7 External Storage
HDX-SSD is not only able to replay material ripped and stored on network attached
storage but can also replay material stored on other relatively small capacity devices
temporarily connected via one of its USB interface sockets.
7.1 USB Storage Devices
A locally connected storage device will most likely be
a memory stick connected to one of the HDX-SSD’s USB
sockets.
Note: The amount of music stored on an external device
determines how long the HDX-SSD will spend scanning
the device when it is first connected before the music is
available to browse.
Note: Locally connected devices are re-scanned every
time the HDX-SSD starts up.
The tracks found by the HDX-SSD on locally connected
storage will only be held in its database while the storage is
connected and switched on.
Note: Local connection is only intended for relatively small
music collections on temporarily connected memory sticks.
Any large capacity storage should always be connected
via a network.
In order for USB stored music to be available to the HDX-
SSD, for playback various conditions must be met:
• Music files must be in AAC, FLAC, MP3, or WAV
formats (up to 24 bit, 192kHz).
• Music files must be unprotected by DRM encoding
that restricts them to specific playback hardware.
7.2 Network Shares
Before material stored on shared network devices can
be accessed by the HDX-SSD, it must scan the network
to identify the address of each share and to build a
database of the locations and details of the available
audio files.
The HDX-SSD automatically scans the network when first
switched on and will then periodically scan to find new
network shares and identify any changes to the available
audio files. It may however take a considerable time
following connection of the HDX-SSD to the network for
changes to be reflected in the HDX-SSD’s database.
Note: Network scanning is carried out at up to several
hundred files per minute although this figure depends on
the speed of the file storage device.
The music files found by the HDX-SSD on network shares will
be incorporated into its database and remembered until
any changes are identified, irrespective of the HDX-SSD
being switched off.
In order for network shared music files to be available
to the HDX-SSD, for network or local playback various
conditions must be met:
• Folders containing audio files must be set up to
be “shared”. Refer to the folder’s host computer
operating system user manual for details on setting
up shared folders.
• Music files must be in AAC, FLAC, MP3, WAV, Apple
Lossless, Ogg, AIFF or WMA formats (up to 24 bit,
192kHz).
• Music files must be unprotected by DRM encoding
that restricts them to specific playback hardware.
Network shares can be viewed and managed from the
Front Panel interface Network Shares menu. See Section
4.8.3
7.3 Music Stores
Any Network Share can be converted to operate as a
HDX-SSD Music Store – a location where the data from
ripped CDs is stored. At least one Network Share must be
given Music Store status when the HDX-SSD is first installed.
Promoting further network shares to Music Store status may
be appropriate if the first used Network Share is becoming
full, or if rip storage distributed across multiple network
shares provides enhanced network convenience or data
security.
Note: Enhanced data security is only likely if the network
share is a RAID device.
Note: When a Network Share is converted to Music Store
status it will no longer appear in HDX-SSD’s Network Shares
list.
Music Stores are used as rip locations by the HDX-SSD in
order of priority. CDs will be ripped automatically to the
highest priority Music Store until it is full, when the next
priority Music Store will be used.
Network Shares can be converted to Music Store status
via the
Add New Store option of the Music Stores Menu .
See the following section and Section 4.8.4 for more
information on Music Stores.
Important: Files should never be added to or deleted from
Music Stores via an alternative computer operating system.
Note: This is because Music Stores contain not only the
ripped CD data files but also the associated database
and meta-data files. External manipulation of a Music
Store will almost certainly result in database or meta-data
corruption.
