A screenshot from Disk Management could shed some light on this. To open Disk Management press Win+R and type diskmgmt.msc – gronostaj – 2014-08-23T18:22:18.310

Actually, you have one hard disk, which is divided into six partitions, of which one is labelled C: and you are asking about another. Oh, how much confusion could have been saved had Microsoft gone with a scheme that clarified the relationship between physical devices and partitions, back in the early 1980s... – a CVn – 2014-08-23T18:33:23.163

Did the computer come with Windows 8 (and was later updated) or was Windows 8.1 a clean install? – and31415 – 2014-08-23T22:25:08.450

@and31415 It came with Windows 8 and was later updated to 8.1. – Chloe – 2014-09-01T20:57:57.267

Yeah, guessed that. Here's a related Microsoft forum thread which includes some explanation and possible solutions: Strange new Drive created by Windows 8.1 update
