I search directly in source. Here what I found:
'aio' means asynchronous IO. It's throw when InnoDB checks results for
messages sended to Windows to do overlapped IO. Switching to MSDN :
error 995 The I/O operation has been aborted because of either a
thread exit or an application request. ERROR_OPERATION_ABORTED

Can you tell us, what were Mysql and Windows (and your SAN if any)
doing at the error moment ?
Are InnoDB tablespaces on USB devices ?
