ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / The RCC IRIG Chapter 10 standard requires that Chapter 10 recorders use the STANAG- 4575 (NATO Advanced Data Storage Interface) file system to store data files. The STANAG-4575 standard defines a linear file system in which each file is stored in a single contiguous block of disk space. There is a small directory listing at the beginning of the disk. This listing stores the starting position and length for each file. It also stores the file's name and its creation date and time. This file system is very efficient for storing files that are recorded sequentially because it does not require the disk to constantly update a file allocation table on each write. Unfortunately, the STANAG-4575 file system is not directly supported by Microsoft Windows. This means that it is not possible to simply attach a recorder's disk to a PC and copy the files directly using Windows Explorer. This paper will discuss an approach that allows the contents of a STANAG formatted disk to be read from a standard Windows PC. In addition to copying files from the disk, this approach allows several other useful operations to be performed on the disk. These operations include advanced copy options such as partial file copies and splitting files into multiple pieces. It can also provide a mechanism for deleting files, reformatting the disk and performing a sanitization procedure on a disk to declassify it.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / NATO NAFAG Air Group IV (AG IV) established the NATO Advanced Data Storage Technical Support Team (NADS TST) to investigate the technology and to develop an interface Standardization Agreement (STANAG) for recording, storage, and exchange of imagery data. Government agencies and industry involved in these technologies are participating in this effort.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / There are clear signs that data recorders using solid-state and disk-based technologies now represent a serious alternative to conventional linear and rotary tape recorders for a broad spectrum of data capture applications. As the number of RFQs specifying these so-called ‘new technology’ solutions increases, virtually every major manufacturer has responded with announcements of new off-the-shelf products. A NATO technical support team has even been tasked with drafting standards for certain aspects of solid-state and disk recorders. But what has caused this sudden explosion of interest? Strange to say, in almost every case it has been the perceived shortcomings of the new technologies which have forced the issue. For all their advantages, solid-state and disk recorders are essentially only temporary storage devices. To overcome this problem manufacturers have found it necessary to address the total data capture/storage/distribution/archiving scenario – with some interesting results. It is in the ‘data handling’ area therefore that some of the most significant advances are to be found. This Paper offers an overview of some of the new technology solutions now available - RAID (Redundant Arrays of Independent Disks), JBOD (Just a Bunch Of Disks) and FLASH memory recorders. New paradigms for airborne, mobile and laboratory data collection, handling, analysis and archiving are discussed, demonstrating that (for once) the migration path has been carefully thought through, with industry-standard data interfaces, true computer connectivity (Windows and UNIX) and familiar control techniques. It concludes that many users with a keen interest in replacing legacy products for whatever reason can now do so with confidence and minimal disruption to their day-to-day operation while nevertheless gaining access to the important benefits which ‘new technology’ solutions can offer.
