How to make File History retain drive IDs
Like many users of Microsoft’s latest OS, Don Williams is getting his sea legs with Win8′s File History.
- “I understand about assigning an external drive to File History. But what happens if you connect a different external drive — not the drive originally used for File History backups?
“How can I ensure that File History won’t write files to the wrong drive?
“If I turn File History off and then back on again, will it start all over again from scratch, or will it pick up where it left off?”
Windows should — I repeat: should — be able to keep track of different external drives.
Windows typically assigns each drive a coded Device Unique Identifier (DUID). The identifier is generated the first time you attach a drive to a Windows PC, and it’s completely separate from whatever drive letter you might assign to the drive.
