Me? No. I managed to acquire a 2TB HDD before the price increased like crazy. It remains unused at the moment.

It isn't 10% of the speed.

SATA 3.0 Gbps uses 8b/10b encoding, leaving only 80% for the actual data transfer.

So,
80% x 3 Gbps = 2.4 Gbps
2.4 Gbps = 300 MBps

Or at least that is the theoretical number. Real world tests on SATA 3.0 Gbps with SATA 6.0 Gbps SSDs has revealed that the practical maximum speed is about 265 MBps.



And your HDD test is flawed because it is like driving your Ferrari from A to B to A in t time and then claim it takes t time to drive from A to B, which is what you actually did in your HDD test. The more appropriate test would be for your CPU to write to the HDD, which has seen numbers up to 150MB/s in typical HDD benchmark tests.

The moral of the story here, is unless you know what you are doing (like being intentionally misleading), use proper benchmarking software to benchmark.

tl;dr: It is 56.6% (practical) or 50% (theoretical) and not 10%.

You can estimate the time it will take to clone the HDD by "total capacity / average speed". For a 2TB HDD with an average read/write speed of 100MB/s, it will take 5 to 6 hours.

You can test the file integrity with a DOS command line tool like 'md5sum' or 'sha1sum'.

The md5sum tool in particular will generate a 32 character hash of any given file(s). So you can run the tool on the file in both computers and then compare the resulting hashes. If the hashes match, then the files are identical and your colour problem is likely the result of some other problem.

Here are some md5sum download links:

http://fossies.org/windows/misc/md5sum-w32.zip/ <- I like this one best
http://etree.org/md5com.html <- An alternate option
http://www.pc-tools.net/win32/md5sums/ <- Has a 'pretty' output. I don't like it, but you might.

Why is that?

You could try unplugging all the devices that you don't need, leaving only the 1TB to test and a DVD drive to install Windows with. That may test for both power and motherboard problem. If Windows is successfully installed, then it is likely to be a power problem. If it still can't be recognised, then it is likely to be a motherboard problem. Also try testing with different cables, as some of them may be faulty or clogged with dust.
