Does deleting a volume on a hard drive through Disk Management in Windows 7 delete all information that is on there? Here's my story.....friend of mine has an HP Pavilion desktop PC, and the motherboard goes bad. He replaces it with one that fits the case, but it's not the exact same motherboard that was in there......so once the motherboard is installed, his hard drive doesn't boot into Windows....it keeps coming up to the recovery thing.....and of course, the recovery thing doesn't work because it's looking for the other motherboard. So I tell him to go out and buy another hard drive so we can make that one the new boot drive, then we can hook up his old one afterwards and move all of his pictures off of the old one. We do exactly that, new install of Windows 7 works great, so we hook up the other drive and it shows the D: drive as HP_RECOVERY volume, and that's it....Windows only sees the Recovery section of the old hard drive. When I right-click on My Computer in Windows Explorer and then click "Manage", then "Disk Management", it sees the portion with his old data on it, but it doesn't have a drive letter, and it doesn't allow me to assign a letter to it.....the only option I have is do "delete volume".....so.....does deleting a volume remove everything on that drive?
