Convert windows drive or disk file system from FAT32 to NTFS without losing data

Hi all,

I had a problem with my external hard disk when copying some 25GB file.

I had troubleshoot the problem and understand that, my hard disk file system is FAT32, which can only copy max 4GB single file size

 

I was thinking without losing my data, how can I change the file system, so that, I copy more than 4GB sized single files

Then I come across the following commands in Windows

1) chkdsk : Check disk

2) convert : Convert disk file system

 

chkdsk command

Syntax

cmd> chkdsk volume_letter: [options]

Example

Checks for disk errors and fix it

cmd> chkdsk I: /f

 

convert command

Syntax

cmd> convert volume_letter: FS:NTFS [options]

Example

Convert volume from FAT to NTFS in verbose

cmd> convert I: /FS:NTFS /V

 

Possible Errors with solutions

Insufficient Memory

Reason

Nearly 4 GB files in existing FAT32 system

Solution

Move the files to local drive, do chkdsk and then convert

Mounting (Connect) external disks in Ubuntu

Hi everyone,

Most of the present Ubuntu Operating Systems will auto-mount the internal/external disks.

In some cases that may not be done automatically. In that situation, you can manually mount the media to the Ubuntu.

Here comes the mounting of external disks like HDD, Pen-drive etc in Ubuntu. 

Procedure:

1) Open terminal
2) Type sudo su in the terminal
3) Enter the password
4) Now you will be in super user mode i.e. # mode
5) Go to the desktop or some folder where you want to create a folder for mounting
    ex: # cd /home/user1/Desktop
6) Create a directory
    ex: # mkdir ExtrnDisk
7) Type the following command for NTFS disks
    # mount -t ntfs-3g /dev/sdb1 ExtrnDisk/ (FAT32 -- vfat)

    Type the following for rest of the disks
    # mount /dev/sdb ExtrnDisk/
8) Now you can see the drive contents mounted to ExtrnDisk folder

Write Protect your pen drive from copying, deleting and etc.,

Hi everyone,

Today one of my friend asked me "Why I cann't copy the data to my USB Pendrive". It is showing message like "Remove the write-protection or use another disk". Can you help me to resolve? "

I just checked and came to know that, the pen drive is write protected. Only we can copy the content from pen drive but can't do deleting and copying to pen drive.

• To remove the write protection, please follow the steps below.
• Open run window by pressing windows + R or start->run
• Type regedit.exe and click on "Ok" button or Press Enter button.
• Please go to the following path
    \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
• If there is no WriteProtect key, please create a DWord key with name WriteProtect
• To enable write-protect, please give "1" as key value
• To disable write-protect, double click the WriteProtect key and give value as 0 

Hope you will protect your pendrive.
