I have three My Book Live Duos.
All of them do the following, and have always done the following (they are all on the latest firmware at the time of this post):
On the first Sunday of every month, starting at about 1:00 AM, the green light blinks showing activity. Access to the drive is extremely slow and limited during this activity. Writing even small amounts of data is pretty much impossible.
The activity finishes somewhere between 12-24 hours later (usually around 2:00 PM).
If I reboot the drive during the activty, the activity does not restart until the first Sunday of the next month. Data seems fine, and drive checks using the web interface return everything normal / no errors.
I would like to know,
WHAT EXACTLY ARE THE DRIVES DOING?
It is extremely annoying, and I would just reboot them to stop it, but since I have no idea what the drives are doing, I don’t know how “bad” rebooting the drives during this activity is.
Someone asked this question here, but got no useful response:
