I have several tasks scheduled for full and incremental backups using TI 9.0, build 3677. The backups consist of all contents of my C: and D: drives to my E: drive. Occaionally I get an error that stops the backup until I respond to the Retry/Ignore/Abort dialog. However the error refers to trying to read a sector on another drive that is not supposed to be a part of ANY of my backups. TI 9 finds four disks on my PC: C, D, E, and K. They are defined as follows: Disk 1 is C: drive - Only Windows XP Pro and Program Files. Disk 2 is D: drive - All data and media files. Disk 3 is E: drive - E: is a drive that is dedicated to backups only. Disk 4 is K: drive - This is a USB Flash drive that contains a utility program that I use, and is almost always inserted. I have never backed up K: drive, nor do I intend to using TI 9. It is a relatively small USB Flash drive that is simple enough to just copy directly to a backup location. Nothing changes very often on that drive, so I do not need a regular image taken. When my scheduled backup generates the disk error, it stops my backup until I respond. Of course the backup tasks occur in the wee hours of the morning so I do not see them until I arise and sit at my PC later in the day. I don't want Acronis to even look at that drive - there is nothing good that can happen there! Yet the error messages in the log always says: "Failed to read data from the disk. Failed to read from the sector 127,408 of the hard disk 4: Retry/Ignore/ignore All/Cancel" Why is TI 9 even looking at this drive, let alone pausing my backup until I tell it what to do? My scheduled tasks all describe backing up Disks 1 and 2 to Disk 3 - Disk 4 has never been selected in any backup task. Any help for this? Thank you.
