Windows 10: Secondary Hard Drive Disappears After Wake From Sleep

After the most recent update (1809), when waking from sleep Windows can't find my secondary drive. If I reboot it's back again, but having to do a reboot after sleep is NOT convenient! I was an earlier post that this problem occurred before (think it was 2016).


I have a Dell XPS 8930, I7, 12 gig ram, 16 gig Optane memory. I have a 240 gig SSD linked to the Optane using Intel's Rapid Storage Technology software.


Everything worked fine before 1809 and I've checked to be sure I have the latest version of the Intel RST software.


Help!

Secondary hard drive disappears after sleep on W10 anniversary update

Hi,

I have an annoying problem since updating my system with the W10 anniversary update. On my desktop, I have an SSD with the OS and apps and a couple of hard drives for data. ONE of my secondary hard drives
(a Toshiba P300) disappears after the system wakes from sleep. If I reboot the system it reappears in windows explorer. The other hard drive is always present.

There are a lot of mentions of a secondary drive disappearing like that on previous versions of Windows but I couldn't find anything on the net about the anniversary update causing it.

system is:

i5-3470

16gb ram

w10-pro 64bit

samsung 850evo

seagate 1tb

toshiba p300 3tb

 

Secondary Hard Drive Disappears After Wake From Sleep Since Anniversary Update

I'm reposting this issue because I marked the previous as answered but the problem returned.

Since updating my system with the W10 anniversary update (build 1607) I'm having this issue:

ONE of my secondary hard drives (a Toshiba P300) disappears after the system wakes from sleep, both from windows explorer and from device manager. If I reboot the system it reappears. The other 'data'
hard drive is always present. Even an external hard drive is always present.

It's happening on a desktop, I have an SSD with the OS and apps and a couple of hard drives for data.

There are a lot of mentions of a secondary drive disappearing like that on previous versions of Windows but I couldn't find anything on the net about the anniversary update causing it.

I've tried maximising (10000000 minutes) the value for turn hard disc after in the power options and the computer never goes to sleep if I don't make it. I don't have bitlocker enabled on any of the drives,

really hope someone can help

Secondary hard drive is waking up for no reason

Hi,

I formated my secondary hard drive, that means absolutely no data is currently being inside. The drive is excluded from Windows indexing and I programmed my drives to sleep after 1 minute for test purposes.

When the drive occasionnally wakes up, Process Monitor doesn't find any suspicious related process.
"QueryOpen" or "CloseFile" operations can be read but they do occur when I open a new Windows Explorer window and have usually no waking effect on the drive.
