Hi,

my Toshiba HK4R Series SSDs report wrong values for Total_LBAs_Written:

Info:

# smartctl -q noserial -i /dev/ada0
smartctl 7.4 2023-08-01 r5530 [FreeBSD 14.2-RELEASE amd64] (local build)

=== START OF INFORMATION SECTION ===
Model Family:     Toshiba HK4R Series SSD
Device Model:     TOSHIBA THNSN81Q92CSE
Firmware Version: 8ENP6101
User Capacity:    1,920,383,410,176 bytes [1.92 TB]
Sector Size:      512 bytes logical/physical
Rotation Rate:    Solid State Device
Form Factor:      2.5 inches
TRIM Command:     Available, deterministic, zeroed
Device is:        In smartctl database 7.3/5625
ATA Version is:   ACS-3 (minor revision not indicated)
SATA Version is:  SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s)
Local Time is:    Wed Jan  1 12:33:12 2025 CET
SMART support is: Available - device has SMART capability.
SMART support is: Enabled

Sector size is reported as 512 byte (as usual):

# smartctl -q noserial -i /dev/ada0 | grep "Sector Size"
Sector Size:      512 bytes logical/physical

But the unit of Total_LBAs_Written apparantly is 32 MiB:

# smartctl -q noserial -A /dev/ada0 | grep Total_LBAs_Written
241 Total_LBAs_Written      0x0012   100   100   000    Old_age   Always       -       1233996

# dd if=/dev/zero of=/dev/ada0 bs=32m count=4

134217728 bytes transferred in 0.319625 secs (419922367 bytes/sec)

# smartctl -q noserial -A /dev/ada0 | grep Total_LBAs_Written
241 Total_LBAs_Written      0x0012   100   100   000    Old_age   Always       -       1234000

# dd if=/dev/zero of=/dev/ada0 bs=32m count=4
4+0 records in
4+0 records out
134217728 bytes transferred in 0.311620 secs (430710227 bytes/sec)

# smartctl -q noserial -A /dev/ada0 | grep Total_LBAs_Written
241 Total_LBAs_Written      0x0012   100   100   000    Old_age   Always       -       1234004

I've also noticed that CrystalDiskInfo shows other values and I've found this: https://github.com/hiyohiyo/CrystalDiskInfo/blob/bdf4e44cc449225ec814c011c5d6c537da3c71fc/AtaSmart.cpp#L5579
They are setting the unit for specific Toshiba SSDs to 32 MiB and to 1 GiB for others:

if (modelUpper.Find(_T("TOSHIBA")) >= 0 && asi.IsSsd)
	{
		flagSmartType = TRUE;
		if (asi.Model.Find(_T("THNSNC")) >= 0 || asi.Model.Find(_T("THNSNJ")) >= 0 || asi.Model.Find(_T("THNSNK")) >= 0
		||  asi.Model.Find(_T("KSG60")) >= 0
		||  asi.Model.Find(_T("TL100")) >= 0 || asi.Model.Find(_T("TR150")) >= 0 || asi.Model.Find(_T("TR200")) >= 0
		)
		{
			// TOSHIBA HG3
			// https://crystalmark.info/bbs/c-board.cgi?cmd=one;no=1106;id=diskinfo#1106
			// TOSHIBA KSG60ZMV
			// https://crystalmark.info/board/c-board.cgi?cmd=one;no=2425;id=#2425
			asi.HostReadsWritesUnit = HOST_READS_WRITES_32MB;
		}
		else
		{
			asi.HostReadsWritesUnit = HOST_READS_WRITES_GB;
		}
	}

Could it be renamed to Total_32MiBs_Written in drivedb?

I've found it in drivedb.h and changed it locally on my system:

  { "Toshiba HK4R Series SSD", // TOSHIBA THNSN8960PCSE/8EET6101
    "TOSHIBA THNSN8(120P|240P|480P|960P|1Q92)CSE",
    "", "",
    "-v 167,raw48,SSD_Protect_Mode "
    "-v 168,raw48,SATA_PHY_Error_Count "
    "-v 169,raw48,Bad_Block_Count "
    "-v 173,raw48,Erase_Count "
    "-v 241,raw48,Total_32MiBs_Written "
    "-v 242,raw48,Total_32MiBs_Read "
  },

Should/could I create a pull request for this change?

Thanks for the info.

Please provide a full smartctl -x -a output of this device. Don't use only -a as it only provides legacy (and officially obsoleted) SMART information. Check Logical Sectors Read/Written from vendor independent Device Statistics (if supported) for consistence with the 32MB factor.

This repo is still a R/O mirror of the upstream SVN repo at SF. So please add a patch for the ChangeLog file to your PR.

And here is a check of Logical Sectors Written. Writing 4k writes 8 logical sectors as expected. Also writing 32M writes 65536 logical sectors.
