Want recommendations for HDD monitor software

I have 2 internal and 3 external HDD's that I want to monitor. I have lost HDD's in the past and it has been a terrific PAIN! and while I know that monitoring software wont prevent this altogether, it could help.

I have tried a couple but for whatever reason the programs could not read the SMART data of my 2 internal drives.

Anybody have a recommendation for a good program?

Other than SMART software included with drives, I'm not aware of any real-time hard drive monitoring software, but there may be some.

For temperatures, I use HWInfo.

For general health, I rely on SMART, Intel SSD toolbox, and occasionally Checkdisk or the drive manufacturer's own utilities. I usually use HD Tune as a benchmark when I first install a drive.

Frankly, I'm not sure how useful the monitoring tools would be in detecting an impending failure.

However, I agree with ignatzatsonic in that I'm not entirely sure if you can ever positively detect an impending failure other than clicking noises from the drive, a reluctance for Windows to start or very slow performance.
