Q: What type of computer do I need to use an AcomData pureDrive?
A: AcomData External Hard Drives work on most Windows PCs and Macintosh computers.

System Compatibility
• PC with a minimum 233 MHz Pentium, running Windows Vista, XP, 2000, Me, 98SE.
• Mac with G3 (or later) or Intel processor, running Mac OS 10.2 or later.

USB Connectivity:
Available USB 2.0 or USB 1.1 port. The port can be built-in to the computer, located on an expansion card, or on a USB hub. If using a USB 1.1 port, the Drive will operate at USB 1.1 speeds (up to 12 Mbps).

SATA Connectivity:
Available eSATA port and eSATA cable (cable not included).
Q: Can I use my Drive on two computers at the same time?
A: No. If you connect the Drive to two computers, you may damage the Drive and/or your computers.
Q: Do I have to format my Drive prior to using it?
A: No. All AcomData Drives come pre-formatted at the factory with the FAT32 file system, making them compatible with all supported Windows and Mac operating systems right out of the box.
Q: Can I re-format my AcomData Drive with another file system?
A: Yes, you can re-format your AcomData Drive with another file system, such as NTFS and Mac OS Extended (HFS+). The User's Guide contains complete formatting instructions.
Q: Can I format the Drive for use on multiple operating systems?
A: All AcomData Drives come pre-formatted at the factory with the FAT32 file system, making them compatible with all supported Windows and Mac operating systems right out of the box. For full instructions on how to re-format your Drive, including for use on multiple operating systems, refer to your User's Guide.
Q: What is the difference between FAT32 and NTFS?
A: FAT32 is an older and more compatible file system but it has certain limitations, such as file size (maximum 4 GB). NTFS is more secure and has fewer limitations. The NTFS file system can only be used on Windows 2000 and XP. If you plan to use your Drive on Windows 2000 and/or XP only, you may want to consider re-formatting the Drive using the NTFS files system. If you plan to use the Drive on a Mac OS only, and you do not need Windows compatibility, you may want to consider re-formatting the Drive using a Mac OS Extended file system. Refer to the User's Guide for instructions.
Q: What is the cache size on my AcomData pureDrive?
A: Models under 750 GB have 8MB buffers; models that are 750 GB or larger have 16MB buffers.
Q: Why doesn't the Drive need a fan?
A: All hard drives generate some heat during normal operation. Heat generation can be an issue with some hard drives, which is why hard drives often have big, noisy fans. The pureDrive 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: Do I need drivers for my AcomData External Hard Drive?
A: For USB 2.0 on Windows 98SE, you will need to install the USB 2.0 driver found on the supplied CD. All other supported operating systems have the necessary USB 2.0 drivers built in.
Q: What is USB 2.0?
A: USB (Universal Serial Bus) is an interface technology for the serial transmission of digital data. The original standard (USB 1) could transmit data at speeds of up to 12 Mbps (Megabits per second), which equals 1.5 MB/s (Megabytes per second). USB 2.0 has a maximum throughput of 480 Mbps (60 MB/s) – up to 40 times faster than USB 1. At that speed it is possible to transfer a full GB (Gigabyte) of data in less than 18 seconds.

USB is a master-slave, host-based technology, meaning USB devices need to be connected to a computer, either directly or indirectly via a USB hub in order to communicate with each other. The computer dictates data flow to, from, and between attached USB devices. While 480 Mbps is the maximum speed, data transfer rates will vary depending on a number of factors, including available CPU resources.

The USB standard supports up to 127 devices. Connecting more than one or two USB devices to a computer typically requires the use of one or more hubs, where each hub can accommodate several USB devices.

The maximum allowable length of a USB cable is 5 m (16.4 ft.). USB can supply on-bus power of up to 2.5 W. This means that many low-power-consumption devices, such as flash card readers do not need to be plugged into an electrical outlet because they can get sufficient power via the USB cable. More power-hungry devices, such as hard drives, still require a separate electrical connection for power.

USB is a plug-and-play and hot-swappable technology. You do not need to assign ID numbers, or connect terminators. On most operating system you do not need to install drivers because the necessary drivers are built into the operating system. Devices can be added and removed while the computer is running. Also, you can turn off the device when not needed, in order to conserve electricity.
Q: What is eSATA?
A: Parallel ATA (PATA) technology served computers well for about two decades. However, increasingly faster hard disk transfer rates have forced the ATA interface specification to be continuously updated in order to avoid becoming the limiting factor in disk I/O performance. SATA, a serial implementation of the ATA interface, was developed by the Serial ATA International Organization in response to this need. SATA's serial architecture can achieve faster data transfer rates than PATA by overcoming a number of electrical signaling constraints inherent in a parallel architecture. SATA can also be scaled to accommodate increasing storage capacities and higher performance demands. The external implementation of SATA is called 'eSATA'. eSATA cables and connectors are more robust than those used for internal SATA hard disks and can sustain greater wear and tear.
Q: Can I connect an AcomData Drive to a USB expansion card?
A: Yes, but you may need to update the software/firmware for the card. We recommend you check with the card’s manufacturer for the latest updates.
Q: If I have both USB 2.0 and eSATA on my computer, which one should I use?
A: If your computer is equipped with eSATA, we recommend using this interface. The maximum interface transfer rate of eSATA is about 3 times faster than that for USB 2.0. Depending on a number of factors, actual performance may not always be 3 times speedier, but you can expect to see significantly faster performance in day-to-day use. The advantage of USB 2.0 is it's ubiquity. You can take your Drive and connect it to almost any computer on the planet today, whereas eSATA is not yet as common.
Q: Can I use the USB 2.0 and eSATA connections at the same time?
A: No. You can only use one connection at a time.
Q: Can the Drive be placed in either the horizontal or the vertical position?
A: Yes. The Drive comes supplied with a slide-on stand for vertical placement, and adhesive rubber feet that you can affix to the case for horizontal placement.
Q: Why is the capacity of my drive as shown in Windows or Mac OS lower than the Drive’s actual stated capacity?
A: The difference is mostly due to the different way in which Windows and Mac operating systems typically measure hard drive 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.

Example: A hard drive with a capacity of 120 GB will show up on Windows and Mac with a capacity of, say, 111.8 GB. The actual number of available bytes is 120,044,335,923, which is just over 120 GB (decimal).

Hard drive manufacturers use the decimal method because it is simpler and less confusing to consumers who may not be familiar with the base 2 number system. Manufacturers of operating systems do not need to concern themselves with this issue, so they typically use the more traditional binary method.

As long as the drive displays the correct number of bytes (approximately), you are getting the drive’s full capacity. The reason we say that the number of bytes will be approximate is because operating systems reserve a small amount of disk space for their own purposes. The actual amount may vary depending on the operating system.
