External hard drive and ExpressCache

I also use external HDDs all the time. I do a lot of photoshop work and keep photos on various external HDDs. Everything seems to function ok as far as working with the drives. Only thing is that the ExpressCache is constantly accessing the drives.

This causes 2 problems:

  1. Cannot eject a drive through Windows because it says the drive is in use. So if I want to unplug a drive and plug in another, the only safe thing is to shut the computer down. Not a deal breaker, but certainly inconvenient.

  2. Since the drives are constantly in use, I don’t know whether this will have any effect on the life of the drives.

I am using ExpressCache version 1.0.100.0 . I have tried to do research on this matter, and have not been able to find much.

Also, if I disable ExpressCache, everything turns back to normal with the external HDD.

And I guess I have the same question with the main HDD. With ExpressCache constantly accessing it does this have any effect on the life of the drive?

Would really like to hear from others on this subject. Thanks.
