常见问题解答

IS917主控的ID 94 EB和2C 64 64 3C分别代表什么？

IS917主控的ID 94 EB和2C 64 64 3C是闪存颗粒的识别码（Flash ID）。94 EB通常对应某款1×1 nm工艺的闪存，而2C 64 64 3C是另一款闪存的ID。这些ID在数据恢复中用于确定闪存的类型、容量和通道配置，从而匹配正确的提取算法和布局参数，是Flash Extractor工具进行底层数据读取的关键依据。

IS917的Xor 3c58_256和Xor 3c58_512有什么区别？

Xor 3c58_256和Xor 3c58_512是IS917主控的XOR（异或）算法变体，区别在于XOR操作的数据块大小。256表示按256字节块进行异或处理，512则按512字节块处理。这种差异源于闪存页大小或ECC配置不同。在数据恢复时，必须选择正确的XOR值，否则读取的数据会因解扰错误而无法重组，导致恢复失败。

IS917的MBR和FAT32损坏时如何手动重建？

当IS917设备的MBR和FAT32损坏时，手动重建需先用Flash Extractor提取完整的原始镜像，然后分析分区表起始位置和FAT表结构。由于FAT32的根目录和簇链信息可能残留，可通过搜索文件签名（如JPEG头）定位数据区，再根据FAT表项重建目录和文件分配。建议使用工具中的Assembler功能，按Block Number和Bank Space参数重新组织数据，最后修复引导扇区。
