Disk failure or not?

its the first time i see this in the even viewer... came 2 hours after i turned on my computer... rebooted and did not give it to me again ever since

An error was detected on device DeviceHarddisk1/D during a paging operation.

Notice the ''one'' in there..i have one harddrive thats it...... there for the main harddrive is known as zero in the disk manager.... 1.5 gb ram and 1.5gb paging file and 40 gbs free hard drive space..could this be a USB problem, becuase i think at that time i was copying big to my usb thank uDisk failure or not?
anyone?Disk failure or not?
Were you copying to a Flash Drive or a portable Hard-drive?But if it hasn't popped up again, then you should be fine, it's only when these sorts of errors start happening freqeuently (or more then once in a short period of time) that you should be worried.
flash drive... thanks, it happened once until now, which is when they came up around 5 times after each other but thats it...
