A small number of files have been added to the root directory in a newly created example FAT32 file system. The used entries in the FAT are shown in Table 3. Table 3: Example FAT32 entries Entry Number 0x00000000 0x0ffffff8 0x00000001 0xffffffff ?? (Nor 0x0b000002 0xOfffffff 0x00000003 0x0fffffff 0x00000004 0xOfffffff 0x00000005 0x00000006 0x00000006 0x00000007 0x00000007 0x0fffffff 0x00000008 0x00000009 0x00000009 0x0000000a 0x0000000a 0x0000000b 0x0000000b 0x0000000c 0x0000000c 0xOfffffff 0x0000000d- 0x0000000e 0x0000000e?0x0fffffff ?… . d) The cluster chain for the root directory starts at 0x00000902 in the FAT shown in Table 3. Other than the root directory, how many other files are in the FAT?Explanation / Answer
ANSWER:
0FFFFFF8-0FFFFFFF mark the end of file.
As mentioned, the first 2 entries are reserved and the root directory starts at 0x00000002. The value in 'entry' column represents the 'number' value of the next cluster in the chain or marks the ned of the cluster. So to start,
File#1 : 0x00000002 (Marked by end of cluster 0x0fffffff)
File#2 : 0x00000003 (Marked by end of cluster 0x0fffffff)
File#3 : 0x00000004 (Marked by end of cluster 0x0fffffff)
File#4 : 0x00000005 ->0x00000006 ->0x00000007 (Marked by EOC 0x0fffffff)
File#5 : 0x00000008 ->0x00000009->0x0000000a->0x0000000b->0x0000000c (Marked by EOC 0x0fffffff)
File#6 : 0x0000000d ->0x0000000e (Marked by EOC 0x0fffffff)
