Telling the story is not the same as giving the facts. The more information (facts) you give and the more accurate the information, the better we can understand and offer assistance.
..... the (hardly used) hd I wanted to install on has problems.
It has problems?
- no info.

In the electronics?
Really? Which/what electronics?
Remember, we are not there to have a look for ourselves. You must give us accurate information.
