Is there a way to convert NTFS partitions to some Linux Filesystem in place without copying data?

Q. I'd like to convert a NTFS partition to a Linux File system in place without copying the data.

A. I don't think you can convert it directly without backing up your files first on a separate media unless you don't need the files.

GParted can do the conversion from NTFS to a Linux File System.

How to reconize linux file systems on windows?
Q. I have both linux and windows working perfectly, but i'm not able to use the partition created for linux in windows. Linux has no problems in recognizing windows file systems. So please find me a way.

A. generally windows doesn't support linux file system( ext2,ext3 ), but you may be able access using some software like "ext2fs". you can download it from the given link "http://www.fs-driver.org/download.html"

How do you determine what Linux file system your using?
Q. When you log onto a Linux system and get to the command prompt, how can you determine which of the many file systems supported in Linux you are using? Is there a command that will identify it?

A. Use fsck with the N option which just show what would have been done, but also show you what type of filesystem it is.

fsck -N /dev/(device-name)

e.g.

fsck -N /dev/hdc2

The 'mount' command wont help if the filesystem isn't mounted, and looking in /etc/fstab wont help because you cant be sure that information can be trusted.

Linux - File system structure between different distros?

Q. I have been reading about Linux distros and I am lost in that kind of "flavors".
Would someone help me understand the main differences in the file system structure in Fedora and how this is compared with the file system structure in Debian?

A. From an end-user perspective there really isn't much difference. Mostly the file system structure (do you mean layout?) is the same. For example, standard programs live in one or more of /bin, /sbin, /usr/bin, /usr/sbin, and custom applications live in /usr/local/bin (but you don't need to worry about any of that, as the PATH variable manages finding them).

Debian-derived distributions provide for some configuration within the directory /etc/default/, and network interfaces are either configured in the file /etc/network/interfaces or by Network Manager.

RedHat-derived distributions (including Fedora) mostly use /etc/sysconfig/ for configuration files, and network interfaces are configured in separate files (one per interfaces) underneath /etc/sysconfig/interfaces/ or by Network Manager

Unless you're getting into writing portable installation scripts that's about as far as you really need to go.

How to Install Red Hat Linux Desktop version 4?
Q. I want to install Red Hat Linux Desktop version 4. Please tell me the step-by-step installation and which file system will be best for this O/S?
Like in windows, we have NTFS file system(which has very security features).
Is there any such file system in Linux?
Which file system should i use?

A. Put the CD in the drive, restart the computer and follow the directions. Take the defaults - they're the best choices for a beginner.

Do I need to defrag a big linux hard drive?
Q. I have a big hard drive (300GIGs) and wonder if I can do something to get better performance out of it. I run Ubuntu Linux. Is there something like de-fragmenting or optimizing the hard drive for linux? The file system is ext3.

A. If you are looking for extra speed I suggest backing up your data and upgrading to Ubuntu 9.04 which supports ext4.

Partitioning a hard drive with two different Linux OS's sharing a common file system?
Q. How do I partition my hard drive with two Linux operating systems so that they have a common shared file system? It was explained to me a long time ago but I forgot. THANK YOU in advance for your time and consideration.

A. First, contrary to what jerry said, two /home/ directories may not be safely shared. There are two many config files, you you may end up with name and version conflicts.

/temp may be safely shared

the swap may be safely shared (but wierd thing can happen on resume from hibernate)

also /boot/ may be safely shared so long as you only configure from one system or the other, and there are no filename collisions (unlikely so no really safe in practice)

To just share media file, I would just create a partition and mount it at /share by editing the fstab of both systems. Then you can make your /home/user/Music a soft link that point to /share/Music. Repeat for Documents, Pictures, Downloads, and whatever else you care to share.

What is the best file system to use on an SSD?
Q. We want to install a Linux system on a SSD and were wondering whether there is a preferable file system choice.
Since the drive does wear leveling, I guess the FS doesn't matter *that* much, but still, fewer write accesses are better. Do some FS manage to get fewer total bytes written per pay load bytes?

A. Check out SSD Linux.

Is there any way to format a hard drive with Linux file system under windows?

Q. I need to be able to format my drive with linux file system in order for it to work in the western digital NAS enclosure. Thanks.

A. Steven's right, but you'll need some extra software to put files on or even view the partition from Windows. There are a few options, the best probably being:

EXT2IFS - top link

EXT2FSD - bottom link

what is your insight about Linux file system?
Q. what can you say about linux file system compared to windows'?

A. You should say Linux Filesystem because there isn't a official one
The most common filesystems are ext2 (older), reiserfs(old), ext3(latest)
If you are refering to the directory structure the way Linux stores files then you can compare them
In Windows the root directory is C:\
In UNIX/Linux the root directory is \
In Windows the storage component are devices and accessible to a directory structure
In UNIX to open storage device you have to mount them to a destination before opening them
In terms of fragmentation it is lower because ext3 does not write to disk immediately but throws the data into journal back up
Then calculate the most optimal allocation before writing to final destination

A. Check out SSD Linux.

What is a good file system to use for windows and linux?
Q. I have windows XP on my HD and I am about to install Ubuntu on the same one. Then I have a second HD that i want my home directory to be for Ubuntu, and Windows files. I want to know what file system to use so that it is completely compatible with both windows and ubuntu. I dont need if for any really big files like anything bigger than 2 GB. Thanks!

