开头 S6 是高危大家应该都知道了，但我还是想尽可能更精确地确定大概的批次范围，所以就有了以下不完全统计
太长不看：以下为各型号存在已知中招案例的序列号开头，多集中在写入量 < 15T 发生，整体集中于 21 年全年 （所以第八位以 R 为主），但仍存在少数 20 年末（第八位为 N），22 年（第八位为 T）和 23 年（第八位为 W）的案例
更新：870 EVO 型号将从 2022 年 11 月开始采用修订的 V6 工艺生产
出处： https://semiconductor.samsung.com/consumer-storage/support/tools/
已知最近生产时间的中招案例：
22 年 1 月产的 PM9A1 出处： https://www.chiphell.com/thread-2435363-1-1.html
22 年 4 月产的 970 EVO PLUS 出处： https://tieba.baidu.com/p/8151516105
23 年 2 月产的 970 EVO PLUS 出处： https://tieba.baidu.com/p/8302583639
22 年 11 月产的 980 PRO 出处： https://www.bilibili.com/video/BV1pA411d7sT
因为涉及多个型号和不同代的主控，且例如 PM9A1 也覆盖了出厂固件为 7301Q / 7401Q 及各种 OEM 固件的批次，暂时可以判定跟主控和固件相关性不大
更正：三星已确认 980 PRO 固件版本 3B2QGXA7 的问题，并建议用户将所有 980 PRO 驱动器上的固件更新到最新版本 （5B2QGXA7） 以防止问题发生。
补充：三星表示，执行固件更新应该可以防止这些故障，但它不会扭转已经出现故障的驱动器上的问题。
出处：Critical Samsung SSD Firmware Update
PM9A1 目前最新 7801Q 固件： https://www.chiphell.com/thread-2495281-1-1.html
PM9A1 7701Q/7702Q 固件： https://www.chiphell.com/thread-2477782-1-1.html
PM9A3 目前最新 5602Q/7302Q 固件： https://www.chiphell.com/thread-2457407-1-1.html
990 PRO 最新 1B2QJXD7 固件： https://download.semiconductor.samsung.com/resources/software-resources/Samsung_SSD_990_PRO_1B2QJXD7.iso
870 EVO 也是重灾区，作为 SATA 盘对应的 SMART 项为 BB (Uncorrectable Error Count) / C3 (ECC Error Rate)，且在最新的 SVT02B6Q 固件中添加了 FC 项 （CDI 未收录，显示为厂商特定项目），具体计数意义未知，但最好为 0
更新：根据 PM863a Datasheet，FC （十进制 ID 为 252）应该对应 "Read ECC Count"
PS：感谢坛友 @tide~ 收集的 CDI 截图
870 EVO 序列号出处: https://www.techpowerup.com/foru ... e-to-failure.291504
PM9A1: S63JNF0R / S63JNX0T / S64JNE0R / S64SNE0R / S65XNF0R / S675NF0R / S676NF0R / S676NX0R / S677NF0R / S6W7NF0R（S677NF0R 为重灾区）
PM991a: S6F5NJ0R
870 EVO: S5Y2NJ0N / S5Y2NJ0R / S5Y3NF0R / S5Y3NG0R / S621NG0R / S625NJ0R / S626NF0R / S626NJ0R / S626NX0R / S62BNJ0R / S62CNF0R / S62CNJ0R / S6BANJ0R / S6BBNG0R / S6BCNG0R / S6BCNJ0R / S6PNNJ0R / S6PTNJ0R / S6PTNZ0R / S6PUNF0R / S6PXNJ0R

970 EVO PLUS: S6P7NG0R / S6P7NF0T / S6P1NS0W
980: S649NF0R / S649NF1R / S649NG0R / S649NJ0R / S649NX0R / S64ANG0R / S64DNF0R
980 PRO: S5GXNF0R / S5GXNF0T / S5GXNG0N / S5GYNX0R / S69ENF0R / S69ENG0R / S6B0NC0R / S6B0NG0R
990 PRO: S6Z1NJ0T
企业级 SSD 也有报告，不过样本数非常少，暂不确定是否为同一原因
PM9A3： S63UNE0R
坛友两例：挂一下之前某位坛友推的PM9A3 3.84t大船 咸鱼的9a3变成30个1g了，有0E问题，挂个商家名大家要小心
PM1733： S4YPNA0R （罕见，根据某 AFR 统计数据估计中奖率 < 0.5%）
建议序列号在上述范围内但 SMART 暂未报 0E 的也用 Samsung Magician 完整扫描检测一次，存在扫描后才增加 0E 计数的案例 （PM9A1 等无法调用 Magician 的 OEM 盘可用 DiskGenius 或其他软件的坏块检测功能代替）
注意：请尽量在完整扫描前做好重要数据备份，如果闪存本身已经出现问题，有概率存在扫描过程中掉盘的情况
0F 计数量大 / 计数增加与本次事件无关，请勿焦虑：NVMe 控制器命令执行失败的情况下 0F 计数都可能增加，而这可能只是因为一些无关紧要的原因导致的
例如- 0x2002(INVALID_FIELD: A reserved coded value or an unsupported value in a defined field)
无论是否中招，重要数据建议使用 「3-2-1 原则」备份：
3：存储 3 份完整文件，一份原件加上两份拷贝。
2：将文件起码保持在两种不同的介质上。
1：将一份拷贝保存在异地。
--- 序列号解读相关 ---
已知 S4 / S5 开头也可能报 0E，因此数据仅供参考 顺带希望能找到序列号规律看看能不能解码对应位含义，这样以后也没必要全打码了
目前已知位的解读方法：例如 S6P7NG0R，S6 能够推测出是新主控版本，P7 对应 970 EVO PLUS 1TB， G 对应韩国产，R 对应 2021 年产
有些旧贴归档看不到了，所以收集不太完整，还请见谅 有很多中招但是序列号全部打码了也无法列出
欢迎分享补充
