Value | Description |
---|---|
08h | FAT16 or FAT12 drive |
48h | FAT32, FAT16, or FAT12 drive. This value is supported on Windows 95 OEM Service Release 2 and later. |
Note: Because this call may be implemented in the device driver, the 48h form of this call may fail on FAT16 or FAT12 media. Therefore, applications making the 48h form of this call must fall back on the 08h form if the 48h call fails.
If the function is successful, clears the carry flag. Otherwise, sets the carry flag and sets the AX register to one of the following error values.
01h | The function is not supported. |
B1h | The volume is locked in the drive. |
B2h | The volume is not removable. |
B5h | The valid eject request has failed. |
If a given physical drive has more than one logical volume, all volumes must be unlocked by using Int 21h Function 440Dh Minor Code 48h (FAT32) before the drive will eject.
