我使用 GParted 将外部 USB 硬盘驱动器划分为两个分区。两者都是格式为 FAT32 的主分区,大小相同 (500 GB)。这是的输出file -s
:
/dev/sdb1: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "mkfs.fat", sectors/cluster 64, reserved sectors 64, Media descriptor 0xf8, sectors/track 63, heads 255, hidden sectors 2048, sectors 976760832 (volumes > 32 MB), FAT (32 bit), sectors/FAT 119232, reserved 0x3, serial number 0x99034dfb, label: "TOSHIBA1 "
/dev/sdb2: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "mkfs.fat", sectors/cluster 64, reserved sectors 64, Media descriptor 0xf8, sectors/track 63, heads 255, hidden sectors 976762880, sectors 976760832 (volumes > 32 MB), FAT (32 bit), sectors/FAT 119232, reserved 0x1, serial number 0x96cbe274, label: "TOSHIBA2 "
在/dev/sdb2
,什么是hidden sectors
,为什么它大于sectors
?差值是 2048,恰好是hidden sectors
for的值/dev/sdb1
。这是巧合吗?GParted 或file
命令错误?更重要的是,有什么需要担心的吗?
