1) Suppose I'm using the Windows VFAT file system, and a disk error
trashes the FAT entry I'm currently writing, and the block that contains
it.  How many files might I loose?




2) Assume that I'm using the Windows FAT32 file system.  A cluster is 1024
bytes long on this filesystem.  I have nothing cached except the partition
table.  How many disk accesses will I need to read a file named
"\config.sys" that is 10,000 bytes long?  What does each access read?
 Access #1: ____________________________________________
 Access #2: ____________________________________________
 Access #3: ____________________________________________
 Access #4: ____________________________________________
 Access #5: ____________________________________________
 Access #6: ____________________________________________
 Access #7: ____________________________________________
 Access #8: ____________________________________________
 Access #9: ____________________________________________

3) Answer question 2 for the ext2 file system.
 Access #1: ____________________________________________
 Access #2: ____________________________________________
 Access #3: ____________________________________________
 Access #4: ____________________________________________
 Access #5: ____________________________________________
 Access #6: ____________________________________________
 Access #7: ____________________________________________
 Access #8: ____________________________________________
 Access #9: ____________________________________________

4) Using long filenames on a Windows FAT32 box, how many directory entries 
would I need to store the file "12345678.1234"?



5) Using ext2, how can I tell if a inode entry is in use?  In other 
words, are inode entries zero'd when not in use, is there a reference 
count, what?  If there is more than one way, list them all.  If it's 
impossible, say that.





6) In Windows FAT32, a data block is corrupted.  How can I tell which file 
lost data?  In other words, given a data block, how can I find the 
associated file?





7) In EXT2, they keep many copies of the superblock just in case of data 
loss.  However, they only keep one entry for inode #2, the root directory 
inode.  How can they recover from the loss of this data?





8) List two advantages of the EXT2 file system, and two for the Windows 
VFAT file system.

EXT2 #1: ____________________________________________________
EXT2 #2: ____________________________________________________
VFAT #1: ____________________________________________________
VFAT #2: ____________________________________________________


9) If you had to right code for either file system, which would be easier?
    ____ EXT2    _____ VFAT32


10) Assume you're running VFAT24, a file system just like VFAT except it 
uses 24 bit points to describe disk locations.  You have a 30G hard drive 
to format.  What cluster size do you need?
