v1.0.0-beta.2 added several new timeouts that may help you if you have several attached external drives, or lots of network mounted volumes, or if any of your volumes are especially slow to spin up from sleep.
Open your system settings.toml and add the following lines:
commandTimeoutMs=60000
mountpointsTtlMs=60000
volumeMetadataTtlMs=1200000
This will set your command and mountpoint timeouts to a minute, and volume metadata to be cached for 20 minutes.
Here are descriptions for these settings:

# Settings for System.timeouts:

# +--------------------+
# | commandTimeoutMs |
# +--------------------+
#
# How long should PhotoStructure wait for a command that touches the
# filesystem (and doesn't do anything computationally expensive)? Note that
# external hard drives can take 10-15 seconds to spin up, so values less than
# that may result in timeouts.
#
# environment: "PS_COMMAND_TIMEOUT_MS"
#
commandTimeoutMs = 60000
# +--------------------+
# | mountpointsTtlMs |
# +--------------------+
#
# How frequently should PhotoStructure scan for new volumes (so PhotoStructure
# can detect when drives are inserted or ejected)? Shorter than 10-15 seconds
# may cause issues on Windows.
#
# environment: "PS_MOUNTPOINTS_TTL_MS"
#
mountpointsTtlMs = 60000
# +-----------------------+
# | volumeMetadataTtlMs |
# +-----------------------+
#
# How frequently should PhotoStructure reload volume metadata (like
# bytes-free, which is used in a health check?) Values less than a minute are
# probably not necessary.
#
# environment: "PS_VOLUME_METADATA_TTL_MS"

volumeMetadataTtlMs = 1200000
