Hi anyone out here,

I have encountered a weird problem recently after installing and then uninstalling Ubuntu 18.10 on my MacBook Pro (Retina, 15-inch, Mid 2015). I uninstall Ubuntu by simply erasing the hard disk of it. I have installed and uninstalled Ubuntu successfully on my old macbook pro 13" before Apple's new file system APFS when everything is alright. After this time I remove the Ubuntu from my macbook, some hard drive volume, 32 GB, is missing. This amount is exactly the same as the "swap" volume I gave to my Ubuntu system when I installed it. And it doesn't shown up anywhere on my Disk Utility. I have also run the "diskutil list" on terminal but didn't find it as well. Can I possibly get back those lost volume by any mean?



in the terminal windows it shows as:
