What is Compact Flash?

CompactFlash is the world’s smallest removable mass storage device. First introduced in 1994 by SanDisk Corporation, CF ^TM cards weigh a half ounce and are the size of a matchbook. They provide complete PCMCIA-ATA functionality and compatibility. Compact Flash is a small, removable mass storage commonly used in digital cameras.

Where will CompactFlash be used?
Several leading consumer electronics companies, including the CFA’s roster of founding members, are designing CF technology into next-generation products being developed for mass markets. The CFA expects CF technology will be widely used in such products as portable and desktop computers, digital cameras, handheld data collection scanners, cellular phones, PCS phones, PDAs, handy terminals, personal communicators, advanced two-way pagers, audio recorders, monitoring devices and set-top boxes. CF technology offers all of these applications new and expanded functionality while enabling smaller and lighter designs.

What is the difference between Type I and Type II?
Type I is 3.3mm thick, while Type II is 5mm thick. A CF Type II device will not fit in a Type I slot.

How do I format my Compact Flash drive?
Formatting a Compact Flash drive can be accomplished several ways. The most common method of formatting a Compact Flash drive is within the device in which the Compact Flash drive will be used. This will ensure a device compatible format and the best overall performance.

How do I interface the CF drive with my PC or Mac?
Compact Flash drives are connected to desktop/laptops computers through flash memory card readers. A typical card reader will contain multiple flash memory slots to accommodate the different types of memory. The card readers are most commonly attached to the computer via a USB or IEEE 1394 (FireWire) interface cable.

Do I need drivers for my OS?
Compact Flash drives do not require drivers. However, when the drive is attached through a card reader, the proper drivers for the card reader must be installed before the drive can be accessed.

Can I use this in my PDA? Does this drive require drivers?
The Compact Flash drive can be used in any PDA that will support Compact Flash Type II drives with high capacity. This is not a supported hardware environment.

While many PDA operating systems do not require drivers, some of the older operating systems, such as Windows CE, will require a driver before the drive can be accessed.

Can I install an OS onto this drive?
Depending on the operating system in use, it may be possible to install an OS onto the Compact Flash drive. Since this is not the intended purpose of the drive, the performance may be less than desired and no support will be provided.

What is the speed of my Compact Flash card?
Solid state CF memory cards are differentiated by a speed number:

Compact Flash Speeds
Speed	Kbytes/s	Mbytes/s
1	150	0.15
4	600	0.6
12	1800	1.8
24	3600	3.6
40	6000	6
60	9000	9
80	12000	12

What is the difference between FAT16 and FAT32, why do cards greater than 2GB require FAT32?
File Allocation Tables (FAT) are like a table of contents to your data. Prior to Windows 98, 16-bit FATs limited partitions to 2.1 Gbytes. The newer 32-bit FAT is capable of huge partitions up to two Tbytes (terabytes). Many digital cameras only support 16-bit FAT (FAT), newer cameras and high-end professional cameras usually support 32-bit FAT (FAT32). Check your camera’s manual or support information to determine if your camera supports FAT32 (memory larger than 2.1Gbytes).

Cables for Ultra ATA/66 to Ultra ATA/133 Hard Drives

DATARECOVERYUNION.COM14 years ago4 years ago03 mins

This FAQ applies to all Seagate, Maxtor, Quantum ATA 66, ATA 100, and ATA 133 drives.

The faster timing requirements of Ultra ATA/66 and above require the use of an 80-conductor cable. This is necessary for proper operation of UDMA modes 3 and greater. The 80-conductor cable is used with the same connector configuration as the standard 40-conductor cable. The 40 additional conductors are used as ground paths and are all connected to the 7 original ground conductors. These additional ground conductors serve to improve the overall signal quality (signal-to-noise ratio) of the ATA cable. 80-conductor Ultra ATA cables are also limited to a maximum cable length of 18 inches.

