Nt Volume Direct Access error

I upgraded the hard drive of two computers.
Both are Hp Vectra 5 series pcs.
After having copied the data over succesfully using Power Quest Drive Copy, when booting I received an error in the blue screen Just below the three dots (...) that display just before you get the login prompt in NT 4.o
The computers seem to be working correctly but i'm worried about the error.
Any Info will be greatly appreciated.
