why does windows only report 149-GB when the bios reports
160-GB? Will this cause any problems after formating with
data loss?

Hi henry
It's really not an issue at all. It's a question that has been answered and
over-complicated by many posts in this and other NGs.
Open My Computer
right click on the SATA drive and select properties.
look at the capacity values for the SATA drive
It will read 160,0xx,xxx,xxx bytes (where the 'x' will be a number 1 to 9)
beside that will be the value 149Gb
The computer translates the value of 160,000,000,000(and more) divided by
1024 divided by 1024 divided by 1024 to get 149 Gigabytes.
This is because it is using 1 Gigabyte = 1024 Megabytes = (1024 times 1024)
Kilobytes = (1024 times 1024 times 1024) bytes
Meanwhile
The BIOS is reading the manufacturer's designation of the drive. The 160Gb
they refer to uses a decimal notation of 1 Gigabyte = 160,000,000,000 bytes
Neither value is 'wrong'... they are equivalent.
Feel free to look through the many threads that are now multiplying across
this NG for further enlightment and confusion in equal measures.
Hope that helps
Pete
