Windows want to format my hard drive
New here, just upgraded from Vista Home Premium 32bit to Win 7 Home premium 32 bit. I went the upgrade option, not a clean install.
All went really well, cudos to MS. After the upgrade everything worked and all was good for a couple days. However this am I started the PC (desktop, home built) and when I clicked the icon for my D: (fixed hard drive) I got the message that if I wanted to use this drive Windows would need to format it first. All my data and images etc are on this drive, so was rather concerned. Anyway, I rebooted and the problem was gone and I had access to the D: again. I ran a chkdsk in this drive an no probelms were reported. Just concerned that it might happen again. Any ideas?
