It is possible that during the time that the file was deleted (removed from the MFT) some other application has overwritten a part of the file. Word's file structure in addition to the actual text and other elements of the document contains a large amount of formatting information. Any damage to the formatting data structure will most likely wreak havoc in the document and make it unreadable.
However there are several tricks that you might try, in order to at least save some part of the file:
If you were able to open the file in Word, but the info in the document is corrupted, try saving it in an alternate format. Sometimes, using a format such as RTF or TXT will cause some of Word’s codes to be stripped from the document, which often fixes the problem.
If you are unable to open the file with Word, it usually means that the whole Word file structure is lost. If this is the case, try opening the file with other application that supports Word files or open the file in a simple text editor (some enhanced version of Notepad like Notepad++ for example). Then scroll through the file to see whether you can find any raw text that you can salvage.
You may also be able to recover the text portion of a document using Word’s text converter. Click File > Open. When the Open dialog box appears, select the troublesome Word document. Then, choose Recover Text From Any File from the Files Of Type drop-down list and open the document. This is very similar to extracting the raw text as this will only allow you to recover ASCII text losing Word formatting and items such as graphics.
Word has a built-in function that sometimes allows it to repair the file. Click File > Open. When the Open dialog box appears, select the troublesome Word document but instead of clicking Open, click on the little arrow on the button and select Open and repair.
