HDD read errors: "Data phase CRC error detected"

I have a couple of powered USB -> SATA adapters which I use to connect 4Tb Seagate Barracuda HDDs (with 12V/2A power adapter connected to the adapter). From time to time I see error messages like the following ones in system's logs:

kernel: sd 4:0:0:0: [sdb] tag#24 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=0s

It doesn't seem that there is a real problem with HDDs (which are fairly new: smartctl reports 100-200 power-on hours): long SMART test on those drives passes without errors, disks are fully readable and there is no data loss (everything in HDDs is 'md5sum'ed and integrity checks pass successfully). When I try to re-read sectors reported in the logs with hdparm - read succeeds without additional error messages. For example:

hdparm --read-sector 7525970816 /dev/sdb

/dev/sdb:
reading sector 7525970816: succeeded
c8e9 d9ca d67b abe8 ea29 c2d9 4eeb bca5

...

Also, sometimes when I connect a HDD, logs are filled up with this kind of messages: when disk is in use, such message appears approximately every second. Disconnecting/reconnecting the adapter solves this problem (and causes those errors to appear only once in a while).

The USB->SATA adapters are identified as:

Bus 002 Device 014: ID 7825:a2a4 Other World Computing External SATA Hard Drive Adapter cable PA023U3
Bus 002 Device 015: ID 7825:a2a4 Other World Computing External SATA Hard Drive Adapter cable PA023U3

What can be a cause for those messages, and how they can be eliminated completely?

nb. that eg. https://wiki.archlinux.org/title/TLP#USB_autosuspend or https://wiki.archlinux.org/title/Laptop … utosuspend will override this at runtime.
