Network Attached Storage (NAS) devices
Many NAS devices are sold with old firmware, i.e. they contain bugs that have been fixed since they were manufactured/shipped. These bugs can often cause problems with SyncBack, e.g. problems replacing files, and more seriously can give the impression that a backup of a file has been made when it has not. It is strongly recommended that after purchasing and installing a NAS device you do the following before using it:
- Check the manufacturers site to see if newer firmware is available. It is important that you use the correct firmware for your NAS model. If a new version is available then upgrade the firmware. Check the instructions given by the manufacturer on how to do this.
- After upgrading the firmware you should have your NAS device scan the disk(s) for any errors.
chkdsk X: /RReplace X with the drive letter Windows assigned to your NAS device. This will scan your drive for errors and hopefully fix them. Sometimes the built-in NAS device software (usually accessed via a browser) does not properly scan for, and fix, errors on the drive.
