Solved Question about the danger of TLER on a home desktop

Hi everyone!
Wanted to ask, I’ve had an enterprise WD hard drive in my home computer for years now and no problems. It is my only hard drive in the system. I just read about TLER possibly being an issue for an enterprise being used as a home desktop. Can anyone please explain to me whether TLER for home use is not a big deal or is an issue. I am aware that it wouldn’t do error recovery as long as a consumer hard drive in this case but just want to make sure it won’t fail the entire drive due to one problem. Just want to make sure I’m safe in case this happens. Thanks!!

So I did a bit of Googleing and someone mentioned that a WD rep said the TLER can be toggled on and off in the SMART settings.

Maybe you can try emailing WD and see if this is true.

It's not going to fail the entire drive unless the controller board goes out and TLER wouldn't help in that situation anyway.

If you are going to use this on a home system, I would recommend setting up 2 partitions, one for the operating system, one for data. That way if an error occurs in the OS partition, you can reload the OS without losing your data.

I'm still not sure why you don't want to use an SSD drive. It would be much faster. If you're worried about data loss then back up your data on an external drive or cloud storage which you should be doing anyway. Even Enterprise drives will fail at some point.

It's not a huge issue. If your hard drive is having enough trouble reading a sector that TLER is a factor, it's on its way out regardless and needs to be replaced immediately. It just means any data recovery attempt afterwards is that much less likely to work. (Always backup regardless of drive type or configuration, etc, etc.)
