Hi i've been having this problem since day 1 wih my WD My book (WDBACW0020HBK) wherein if its connected via USB3.0 cable into my USB2.0 PC port im experiencing the following problems.
PC randomly hang up during boot up. Im using windows 7 and it hangs during the bios detection, It does not even get into the part where windows shows it "Windows Starting" message.
I have two external drives, 1 is this WD and one seagate, randomly either one will not be detected, or the drive mapping changes which affects of my programs that autosave to my wd and seagate drives via the drive letters already stored in their configs.
To temporarily resolve #1 above, i have to reboot the PC a number of times.
For #2, i just reassign back again the drive letters.
I primarily used my WD drive for whole PC backup and currently to avoid the above issues, i just dont power up anymore unless the backup is scheduled to run for the day or my programs will need to write into them. Yes they dont occur if my WD is not powered up.
My WD Smartware version is 220.127.116.11
Any advise on how to resolve this permanently ?
