Operating system software.

Due to operating system limitations, DOS cannot access the full capacity of drives greater than 8.4GB. The Microsoft Windows 95 operating system or equivalent (full installation), NOT a Windows 95 upgrade from DOS (Windows 3.1 or 3.11), is required to obtain the full capacity of any hard drive larger than 8.4GB.

System BIOS dated prior to September 1997 does not support drives greater than 8.4GB. Most older system BIOS's have a drive capacity limitation. Such limitations may include 528MB, 2.1GB, 4.2GB, and 8.4GB. The proper solution for a BIOS limitation is to contact your system manufacturer for assistance.

To obtain the full capacity of a drive larger than 8.4GB, you may try following solutions such as:

• Upgrade the BIOS
• Install a BIOS enhancer card
• Use the disk manager installation software

Please also check the "32GB BIOS Limitations" below for additional BIOS information.

To allow computer systems access all the data on drives larger than 137GBs, the T13 AT Attachment standards committee developed 48-bit addressing. 48-bit addressing increases the maximum addressable space to 144,115,188,075,855,872 bytes (144 Petabytes).

Computer systems manufactured before development of the 48-bit address method do not natively support drives larger than 137GB (but can, if upgraded as described below).

If you have recently purchased your computer system, we advise you to check with your manufacturer to see if your system has native support for 48-bit addressing before pursuing one of the workarounds listed below. If you have already installed your drive and the capacity lists as 137,438,953,472 bytes (137GB or 128GB), you will need to follow one of the workarounds below to make use of the remaining space.

1. Windows 2000/XP: Existing installation

Windows XP Service Pack 1 (SP1) or later and Windows 2000 Service Pack 3 (SP3) or later both add 48-bit addressing support to the operating system. This support will allow access to drives larger than 137GB (128GB). Once the OS is installed (to a partition smaller than 137GB), download and install the latest SP for your operating system. After installing the SP you will be able to partition the remaining space into a new partition.

If you are adding a secondary drive that is larger than 137GB (128GB) to Windows 2000/XP, be sure you download and install the latest SP prior to connecting the drive. This will ensure proper support is available once the drive is detected. Once connected, you should be able to partition the drive to the maximum capacity.

See the following Microsoft Knowledge Base articles for more information:

Windows XP (article 303013):

http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b303013

Windows 2000 (article 305098):

http://support.microsoft.com/default.aspx?scid=kb;en-us;305098

2. Windows 2000/XP: Installation

In order for Windows 2000 and Windows XP to detect the full capacity of a drive larger than 137GB during installation, the operating system CD will need the correct service pack integrated (see above for correct service pack) into the CD. To obtain a Microsoft Windows operating system CD with the latest service pack integrated into the CD, you will need to contact Microsoft (if the CD was purchased separate from the system) or your system manufacturer (if the OS came preinstalled).

3. Utility to enable to 48-bit addressing

48bitlba.com is site dedicated to assisting with the transition from the older 28-bit addressing to the newer 48-bit addressing. They provide a utility called ¡¥EnableBigLBA Tool' (as well as other resources) that will test the operating system for support and enable it if possible. The utility is supported by 48bitlba.com and can be downloaded from their site at the following URL:

http://www.48bitlba.com/enablebiglbatool.htm

4. Windows 95sr2/98/Me/NT: Add in a new ATA controller card and driver with 48-bit addressing support

These operating systems do not natively support drives larger than 137GB (48-bit addressing). The only way to add support would be to connect the drive to a controller card whose drivers support 48-bit addressing.

The VIA 4-in-1 drivers are reported to have similar functionality (for VIA chipsets).

In most cases, UDMA mode on hard drive will only activate when the drive is installed in a system with full UDMA capability, i.e., a mother board or interface card with the UDMA chips and the associated UDMA software drivers, hard drives are Ultra DMA 66 (UDMA Mode 4) compatible. For UDMA 66/100 data transfer rate, a UDMA 80-conductor cable is required.

Ultra DMA (UDMA) allows host computers send and retrieve data faster, removing the bottlenecks associated with data transfers, especially during sequential operations.

In addition to speed improvements, Ultra DMA delivers new data integrity capabilities to the EIDE interface. Improved timing margins and the use of CRC (Cyclical Redundancy Check), a data transfer error detection code, help to ensure the integrity of transferred data.

Ultra DMA is also recognized as Ultra ATA (UATA) and Fast ATA-2. It is endorsed by the industry's leading hard drive manufacturers, including Fujitsu, IBM, Maxtor, Quantum, Seagate, Toshiba, and Western Digital.

