    I just wanted to know that, recently i just converted my main c:\ from FAT32 to NTFS just because it couldn't hold files more than 4 gb, only NTFS system can store file more than 4 gb. Now, my question is that will this conversion affect my computers performance, gaming, etc.
    Replies would really be appreciated !!
    Thanks :-D

    AFAIK, the NTFS file system is much more robust than the older FAT32 system. It is a format that was first used with Windows NT AFAIK and has proved itself enough to be the default file system for all the OS's since and including Windows NT and Windows 2000. Not slower at all. It also provides better security I think. Overall, just better.

    NTFS 'rests' the hard drive 'head' in the middle of the disk where it puts all the directory. THis means that the head never has to seek more than 1/2 a disk to find it's target. FAT32 stores all the info at the outer edge of the disk and sequentially works in towards the mddle. Data is 'safer' at the outer edge as the head disk speed is greater at the larger diameter and the head 'flies' higher thus bits of info stored are 'bigger' and therefore more accurately decoded by the electronics and also any 'dust' or debris has to be bigger to cause a head crash. NTFS ignores this (since modern drives are less prone to hard crashes. NTFS also store any files you delete in the unused portion of the disk (no matter how you try to delete them) so the police, fbi and anyone else who knows the secrets of Windows can see what sites you have been looking at after your partner has retired for the evening....

    Note the term crash used above meana an unintentional physical interaction between moving and stationary parts of your hard drive and not a computer crash in the general sense of the term (ie windows screwing up your diary).

    back all your files up and re-format, but I'd suggest you stick with NTFS like wot I do!

    as far as I know NTFS is best!!! All my drives are formatted to run on NTFS. And my computer runs smoooooooooooooooooth, inspite of all my junk on it!!

    I don't think there will be any serious problems with NTFS. Maybe problems will even reduce in number when you shift from FAT to NTFS.

    I don't have much knowledge about these file systems. Any more replies would help me too!!

    It doesn't matter if you only use Windows, but a Mac cannot write to NTFS, whereas FAT32 can be written to.

    Also, wert, you said NTFS stores all your deleted files in another part of the disk? What if you fill up your hard drive? Where does it put them then?

    It simply overwrites all the available empty space first then overwrites the 'hidden' stuff last of all.

    I might be wrong, but I'm pretty sure FAT32 also just changes the file allocation table to flag an area as empty when you tell it to delete a file, leaving the actual data still there until it has to overwrite it with new data. This greatly increases the life of the drive, since it basically cuts the amount of writing it has to do in half (otherwise you would have to basically write every file twice, once to create it and once to obliterate it).

    I don't see the point of what all the criminals do on TV shows and films when they set their hard drive to "ERASE ALL DATA" and a huge progress bar pops up when all they really need to do is unscrew the hard drive casing and let the disk scratch itself. Or maybe just place a rare earth magnet next to it. All computer hackers should have a rare earth magnet kept somewhere as standard.

    Scifor you are correct that the area is marked free (in FAT & FAT16/32) but still has the data, however writing to a disk is completely non-destructive, the head flies above the disk by a few microns. THe head is electrically energised to produce a magnetic field which magnetises a small area of the disk, the next time the head passes over this, a small current is induced in the head. Most hard disk errors are caused by contamination where the head collides with some particle and damages the disk surface.

    Your rare earth magnet may not work, scratching the disk may not work. Next time you want to re-format a disk try the following.

    Whilst working in Dik drive Development at IBM in the late 80's we were approached by the fraud squad (British Police) and asked if could recover data from a PC which had been thrown out of 2nd story window, and thrown into a fire.
    we recoverd almost all the data. On another occasion a drive which had been hit with a builders hammer and had deformed disks also had the data recovered.


    Manually delete all files and data from the disk (ie highlight delete) then look at the disk properties, it will correctly report the total disk size, but the free space will be less than this. Next reformat and then again check total vs free space they will now agree. Another thing you can try is to abort the format some way into it and you will see that ALL of the data remains.

    Hollywood is somwhat removed from reality and not a reliable source of scientific information.

    If you really want to kill a disk either scrape the coatings off both sides of all the disks OR re-format the disk then copy a file to the disk that is exactly equal to the size of free space.

    There are programs that supposedly delete everything (which is possible) but I do not have or use such programs.

    I can pretty much guarantee that the rare earth magnet thing will not work, unless you take the drive out of the computer, open it up, and rub it all over the platter - which will probably take longer than just writing over everything. Also, like wert said, physically scratching the disk isn't a good way to do it - determined people will probably still be able to get data off the platter. Simply doing a "software erase" where you wipe the drive with random data is the best way to erase data for good - and you will still be able to use the drive afterward. You could probably also eliminated data by heating the platter until it was above the magnetic blocking temperature, but again, that would probably take longer than simply doing a software wipe.

    All the stories that you hear about people physically destroying drives are silly. Physical destruction is completely unnecessary, and simply wastes a good hard drive that could have been reused.

    When you get a hard drive today it comes with a low level format on it already. Years ago we used to have to low level format them ourselves. There was no drive when you first turned on the hard drive.

    You had to enter the number of heads, that also told it the number of disks. The number of sectors and the number of tracks.

    Sometimes you had to tell it the interleave. Some programs let you play around with the interleave. You could change how the sectors were read per revolution. You read one skip one, or something to that effect.

    But the program used to do a write and read, on and off, of every bit of the hard drive. I am sure you could wipe a hard drive like that. It took a while and always found a bad area on every drive I ever tested.

    The NYB virus was pretty slick. I do not know how it worked exactly. I actually had a computer infected by the virus. I just took it to the place where I got the computer, it was under warranty and they used a debugger utility, to change one value in the processors register. They just directly accessed the register and entered the value in one of the registers.

    Sounded pretty scary to me. But instantly the computer was ok. The funny thing about the NYB was that, it effected the computer but did not down the computer.

    Sincerely,


    William McCormick

    You can easily convert FAT32 to NTFS. From my experiences,you should use NTFS if you are using only one system. This is because it is more secure than FAT32 but FAT32 can handle more than 4GB. My old hard disk can be formatted by FAT32 and its capacity is 40GB. If you are using dual boot such as windows and Linux, you should format with FAT32 if your storage support because Linux operating system can view FAT32 only. This is not necessary but when you have some viruses in your windows, you can evenly delete them or copy data files if needed. Some talk that FAT32 is more stable than NTFS Formats.
