Report "I have a lacie 750 gb external drive used for media storage. When using explorer to search the drive it freezes up, eventually becoming unrecognizable to the computer and becomes inaccessible until I turn it off and back on. If played directly from windows media it will work for a while but eventually becomes unresponsive again. I tried check the disc for problems under the properties tab, but it freezes too and says the disc cannot be checked while in use, even though all programs are closed"
