Ah, that sucks
I hope you didn't lose any data, and I hope the refurb drive lasts longer than the last one!
Always make backups though. Never trust any hard drive, or any form of drive for that matter with important data. Its just not worth it, because if it goes, its most likely gone.
In the end, to the computer, its just a bunch of 0's and 1's, but to you, the data could mean the world.
