We’re observing that the SATA instructions are freezing/responding after very very long time in AHCI mode with HDD.

 

Is that this a recognized subject?

 

Evaluation:

 

The appliance is making an attempt to fetch the data from HDD utilizing SATA ATA command. To get the data software is sending instructions utilizing win32 DeviceIoControl API and IOCTLs. Nevertheless, the response is frozen/very gradual.

 

RIAD Mode check. (HDD & M.2) – Go
AHCI Mode check. (Solely M2) – Go
AHCI Mode check. (Solely HDD) – Freeze/taking too very long time.
AHCI Mode check. (HDD & M2) – Freeze/taking too very long time.

 

out of band (OOB) indicators is sending COMRESET, COMINIT and COMWAKE in AHCI Mode. OOB Sequence sort is sending SATA COMRESET type host to the gadget earlier than sending instructions which is taking lots of time to course of. out of band (OOB) indicators is sending solely COMWAKE in RAID Mode.
