Re: Trouble with Microsoft Word. Long

Well unless the Win32API function ReadFile detects it as an outlook file and does some additional checking, it failed to read about 3 512 byte sectors out of the file when I wrote a progam to do so utilising ReadFile. So from that I concluded that it was disk corruption which the disk error checking didn't detect. Again outlook was happy to read the file after I read it back including the bad sectors, it knew the the data wasn't consistant but only failed to display the corrupted email. It wouldn't load the file when CRC errors occurred during reading the file but was happy to load the inconsistant file with no CRC errors. On this basis I don't have much faith in the Win2k disk check.

it to recover all outlook thought was correct. Needless to say I was rather concerned that the full disk error checking routine hadn't found any errors. The drive was replaced very shortly afterwards.


	I *think* that it was not actually the drive, but a CRC check
within the data structure of Outlook's proprietary mail file format.  As
a result, the disk scan could not find it -- because it was not a
corrupted disk sector, but rather a corrupted data block within
Outlook's file format -- which is overlaid over the sectors of the
Windows filesystem.

	Still -- the newer disk was probably a good idea.

	I don't know whether the corruption came from a problem in
Outlook, an attempted virus infection, or what.  (And, since I don't
(and *won't*) use Windows systems for e-mail, I don't have any such
files to analyze.

	Good Luck,
