"slave hard drive not detected in bios but is detected in win2000 device manager but not in computer management or the my computer menu"
I believe you have your symptoms mixed up, or you're not interpreting what you're seeing correctly.
Depending on what is normal for you to see in the bios Setup version on your mboard, and what settings you are using, you may or may not see the drive listed in the bios Setup.
If you have the drive's connection set to None, with some bios versions the bios won't detect it automatically when the bios is set to that, and if the bios doesn't detect it, usually neither will Windows.
You haven't stated what your mboard make and model or your brand name system model is, so I can't look up what is normal for you to see there.
Windows usually cannot see the drive at all if the mboard bios doesn't recognize it.
If the Maxtor drive shows up in Device Manager, if there is no yellow ? or red circle with an black X through it there, it shows up in Disk Management.
The drive won't show up in My Computer or Windows Explorer unless the drive was partitioned using FAT, FAT32, or NTFS partitioning, the partition is formattted, and Windows recognzes the partition(s) as valid.
If the data on the drive is corrupted such that Windows doesn't accept it as valid, if there's nothing wrong with the drive, if nothing else, you should be able to delete the partition(s) on the drive and make it/them again in Disk Management, and then it/they should then show up in My Computer and Windows Explorer.
Some IDE hard drives - e.g. some Western Digital models - have two ways they can be set as Master - one for when the drive is by itself on the data cable, the other for when the drive is on the same data cable as a drive set to slave - you must jumper the drive correctly, otherwise the slave drive may not be detected properly.
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.
Your Maxtor 6E040L0 hard drive must beconnected to an 80 wire data cable in order for it to be able to reach it's fastest data trasfer burst speed - either 133mb/sec, or the max the mboard chipset supports..
The correct end connector of a three connector 80 wire data cable MUST be connected to the mboard - usually the right connector is blue, or in any case it's the one farther from the middle connector.
You could do this, but it requires that the mboard's bios must recognize the drive.
Check your hard drive with the manufacturer's diagnostics.

Hard Drive Diagnostics Tools and Utilities
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
