"Error -22" any help on a meaningless error with a single file

I do have a problem with a MS Word file. I can’t read or copy the file. Checking the permissions does not help. And the error message is not very useful.

<language=de>
Der Vorgang konnte nicht abgeschlossen werden, da ein unbekannter Fehler aufgetreten ist (Fehler -22).
</language>

In english the error does tell that the action could not be completed due to an unknown error (error -22)

Mac OS System Error Codes: 0 to -261 says:
"-22 unitEmptyErr Driver ref num specifies NIL handle in unit table"
see http://support.apple.com/kb/ht1618

What the **** is going on? I need this file and the backup did not complete because of the same error…

Macbook Pro, Mac OS X (10.6.6)

It's a disk error. Not good news. Boot from your installation disk and try to repair the drive in Disk Utility.

I've owned two SSD's, and one of them failed within 48 hours.

DiskUtil did repair some numbers and reports a valid disc now. The problem still exists. ****.

The fact that Disk Utility found errors proves that the SSD is malfunctioning. That should never happen with a journaled file system. Part of your file is probably stored at a location on the device that the controller has marked as bad and won't read from. Contact the vendor about a warranty claim.

This error code is rare, and typically misunderstood.

I can't disclose details of one way in which error -22 is reproducible with the HFS Plus file system, but your observation – that the problem persists after use of fsck_hfs (with Disk Utility) – is consistent with my assessment that fsck_hfs simply can not detect file system inconsistencies of this type.

Please note that error code -22 may occur with perfectly good hardware, so anyone in this situation should not rush to assume drive failure.

You should assume that there has been dataloss from the affected file; that it will be irreparable. If you can, restore from a backup of a point in time before the dataloss.
