HDD is C: drive NTFS system. Any suggestions please Regards Princy557 Additional Info: Reason I'm worried is that sfc /scanow returned nothing, but windows backup returned quite a few lines similar to the following.... Windows Backup skipped C:\Users\xxxxx\Documents because is it on corrupted drive C:\. Windows Backup skipped c:\Users\Public\videos because is it on corrupted drive C:\. Windows Backup skipped c:\Users\xxxxx\AppData\LocalLow because is it on corrupted drive C:\. and yes it is the way it wrote it.......' is it on..."
