    Error 0x8100001a - Backup/Restore (Win7)

    I had to do a new reinstall of Windows 10 and received this error when trying to restore from my external backup drive.

    Originally the backup drive was G, but after the reinstall, it became H. I changed it back to G in Disk Management, and applied the SDUTIL with no errors (Windows 7 Backup Recovery Error 0x8100001a - Microsoft Community).

    I still get this error message.

    Any ideas?

    Welcome to TenForums @lmmdf

    Backup and restore was always temperamental. For example, a corrupt mediaID.bin file on the backup drive can cause these sorts of problems. However, the backups are stored in .zip files. With a little effort your files can be recovered.

    In your linked thread a Microsoft poster referred the OP to a Microsoft support page that apparently no longer exists. Fortunately it has been archive in the Internet Archive's Wayback Machine. This may help you get your files back....

    This is not feasible. There are about 1500 zipped files for any one backup, and there is potential for something to be screwed up if not done properly. There must be a way for me to access my backed up files. This should be simple.
