Preparing memory media
Memory media must be formatted before it is used. SATA SSD can be formatted either on the multi-role recorder
itself, on insertion of the media, or externally using the SSRFormat utility; CF cards can only be formatted on the
multi-role recorder. When the media is first inserted in a multi-role recorder, the file system is mounted. You can
format the media before or after it has been mounted.
N
OTE
: Only use approved memory media. For a list of approved CF cards, see the
CompactFlash cards
data
sheet; for approved SATA SSD, see the Solid State Drives data sheet.
The formatting process not only creates the FAT32 file system on the media but also pre-creates the PCAP
files to be used during recording. Media formatted using standard Windows® are not accepted by a multi-
role recorder until they are formatted by a multi-role recorder or the SSRFormat utility. Moreover, after any
modification to the file system of the media by adding or deleting files from a PC, the media must be refor -
matted before it can be re-used.
To prevent degradation of the logging rate, the SSRFormat utility must be used periodically on SATA SSD.
For information on using the SSRFormat utility, see “Formatting a SATA SSD using the SSRFormat utility”
on page 18 .
Formatting memory media using a multi-role recorder
1. Insert the media into the multi-role recorder.
2. Press and hold the EVENT button for three seconds.
3. When the displays shows Format? , keeping the EVENT button pressed, toggle the START/STOP switch to
the START position and back to the STOP position within ten seconds.
4. When the display shows Formatting xx% , release the EVENT button.
During formatting, the progress of the format process is displayed and the ERROR LED is on.
When complete, the display indicates a ready state, that is, N000 Stopped .
Do not disconnect power to the multi-role recorder until formatting has ended.
Formatting a SATA SSD using the SSRFormat utility
A SATA SSD can be formatted with a PC using the SSRFormat software utility. SSRFormat is a stand-alone
command line utility, which reformats the SATA SSD and reserves space on the drive for use by multi-role
recorders. The SATA SSD must be connected to a PC using a GTS/BAY/001 or an eSATAp cable.
SSRFormat is capable of identifying a disk previously formatted by a multi-role recorder. This prevents inadvertent
formatting of the wrong drive on the PC. If more than one such disk is identified, SSRFormat allows you to select a
disk. If the multi-role recorder formatting is lost, for example by formatting the disk from Windows, it may be
necessary to format it in a multi-role recorder before SSRFormat can be used again on that drive.
In interactive mode, SSRFormat always asks for confirmation to proceed before formatting begins. When not in
interactive mode (command line arguments include target volume name), SSRFormat destroys all data on the
target volume without offering a request to confirm.
When operating under Windows 7 (64-bit), SSRFormat must be run by an administrator user.
Using the TRIM command on legacy DRE/SSD/001
TRIM is an ATA (AT Attachment interface standard) command allowing an operating system to inform an SSD
which blocks of data are no longer considered in use and can be wiped internally. If TRIM is not used, over time
some sectors in the SATA SSD may become slow. At high data rates this can cause a multi-role recorder to drop
packets which it is trying to record. To avoid data loss, it is necessary to periodically format and TRIM the SATA
SSD with SSRFormat on a PC. TRIM must be used after the SATA SSD has first been formatted, and then at least
once every 25 formats. SSRFormat also has a command line option to reset the SATA SSD using the TRIM
command.
