I have a Dell Demension 2100 I've had for a number of years. Over the years it became really slow and I felt it was completely "junked" up with needless things I'd accumulated over the years. I chose to have my hard drive completely wiped out and reinstall my operating system. First time I had no trouble reformatting and getting back on track. A while later, I chose to do this again. This time I get an error stating "error formatting hard drive". I haven't fooled with the computer in a few months and have since just purchased a new laptop. Now I would like to fix the computer and give it to a friend who is without. The error message does not specify exactly what the error is. I know nothing about computers. When I begin formatting I'm asked if I want to dedicate all memory to the operating system...I say yes.....Don't know. Anyway...is there something else I should be doing or is the hard drive bad and need a new one? Thank you in advance for any advice!!
