+\section Intro Introduction
+The Arduino SdFat Library is a minimal implementation of FAT16 and FAT32
+file systems on SD flash memory cards. Standard SD and high capacity
+SDHC cards are supported.
+
+The SdFat only supports short 8.3 names.
+
+The main classes in SdFat are Sd2Card, SdVolume, and SdFile.
+
+The Sd2Card class supports access to standard SD cards and SDHC cards. Most
+applications will only need to call the Sd2Card::init() member function.
+
+The SdVolume class supports FAT16 and FAT32 partitions. Most applications
+will only need to call the SdVolume::init() member function.
+
+The SdFile class provides file access functions such as open(), read(),
+remove(), write(), close() and sync(). This class supports access to the root
+directory and subdirectories.
+
+A number of example are provided in the SdFat/examples folder. These were
+developed to test SdFat and illustrate its use.
+
+SdFat was developed for high speed data recording. SdFat was used to implement
+an audio record/play class, WaveRP, for the Adafruit Wave Shield. This
+application uses special Sd2Card calls to write to contiguous files in raw mode.
+These functions reduce write latency so that audio can be recorded with the
+small amount of RAM in the Arduino.
+
+\section SDcard SD\SDHC Cards
+
+Arduinos access SD cards using the cards SPI protocol. PCs, Macs, and
+most consumer devices use the 4-bit parallel SD protocol. A card that
+functions well on A PC or Mac may not work well on the Arduino.
+
+Most cards have good SPI read performance but cards vary widely in SPI
+write performance. Write performance is limited by how efficiently the
+card manages internal erase/remapping operations. The Arduino cannot
+optimize writes to reduce erase operations because of its limit RAM.
+
+SanDisk cards generally have good write performance. They seem to have
+more internal RAM buffering than other cards and therefore can limit
+the number of flash erase operations that the Arduino forces due to its
+limited RAM.
+
+\section Hardware Hardware Configuration
+
+SdFat was developed using an
+<A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
+<A HREF = "http://www.ladyada.net/make/waveshield/"> Wave Shield</A>.
+
+The hardware interface to the SD card should not use a resistor based level
+shifter. SdFat sets the SPI bus frequency to 8 MHz which results in signal
+rise times that are too slow for the edge detectors in many newer SD card
+controllers when resistor voltage dividers are used.
+
+The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
+74HC4050N based circuit shown in the file SdLevel.png. The Adafruit Wave Shield
+uses a 74AHC125N. Gravitech sells SD and MicroSD Card Adapters based on the
+74LCX245.
+
+If you are using a resistor based level shifter and are having problems try
+setting the SPI bus frequency to 4 MHz. This can be done by using
+card.init(SPI_HALF_SPEED) to initialize the SD card.
+

+
+If you wish to report bugs or have comments, send email to fat16lib@sbcglobal.net.
+
+\section SdFatClass SdFat Usage
+
+SdFat uses a slightly restricted form of short names.
+Only printable ASCII characters are supported. No characters with code point
+values greater than 127 are allowed. Space is not allowed even though space
+was allowed in the API of early versions of DOS.
+
+Short names are limited to 8 characters followed by an optional period (.)
+and extension of up to 3 characters. The characters may be any combination
+of letters and digits. The following special characters are also allowed:
+
+$ % ' - _ @ ~ ` ! ( ) { } ^ # &
+
+Short names are always converted to upper case and their original case
+value is lost.
+
+\note
+ The Arduino Print class uses character
+at a time writes so it was necessary to use a \link SdFile::sync() sync() \endlink
+function to control when data is written to the SD card.
+
+\par
+An application which writes to a file using \link Print::print() print()\endlink,
+\link Print::println() println() \endlink
+or \link SdFile::write write() \endlink must call \link SdFile::sync() sync() \endlink
+at the appropriate time to force data and directory information to be written
+to the SD Card. Data and directory information are also written to the SD card
+when \link SdFile::close() close() \endlink is called.
+
+\par
+Applications must use care calling \link SdFile::sync() sync() \endlink
+since 2048 bytes of I/O is required to update file and
+directory information. This includes writing the current data block, reading
+the block that contains the directory entry for update, writing the directory
+block back and reading back the current data block.
+
+It is possible to open a file with two or more instances of SdFile. A file may
+be corrupted if data is written to the file by more than one instance of SdFile.
+
+\section HowTo How to format SD Cards as FAT Volumes
+
+You should use a freshly formatted SD card for best performance. FAT
+file systems become slower if many files have been created and deleted.
+This is because the directory entry for a deleted file is marked as deleted,
+but is not deleted. When a new file is created, these entries must be scanned
+before creating the file, a flaw in the FAT design. Also files can become
+fragmented which causes reads and writes to be slower.
+
+Microsoft operating systems support removable media formatted with a
+Master Boot Record, MBR, or formatted as a super floppy with a FAT Boot Sector
+in block zero.
+
+Microsoft operating systems expect MBR formatted removable media
+to have only one partition. The first partition should be used.
+
+Microsoft operating systems do not support partitioning SD flash cards.
+If you erase an SD card with a program like KillDisk, Most versions of
+Windows will format the card as a super floppy.
+
+The best way to restore an SD card's format is to use SDFormatter
+which can be downloaded from:
+
+http://www.sdcard.org/consumers/formatter/
+
+SDFormatter aligns flash erase boundaries with file
+system structures which reduces write latency and file system overhead.
+
+SDFormatter does not have an option for FAT type so it may format
+small cards as FAT12.
+
+After the MBR is restored by SDFormatter you may need to reformat small
+cards that have been formatted FAT12 to force the volume type to be FAT16.
+
+If you reformat the SD card with an OS utility, choose a cluster size that
+will result in:
+
+4084 < CountOfClusters && CountOfClusters < 65525
+
+The volume will then be FAT16.
+
+If you are formatting an SD card on OS X or Linux, be sure to use the first
+partition. Format this partition with a cluster count in above range.
