tasks:**
|
|
- USB Copy → Check all tasks
|
|
- See if another task is using the USB device
|
|
- Disable or delete conflicting tasks
|
|
|
|
3. **Unmount manually:**
|
|
- Control Panel → External Devices
|
|
- Select USB device → Unmount
|
|
- Then try USB Copy again
|
|
|
|
### Solution 3: Check USB Copy Task Settings
|
|
|
|
1. **Open USB Copy task:**
|
|
- USB Copy → Select "Copy Button" task
|
|
- Go to "Task Settings" tab
|
|
|
|
2. **Verify settings:**
|
|
- Source: Should be [USB] or specific USB device
|
|
- Destination: Should be valid path
|
|
- Make sure correct USB port is selected
|
|
|
|
3. **Check "Trigger Time" tab:**
|
|
- Ensure trigger is properly configured
|
|
- If using "Copy Button" trigger, ensure button is enabled
|
|
|
|
### Solution 4: Restart USB Copy Service
|
|
|
|
1. **Stop USB Copy:**
|
|
- Package Center → USB Copy → Stop
|
|
|
|
2. **Unmount all USB devices:**
|
|
- Control Panel → External Devices → Unmount all
|
|
|
|
3. **Restart USB Copy:**
|
|
- Package Center → USB Copy → Start
|
|
|
|
4. **Reconnect USB device:**
|
|
- Plug USB device into front port
|
|
- Wait for it to be recognized
|
|
- Try USB Copy again
|
|
|
|
### Solution 5: Check USB Device Format
|
|
|
|
- **Supported formats:** FAT32, NTFS, exFAT, HFS+, ext4
|
|
- **Not supported:** Some encrypted formats, certain proprietary formats
|
|
- Try formatting USB device to FAT32 or exFAT if needed
|
|
|
|
## Diagnostic Steps
|
|
|
|
1. **Check USB device recognition:**
|
|
```
|
|
SSH to NAS → Run: lsusb
|
|
Or check: Control Panel → External Devices
|
|
```
|
|
|
|
2. **Check mount status:**
|
|
```
|
|
SSH to NAS → Run: mount | grep usb
|
|
Or check: Control Panel → External Devices → Status
|
|
```
|
|
|
|
3. **Check USB Copy logs:**
|
|
- USB Copy → Settings → View logs
|
|
- Look for error messages
|
|
|
|
