The venerable fat16 and fat32 file systems are still in widespread use today. Devices such as digital cameras, satellite navigation systems, memory sticks and mp3 players all make use of FAT
Mount a FAT file system in Linux, and it will appear as something like this:
[root@pluto ~]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb 7716112 7274796 441316 95% /media/0EB5-6037
/dev/sdc1 15549952 14225152 1324800 92% /media/1FC3-3137
Those hex numbers on the left are the default volume labels, and pretty unfriendly they are. The two entries above actually correspond to an MP3 player (Sansa Clip+) and the player’s expansion SD card. I used mlable to allocate more meaningful volume names. Continue reading
Flash drives (as in memory sticks) are a popular choice for backups. A 64 Gb drive can be bought for just over £20 at the time of writing. Once your data is backed up to the drive, it is easy to store in a safe place or transport off site for added protection. Actually that applies to any portable hard drive, as does the following procedure.
Most flash drives come formatted as FAT32. That is fine from day-to-day but there is a strict 4 GB limit applying to the size of any file. Backup software is likely to produce large archive files well over 4 GB, so won’t work well with FAT32. What’s needed therefore, is a better file system. Continue reading
The venerable fat16 and fat32 file systems are still in widespread use today. Devices such as digital cameras, satellite navigation systems, memory sticks and mp3 players all make use of FAT.
The files in a FAT file system are arranged in a strict order. This can affect the way that some devices behave. For example, some MP3 players will play songs only in the order in which they are arranged on the device, rather than the more convenient alphabetical or alphanumeric order. Music players that use USB memory sticks and in-car USB systems can be affected in the same way. The only way to get the songs to play in a more sensible order is to sort the directory (folder) in which they are located. Continue reading