The Cable Select method of drive identification allows the system to identify Master and Slave IDE devices based upon the position (connector) the IDE device is attached to on the interface (ribbon) cable. IMPORTANT: Most systems do not use this feature. Unless you are sure that your computer system supports Cable Select, do not set up the drive with this feature enabled.

A special IDE cable select interface cable is required for system using the Cable Select feature. If your system supports this feature, refer to the system user’s manual or contact the system manufacturer for specific procedures for installing hard drives.

If the system hangs during the boot process after the installing the new hard drive ?either before or after setting the system BIOS ?the system may have a BIOS with a cylinder limitation. This may occur for hard drives that exceed 2.1GB. If this happens, consult with your system manufacturer see if the Disk Manager will help to solve the boot problem.

Many of the new drives have a passive locking mechanism holding the actuator in place, causing the drive to rattle when shaken. It is perfectly normal and no need to panic.

IDE interfaces are backward compatible. Older IDE peripherals will work with newer enhanced drives. However, ATA-5 peripherals will not be able to utilize their enhanced features.

Advertised transfer rates are based on the fastest speed at which the drive can send data across the ribbon cable from the drive buffer. The transfer stops every time the buffer re-fills. This process continues until a command is complete. Data transfer rates differ as much as system configurations. The one thing that analysts have control of is the speed at which data transmits across the data ribbon cable from the drive's buffer.

The reason is the fact that many hard drive manufacturers were already making and selling drives before the IDE standard was clearly defined. Older IDE drives have problems functioning in dual-drive configurations. This scenario is more prevalent when the hard disk drives are from different manufacturers. In some cases, two drives may not function together at all. However, in rare circumstances even new drives will not work together.

There may be a compatibility problem between the two drives. Here is a step to verify this assumption: Test the new drive by itself. If both drives work by themselves then it is best to conclude that there is a compatibility problem.

If this is found to be the case, try "swapping" (switching) the drive's roles. In this case, what was the master will change to be the slave and the slave will change to be the master.

There are three possible solutions to this question:

• Install the hard drive using manufacturer Disk Manager software.
• Upgrade the system Motherboard.
• Purchase/Install an Enhanced IDE Interface (EIDE) card with onboard BIOS that provides support for large capacity drives.

If your system does not have auto detecting capabilities, you have to set BIOS parameters to be appropriate for your drive after setting switches and jumpers. Most of models have the capabilities to allow the systems detect the newly installed drive automatically. Try to run FDISK and FORMAT program from DOS system prompt to set the drive partitions and to install system boot files and applications.

This is not necessarily a fatal error. Following are the steps to take in order to troubleshoot the problem:

Check all cable connections as follows:
- Make sure the power cable is connected securely to the drive.
- Make sure the data cable is connected securely to both the drive and to the system.
- Make sure the data cable is connected to both the drive and the system with the correct orientation (stripe on cable aligned with pin #1 on both the drive and your system or ATA controller).
- Test the data cable by trying a different cable or try the cable on a known working drive.

Verify the disk drive's jumper settings are set correctly.

If you are using a separate ATA controller card, test it by either trying a known working card or a known working disk drive.

Verify that the system BIOS (CMOS) settings for the hard drive are set correctly.

Make the drive the only hard drive device in the system and re-test. Try the drive in a different system if possible.

For additional technical information and troubleshooting, please click here to manufacturer's link page.

First, confirm the hard disk drive interface in the notebook computer is an IDE interface. The hard disk drive interface provides the communication path connecting various components of the computer.

Second, check the physical size of your hard disk drive. The majority of notebook computers today use a 2.5" disk drive. However the 2.5" form factor has three basic heights:

Less than 9.5mm height (approx. 0.37 in)

Less than 12.7 mm height (approx. 0.5 in)

Less than 19 mm height (approx. 0.75 in)

Since all notebook chassis are designed differently, manufacturers recommend using the physical height that is less than or equal to the physical dimension of your previous hard disk drive.

Third, verify the system BIOS supports higher capacity hard drives. Please consult your system manual or contact your notebook manufacturer to verify this information. Older BIOS (BIOS dated prior to July 1994) will not support drives over 528Mb. If a BIOS upgrade is not available, software drivers such as Ontrack’s Disk Manager and MicroHouse’s EZ-Drive can overcome this limitation. Many manufacturers provide free disk manager for their users, ckick here to download.

There are three basic requirements for Ultra160 SCSI:

1. Ulra160 SCSI Controller
2. LVD Termination
3. Ultra160 SCSI Device


Ultra160 SCSI is a SCSI interface and the following SCSI restrictions must still be met: must have a unique SCSI ID, the physical ends of a SCSI bus must be terminated, and termination power must be correctly supplied.

