Hard drive problem

[Daniel_482]

hey there, what happens when electricity goes away while your in in process of formatting hard drive by dos command?

Possibly nothing but you're going to have to do it all over again.
Data corruption/loss across other partitions(if there are any more than one)
or
Possible failure of HDD.

If you are formatting the drive, one can assume that there is not data on it that you want/need recovered. You will likely need to restart the format command and consider using a UPS to prevent the system going offline, should the power fail again.

There are cases where a hard drive's heads may get stuck to the platters or firmware issues come as a result of a power failure. But, most of the time, you should be just fine to restart the format and carry on.

+1 on usage of UPS, whether with or without AVR. Wife and I have several in our home, in key areas.
