I'm using Macbook Pro Mid 2012 on Sierra. It has two partitions without OS partition. Four times those 2 partitions getting corrupted(can't copy files). And I tried to repair disk, And got this message

After I restart my MBP got this.

So as they said I copied the data and reformat it to "Mac OS Extended (Journaled)". Again in 2 days one partition got corrupted. So then I realize File system was "Mac OS Extended (Journaled)" and now it shows only "Mac OS Extended".

Issues having with disk0s4 and disk0s5.

I need to know is this a problem of my HDD drive or a issue with the OS.

  • Please give us more data as to how these got corrupted. Has there been any physical damage? – Rushat Rai Jul 2 '17 at 13:41
  • No some times MBP stucked. And sometimes it stuck when Time Machine backup preparing Then I restart by pressing Power Button. Then it got corrupted. Again when Time Machine backuping I restarted. Those two are the known instances. – Rash Mendis Jul 2 '17 at 14:42
  • hmmm this is pretty puzzling. Have you tried running first aid from recovery? – Rushat Rai Jul 3 '17 at 12:02
  • Yes that also same – Rash Mendis Jul 3 '17 at 12:08
