i ahve wd 20ezrx model and WD told that 64 MB of cache is for thsi drive but when i checked by hdtunepro it says buffer /cache n/a what that means ?
Is this drive faulty ?
As I said earlier it happens, and I saw it numerous times on others as well as mine too. And I don't know why. It could be censors not reading by the software properly. But if the status is showing good then nothing to worry about.
