For those who have seen this on
local drives, here are some items I'd suggest you do.
If you have an Intel chipset motherboard, get and install the latest INF drivers for the chipset. Errors with IDE, SATA, USB, and Firewire have been corrected in various releases. This link will get you close, it is for an 865 chipset though:

Every Service Pack addresses problems found since the last service pack or release. There are all kinds of hotfixes that are then tested and released in a SP. If you look, lots of these deal with data corruption under this or that circumstance. Untoward behavior of certain hardware combinations.
If you are not current, you can't be sure you are not seeing a correctable error.
If you are current, you still aren't 100%, but a darn site better than not patched.
Finally, if you haven't looked at your computer maker's site (or motherboard site) to see if there is an updated BIOS for your system, do so. Especially with new motherboards, you see update after update to correct oddities in things like IDE, SATA, etc. Again, without this, who knows?
Because as Jim says, "It could be lots of things". Take care of the others.
