Format or convert?

[Herzl Regev]

When converting a FAT filesystem into NTFS, what are the pros and cons of

using convert v. format, other than the backup issue? E.g. is there a danger

to the integrity of the files under conversion?

Converting FAT to NTFS is supposed to leave files on the partition intact.

As always, there might be some risk of data corruption or loss during the

conversion. It would be wise to have a backup of those files.



Formatting wipes everything out on the partition, so you most definitely

need to have files backed up to a different location.

Integrity of files is always a concern. Convert usually works well

and would normally keep the files intact Format would force you to

"copy" the files off the drive to be converted and then to copy them

back.

There is no need to format.



To convert to NTFS, you use the CONVERT command. But first read

http://www.aumha.org/a/ntfscvt.htm because there's an important issue

regarding cluster size that isn't obvious.



Also note that conversion is a big step, affecting everything on your

drive. When you take such a big step, no matter how unlikely, it is

always possible that something could go wrong. For that reason, it's

prudent to make sure you have a backup of anything you can't afford to

lose before beginning.

The main risk would be that of a power failure during the conversion. If

these is any possibility of this then it might be worthwhile to beg or borrow

a UPS. Otherwise, it's rare for the conversion to go wrong.
