USB and FireWire hard drives are not affected by motherboard BIOS capacity limitations.

The FireWire 1394a, 1394b, USB 1.1, and USB 2.0 protocols natively support 48-Bit LBA (Logical Block Addressing). The 48-Bit LBA standard is for addressing support of hard drives larger than 137GB. There may be an Operating System limitation related to drives over 137GB.

All Mac Operating Systems later than 9.0 support 48-Bit LBA natively.
For Windows 2000, Service Pack 3 (or later) must be installed to add 48-Bit LBA support to Windows.
For Windows XP, Service Pack 1 (or later) must be installed to add 48-Bit LBA support for Windows.
These Operating System updates can be downloaded from Microsoft’s Website.

It is important to note that the reported capacity of a large drive may often appear as less than expected. Please remember that, depending on the particular utility used, the capacity of the hard drive can be reported in either decimal gigabytes (where 1 GB = 1,000,000,000 bytes) or in binary gigabytes (where 1 GB = 1,073,741,824 bytes). Highlighting your C: drive in Windows Explorer reports the drive capacity in binary gigabytes. For example, a WD2000BB hard drive’s capacity will be reported as approximately 186 binary gigabytes.

How does WD Sync encrypt your data?

DATARECOVERYUNION.COM15 years ago12 years ago11 mins

WD Sync password protects your synchronized data to ensure a high level security. All synchronized data is 128-bit encrypted (AES 128-bit encryption). This data cannot be accessed from outside the WD Sync program (the program must be run in order to access the data).

When run, WD Sync leaves absolutely no files behind, keeping your information secure, regardless of the system you’re using. You can use a public computer, a friend’s computer or a colleague’s computer without leaving behind any trace (cookies, temp & history files). With WD Sync, your personal files and Outlook/Outlook Express files remain on your Passport hard drive, and are not copied to the computers you visit.

Recommended Western Digital External Hard Drives

DATARECOVERYUNION.COM15 years ago1 year ago13 mins

The main purposes we need an external hard drive:

Expand your computer’s storage capacity;
Backup your data and share data between computers;
Easy to use. Most of the time, you just need to plug it into the computer and use it as an internal hard drive.

Desktop external hard drives are based on the 3.5-inch internal hard drives and laptop (or portable) external hard drives that are based on the 2.5-inch internal hard drives. Generally, external hard drives are connected to a computer using collectively these types of connections: USB 3.0, USB 2.0, FireWire 400, FireWire 800, and eSATA.

USB 2.0, USB 3.0, or FireWire – What is the recommended solution for data storage?

DATARECOVERYUNION.COM15 years ago4 years ago15 mins

1. What is USB 2.0?

USB 2.0 is the industry standard peripheral connection type for most x86 computers (Windows based). This specification is rated with maximum transfer rate of 480Mb/s (60MB/s). Sustained transfer rate of USB 2.0 depends on many factors including type of device in use, data being transferred, and speed of the computer system. A normal sustained data transfer rate for USB 2.0 ranges from 10-30 MB/s. Only burst data transfers can reach the 480Mb/s rate.

What are the benefits of USB 2.0?

USB 2.0 is “hot swappable,” eliminating the need to reboot or restart your computer when attaching a device.
There’s no need for terminators, memory addresses or ID numbers with USB devices.
Various sorts of devices can plug into a USB port: external hard drives, digital cameras, printers, Zip drives, SuperDisk drives, floppy drives, mice, keyboards, etc.

2. What is USB 3.0?

USB 3.0 is the replacement connection type for USB 2.0. This specification is rated with maximum transfer rate of 4Gb/s. Sustained transfer rate of USB 3.0 depends on many factors including type of device in use, data being transferred, and speed of the computer system. Sustained transfer rates can reach speeds of 3.2 Gbit/s.

What are the benefits of USB 3.0?

USB 3.0 is “hot swappable,” eliminating the need to reboot or restart your computer when attaching a device.
There’s no need for terminators, memory addresses or ID numbers with USB devices.
Various sorts of devices can plug into a USB port: external hard drives, digital cameras, printers, Zip drives, SuperDisk drives, floppy drives, mice, keyboards, etc.
USB 3.0 is backwards compatible with USB 2.0 ports, and USB 2.0 devices will work on a USB 3.0 port (both at USB 2.0 speeds)

3. What is FireWire?

FireWire is a high-performance connection standard for personal computers and consumer electronics. Originally developed for Apple computers, this connection has been implemented by x86 computers for some time now. FireWire can move large amounts of data between computers and peripheral devices at transfer rates of up to 400 Mb/s (50 MB/s). A new FireWire specification, FireWire 800 (or FireWire B) has entered the computer market with transfer rates of up to 800 Mb/s (100MB/s).

What are the benefits of FireWire?

FireWire is “hot swappable,” eliminating the need to reboot or restart your computer when attaching a device.
There is no need for terminators, memory addresses of ID numbers with FireWire devices.
Though USB 2.0 is rated at a higher throughput speed (480Mb/s related to FireWire’s 400Mb/s), FireWire delivers faster performance for sustained transfer rates on external hard drives. This is because FireWire has lower overhead (less instructions that the CPU has to interpret related to USB 2.0).

Which connection type is better? USB 2.0, USB 3.0 or FireWire?

If you plan on transferring large amounts of data often, then USB 3.0 would be the best connection type for you.
If you are doing Audio/Video or are on a Mac, than FireWire would be a good choice as many of these programs recommend FireWire over USB 2.0, and Apple currently does not support USB 3.0.
If you want the versatility of connecting the hard drive to many different computer systems quickly and easily, and transfer rates are not that important, then USB 2.0 would be the ideal because it is compatible with both PCs and Macs, and most computers today still have USB 2.0 ports.

Slow transfer rates from my USB 2.0 drive in Windows

DATARECOVERYUNION.COM15 years ago4 years ago01 mins

Problem:
A USB 2.0 drive appears to be performing slow data transfers.

Cause:
The drive may be running at USB 1.1 speeds.

Resolution:
Make sure that your system is configured to control the drive under the USB 2.0 specification.

Verify that you have a USB 2.0 host adapter or motherboard.
If the motherboard has embedded USB 2.0 ports, be sure the drive is connected to the USB 2.0 ports. Some motherboards have 1.1 ports in one area and 2.0 ports in another (they look the same).
Contact the motherboard or host adapter manufacturer to verify that the proper USB 2.0 controller drivers are loaded correctly.

Note: If you’ve checked with your motherboard or computer manufacturer, and have found that you only have USB 1.1 capability, you will need to install a USB 2.0 compliant PCI card (desktops), or a USB 2.0 PCMCIA card (laptops) in order to get USB 2.0 transfer rates.

Things you should know about external hard drives

DATARECOVERYUNION.COM15 years ago12 years ago01 mins

Depending on availability of parts during production, the internal hard drive in an external enclosure could be either SATA or EIDE.
They can only guarantee drive capacity. They cannot guarantee a particular internal hard drive model, data interface, rotational speed, or cache size in the external hard drive enclosure.
Dismantling any single-drive external enclosure to obtain this information will void the warranty of the hard drive.
Interface and cache of the hard drives inside the external enclosure does not affect the performance or the data transfer rate of the external hard drive unit.

Note: With the exception of eSATA and USB 3.0 external hard drives, USB 2.0 and Firewire 400/800 have yet to approach the transfer rates of the internal hard drives we use in our external enclosures.