A. You may have trouble getting ubuntu to use NTFS file directory as your /home partition. I suggest you make your share partition somewhere else. /media/share or something like that. It wouldn't be particularly wise to use a linux /home partition as a windows share anyway, but if you insist on it you will find that even though linux CAN use NTFS as your /home directory, it will refuse to set one up on install. It will give you an error and tell you to use a linux filesystem.

It is, however, possible to use NTFS by adding the partition in fstab and telling it to mount at /home. You will need to create a copy of your user folder into the partition before you mount it. It may be tricky to export your user folder to the new partition, then delete the old one. You'll need to do this as root, from tty1 (ctrl-alt-F1) and you'll want to make sure your username is logged out (and X probably stopped with "/etc/init.d/gdm stop") before you do it.

If this sounds too tricky, don't try it, just make yourself a share partition and don't mount it at /home because like I said, it's unwise to use your /home partition as a share partition anyway.

But yeah, short answer, use NTFS.

Q. I want to install Red Hat Linux Desktop version 4. Please tell me the step-by-step installation and which file system will be best for this O/S?
Like in windows, we have NTFS file system(which has very security features).
Is there any such file system in Linux?
Which file system should i use?

A. Put the CD in the drive, restart the computer and follow the directions. Take the defaults - they're the best choices for a beginner.

How do you determine what Linux file system your using?

Q. When you log onto a Linux system and get to the command prompt, how can you determine which of the many file systems supported in Linux you are using? Is there a command that will identify it?

A. Use fsck with the N option which just show what would have been done, but also show you what type of filesystem it is.

fsck -N /dev/(device-name)

e.g.

fsck -N /dev/hdc2

The 'mount' command wont help if the filesystem isn't mounted, and looking in /etc/fstab wont help because you cant be sure that information can be trusted.

Linux - File system structure between different distros?
Q. I have been reading about Linux distros and I am lost in that kind of "flavors".
Would someone help me understand the main differences in the file system structure in Fedora and how this is compared with the file system structure in Debian?

A. From an end-user perspective there really isn't much difference. Mostly the file system structure (do you mean layout?) is the same. For example, standard programs live in one or more of /bin, /sbin, /usr/bin, /usr/sbin, and custom applications live in /usr/local/bin (but you don't need to worry about any of that, as the PATH variable manages finding them).

Debian-derived distributions provide for some configuration within the directory /etc/default/, and network interfaces are either configured in the file /etc/network/interfaces or by Network Manager.

RedHat-derived distributions (including Fedora) mostly use /etc/sysconfig/ for configuration files, and network interfaces are configured in separate files (one per interfaces) underneath /etc/sysconfig/interfaces/ or by Network Manager

Partitioning a hard drive with two different Linux OS's sharing a common file system?
Q. How do I partition my hard drive with two Linux operating systems so that they have a common shared file system? It was explained to me a long time ago but I forgot. THANK YOU in advance for your time and consideration.

A. First, contrary to what jerry said, two /home/ directories may not be safely shared. There are two many config files, you you may end up with name and version conflicts.

/temp may be safely shared

the swap may be safely shared (but wierd thing can happen on resume from hibernate)

also /boot/ may be safely shared so long as you only configure from one system or the other, and there are no filename collisions (unlikely so no really safe in practice)

To just share media file, I would just create a partition and mount it at /share by editing the fstab of both systems. Then you can make your /home/user/Music a soft link that point to /share/Music. Repeat for Documents, Pictures, Downloads, and whatever else you care to share.

What is the best file system to use on an SSD?
Q. We want to install a Linux system on a SSD and were wondering whether there is a preferable file system choice.
Since the drive does wear leveling, I guess the FS doesn't matter *that* much, but still, fewer write accesses are better. Do some FS manage to get fewer total bytes written per pay load bytes?

A. Check out SSD Linux.

what is your insight about Linux file system?

Q. what can you say about linux file system compared to windows'?

A. You should say Linux Filesystem because there isn't a official one
The most common filesystems are ext2 (older), reiserfs(old), ext3(latest)
If you are refering to the directory structure the way Linux stores files then you can compare them
In Windows the root directory is C:\
In UNIX/Linux the root directory is \
In Windows the storage component are devices and accessible to a directory structure
In UNIX to open storage device you have to mount them to a destination before opening them
In terms of fragmentation it is lower because ext3 does not write to disk immediately but throws the data into journal back up
Then calculate the most optimal allocation before writing to final destination

How to reconize linux file systems on windows?
Q. I have both linux and windows working perfectly, but i'm not able to use the partition created for linux in windows. Linux has no problems in recognizing windows file systems. So please find me a way.

A. generally windows doesn't support linux file system( ext2,ext3 ), but you may be able access using some software like "ext2fs". you can download it from the given link "http://www.fs-driver.org/download.html"

How do you determine what Linux file system your using?

Do I need to defrag a big linux hard drive?
Q. I have a big hard drive (300GIGs) and wonder if I can do something to get better performance out of it. I run Ubuntu Linux. Is there something like de-fragmenting or optimizing the hard drive for linux? The file system is ext3.

A. If you are looking for extra speed I suggest backing up your data and upgrading to Ubuntu 9.04 which supports ext4.

Is there a way to convert NTFS partitions to some Linux Filesystem in place without copying data?

Q. I'd like to convert a NTFS partition to a Linux File system in place without copying the data.

A. I don't think you can convert it directly without backing up your files first on a separate media unless you don't need the files.

GParted can do the conversion from NTFS to a Linux File System.
