Windows 8 Backup has been working fine for 12 months to an external Seagate USB hard drive.I'm now getting a "device not ready" message with error code 0x80070015 and the backup fails within 30 secs of starting. I've checked the drive for errors and there are no problems. I can read /write files to the external drive. There is ample spare space on the external drive to store the backup file.Please advise how to investigate and solve this problem.

Filling out System Specs would save asking all about the external drive model, your system HD etc..

Some externals spin down to save energy. Some can be set to spin up and stay up. I don't know what you have for HW.

btw I wrote a small hack that creates or deletes a file every 5 minutes to keep drives from spinning down. DriveAlive may be downloaded from: Miles Ahead Software

If it's an energy saver external you could try that as work-around.

I've since discovered the Windows 8 Pro (64) backup fails to any hard disc but a system image can be backed up. Backup showed the error ‘disc not ready’ 0x80070015. The Event Log showed Event ID 4100 – Backup did not complete successfully because a shadow copy could not be created. Free up disk space on the drive that you are backing up by deleting unnecessary files and then try again.

Backup is now working fine after doing the following - I'm not sure which did the trick.

  • sfc /scannow – found 4 errors and fixed them
  • Changed Windows Backup Service from Manual to Automatic
  • Changed Volume Shadow Copy Service from Automatic Delayed Start to Automatic
  • Defragmented all hard drives and ran chkdsk /f (but no errors found)
