IDE devices and hard drive guide
This is for those of you who are not expert PC builders.
I will give a basic explenation of how to setup IDE devices and how to deal with hard drives larger than the bios can handle.
IDE setup
Basic rules:
1.In most cases 2 IDE devices of differant interface (PIO, ATA33, ATA66 ATA100, ATA133) If connected on the same IDE cable will both work at the lower interface level or might even both default to PIO mode (slow).
2.IDE devices with ATA66 or higher interface need an 80 wire ATA cable. If an older 40 wire IDE cable will be used the drive will default to ATA33.
This cable must be connected correctly unlike the older one. The blue end goes in the motherboard, the black (last) for the master and gray (middle) for the slave.
3.While connecting a CD/DVD and a CDRW on the same IDE channel it is recommended the writer be master.
4.If 2 devices of differant interface mode (ATA33 and ATA100 for example) are connected on 1 IDE channel it is recommended the faster be set as master.
5.Installing a disk with an interface faster than the board can handle is usually not a problem since it is backwards compatible.
If problems do come up use the manufacturer's software to lower the drive's firmware setting to the appropriate speed.
Jumper settings
IDE devices must have 1 of 2 attributes: Master or Slave.
This attribute is how the IDE controller addresses the device.
A device can be set to Cable select, this will set the device automaticly according to it's position on the IDE cable, the middle connector is slve, the furthest one is master.
You can not have 2 devices on 1 IDE channel with the same attribute, unless it is cable select, which will autoset the drives to master and slave.
W.D drives have a separate setting for master with slave and stand alone (master without a slave).
What do I do if the bios of my motherboard doesn't recognize drives of a certine size ?
Here are your options :
A.Find a bios update for your board. If the manufacturer of the boad has writen a bios to support larger drives it might solve your problem.
This is the best solution if such an upgrade is available and you feel you know how to flash a bios.
B.Install a PCI IDE controller card, this card must have it's own bios!
This is the 2'nd best solution as it has extra costs, but it is the safest and might be faster than the outdated IDE controllers on your aged motherboard.
C.If you do not need to boot from this new drive and intend to only use it for storage while keeping the boot drive on the old HDD you do not need the bios te even detect the drive!
Set the coresponding IDE device in the bios to none and allow windows to detect the drive.
Don't forget to partition and format the drive in windows.
A good solution, but remember the drive won't be accessable in DOS mode.
D.Use the cylinder limitation jumper to make the bios detect the drive as a smaller volume than it actually is.
This is accomplished by jumpering the drive according to the manufacturer's instructions ( can be found below ).
Once you have done this your bios should detect the drive according to the following rule :
8-32GB->8GB
32 and up -> 32GB
At this point the rest of the drive won't be accessable, to be able to access the rest of the space you need a dynamic disk overlay utility which the manufacturers provide.
These are generally only good under windows 95/98/ME, not for linux or windows NT/2000/XP.
This solution is cheap, but not always dependable and tricky to accomplish.
Jumper setup for most drives available on the market :
Jumper settings below are with the drive oriented:
|----IDE----||jumpers||power|
They may not match all drive models! You can usually find this information directly on the hard drive body.
