1 Issue with replacement Hybrid SSD drive
I replaced my internal original 320 GB drive with a new 1TB Hybrid SSD drive and recovered everything from a Time Machine backup. So far so good, no problems there.
However, when I keep my Mac running for a day or so it starts having issues with not finding files, some application fail to start. When I try to restart the machine would not restart from the Apple menu, I have to hard boot the machine.
I am wondering whether there could be something wrong with the drive or whether I have some other issue. I saw the reports from other users being totally happy with their replacement drive, and I would be too, if the Mac was behaving normally.
Any advice someone can give? Otherwise I might have to resort to getting another drive to see whether that fixes the problem.
Many thanks in advance.

Can you give us the last four digits of your serial number as well as the make & model of your hybrid drive. Without knowing these one would only be guessing.

Here is the disk description ST1000LM014-1EJ164, 1TB, D4E9011F-A060-368A-93FB-12AFCEE3CC68, SMART status is verified. Seagate Laptop SSHD. Don't know which is the Serial Number, but here are a few choices: 5000C50072AC2A05 or SN: W3814JVD
Hope that helps in diagnosis of the patient :-)

Can't ID your system with either number. Go to about this system and get more info you'll find it there.

It appears that the system stops seeing the disk after a certain amount of time, about a day or so, as I cannot see the disk under storage. Once I re-boot the system can see it, and there I see three volumes:
EFI, Capacity: 209.7 MB;
Macintosh HD D4E9011F-A060-368A-93FB-12AFCEE3CC68, Capacity: 999.35 GB, Available: 704 GB; Apple_HFS and a
Recovery HD 9D835AF3-2D76-3B0C-80F8-38896C294625, Apple_Boot, 650 GB
This is under SATA/SATA Express. Don't know where else to look for a number that can help.
What could cause a system to not see the disk anymore?
