I have a Firewire drive plugged into a firewire port via a PCMI card why doesn't Win 7 let me see the drive? In device manger it shows the device but will not let me see it in my computer/explore or even mount it?

If you are unable to see or access a Firewire drive that is connected to a firewire port via a PCMI card in Windows 7, there are several reasons why this might be happening. Here are some troubleshooting steps you can try to resolve this issue:

1. Check Drive Management:
- Open Disk Management in Windows by right-clicking on "Computer" or "This PC" and selecting "Manage."
- Look for the connected Firewire drive in the list. It might be listed as unallocated or without a drive letter.

2. Assign a Drive Letter:
- If the Firewire drive is detected but doesn't have a drive letter, you can assign one:
- Right-click on the drive in Disk Management.
- Select "Change Drive Letter and Paths."
- Choose "Add" and assign a drive letter.

3. Update Drivers:
- Ensure that the drivers for both the Firewire card and the hard drive are up to date. Outdated drivers can cause compatibility issues.

4. Test the Firewire Port and Cable:
- Make sure that the Firewire port on the PC and the cable connecting the drive are in good working condition. Try using a different cable or port to rule out physical connection issues.

5. Compatibility:
- Confirm that the Firewire drive is compatible with Windows 7. Some older drives might have compatibility issues with newer operating systems.

6. Power Supply:
- Ensure that the Firewire drive is receiving adequate power. Some Firewire drives require external power adapters to function correctly.

7. Drive Formatting:
- If the drive is not formatted correctly or is using a file system that Windows doesn't recognize, you may need to format it. Be cautious as formatting will erase all data on the drive.

8. Data Recovery:
- If accessing the drive is crucial and you are unable to resolve the issue, consider using data recovery software to retrieve important files before attempting more drastic measures.

By following these steps, you should be able to troubleshoot and resolve the issue with accessing your Firewire drive on Windows 7.
