Sorry, but this is rubbish. Extended Attributes are referenced by their 
relative position in EA_DATA._SF from the file's directory entry, and
point back from EA_DATA._SF to the name of the file.

You can even (under DOS) turn EA_DATA._SF into a normal (non-hidden,
non-system) file, copy it around or defrag the disk, set the +h and +s
attributes again, and then boot to OS/2 and everything works fine.
Believe me, I did that several times.

All my EA corruptions resulted from using native OS/2 programs, but I
never messed up my EAs from DOS.
