Solution for WD Hard Disk Drives

I use program WDIdle3 under DOS and turn off parking heads.

https://support.wdc.com/downloads.aspx?p=113

Enter BIOS and change Mode from AHCI on controller on IDE or Compatible

And one more and IMPORTAND!!!

For the duration of the program WDIdle3.
Connected to controller only disks for change idle time.
Because utility WDIdle3 changing all HDD which conneted on controller.

Using
wdidle3 /r - current configuration ilde time on disk

wdidle3 /d - turn off idle time (I use this option)

wdidle3 /s50 - set time 50 secons (you can use 20, 30, 40 or above, read manual
please)

wdidle3 /? - help for program

- - -

Turn off idle timer.
Work fine.
Speed when use rsync
320 - 340 Megabytes per second.
No error in system log.


P.S.
HGST and WD the same brend and one technology and i thinks work this solution
too.
