you can use ctl-L to refresh a vim edit screen... (if you're in insert 
mode, hit <ESC> first)...  beats quitting and starting over.

 do these errors always occur on /dev/hdc or random devices?  if always 
/dev/hdc, is that a CD/DVD or a HD ?      that OQO thing is some kinda 
VIA C7 or whatever?   you might try disabling DMA on the /dev/hdc, like...
    /sbin/hdparm -d0 /dev/hdc

[this would have to be put in a init file, maybe /etc/rc.d/rc.local ]
