Hi Croth44,
A. How are you trying to transfer files to the external hard drive?
B. Were you able to transfer it earlier?
C. Are you getting any error message?
D. Is your hard drive NTFS formatted?
Let us try the below steps.
Step 1
Try to convert the file system to NTFS and check if you are able to transfer files.
1. Click Start
2. Type cmd in the start search box
3. Right click on cmd from the menu and choose run as administrator.
4. In the command prompt type convert <drive_letter> /fs:ntfs
Step 2Try to break the files to smaller size or shrink the files and transfer the files.
Step 3
Uninstall all USB related entries in device manager.
- Click START
- Right click 'Computer' and select 'Properties'
- On the left hand side, click 'Device Manager'
- Expand the 'Universal Serial Bus Controllers' category
- Right click and uninstall ALL entries listed
- Restart your Computer and check if it works.
I would suggest you to go to your Manufacturer's website and try to install latest drivers for chipset. Make sure you install it in compatibility mode as there are no 64 bit drivers released for Windows 7.
