我发现了一些奇怪的东西：
SMART Self-test log structure revision number 1

我让驱动器抛出大量 ATA 错误，数据不可读。我决定对它进行 RMA，所以我运行了hdparm安全擦除程序并shred在它上面扔了一个。由于这是一个小型（500GB 三星 EVO）固态硬盘，因此运行速度相对较快。我跑了另一个smartctl -t short......它“修复”了自己。
该驱动器仍然具有ATA Error Count: 207以下属性：

是什么导致 SMART 测试突然“修复”自身？我不认为驱动器可以再信任了？但是，我怀疑三星现在是否会对其进行 RMA，因为它没有通过测试...
