I Have a pile of DELL computers that I have been refurbing and donating or selling for cheap. My personal computer was crashing so I decided to build myself a different one from the pile. I picked a Dimension 4700 it has a 3.4 processor, an 80 gig SATA HDD, 2gigs RAM, 2 DVD R/R 2 video cards for the 3 lCDs, sound card. original paperwork and CDs So figured it was worth my time. I loaded windows, office, antiviruse spyware, all my mantinace programs. And was just ready to transfer documents I wanted to keep from old computer when started thinking I needed more space. I found in one of the computers I had for parts a 160 gig SATA HD so I instaled it. No problems Everything works great. The 160 I installed has an Op system on it (XP) partitioned in half. The original 80 that I just formated has (xp profesional) with no partition. Dont know why I did that? When I go to drive manager It shows that the 80 is the C drive and the 160 is the E and F of course. But what I was not exspecting was for the C and E drives to be listed together as the primary partition?? And for the F drive to be listed as the logical Drive ?? Does this make sense?? My other issue is in the future If I have any issues and need to reload windows I should have partioned the c drive. I dont know what would you all do. Should I scrap it all reformat and reload windows on the 1st 10 gigs of the 80 then my programs on the remaining 70? Format the 160 with no partion and save my documents? Or should I leave all alone? Or should I format the 160 with no partitionand leave the 80 alone? Not sure how this all works what should I do??
