Read Error or Metadata Corrupted - bad or just annoying?
True Image 2017 Mac V 3.3.8035
iMac iMac (27-inch, Mid 2011) running OS X Sierra v10.12.5
backing up to a nearly-new external hard drive
occasionally throws a "READ ERROR OR METADATA CONTENT IS CORRUPTED" message.
One time I ran Disk Utility First Aid, and retried the backup successfully.
This latest time that didn't work, so I used Disk Utility to unmount and remount the drive. Retry succeeded.
Can I safely write these off as just one of life's little annoyances? Or should I worry that I can't rely on my backups?
How is the external drive connected to the computer? If USB 3.0 and your drive does not have it own power source I would suspect that as the issue.
Most external drives connecting via USB 3.0 have power requirements that exceed that of a single cable connection. True Image will have issue with that.
It's USB 2.0, direct to computer as recommended by various sources.
Does not have its own power source.
You might try a different USB port if one is available. Many case mounted ports are under powered, it is therefore recommended that ports directly attached to the motherboard are used if possible.
