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. 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.
If there are frequent network problems with the NAS device, and your NAS device can connect via USB or Firewire, then unplug it from the network and attach it directly to a computer via USB or Firewire. Open a command prompt and use the command
chkdsk X: /R
Replace X with the drive letter of your NAS device. This will scan your drive for errors and 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.
