Okay, so I can't ever remember having this problem before... but now it's an issue.
Simply put, I wanted to take advantage of the free upgrade to Windows 10, since it handles Retina displays much better than 7. But before that, I want to back up my files. So, I attempt to run backup, but as soon as I click start... I get the "Error code 0x80070005. Access is denied."
Tried a number of solutions I found on Google and Microsoft's website, including checking system services, turning off Avira temporarily, taking ownership of the external hard drive, running backup as administrator, and extending the drive partition to include some unallocated space at the top of the disk, but none of this worked. I still got the error.
Next, I tried AOMEI's free backup software, but it could not detect my operating system drive! In fact, it said I have 46GB of unallocated space in the middle of my Windows partition, which is weird because that doesn't show up in any other software... it can't even detect that any partition is NTFS. Granted, the partition setup on my internal drive is a (functioning) mess, but that really is strange...
At any rate, I'm trying to backup my files to a Toshiba Canvio External, which has 700+ GB free space and is formatted NTFS. I need help ASAP as the free upgrade is no longer available after July 29th...help!!
