Start-up application was deleted

Hi. I just bought WD My Passport Ultra 2 TB. However, when I tried to format it to exFAT, I have to format and erase all the data in it. Accidentally I deleted all the start-up applications from WD (WD Apps for Mac, WD Apps for Windows, User Manual, Backup, etc.). All the files that was contained in the start up of my hardisk was deleted. I am a liitle bit panick now because without that application I can’t back up and install apps for mac or windows. Can you help me? Maybe there is a way to get the start-up data/application back?

I am also wondering how to set the backup in my harddisk automatically. Thank you.

Hi, you can get all the information that was on the drive from http://support.wdc.com.

What kind of backup you want to do? The reason for my asking is that you might use WD’s software to accomplish it or maybe a third party software might be needed.
