I had that problem with a RAID once. you could even sync, but it was no
guarantee the data was on the disks. The RAID sub sytem reported 'all
written' and that was that. Except it wasn't. it was in the RAID system
buffers.
The 'Dirty' line in /proc/meminfo said the pages were still in
dirty state. A manual sync did clear them out.