If the drive was purchased in a retail kit and not as a “bare” drive, the kit includes an Ultra ATA cable as described here. If not Ultra ATA cables can be purchased from your system vendor or reseller and are fully backward compatible for operation on all standard/legacy ATA devices and hosts. However, these cables will typically utilize the cable select (CS) configuration on ATA drives for defining a master or slave device (drive 0 or drive 1). The drive placement convention used on an 80-conductor cable is also different from the previous generation of cable select type cables. The 80-conductor Ultra ATA cables require the master drive (drive 0) to be installed at the end of the cable and the slave drive (drive 1) to be installed on the middle connector.

The connectors on 80-conductor cables are also color-coded to help ensure proper drive placement and attachment to the host (system). Typical color-coding is as follows: blue for attachment to the host (system), black is for device 0 (master), and gray is for device 1 (slave).

Special Requirements to use an Ultra DMA Hard Drive

DATARECOVERYUNION.COM14 years ago11 months ago06 mins

Are there any special system or software requirements to use an Ultra DMA 33/66/100/133 ATA hard drive? Yes as follows:

To utilize the Ultra DMA (UDMA) capability of a hard drive, the system that the drive is being installed into must contain the appropriate hardware chipset and have the necessary software drivers installed. The system’s motherboard must be designed with a core logic chipset that provides the desired UDMA support. Also, it is the motherboard or system manufacturer’s responsibility to provide any additional software drivers that may be necessary to implement UDMA (Ultra ATA) operation.
Pentium II and newer motherboards and systems will typically contain some level of hardware support for UDMA operation (this could be UDMA 33, 66, 100, or 133 depending on the age of your system). It will be necessary to consult the system or motherboard manufacturer’s documentation to determine the level of UDMA supported by your particular hardware. For example if you install a new Maxtor hard drive capable of Ultra DMA/100 (UDMA mode 5), but your system is only capable of supporting Ultra DMA/33 (UDMA mode 2), you will only be able to achieve the Ultra DMA/33 performance. In this case you may want to consider upgrading your motherboard or purchasing an add-on PCI adapter, such as Maxtor’s Ultra ATA card, that is capable of supporting the latest Ultra DMA transfers. This is an inexpensive alternative to replacing your entire system or motherboard.

All Maxtor UDMA drives are fully backward compatible to earlier, non-UDMA systems. Just keep in mind that the transfer rate (performance) of your drive will be limited by the system’s capabilities and not necessarily by the hard drive.

Windows 95 (all versions), Windows 98 (all versions), and Windows NT 4.0 all have limited “bundled” driver support for UDMA operation. If you are attempting to use a hard drive capable of UDMA/66 or greater with one of these operating systems, you will more than likely need to obtain updated drivers for your system. It is best to always check with your system or motherboard manufacturer for UDMA driver requirements and availability. In some cases updated drivers may be available directly from Microsoft or from Intel if an Intel chipset is being used by your motherboard. Maxtor Corp. does not provide software drivers for UDMA operation since any required drivers are specific to the chipset and not the hard drive.
Windows ME, Windows 2000, and Windows XP all have expanded “bundled” driver support for UDMA operation and may already contain the necessary driver support. Updated drivers may or may not be required depending on your motherboard’s chipset. Once again, it is always best to check with the system or motherboard manufacturer for driver requirements. A good resource for Ultra ATA drivers for systems with Intel based chipsets is at the following site: support.intel.com/support/chipsets/storagedrivers/ultraATA.
For systems and hard drives which have all of the prerequisites for UDMA mode 3 and greater (UDMA/66 and faster), a special 80 conductor, 40-pin interface Ultra ATA interface cable is required. The 80 conductor cable reduces cross talk and improves signal integrity by providing additional ground lines between the 40-pin ATA signal and ground lines. Due to the higher transfer rates and shorter cycle times of UDMA data transfers, this cable is required for UDMA/66, UDMA/100, and UDMA/133 operation. It is also highly recommended for UDMA/33 operation as well to help prevent any possible noise related issues.

All Maxtor Retail Kits that contain a UDMA/66 or greater hard drive will also include the 80-conductor Ultra ATA interface cable. This Ultra ATA Interface Cable conforms to the ANSI Specifications.

