I have a 500 gig Seagate Free Agent external hard drive that I am having problems with. The problem is that the amber light on the hard drive comes on solid (bright) at initial start up, but then goes dim then bright, dim, bright etc....

most of these external hard drive units work with a 12V 3 amp DC power supply like this one
OEM AC POWER SUPPLY SEAGATE 9NK2AE 500 Free Agent HDD

Make sure you get the correct power connector for your country.

Hi,
Have you tried uninstalling your seagate free agent software, restarting your computer and installing it again?

Do a FULL POWER DOWN Reboot. and try a different USB outlet in the PC... same Laptop to see if it is in your PC that is causing the problem.
Note: Most of those Drives do stop unless they are connected to the PC... energy savings.
If that didnt work... you could have a failed drive. Seagate should help you do some diag if it is in warranty... typically 3 years.

the soft ware that comes with it will also be erased, as it is a windows based identification,seagate free agent has mac utilities on its site, try to find out on www.seagate.com. you will find one for mac format and mac installation .

You better check with the Seagate people. This seems to be a problem with the casing. And since you're under warranty, you can get a replacement.

It you are using the notebook, this may be the solution for you

DO NOT buy a Seagate freeagent drive under any condition if it comes as a gift return it or re-gift to some one you don't like. Like so many others my 500GB external drive just quit working. Has only been plugged in about 6 times and then back into a cabinet to keep safe. In 10 years between 2 workstations 3 laptops and 4 external drives. The only drives that have ever gone bad are the Seagates and newer Maxators. I still have 4 Western digital drives that still work and get used in an external case for back up. They have never failed. Seagate should be responsible for data time and mental anguish.

Your computer must have a firewire connection.
