Problem Formatting External HDD

[midgetski]

I have a WD My Book with two FAT32 partitions. I am trying to use Disk Utility to format/erase one of the partitions to use HFS+ however the Disk Utility hangs and when I quit the program the volumes become unreadable (though I have managed to rebuild them in windows). Anyone had this problem? Are there any other programs which I could try instead of Disk Utility?

I want to avoid destroying/formatting the other partition.

This is from the log file:

**********
Disk Utility started.

Preparing to erase : “Time Machine”
The volume could not be made bootable during erase
This new volume may not be bootable in the future
newfs_hfs: /dev/rdisk1s5: No such file or directory

Volume Erase failed with the error:

The underlying task reported failure on exit
Erase complete.

Mounting Disk
Erase complete.

I somehow managed to fix it. Not entirely sure how though. I went back into windows and reformatted the partition and added a couple of files. In Disk Utility, I then erased the partition and selected the option to write zeros to the partition and it worked.
