USB adapters that contain a SATA controller chip that supports ATA pass through for secure erase/HPA/DCO/smart data #128

Oh yeah, very interested here for the result. If true than I would think UASP is doing the magic here and be responsible for making it work. If that's the case then any UASP adapter should work pretty well. We all have been buying the wrong adapters over the years :( For later reading...

For reference this USB to SATA adapter contains a ASM1051E chip

Here's another that works perfectly with nwipe's HPA/DCO detection, i.e hdparm -N, hdparm --dco-identify, --dco-restore It's running the following chip:

@Firminator Thought I'd start building that table of USB adapter that provide full support for the commands we need for HPA/DCO and secure erase and also a table of USB adapters that don't support ATA pass through. #128 (comment) |

Updated the table above with new Unitek USB M.2/SATA adapter that fully supports HPA/DCO and secure erase via USB for the SATA connection. https://amzn.eu/d/08vWdHXW |

Table of USB adapters that support ATA pass through, specifically drive configuration overlay (DCO), host protected area (HPA) detection and setting a password and commanding a ATA secure erase by the drives firmware. Also a list of those that don't provide this ability.
If you have a USB adapter that you would like added to either table, please add a comment to this discussion, with all the details as required in the table. These are the tests you want to do:
Why would I want a USB adapter with ATA pass through?
If the adapter doesn't support ATA pass through then ShredOS/nwipe/hdparm won't be able to detect hidden sectors, or perform secure erase using the drives own build in eraser in firmware. Drive temperature won't be visible and smart data won't be retrievable for the PDF reports.
These USB adapters allow ATA passthrough. (Recommended for ShredOS and recent Linux Distros)
Note 1: The Unitek S1232A will respond with
/dev/sda: Unknown USB bridge [0x152d:0xb581 (0x4403)] Please specify device type with the -d option.
Using the commandsudo smartctl -d sat -a /dev/sda
will produce the smart data.These USB adapters allow some ATA passthrough but have some special requirements and may not provide ATA pass through on recent Linux distributions. They are generally older and may not support USB V3.x so may be slower. (NOT RECOMMENDED)
These USB adapters DO NOT allow ATA passthrough (NOT RECOMMENDED for hidden sector detection or secure erase)
