Yes I do hear You, but how do I create partitions when the drive is NOT recognized by UAE when booted up.
The symptoms you describe ("Drive does not show") don't mean that UAE doesn't recognize the drive, they mean that AmigaOS doesn't recognize the drive. This is caused by the drive not being partitioned yet.
The tool for managing partitions is called HDToolbox and can be found in SYS:Tools/ after the OS has been installed to a hard disk. Otherwise it's either on the "Workbench" or the "Install" floppy disk.
