Hi Guys, I had the following system built for me by OverClockers in 2016. At the time I thought that a 1TB hard drive would be enough, but it seems I was wrong! I'm going to fit a 3TB drive and have opted for the BarraCuda Internal Hard Drive (ST3000DM007) Unless there are recommendations for better drives within budget. (Under £80) Up until now I've only replaced various cards and fans, so fitting an extra drive is new territory for me. It looks pretty staightforward, but there are a couple of things I'd appreciate some advice on. I have two power connectors accessible, as shown in the following pic. The one on the left, circled in red, appears to be Molex, and the one circled in Blue is SATA. It looks like I'll have to undo the cable ties to access the SATA connection, as it's facing the wrong way, and is a bit inaccessible. That's not a problem, but just wondering on the best power cable to get? OverClockers have suggested this https://www.overclockers.co.uk/akasa-sata-power-splitter-ak-cbpw05-30-cb-058-ak.html However, it seems a built bulky, and I'm a bit cramped for space on that side of the case. As I only need one power connection, I'm thinking this might be more suitable - https://www.overclockers.co.uk/akas...ension-cable-30cm-ak-cbpw04-30-cb-057-ak.html I won't be fitting any additional drives in the future, but wanted to check there are no other advantages of using a splitter cable? I've also found this cable on eBay that seems like it would do the job, and looks like it might be even less bulky than the Akasa - https://www.ebay.co.uk/itm/30cm-12-...296831&hash=item2cd1421a47:g:p-sAAOSwYGFU035G My second enquiry is in sorting out the drive letters after installing the extra drive. Currently I have Drives C: D: and an external drive E:. I would like the new 3TB drive to become Drive D, my existing Drive D to become E, and the current Drive E to become F. Is it just a matter of reassigning the drive letters after the drive is recognised, using disk management? Running Windows 10. Hope someone can advise.
