Again. Never found it to be the drive.
I've found issues with power, encoding, the format of the drive so if your Seagate does not work then it's safe to write the issue is not what it seems.
I find folk upset over this area because folk that have been around know that you can't solve this by changing the drive. You solve the power issue if the owner is using USB power, you solve the format issue and you solve the encoding issue.
With no less than 3 areas to work, you can see why picking the right drive is not the answer.
