Acomdata External HARD DRIVE USB 2.0 User Manual page 102

Q: Can I connect the Drive to a USB expansion card?
A: Yes, but you may need to update the software/firmware for the card. We rec-
ommend you check with the card's manufacturer for the latest updates.
Q: Is the Drive compatible with Win 95, 98 (First Edition) or Windows NT?
A: No.
Q: Why doesn't the Drive have a fan?
A: All hard drives generate some heat during normal operation, which is why hard
drives often have big, noisy fans. The AcomData Drive was engineered to be more
efficient and to generate so little heat that it does not need a fan, allowing us to
make the drive as compact and lightweight—and quiet—as possible.
Q: Why is the capacity of my Drive, as shown in Windows or Mac OS, lower
than the Drive's stated capacity?
A: The difference is mostly due to the way Windows and Mac operating systems
measure hard disk capacity, as compared to the method used by hard drive
manufacturers. Hard drive manufacturers have always used the decimal (base
10) method, where 1GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 bytes.
Windows and Mac operating systems use the binary (base 2) method, where 1GB
= 1,024 MB = 1,048,576 KB = 1,073,741,824 bytes.
For example: 120 GB (decimal) = 111.8 GB (binary). How did we get that num-
ber? Using the decimal method, 120 GB = 120,000,000,000 bytes. To convert
that to binary we divide 120,000,000,000 by 1,073,741,824, which equals 111.8.
Therefore, a 120 GB hard drive partition will mount as approximately a 111.8 GB