补充：根据对大量 PM9A1 的观察，序列号第九位对应出厂月份 （16进制），如 S676NX0T7 出厂年月为 2022.07
也适用于其他型号，如我的 980 PRO with Heatsink S6WRNS0RB 对应 2021.11 （10进制的 11 转换到 16 进制就是 B）
引用 88# 楼 tide~ 的总结：
三星固态硬盘贴标的S/N的第8位和第9位用于表明生产日期：
第8位表示年份，2008-Q、09-S、10-Z、11-B、12-C、13-D、14-F、15-G、16-H、17-J、18-K、19-M、20-N、21-R、22-T、23-W；
第9位表示月份，1表示1月，2表示2月，3表示3月....当大于9时开始用字母表示，A表示10月，B表示11月，C表示12月
第四位对应容量，如 S674 为 256G， S675 为 512G， S676 为 1024G， S677 为 2048G
不同型号第三、四位对应的数字 / 字母并不通用，如 980 PRO 2TB 对应的是 S69E， 980 PRO with Heatsink 2TB 对应的是 S6WR
序列号第六位和第七位对应出厂地，以下为观察到的第六位对应字母：
Made in Korea: A C E G J S(0-3) W
Made in China: B F X (SA)
Made in Thailand: M Z
Made in Vietnam: L U
第七位通常为 0，少数为 1-3，850 系列 SA 产地为中国，疑似为特例 （对应 EA 产地为韩国） 具体含义不明
第二位跟闪存代数高度相关（出现时间跟闪存换代时间表基本吻合），但仍缺少相关证据证明其指闪存代数，且疑似存在一些反例 （例如在 2021 年 8 月之后出厂的部分 970 EVO PLUS 又换回 S4 的操作，S5 和 S6 混用的 980 PRO），有待商榷
考虑到 990 PRO 序列号仍为 S6 开头但使用 V7 NAND，基本可以排除第二位为闪存代数的可能性
--- Translated with DeepL ---
TLDR: Following are the beginning 8 bits of the serial number of each model with known hit cases, usually happened when the write volume < 15T, most are manifactured in 2021 (so the eighth digit is mainly R), but there still exists a few cases in 2020 (i.e. the eighth digit is N), 2022 (i.e. the eighth digit is T) and 2023 (i.e. the eighth digit is W)
Because it involves several models and different generations of controllers, e.g. PM9A1 also covers the factory firmware 7301Q / 7401Q and various OEM firmware batches, we can temporarily determine that there is little correlation with the controller and firmware, but it is still recommended to upgrade your SSD to the latest firmware
PM9A1: S63JNF0R / S63JNX0T / S64JNE0R / S64SNE0R / S65XNF0R / S675NF0R / S676NF0R / S676NX0R / S677NF0R / S6W7NF0R (S677NF0R is most affected)
PM991a: S6F5NJ0R
870 EVO: S5Y2NJ0N / S5Y2NJ0R / S5Y3NF0R / S5Y3NG0R / S621NG0R / S625NJ0R / S626NF0R / S626NJ0R / S626NX0R / S62BNJ0R / S62CNF0R / S62CNJ0R / S6BANJ0R / S6BBNG0R / S6BCNG0R / S6BCNJ0R / S6PNNJ0R / S6PTNJ0R / S6PTNZ0R / S6PUNF0R / S6PXNJ0R
970 EVO: S464NB0K / S465NF0K / S466NF0K / S466NX0K / S466NX0M / S5H7NS0N / S5H9NS0N
970 EVO PLUS: S6P7NG0R / S6P7NF0T / S6P1NS0W
980: S649NF0R / S649NF1R / S649NG0R / S649NJ0R / S649NX0R / S64ANG0R / S64DNF0R
980 PRO: S5GXNF0R / S5GXNF0T / S5GXNG0N / S5GYNX0R / S69ENF0R / S69ENG0R / S6B0NC0R / S6B0NG0R
990 PRO: S6Z1NJ0T
It is recommended that people who have SSDs with serial numbers in the above range but SMART does not report 0E also use Samsung Magician to do a full diagnostic scan at least once, because there're reported cases that 0E counts increased only after the scan (PM9A1 and other OEM disks which can not call Magician can use DiskGenius or other softwares that have bad block detection function)
0F counts are not related to this event, please do not be anxious: the 0F count can increase even if the NVMe controller command fails to execute, and this may be due to some irrelevant reasons
