|Newer mboard bioses will recognize an IDE drive jumpered as slave if it's by itself on the 3 or 2 connector data cable, but the operating system may not, and even if it does, that situation causes problems sometimes. |
Different makers, and different models of the same maker, do not necessarily have jumpers in the same positions (or no jumper) for the same purpose. Check the label on the drive, or check the jumpering on the drive's web site for the model. Sometimes the label is upside down with respect to where the jumpers are - if the label shows where the power connector in relation to the jumper pins, go by that.
If the IDE drive is on a data cable with a drive jumpered master, some makes/models (e.g. some Western Digital models) of hard drives have two ways they can be jumpered as master - one way when they are alone on the cable (e.g. Master, Single) - the other way when there is a slave drive on the same cable (e.g. Master with Slave). A slave drive may or may not be recognized properly when the master drive is jumpered the way for when it is it by itself.
The proper connector on the 80 wire IDE data cable MUST be connected to the mboard - it's often blue, but in any case it's the one farther from the middle connector on a 3 connector cable. .
If you have two drives on the IDE data cable, either
- one must be jumpered master, the other slave.
- or - both must be jumpered cable select ( the drive connected to the middle connector on the 3 connector cable is seen as slave, the one on the end connector is seen as master).
Don't mix cable select and master / slave jumpering on the same data cable.
In this case, make sure the other drive is not jumpered cable select - when you mix cable select jumpering with master / slave jumpering, some combinations work, some do not.
In Microsoft operating systems, the drive WILL NOT show up in My Computer or Windows Explorer if the drive has no data on it(and is not partitioned and formatted), or if the drive is partitioned with something other than what the operating system can recognize - that must be NTFS, FAT32, or FAT partitioning for XP or Vista - or if the drive is partitioned but not formatted, but it always shows up in Device Manager and Disk Management if the mboard's bios detects it.
Similar probably applies to Ubuntu and other operating systems.
It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.
Try another data cable if in doubt.
