1. Under Win7, you can use the 3TB in a single partition after installation of a soft Seagate (Pas glop!)
2. After copying of a large number of files, the disc loses the pedals, mix files and end up not remember anything (disk reformatting to be again recognized and "empty" of course!).
The two discs are the same cinoche me.
=> Data Loss (Unfortunately, I had not put as recoverable data overconfident!).
=> Waste of time (When I think of the time I spent in copying DVDs all !!!!).
Suddenly, I find myself with two 3 TB drives I will not use!
A pity, especially as I also have Seagate 2TB that work very well and with whom I never had any problems.
