Is there way to read sectors from SATA drive without ECC correction

I know, there was such possibility like that in old ATA standards: "READ LONG" command produced LBA sector + ECC payload. sg_read_long supports in in linux, but the command is obsolete for quite a long time, so I'm not surprised, that my HDD does not implement it.

root@ubuntu:~# sg_read_long --lba=2118229 /dev/sdc
sg_read_long: issue read long (10) to device /dev/sdc
    xfer_len=520 (0x208), lba=2118229 (0x205255), correct=0
  SCSI READ LONG (10) command not supported
root@ubuntu:~# sg_read_long -v --16 --lba=2118229 /dev/sdc
sg_read_long: issue read long (16) to device /dev/sdc
    xfer_len=520 (0x208), lba=2118229 (0x205255), correct=0

Here is hdparm dump too:

I want to read several sectors without ECC to create better dump of half-dead HDD.

Another part of story is ATAPI-8 command set. It declares SCT Read/Write Long command that works when when IDENITFY DEVICE data word 106 bit 12 is cleared to zero according to T13/1699-D Revision 6a, Working Draft AT Attachment 8 - ATA/ATAPI Command Set (ATA8-ACS). This bit is set to 1 iff Device Logical Sector longer than 256 Words.

OTOH, it works only with 512-byte sectors, so I don't understand if it works when ECC/CRC is applied to 4k sectors.
