Hard drive space unallocated after pc reset

[Guest Daire Bunting]

Hello,So around a year ago I had an issue where my windows files corrupted and I had to completely wipe and reinstall windows.however when I done so it said that all the storage I had used until that point was inaccessible and too this day just says it is unallocated and I am unable to extend any partitions or create new ones there this has created an almost 1.5TB gap in my drives which has not only cost me a large chunk of storage capacity but also slowed my drives down a bit.(this is on both a hard drive and an ssd)Any advice or tips would be greatly appreciated Thanks
