Intel 600p SSD problem with TRIM

Hello,

Available:

ASUS_PRIME_Z270_P

M. 2 x 4 PCI-Express 3.0 Intel SSD 128 Gb SSDPEKKW128G7X1 600p

Windows 7 SP1 + hotfix for NVMe

Driver: Standard controller NVM Express (stornvme.sys)

Question.

Can not understand, running TRIM or not. When you restart, after a short wait, TrimCheck displays the following:

" First 16 bytes: AE 41 07 45 6C 5F 27 38 EC 17 A0 84 21 52 38 9F...

Data is neither unchanged nor empty.

Possible cause: another program saved data to disk,

overwriting the sector containing our test data.

CONCLUSION: INDETERMINATE.

Re-run this program and wait less before verifying / try to

minimize writes to drive C:."

Codes in the “First 16 bytes:” are constantly the same, instead of 00. What's the problem?

Thankful in advance.
