I have an external Seagate 400 Gb drive I use for Backups, using the Vista Ultimate Backup. Have made total backup and then daily backups of files that have altered. All of a sudden the backups are failing despite there being 200 Gb free. It fails at unable to create shadow copy insufficient sapce.
Can't see a logical explanation other than wiping the drive and starting again, but from the look of Google, others have this problem, but I didn't see a solution
