I have seen random client-side disk IO errors when our virus scanner interfered with the sqlite library used in subversion 1.7, when massive log file activity triggered a bug (which is still not fixed) in the behavioural analysis module of the virus scanner.
Try to disable the virus scanner (at least for the .svn directory) or try a subversion 1.6 client which does not use sqlite. I can send you some detailed information and a test application if you are interested.