The 16-bit Wide SCSI connection (68-pin) is required to achieve the maximum LVD bus data rates (80?60 Mbytes/sec). The future of the 8-bit Narrow SCSI bus (SCSI-1) is limited. Most Ultra2 and Ultra3 SCSI designs will incorporate the standard 68-pin Wide SCSI connector or the 80-pin single connector (SCA-2) when multiple drives and easy integration are required.

Due to the specifications of Ultra2 and Ultra3 SCSI, Some LVD drives have no provision for setting termination on the drive. Termination must be provided by an external source. Similarly, termination power is limited to "Drive supplies the Bus" and "None". Check the documentation that came with your SCSI controller for correct settings.

Try the following:

Are all requirements for LVD being met (such as LVD controller, LVD termination, and an LVD device)?

Try a different slot for the controller. Not all PCI slots are created equal.

Ensure the terminator is LVD compliant.

Ensure there is not a single-ended device on the LVD bus segment.

Ensure the drive is not "locked" into single-ended mode with a misplaced jumper.

If an Ultra160 device is operating at Ultra2 LVD speeds, check SCSI controller configurations to ensure the maximum data transfer rate is selected.

You should contact the host adapter manufacturer for an updated SCSI driver when driver is needed.

To partition and format a primary hard drive under Windows NT, answer the drive preparation questions that display while you are installing your Windows NT operating system.

To partition and format a secondary hard drive under Windows NT, open the Disk Administrator icon and follow the instruction for partitioning and formatting a hard disk drive.

If you are using another operating system, such as Novell or UNIX, see the documentation that comes with your computer and operating system for information about partitioning and formatting the primary drive.

Check the hard drive to ensure that all power and signal cables are securely attached.

Check the SCSI ID jumper setting. No two SCSI devices can have the same SCSI ID. This includes the SCSI adapter.

Be sure that the last device terminates the SCSI cable. There must be a terminator or a terminating device at the last device on the SCSI cable. You must terminate both internal and external SCSI cables. Remove any terminators on devices that are not at the end of the cable.

If your new drive is at the end of the chain, be sure there is a jumper in the active-termination position.

If you are installing the drive in an IBM PC Server, be sure that auto-start is not active.

Remove the drive. Check for bent or misaligned pins. If there are no problems, reinstall the drive.

Most configuration problems are caused by incorrect termination or incorrect SCSI ID configuration. If multiple SCSI devices are attached, disconnect all other SCSI devices on the chain. Assign the highest available SCSI ID to the drive and terminate the drive. Try to detect the drive using your SCSI adapter utility program.

If you have just installed a SCSI adapter and you are now installing the SCSI hard drive, your SCSI adapter must be correctly configured before you can activate the drive. To configure the adapter, you might need to know the available I/O addresses, IRQs, and ROM addresses. If you are unable to configure your adapter, you will not be able to use your SCSI device. If you need more information about configuring your adapter, see the documentation that comes with your computer or SCSI adapter.

Termination power must be applied to the SCSI bus. This is not the same as signal termination. If your adapter does not supply termination power, power must be supplied by a device on the SCSI bus. Multiple devices can supply termination power to the bus, but only one device can terminate the SCSI chain.

Use the following cable length guidelines for attaching SCSI devices.

The device should not be less than 30 cm (11.8 in) apart on the device end of the cable.

SCSI-2 and Ultra SCSI device cables should not exceed 3 meters (9 ft 10 in).

If more than four devices are on the SCSI bus, the maximum cable length should not exceed 1.5 meters (4 ft 11 in).

Older SCSI devices might not support synchronous data transfer. If you have an older SCSI drive, CD-ROM, or tape drive in your computer, erratic operation or other problems might occur during synchronous data transfer. If problems occur, remove the other drives on the cable and retry the operation. If this does not solve the problems, try using your SCSI adapter utility to select asynchronous data transfer for use with your SCSI adapter.

If you are installing a hard drive with a capacity larger than 1 GB, you might need to install additional software or select additional setting on your SCSI adapter to use the full capacity of your new drive.

If you are attaching an Ultra SCSI device in an external enclosure and the faster data transfer rate does not work, use your Ultra SCSI adapter utility to disable the faster data transfer rate.

The electronics on the drive system board might be shorted to the computer frame. To check for a short, open the computer, support the drive, remove the mounting screws, and test the drive for proper operation. If the drive now operates correctly, you might have created a short by attaching the drive using screws that are too long.

Check for a jumper in the auto-start position. When you install a jumper on the auto-start pins, the hard drive motor starts when the computer is turned on. When the auto-start position is open the drive must receive a start command from the SCSI adapter before is can spin up. Some computers expect the drive to be spinning and do not wait for a command from the SCSI adapter. Also, you might have to select additional setting on your SCSI adapter.

If you need more information, see the documentation that comes with your operating system and SCSI adapter.