For example,- 0x2002(INVALID_FIELD: A reserved coded value or an unsupported value in a defined field)
Regardless of whether or not your SSDs are affected, it is recommended to use the "3-2-1 backup rule" to back up important data.
1: Create one primary backup and two copies of your data.
2: Save your backups to two different types of media.
1: Keep at least one backup file offsite.
--- Serial Number Decode ---
It is known that the beginning of S4 / S5 may also be reported 0E, so the data is for reference only.
Currently known bits of interpretation: for example, S6P7NG0R, S6 can be presumed to be the new controller version, P7 corresponds to 970 EVO PLUS 1TB, G corresponds to the South Korean production, R corresponds to 2021 production
Feel free to share your serial number, I will add them to the list if they're also affected
Add: According to the observation of a large number of PM9A1, the ninth digit of the serial number corresponds to the factory month (hexadecimal), such as S676NX0T7 factory year and month for 2022.07
Also applies to other models, such as my 980 PRO with Heatsink S6WRNS0RB corresponds to 2021.11 (11 in decimal is converted to hexadecimal is B)
The 8th and 9th bits of the S/N label of the Samsung SSD are used to indicate the production date.
The eighth bit indicates the year, 2008-Q, 09-S, 10-Z, 11-B, 12-C, 13-D, 14-F, 15-G, 16-H, 17-J, 18-K, 19-M, 20-N, 21-R, 22-T, 23-W.
The 9th digit indicates the month, 1 for January, 2 for February, 3 for March .... When it is greater than 9, it starts to be represented by a letter, A for October, B for November, C for December
The fourth bit corresponds to the capacity, such as S674 for 256G, S675 for 512G, S676 for 1024G, S677 for 2048G
The third and fourth digits of the serial number do not correspond to the same number/letter, e.g. 980 PRO 2TB corresponds to S69E, 980 PRO with Heatsink 2TB corresponds to S6WR
The sixth and seventh digits of the serial number correspond to the place of shipment, and the following letters are observed in the sixth digit.
Made in Korea: A C E G J S(0-3) W
Made in China: B F X (SA)
Made in Thailand: M Z
Made in Vietnam: L U
The seventh bit is usually 0, a few are 1-3, 850 series SA originated in China, which is suspected to be a special case (corresponding to EA originated in Korea), the exact meaning is unknown
The second digit is highly correlated with flash memory generation (the time of its appearance basically coincides with the flash memory replacement schedule), but there is still no evidence to prove that it refers to flash memory generation, and there are suspected counter-examples (e.g. 970 EVO PLUS that was shipped after August 2021 switched back to serial numbers that begin with S4, 980 PRO was mixed with S5 and S6), still need more infos
PS: Considering that the 990 PRO serial number still starts with S6 but uses V7 NAND, we can basically rule out the possibility that the second digit is flash memory generation. |
