6. TROUBLESHOOTING AND FAQ'S
How can I determine the exact capacity of the hard disk?
?
Open the Control Panel, followed by the "Administrative Tools" folder. All system programs of this folder
!
are displayed. Open Computer Management. Computer Management is a general program that inclu-
des an area with the name "Storage" Click on the + symbol in front of this area and select the suboption
"Disk Management". On the right of the window, all the existing data media are displayed. The list also
displays the total size and the partitions on each medium, along with the size of each partition.
My applications seem to run very slowly on the USB 1.1 port.
?
!
If you connect your hard disk to you computer via a USB 1.1 interface, then the data transfer rate will be
approx. 1MB per second. TARGA does not recommend installing applications on a hard disk when using
the USB 1.1 interface. However, the USB 1.1 still works fine for saving data for most of the applications.
A message appears saying that I have a high-speed device connected to a port only supporting a
?
low data transfer rate.
!
This is normal. Windows XP informs you that you have a USB 2.0-compatible device connected to a
USB port only supporting the USB 1.1 standard, and will therefore not benefit from the high data transfer
rates of USB 2.0.
The data transfer rate of my USB 2.0 adapter card seems to be too slow.
?
The TARGA hard disk drives feature the highest data transfer rate supported by the host controller (max.
!
480Mit/s). If you are concerned about your hard disk throughput please make sure that you are using
the latest drivers for your adapter card and that they work properly.
The application programs I have installed on my hard disk fail to execute.

Byte A storage unit on a hard disk (1 Byte = 8 bit).
Boot Drive The drive used to load the operating system in order to start your computer.
Capacity The amount of information, e.g. measured in Bytes, that can be stored on a hard disk. It is also known
as Storage Capacity.
Connector A connector or socket on the motherboard, controller card or housing to which peripheral devices can
be connected.
Data Transfer Rate The speed at which data can be transferred to and/or from a hard disk (for example).
Device Driver Software that enables a PC to communicate with peripheral devices such as hard drives and/or CD-
ROM drives. Each device model requires a different driver. Device drivers are stored on the computer's
hard disk. When booting the computer or connecting a device to it, the corresponding driver is loaded
into the memory.
External Hard Disk An external peripheral device that includes a hard disk mechanism and can be connected to a computer
via a FireWire or USB interface.
FAT32 A file system that manages computer files. This is the default file system in Windows 98SE and Me but
is also supported by Windows 2000 and XP. One single file is limited to a maximum size of 4GB.
FDISK A Windows 98 and ME software tool used to partition a hard disk.
Formatting Formatting a hard disk will erase any data saved on it and create a file system for saving and retrieving
files. On a Macintosh, the high-level formatting is often called as Initializing. A low-level format will divide
a hard disk into sectors.
GB (Gigabyte) One Gigabyte is equivalent to 1 billion Byte.
Hard Disk Drive An electromechanical device for storing and retrieving information. It consists of one or more rotating
disks that records, saves and reads the data magnetically.
Hot-Swap This feature enables the connection or removal of external devices while the computer and the device
are turned on. External hard disk drives such as the TARGA DataBox II 250 support Hot-Swap.
KB (Kilobyte) One Kilobyte is equivalent to 1,024 Byte.
Mb (Megabit) When referring to storage of information, one Megabit is equivalent to one million bit.
MB (Megabyte) One Megabyte is equivalent to 1 million Byte.
Mbit/s (Megabit per second) When referring to data transfer rates this designates 1 million bit per second.
Media Describes a medium used for storing data, such as a disc or a memory stick. The term Media is also
often used as a synonym for hard disk. However, it is possible for more than one medium to exist in one
drive, or that one medium can be shared between several drives.
NTFS The primary file system used by the Windows 2000 and Windows XP operating systems that handles
the files on your computer. It supports large hard disks up to 2TB capacity.
Operating System Software that enables the user and the programs installed on the computer to communicate with the dif-
ferent hardware components like the hard disk or the CPU.
Partition The possibility to divide the hard disk into logical portions so that the operating system treats each parti-
tion as a separate hard disk. Each partition will be designated by its own drive letter.
ScanDisk A Windows 98SE and Me system tool that finds and corrects errors in the hard disk's file system.
TB (Terabyte) One Terabyte is equivalent to 1 trillion Byte.
USB "Universal Serial Bus", a standard for connecting external devices to your computer.
