Attempting to hand over my external HDD to a friend of mine for his use, I deleted all the files in my external HDD amount to freeing space close to 470GB. I did it all in my mac. For all I remember, some files I deleted using Windows machine and some others using my Mac machine.
I tried finally formating or doing quick erase using the disk util. Since then, the HDD is showing up only 149Gb as the total capacity of my external HDD.
Not sure what has happened. Please help me recover the full capacity of the HDD.
Thanks in advance..
