我的英特尔 SSD 520 系列 240GB SSDSC2BW240A3L SSD特色SandForce SF-2281VB1-SDC控制器突然死机，BIOS 中没有显示。据推测，它的固件已因我的笔记本电脑硬件故障而损坏。它实际上是一个损坏的 SSD，我正在尝试自己恢复数据。
SSD 允许通过所谓的“安全模式”（使用硬件跳线开机）将固件直接写入 SandForce NAND 控制器身体上放）。
该过程似乎与制造商认为的刷新固件的“正常”方式（例如 ATA）有很大不同hdparm --fwdownload。相反，控制器芯片的“安全模式”会使 SSD 显示为一个SandForce{200026BB} (20DABBR0)带有 32kiB 零的小块设备（），可能允许将固件写入其中）。
注意：无法使用制造商官方软件刷新固件，因为在没有物理安全模式跳线因此不会被更新程序识别。
使用“安全模式”刷新英特尔 SSD 520 系列 SSD 驱动器的最新固件映像时，数据是否保持完整？
FWIW，10 年前有人问过类似的问题，但我想知道是否也是如此，具体来说当使用控制芯片的“安全模式”时。
