How to convert a UDF external drive to a FAT32 or NTFS fmt

April 15, 2017 at 23:09:53
Specs: Windows 7
I have a WD My Passport External drive. It would not give me permission to back up files on it, so I formatted it using Windows 7 format tool. Now it shows that the whole disk is full (blue) and the file system has changed to UDF. Please help me convert it back to FAT32 / NTFS

You need to check your drive listings again. You are looking at your CD/DVD drive. There is no way your external hard drive is formatted to a UDF format.

If Windows Explorer isn't giving you enough information, look in Disk Management for the correct information.

@PhotonLight

Download, unzip, install, and run the "WD Quick Formatter for Windows" if running Windows
http://download.wdc.com/misc/WD_Qui...
OR,
"WD Quick Formatter for Mac" if running Mac OSX 10.5, 10.6, 10.7, 10.8, or 10.9 (Leopard, Snow Leopard, Lion, Mountain Lion, or Mavericks).

It should not be necessary to use third party programs to format an external drive. Windows inbuilt function works perfectly well.

Unplug your external drive and note the drives showing in "Computer", in particular their drive letters. Now plug in your external and look again. The drive that suddenly appears is the one you need to format. You can double check by looking at its contents. Format is on the list when you use your mouse right click.

Always pop back and let us know the outcome - thanks

Thanks so much for responding to my question. I checked my listings again. I went into Computer - Manage - and it says clearly that there are three healthy NTFS partitions on my laptop's hard drive but the My Passport External 1 TB drive is listed as UDF which means for all practical purposes, the unit cannot be used any more. Very grateful for your help THX 1138, TechDos and Derek. I appreciate your kindness in taking time off to try and help me

There is something wrong. Try formatting it again from Windows. If necessary try the formatter suggested by TechDOS but I can't vouch for it personally.

You could also try formatting it from Windows on another computer. If it still comes up as UDF then it must be faulty.

Always pop back and let us know the outcome - thanks

Do you use other operating systems besides Windows?

You must have selected that partition type when formatting. UDF can be used on multiple platforms. Evidently the drive acts like a CDRW/DVDRW.

You need to delete the partition/s on the external and recreate them. Then you can format using FAT32 or NTFS. Go to Windows disk management to perform those operations.

Be aware that any data currently on the drive will be lost.

Program is for External Western Digital - My Passport HDD, And Specially for External HDD By Manufacturer !

@PhotonLight
Use Manufacturer's program.
Use Original Cable of exHDD (USB3.0/2.0).

The WD program should be completely safe for the drive BUT is also should not be necessary. Open Disk Manager (as noted above) find the drive on the list, right click on it and select Delete Partition. When the process is compete, right click again and select Partition and use all of the available space for the new partition. When complete, right click again and select Partition, Then select NTFS if only using on Windows or Linux, or FAT32 if you may want to use with Mac systems, cameras, or anything not compatible with NTFS.

You have to be a little bit crazy to keep you from going insane.

TechDOS (re #7)

Yes, I did suggest using the WD program if another try using Windows failed. See #5.
