I just returned a Seagate (assembled in China) due to an internal connection problem. I'm sure the drive, which was made in Thailand, was OK but I had to apply considerable downward pressure to even get power to the drive. The interconnect module which unplugs seemed to be the problem. I'm willing to pay a couple bucks more for something that works.
I had the same problems with several external Seagate drives - made in China - and want also to buy a hard disk made in another country than China. Which manufacturers come into question?
