No thats not right either. I oversimplified and didn't catch it until your statement.
So what you really have to do then is take 1GB=1,000,000,000bytes according to manufacturer. So then take 160 times that to give you 160,000,000,000bytes. Then divide by 1024 to get it in KB, then 1024 to get MB, then 1024 one final time to give you GB. That gives 149.0116119384765625 GB. He is seeing 150, its correct.
Further Proof:
Those are 400Gigs and a 250Gigs.
Lets look at the math and see if Windows and the drives are showing the correct capacity:
1GB=1,000,000,000bytes starting point.
400,000,000,000bytes * 1kilobyte/1024bytes * 1megabyte/1024kilobytes * 1gigabyte/1024megabytes = 372.529GB
Windows Says: 30 + 100 + 242.61 = 372.61GB
1GB=1,000,000,000bytes starting point.
250,000,000,000bytes * 1kilobyte/1024bytes * 1megabyte/1024kilobytes * 1gigabyte/1024megabytes = 232.83GB
Windows Says: 4 + 228.88 = 232.88GB
