I have been using a 1 TB Free Agent GO Portable hard drive model STAL1000100 for some time.
I wanted to make a backup, so I bought a second one and connected BOTH drives to my HP notebook PC which has Vista Home Premium.
The system failed to detect the second drive (No drive letter is assigned). I then connected both drives to another notebook, thiis one one running on Windows 7. Same thing. If I plug in either drive alone, each one is detected and works fine, but I need to be able to connect both at once.

I posted the request for help here in the forum only AFTER searching and trying all of the "solutions" listed in the reply post, none of which worked, which is why I posted here. If any of them had worked I wouldn't have posted a request for help here.
Moreover, none of the topics mentioned above address my specific problem that resulted when two identical drives were connected.

I have the same problem with two 1TB freeagent go drives. each one on its own is detected without a problem on any computer. if i plug in both at the same time only the first connected is recognized by windows 7. tried different usb ports and so on. nothing works.
this is really anoying because i need both drives at the same time. never had such a problem with two identical external drives from other brands.
hope for a solution soon!

i found a solution for the problem. the two drives have the same disk signature. you can assign a new disk signature with the windows diskpart tool.
see this guide for details: link

for the freeagent drives with this problem i called teck support and received these instructions.
Thank you for contacting Seagate Technology.
Here are the instructions for resolving a signature collision.
1. Connect all drives.
2. Access computer management (Right-click on computer and select manage.)
3. Select "Disk Management"
4. Go the the bottom of the window that shows disks 0,1 etc.
5. Right-Click on any of the drives that are listed as offline (left column) and select online.
This should force the drive to be assigned a drive letter and make it accessible in windows explorer.
this is for windows 7 x64.
not sure if it works for all operating systems.
