Wdc wd10jpvx-22jc3t0

have a hard drive WDC WD10JPVX-22JC3T0
off each time when idle.
but the code starts, starts runs that require more time.
The system windows 7 disk is not worth saving
How to fix it?

There is an utility on WD’s site for changing these values. However, I do not believe it is compatible with this particular hard drive model. Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
