If you don't already have a current backup, you must back up your data before you take the above step. You may be able to back up, even if the system isn't fully functional. Ask if you need guidance.
Directory corruption in a MacOS journaled volume is always the result of a drive malfunction, or (less likely) of a low-level bug in OS X. It's not caused by power failures, system crashes, or anything else. You might choose to tolerate such a malfunction once in the life of a drive. If it's repeated, the drive must be replaced, or there is some other hardware fault that needs to be corrected. Ignoring repeated directory errors will result in data loss.

Jun 12, 2016 8:24 AMby Trapt-Cat,I am currently in recovery mode and have run first aid and no problems show up.
I tried to run verify and repair permissions through terminal earlier and there were quite a few permissions that varied but once I used the repair command line it repaired most if not all of them.
Even though it says theres no problems in first aid I still have the same issues as initially stated after waking from sleep.

Jun 12, 2016 8:45 AMby Linc Davis,HelpfulYou may be dealing with a damaged SATA cable. The cable is fragile, and it, rather than a failing hard drive, could have been the cause of the original problem.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keep your confidential data secure during hardware repair.
Apple recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.

Jun 13, 2016 7:57 AMby Trapt-Cat,So I went to the apple store yesterday and the Tech there said my drive itself was failing and that the SATA cable seemed fine. However, I ran a few programs such as SMART Utility, Drive Disk, and Etrecheck. Both SMART Utility and Drive Disk show an error called "UDMA CRC error count" and its really high (and increasing each time I run it). It's description within the program says that it could be a problem either with the power supply or data cable. So are they saying it could be a problem with my power cable or my SATA cable? So rather than JUST a failing drive, could it be a combination of a failing drive and failing SATA cable? Thank you!
