I use 3 My Book External 3TB drives in a WIN 8 Storage Space and use it for storing videos. After setting up the Storage Space, I noticed that playback on videos invariably hung up after a while, and finally attributed it to the default Sleep Timer setting, which is just 10 minutes. Theoretically, both the WD SmartWare program and the WD Drive Utilites allow you to access and change the Sleep Timer.
However, both of those programs fail to work at all, if the drive has been part of a Storage Space.
I have found nothing that can access the Sleep Timer settings if the drive is in a Storage Space.
Either SmartWare or the Drive Uttilities program, or both, need to be updated to allow access to these drives while in Storage Places.
Is anyone out there, besides myself, using these drives in Storage Spaces? Anyone have any ideas about accessing the Sleep Timer Settings? (I have already tried attaching a drive to a WIN 7 computer, but without reformatting the entire drive, and losing all the data on it, it still will not allow access to the Sleep Timer settings.)
