Title: Re: Question about FAT (repost)

【 In Jungle (Free Thorns)'s post it was mentioned: 】
: I think it should be FAT16. I asked the person who originally made the disk.
: And if it were FAT32, then wouldn't my calculation be off by even more? (4k = 8 sectors/cluster)
: These 32 sectors/cluster are really too strange. A 1.2G disk should be 64 sectors/cluster.
: But using FAT32 to explain it doesn't seem quite right either.
: Of course the original system may have been Win97. Would it do anything bad?
: Also: the root directory position in my original post was wrong. What I calculated later was a directory in another place,
: and this directory is correct, because I traced along and found several directories, including the document directory that should be recovered most.
: These are the directories from which I was able to summarize the pattern.
: What's the difference between relative sectors and physical sectors? Surely their size wouldn't be different too...
A 1.2G disk should be 32 sectors/cluster. Calculate it:
1.2*1024*1024*1024/65536 = 19660.8
The relative sector I mean starts with the first sector after the root directory as sector 0. Physical sectors are expressed by cylinder,
head, and sector.
I think manual recovery is too complicated. Better to find some recovery tools (you may need to hook it up to another hard disk),
such as RecoverNT, RecoverAll, Lost&Found. Virus and articles before the Win95 edition had very detailed introductions,
so the recovered contents can be written to another disk without changing the original disk.
If you do manual modification, it's also best not to directly modify the FAT. Just manually write the found files to another disk
(using DiskEdit).

Game Buster, Game Tool, Game Wizard, FPE, Game Knife, Game Key,
Game Worm, Game Master...
Which one should I use? (!@$%*)
I'm thinking, thinking and thinking... zzz
