Need help with restore partition

[Artus2000]

Hi all,

Today I found that my iMac 27 late 2014 have SSD installed but I didn't see it on my Disk Utility - I only saw 1TB HDD called Macintosh HDD. Of course I am stupid, because it wasn't separate drives but one hybrid drive - fusion drive.

But I thought it is strange and I tried to solve this and after reading some articles about similar issues regarding troubles with SSD finally I ran Internet Recovery and in the Terminal I erased SSD using this command (diskutil eraseDisk APFS SDD /dev/disk0).

Now I see SSD but unfortunately I don't see my HDD with all my data!
I don't know why when I erase disk0 it had influence for other disks.

Is there any chance to restore my HDD?

Regards,
Artus

A "fusion" drive is actually TWO drives:
- a small SSD portion
and
- a larger HDD portion

The two drives are "fused together" with software, and the data is "mixed up" between the two drives.

If this fusion is somehow broken, all the data on BOTH drives is lost.

So... unless you have a backup... the answer is NO... you're NOT "getting the data back". It's gone, most likely forever.

Next time... keep a backup!
