That is a funny statement :-)
A correct one however. I should have said no visible bad sectors. Every
drive has lots of bad sectors but the drive itself keeps these isolated and
out of the way and invisible.

What if the drive gets _too_ many bad sectors?
Is it goint to crash? |

Retire the drive.

More bad sectors than the drive can handle internally could be used as a
definition of a drive crashing. |

But FAT can handle bad sectors, couldn't it?
When does OS mark the bad sectors?
I think it may do it in two situations:
1. FORMAT time
2. Normal data access time
Am I right? |

Not without first being involved in a file going bad.

Usually during the initial format and later if a file becomes unreadable.

For FAT16 and FAT32 on MS's platform, is the statement above still true? |

The second part of the statement is valid for NTFS only.

Nope, True for FAT and W98 and older MS FAT OSs. I assume it's also true
for FAT in NT4, W2K and WinXP although bad secors outside the drive are so
rare that I can't say I seen one in the more recent MS OS-s. Can you
provide any references for your claim? |

XP
No block remaps in FAT
With FAT, it is hard, since it is hard to find the previous block number -
the FAT list is single-linked.
