Terrible (edit your comment) Add link

2 months ago.

Died in less than a year. Return process took over a month and they want you to waste your time trying to troubleshoot even though it is completely dead. I think the whole process took abut 10-12 weeks and I lost everything as I thought the drive would last me at least 2 years.
