FAT32 is an evolutionary improvement on FAT16 and FAT12 used in the early days of personal computing; NTFS is an entirely new approach to file management. FAT32 uses 32 bits per entry in the file allocation table (FAT), though only 28 bits are actually used. It is efficient for drives up to 16GB in size, as up to that level it uses 8Kb clusters. Above that size it switches to 16Kb clusters, at which point the file overhead becomes less efficient than NTFS. It also lacks all of the file security features available in NTFS.
NTFS is based on a database called the Master File Table (MFT) and includes file-level security options not previously available. Unlike FATxx, which writes the FAT in the first sector of the drive, NTFS keeps the MFT on the last sector and, IIRC, keeps a spare copy in the middle of the drive. NTFS is also crash resistant, as disk writes are logged, and if the system crashes incomplete writes are reconstructed from the log and rewritten. While it's still not recommended, shutting down a system with the power switch will rarely cause a data loss using NTFS. The newer system also adds file security capability, and automatic file encryption/decrytion as an option.
All in all, if you have logical drives bigger than 16 GB, NTFS is the recommended choice.

The USB driver in my PC used to work properly. But since I done some low level
operations the previously worked flash disk doesn't working anymore. And when I plug the flash disk in the port, I got prompt for "found new hardware wizard". Neither options in that dialog lead to success!

Try to test your flash drive with another computer with USB port. It is not working, then it mean your flash drive is broken and you need to have a new one. But if it detect as normal, you should check your system whether it is there is any problem with your system driver. Try to use the command sfc /scannow in the command prompt in order to check for any corrupt file system in your computer. Before you use the sfc command you should have windows CD in your hand because it might ask you to put in the CDROM in order to replace some corrupt that its found during the scan time.

Thanks Roath:
I almost forgot this thread, It reminds me things happened last year and people I knew. Actually I posted this message when I was in my "previous" job. It was just several months ago, but for me it seems happened in distant past. Thanks again!

Afther a long search over the internet and MSDN, I decided to ask someone more skilled than me that may be on this forum...
Is there possible to intercept an application file operation reqest? Let's say an application is triing to open a file, can I set a hook that notifies me that?
If not, how can this goal be accomplished? Writing kernel mode intermediate drivers for the i/o routines?
I hope I understand...because is a rough world out there...

Hi,
I have to write application to detect Disk configuration.
Is disk type is Basic or Dynamic?
I know Basic disk is supported by all windows versions, but dynamic is supported only by windows 2000, XP Pro, 2003 Server.
I am able to get the OS information but unable to get info for hard disk's.
Can anyone help me?
Thanks,
sanjay

Hello,
I have a huge problem here at home. I have accidently denied write access to my D: drive. No other account has enough priviliges to change the access on any of the drives. After I changed the settings, I found that it was the wrong group (Administrators). Soon I found out that I couldn't change priviliges anymore for myself or other users on the drive.
Is there a way to enable somebody to change priviliges on the drive when nobody has that privilige on that drive anymore?
Thanks in advance.

Well, in my experience the Adminstrator account can change permissions even when it itself doesn't have permissions to it. I'm thinking I did this once. Try logging in as the Administrator and changing it.

That didn't work unfortunatly. Maybe it would have worked when the access wasn't denied to the Administrator.
Now I have to options:
1) Back the entire partition up on an other partition, remove the D: drive and reinstall the entire partition.
2) Same as above, but use some tool to restore the NTFS system instead of backing it up.
Do you know if there is some (free) tool capable of restoring the entire file table of a partition?

you can connect your hard disk into another computer and access the whole drive content... see then where to remove the rights...

I don't think that I can change the access rights of one OS using another OS. The drive isn't a network share, and even if I change the rights from the network, or another OS, these changes don't apply to the local system.
I think that my best option is to backup the drive and re-create the entire partition.

hi bob,
i don't understand the point with the network.
i just suggested you to unplug the hard disk from the PC it is connected, and plug it into another...
you will see that by doing this, NTFS becomes nothing.... 
all the security rules that are seet on a system don't mean anything on an other... try it if you have another computer you can open and plug some material inside...

So you mean, that if I install the hard drive in another computer (different OS), the security settings are invalidated? Doesn't this mean that if I reinstall the hard drive does the same thing?
My only problem with this is that my OS is on the same drive. The drive has multiple partitions, but physically it is the same drive.
I'll try your suggestion when I have the time for it.

The problem with the network is that you can set local and network permissions. These settings don't affect eachother. So I think that you cannot set local security settings (local user) with a network administrator (remote user). I could be wrong though, since I'm not very into this subject.
Anyway, thanks for the suggestion.

ok for the local/network point ; actually, i wans't talking about that at all.
for your hard disk, yes, plugging it into an other computer - whatever OS, if it does understand NTFS - the rights are not effective for the new hosting system. there, you could remove the restriction you unfortunately set for the administrators, and try back booting on the system.
if it has worked, you won't have to reformat the partition.

I solved the problem now .
I used the method that required the least interaction from me, which was backing up the files, removing, restoring the partition and last restoring the backup. From me it only took 5 minutes and I accomplished this during dinner.
I'll try your method for experimenting purposes when I have more time on my hands. Thanks for the info!

Bob,
I think if you removed all permissions from a folder for even adminstrator, Windows would give a warning saying 'No one access'.
Under this circumstance, when you just doubleclick it would say 'Access is denied'. But you can go to Advanced, and try to take the ownership and then the control would be restored to the administrator.
Did this help you?

Hello,
Just even pointing to the drive made windows screem: "ACCESS DENIED". So even the property pages didn't show up.
I solved the problem by creating a backup administrator that had read access to the entire drive.
Second, I made a windows backup using the backup service.
Third I removed the partition, recreated the partition and restoring the backup. After that, everything worked again.

Not click on the drive. Just right click on it and choose property command and the dialog box appear. Go to the security tab and click on button advance. The new dialog box appear and go to the owner tab and take ownership of the drive. Then you will have full access to that drive.

Hi
I wanted to know how could I programatically add a path to the system in windows 2000,XP. In earlier DOS and win9x, I could use a PATH command in autoexec.bat file. I'm not sure if it should be the case for the latter windows. I also searched the registry for such entry, but I didn't get anything for that.
Thanks
