Whenever I have an SSD (crucial mx100 or samsung 850) as my internal hard drive, my macbook has problems with sleep/wake. If I unplug my macbook and let it sleep, the hard drive does not wake up. It will work for about a second then it'll freeze for a few seconds and quickly flash a white screen and reboot. This also happens when I close the laptop while it's plugged in and I try to reopen it. Sometimes it will happen randomly after a few hours of using the computer (and possibly letting it sleep in-between).
Some solutions I tried:
- Reseting SMC
- Installing OS X via USB and installing it as internal hard drive
- Reinstalling OS X
- Repairing the drive in Disk Utility
Solutions that worked at first (for a few days), but eventually failed:
- Replacing the hard drive cable. (No problems for about a month)
- Preventing the drive from going to sleep in settings
I can boot the SSD from a USB enclosure perfectly fine. When I have the SSD as my internal drive, I sometimes get the prohibitory sign and the file system will appear corrupted. But the minute I put the SSD in a USB enclosure, everything works perfectly again.
What is going on? Anyone know?
Also, I have high data error counts in DriveDx with the SSDs, however the stock hard drive works perfectly fine as my internal drive.
