FAT / NTFS Drive Issues


At the initialize database cluster page during the PostgreSQL installation an error message occurs. It states the database must be on NTFS formatted volumes, not FAT volumes. 

Note:  This is happening because the hard drive is formatting in FAT and not NTFS.

Note:  This is for Advanced PC Users Only!!!



WARNING!!! - Changing a Partition Type on any drive carries risks of complete loss of data.  Proceed with Caution!


Abort the current installation and close all windows and programs down. Then follow the instructions below:

To convert a FAT partition to NTFS, perform the following steps.

  1. Click Start, click Run, type cmd and then click OK.  
  2. At the command prompt, type in CONVERT [driveletter]: /FS:NTFS. Replace [driveletter] with the letter of the drive that is being converted. For example, if the c drive is being converted, type the following:


     3.  Press ENTER.

Convert.exe will attempt to convert the partition to NTFS.

     4.  Restart the installation. Everything should be fine.

Note: Performing this will not format your drive or cause you to lose any programs or files. The chance of corruption or data loss during the conversion from FAT to NTFS is minimal. It is best to perform a full backup of the data on the drive that it is to be converted prior to executing the convert command.
