0x8007045D Error Fix

The 0x8007045D error occurs in Windows Vista & Windows 7 when you try and backup to an External HD (Hard Drive). The error itself has been caused by Windows’ inability to correctly connect to an external media device. Although many people report the problem occurring when they try and burn files to their CD / DVD drive – it is a common problem if you’re attempting to backup to an external hard drive as well.

This error will typically show in this format:

  • I/O Device Error 0x8007045D

The 0x8007045D error is caused by your computer being unable to connect to the external device on your PC.

  • Run Checkdsk
  • Disable Security Applications
  • Shrink Disk Volume