Computer Cables Overview

DATARECOVERYUNION.COM14 years ago4 years ago06 mins

1. External Drives Cables:
USB, FireWire 400, FireWire 800, eSATA, Powered eSATA

a) USB Cable
USB is the most common connection type for external devices, whether external hard drive, thumb drives, flash drives, printers, cameras, all kinds of other devices. It is extremely easy to use. Whether the computer is powered on or powered off, simply connect the cable to your device and it should be ready to be used less than 30 seconds later (depending on your computer’s speed).

The USB cable has two ends – one to connect into the drive, and one to connect into the computer. Sometimes these ports are found both on the front and the rear of your computer.

b) FireWire 400 and 800 Cable
FireWire is a similar connection to USB, in that it is plug-and-play. Simply connect your device to the computer and it will usually be ready to be used within 30 seconds. FireWire is much more common in Mac computers than in Windows computers.

FireWire comes in two speeds at this time – FireWire 400 and FireWire 800. FireWire 400 (also known as 1394a) usually gives performance similar to USB. FireWire 800 (1394b) is significantly faster, giving performance similar to an internal Serial ATA drive, but is less common than FireWire 400, and is almost exclusively available in Mac computers.

c) eSATA Cable
eSATA (external Serial ATA) is a high-performance interface most commonly found in Windows PCs, but is fairly rare.

The eSATA cable’s connector and the port look similar to that of a normal Serial ATA connector and port, but they are not intercompatible due to small physical differences.

d) Powered eSATA Cable
Powered eSATA provides high performance like eSATA, but like USB 2.0 it also provides electrical power to operate a drive without needing to use a separate power cable for the drive. This interface is even more rare than eSATA.

2. Internal Drives Cables:
Serial ATA (SATA), (Parallel) ATA (PATA)

a) Serial ATA (SATA) Cable
Serial ATA is the most common connection for internal drives in modern PCs and Macs (including all G5s). There can be multiple SATA ports on any one motherboard or controller card. One cable connects one hard drive to one port on the motherboard (as opposed to Parallel ATA).

SATA drives include a small power adapter that plugs in to the normal power cable inside your PC or Mac so that it will fit the SATA drive.

b) (Parallel) ATA Cable
ATA is a very common connection for internal drives in older PCs and older desktop Macs (before G5), and for devices like CD and DVD drives in modern PCs and Macs. It is a connector about 2 inches (5 cm) wide and has 40 small gold pins that will fit into the corresponding 40 small holes on its corresponding connector. There can be two or four ATA ports on any one motherboard. One cable can connect to two devices at the same time.

Blue connector – always connects to the motherboard.
Grey (middle) connector – is used for slave devices on the cable.
Black connector – is used for master device connection.

Note: An ATA hard drive will also have different jumper settings depending on whether it is connected as slave or master. An ATA hard drive that is connected to the same cable as a CD or DVD drive must be connected to the master position, with the CD or DVD drive in the slave position.

Solutions for Seagate Barracuda 7200.11 HDD Common Errors(Part I)

DATARECOVERYUNION.COM14 years ago4 years ago02 mins

There are two common errors on Seagate Barracuda 7200.11 HDDs (caused by bugs on firmware):

0 LBA error: it happens when your BIOS can recognize your HDD at POST moment, but as an 0MB drive.
BSY error: it happens when your HDD enter on a halt state, or Busy state. In this condition, your HDD will not be recognized by BIOS at POST moment.

Solutions: You’ll need: TTL adapter

Attention: This guide might not be to every case. No responsible for any damage or data loss it can happen.

TX and RX connections from a SATA Seagate 3.5″:

Photo with the real drive:

Connect TX and RX ports with RS232 to TLL adapter, you’ll need something like jumpers in order to do that, or soldering directly to the PCB board. Connect GND and +5V to PC power supply, or similar. Keep in mind those are direct from Seagate sides, so you’ll need to connect in this way:

– From PC (TX) to >>> RX (on Seagate)
– From PC (RX) to >>> TX (on Seagate)

You can use RED wire (+5V) from PC power supply. Blacks are GNDs (yellow is +12V so don’t use it).

If you don’t want to mess with power supply, just use a CR2032 (3V) battery:
