[VFATLIB] Never touch the file system if not in interactive or RW mode.
It's critical not to perform any write on a volume without an exclusive lock on it.
That lock is only acquired if ChkDsk is started in RW mode.
Also added an assert in write routine, to make sure that when we're about to perform
a write operation, we're really allowed to do so.

This will avoid volume corruptions when a simple "chkdsk" is issued from cmd.
To put it simple: check will really check now, and won't attempt any repair.

3 years ago[NTFS] - Commit early results of a small restructuring effort:

[NTFS] - Commit early results of a small restructuring effort:
-Add a new member to the NTFS_ATTR_CONTEXT struct, a LARGE_MCB. This allows an attribute context to describe the cluster mapping of a non-resident file while allowing that mapping to change dynamically, without the context itself needing to be resized. This fixes problems which sometimes arose from resizing files.
-Remove hacky code from NtfsWriteFile() for dealing with "stale" contexts. This fixes that issue.
-Update SetDataAttributeLength(), PrepareAttributeContext(), ReleaseAttributeContext(), FreeClusters(), and AddRun() for the new member.
-Update ReadAttribute() and WriteAttribute() to work with the changed structure. A very-soon-to-come commit will overhaul these functions so they'll operate directly on the LARGE_MCB, instead of converting to and from a packed list of data runs. (Sparse files are broken until then.)
-Rename "RunBufferOffset" to "RunBufferSize" in several places where appropriate.
-Fix, improve, and add some comments.

[NTFS] Add support for creating new MFT entries:

+NtfsCreateFileRecord() - Creates a new file record and saves it to the MFT.
+AddNewMftEntry() - Adds a file record to the MFT.
NtfsCreateFile() - Modified to create a file record on a file-creation request (file creation is still unsupported; the created file needs to be added to the parent's directory index).
+SetFileRecordEnd() - Establishes a new file record size
UpdateFileRecord() - Improved documentation
InternalSetResidentAttributeLength() - Updated to use SetFileRecordEnd().

*ConvertLargeMCBToDataRuns() - Use MS portable type, ULONG, for variable i.

*ConvertDataRunsToLargeMCB(), AddRun() - Avoid code duplication by using ExRaiseStatus() in try block, and return accurate status via _SEH2_GetExceptionCode().
