Time Machine

I have a mid 2011 MacBook air that I recently updated to High Sierra. I am having an issue with Time Machine backing up to an external drive. After approximately one gigabyte of back up it fails. I get a message stating an error occurred while copying files.
I have tried using disk utility to repair the disk and have also tried erasing and reformatting the external drive. Have done these several times with no luck.
The external drive is a Seagate goflex. It worked with no problems prior to the update. Any suggestions?

Have to test this with another drive.

In reply to: Time Machine

Seagate's do see a lot of failures but there are so many that this issue happens all the time. Drives take a dive just when you least expect it.

Did you try wiping the drive clean and starting fresh?

Drive wipe

Yes I have tried wiping the external and starting fresh but no luck. I'll have to try another drive as I don't really want to get another laptop just yet. Thank you for the assistance.

So it's back to the external

which may be the problem
try another cable from the MBA to the external.

Worth a try, and fairly cheap

Another cable

In reply to: So it's back to the external

I never even thought of that. Unfortunately a different cable didn't solve the issue. I'll have to procure another external and try that.

Overdue update

In reply to: Let us know how you get on with a new external

My apologies for the long delay. Life got in the way somewhat. Anyhow, I tried the external drive on an iMac running 10.9.5 and it backed up with no problems. Tried it again on the Air and same failure at approximately one gigabyte of back up. Seems like this indicates that it is related to the operating system. Is it time for a reinstall of the OS? If so, can the current data be retained while doing so or must it be a clean install?

Clean Install used to be an easy procedure
