USB drive unexpected container format error (Event 51)

[andry81]

I couldn't recall the error details, but the event log has having 2 errors for 2 drives almost at the same second:

An error detected on device \Device\Harddisk4\DR4 during a paging operation An error detected on device \Device\Harddisk5\DR5 during a paging operation

I've been formatting a container file on 2 USB drives at the same time being connected from the AGE STAR box into PC by a single USB cable.

After a container file formatting is started (~10-15 min) the error is appeared.

I think the OS thinks that the drives has not been busy for a while and turned them into sleep/hibernation/suspend/whatever because the option that could hide the writes on the drive from the OS Preserve modification timestamp of file containers, is enabled.

I have made a simple script to keep writes on each drive while it being formatted each 5 min and it made a trick. Seems no error now.

Expected behavior

Keep OS visible reads or writes to the USB drive while it being formatted?

Observed behavior

Disk access error.

Steps to reproduce

1. Connect USB Drive
2. Start for a container file format
3. Wait the drive access error
