This is normal for Lacie. I've dealt with them in the past. They are a premium repackaging outfit of some of the lowest grade hardware you can get. They used to prey particularly on Mac users in the early 00's.

However, you should have backed up your stuff in more than one physical place and never assumed that the disk was entirely reliable.

Buy a quality drive enclosure and a quality hard disk, put them together yourself and make sure you have a half decent backup strategy.
