Back to my problem -- the code I sent on 3/1/2004 5:15 PM does not write - it fails after the
following code. I reviewed the documentation on Int 21h Function 7305h. It says that for writes,
SI can be 0001h - write to Other/unknown,
2001h - write FAT data,
4001h - write directory data, or
6001h - write Normal file data
I also tried setting reg.reg_ESI = 0x0001 to write Other/unknown.
No matter what I did, I still got the same old message:
Old Disk Utility Write Error
You are using a disk utility designed for an older version of MS-DOS or Windows...
I have kept WinME up to date with Microsoft. Do I need to restore some files? If so, which ones?
//------------------- Int 21h Function 7305h
//-----------------------------------------------------------
// SI contains read/write mode flags
// SI=0h for read and SI=1h for write
// CX must be equal to ffffh for
// int 21h's 7305h extension
// DS:BX -> base addr of the
// control block structure
// DL must contain the drive number
// (01h=A:, 02h=B: etc)
//-----------------------------------------------------------
reg.reg_ESI = 0x6001 ; // for write
reg.reg_ECX = -1 ;
reg.reg_EBX = (DWORD)(&ControlBlock);
reg.reg_EDX = drive+1;
reg.reg_EAX = 0x7305 ;
// 6 == VWIN32_DIOC_DOS_DRIVEINFO
fResult = DeviceIoControl ( hDevice, VWIN32_DIOC_DOS_DRIVEINFO,
&(reg), sizeof (reg),
&(reg), sizeof (reg),
&cb,0);
