這些信息記錄在:[HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices]鍵值下,內容大致為(從我的電腦裡導出的):附件1
這裡面重要的是這幾個:
"\\DosDevices\\R:"=hex:eb,f8,b2,92,00,7e,00,00,00,00,00,00
上面的R:表示盤符為R,後面的HEX值中分成兩個部分,第一部分是前4個HEX值,表示R分區所屬硬盤的序號,後面8個HEX表示R分區在這個硬盤的偏移起始位置,以字節為單位。對照上面的R,看一下R分區所屬的硬盤的0扇區:

圖中偏移為0x1B8~0x1BB,內容為HEX:EB F8 B2 92就是注冊表中記錄的R分區的硬盤序號。而從偏移0x1be~0x1ce中的第一組分區表可以看出,唯一的分區起始位置為0x3F,以扇區為單位,換成字節就是0x3F*0x200=0x7E00,如果用8字節的64位值表示,HEX就是00 7E 00 00 00 00 00 00 ,就是注冊表中記錄的鍵值的後半部分。
