Micron 1100 SATA SSD: Total Host Reads/Writes converted wrong #129

Closed iisti closed 3 years ago

iisti commented 3 years ago

​I noticed that CrystalDiskInfo 8.12.5 is probably converting Micron 1100 SATA SSD disk's Total Host Reads/Writes wrong.

CrystalDiskInfo 8.12.5 shows these numbers for my disk.

Host Reads  : 1168593554 GB
Host Writes : 1785273526 GB

S.M.A.R.T info

F1 100 100 __0 000D4D2396CB Total LBA Write
F2 100 100 __0 0008B4EA5255 Total LBA Read

After converting HEX to DEC

000D4D2396CB = 57128752843
0008B4EA5255 = 37394993749

I also checked with smartmontools the Total LBAs.

241 Total_LBAs_Written      0x0033   100   100   000    Pre-fail  Always       -       57128815318
242 Total_LBAs_Read         0x0033   100   100   000    Pre-fail  Always       -       37395014575

I converted the LBAs with this calculator. https://www.virten.net/2016/12/ssd-total-bytes-written-calculator/

These numbers are a bit more believable.

Total_LBAs_Written  57128815318 = 27241 GB
Total_LBAs_Read     37395014575 = 17831 GB

It seems that the CrystalDiskInfo has error in the conversion.

Maybe fixed by CrystalDiskInfo 8.12.6.

I tested with 8.12.6 and can confirm that issue has been fixed. micron1100_sata_ssd_text_copy_fixed.txt
