Dropped object on Laptop, hard drive error next day.

I don't know how a hard drive works internally, but is it possible that dropping a heavy object on a laptop - in which caused a drive to have an error - mean the drive is competently damaged beyond repair?

Or is it possible this error could be corrected by simply reformatting the drive, and reinstalling windows? Or would you normally have to dispose of the drive completely?


Here is the long story version;
I was moving a box on a shelf and a large object fell on top of my notebook, which was running. It hit the plastic bellow the keyboard pretty hard. I was like, "oh no!" but right after it happened it seemed nothing was effected. Everything worked fine. However, hours later after i restarted, i discovered that in the Boot up, it said that one of my disk reported an error occurred on the second disk. ( The internal disks are in RAID0) .
I assume that this is not a co-incidence and that the object that dropped on the computer caused this to happen. I was able to get into windows, but not able to back up all data without the computer freezing and restarting. At some points the internal drive made a noise that was not normal. I decided to do a reformat of the drive and now the Boot up no longer says "an error occurred" on that one disk. It now reads "normal".

In where you do your defrag there's something called "error checking". Select it....... tools/error checking......... put a check mark in both boxes and hit ok..... do a re boot and let it do it's thing.
