Caviar 31000 hard drive won't initialize

Specs: Windows 7
Hi, I have windows 7 on my computer. I am trying to run an old wd caviar 31000 1gb hard drive as a slave but there appears something wrong with this hard drive. I have connected the ide and sata and tried jumpers in all 3 positions (master slave and cable select) but none will work.
The BIOS recognises the drive when it is auto detecting but it flashes in red. When I get to windows 7 the drive is not recognised anywhere, I've tried to go to disk management and the drive shows up as not initialized which should be done automatically. When I try to do it manually windows gives an error saying that the drive cannot be initialized "I/O error".
Is my computer having windows 7 the problem, is it not compatible?
Is there something I should be setting in the BIOS to set as slave as well as on the jumpers?
Does it need formatting and if so how can I do that if I can't get on it?
Any help would be greatly appreciated.

Sometimes you DON'T install a jumper to set an IDE drive to one of master or slave - that varies - but at least one of those must be jumpered, and CS is always jumpered if you want to use it.

Make sure you're installing a jumper on the right pins - sometimes the label on the drive is upside down with respect to where you set them - if the label shows where the power connector is with respect to the jumper pins, go by that - or look online on the manfacturer's web site in the info for the model .

If the drive is NOT on the same data cable as another IDE drive, it must be set to master (or master - single or similar if that applies, see below), or CS.

If the drive is on the same IDE data cable with another IDE drive
- if the other drive is jumpered master, the 1 gb must be set to slave
- if the other drive is set to CS - cable select - the 1gb drive must be set to CS. (in that case, the drive on the middle connector on a 3 connector data cable is seen as slave, the one on the end connector is seen as master)

NOTE that if the other drive is a hard drive, some hard drives, e.g. Western Digital - have TWO ways they can be set to master - e.g. master (single), or similar, for when it is connected by itself on the data cable, and master (with slave), or similar, for when it is on a data cable with another drive set as slave.
If the other drive is such a hard drive, or if you set this 1gb drive to master, the other to slave, if it has that situation, you MUST use the master (with slave) setting otherwise the slave drive won't be seen properly (or both drives could be set to CS).

80 wire IDE data cables must have the proper 40 pin hole end connector connected to the mboard - usually that's colored blue, or in any case it's the one farther from the middle connector on a 3 connector data cable.

80 wire data cables always have at least two if not three different colors of connectors.

Usually you can only install 80 wire data cables one way, because of a external tab on the connector that must line up with a slot in the shroud around the header it plugs into.

You can use a 40 wire data cable with the 1gb drive, if it's the only drive on a data cable, or if the other drive on the data cable is an older IDE hard drive that can't do better than UDMA33, or a CD-rom, or a CD-burner (only), or a DVD-rom drive, or an older DVD burner drive.
If it's connectors have no external tab, they can be installed backwards on a header. The stripe on one side of the data cable must be on the same side of each header - either all on the pin one end, or all on the 40 pin end - on most hard drives, most optical drives, the pin 1 end is usually next to the power connector - the pin one end is usually marked on the mboard with a 1 or an arrowhead. All the IDE and floppy headers have the stripe on the same end if they're close together.

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.

The drive will not show up in My Computer and Windows Explorer unless it is working properly, AND it has been partitioned and formatted using something Windows recognizes - FAT, FAT 16, FAT 32, or NTFS.

If all of that appears to be correct and the drive is still not shown as working okay in Disk Management - you may need to partition and format it first if it's been wiped - that's done in one combo step if it has only 1 partition - then test the drive with Western Digital's diagnostics.

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.

"The BIOS recognises the drive when it is auto detecting but it flashes in red".

Does the BIOS identify the drive by both the model number and capacity? I don't know about a WD drive that old but newer IDE drives by WD have an additional jumper position for Master alone. If the WD is the only drive on the cable that would be the correct position.

Yeah, those drives also had the 'no jumper for single drive on the cable' designation.

That drive may be partitioned as FAT16. Does Windows 7 see that OK?

Or it may have been manually setup in its previous PC's cmos in C/H/S instead of AUTO.

You're not really green until you're soylent green.
