|"Do you mean RAW drive? Did you format the drive?"|
If it's a new drive, or a used drive that has had it's partition(s) deleted from it, Windows will NOT show a drive letter for it in My Computer or Windows Explorer until the drive has been software partitioned and formatted using something the operating system recognizes.
In Windows, you do that in Disk Management.
(e.g. Control Panel - Administrative Tools - Computer Management - Disk Management)
The drive shows up there as RAW before it has been software partitioned and formatted.
For Windows operating systems 2000 and above, it recognzes only NTFS, FAT32, and FAT software partitioning. Windows Setup (for 2000 and up) only allows you to use NFTS for partitions larger than 32gb. If you want to use FAT32 for partitions larger than that, you can use third party programs to do that, such as hard drive manufacturer's free drive preparation programs, and Windows (95 OSR2 and up) will recognize the FAT32 partitions fine.
If you're installing Windows on the new or otherwise blank drive by booting from a Windows CD, Setup will software partition and format one partition for you, if you so choose - you DO NOT have to make only one partition that fills the entire hard drive, which is the default - in fact it's a very good idea to make at least two - when it shows the default size it wants to make the partition, change it to a smaller size - keeping in mind there are 1, 024 mb per gb in the binary way of expressing the size Windows and the mboard bios uses. You can software partition and format one or more partitions in the remaining free space on the harddrive after Setup is finished in Disk Management.
NOTE that if there is/are other drives present on the system when you run Setup that have data on them, for 2000 or XP, if you want Windows to see itself (the partition Windows is installed on) as being on C, you must either
- disconnect the data cable connector to all other hard drives,
- or set the connection the other drives are connected to to NONE in the mboard's bios Setup,
- or HIDE the other hard drive partitions with a program such as Partition Magic (you must do that if there is already (a) partition(s) on the drive that already has/have data on it/them and you are installing Windows onto one of the partitions.)
(you may also need to change jumper settings on IDE drives if more than one hard or optical drive is connected to the same data cable)
BEFORE you run Setup.
If you want to have a dual or multi-boot situation, it's easy to make that possible later after Setup has finished and you have reconnected all your hard drives.
Wd2500bb is an IDE (a.k.a. EIDE; PATA) drive.
The IDE data cable you connect it to must have 80 wires in order for the mboard to support the max burst data transfer speed the drive can achieve.
80 wire data cables usually have two or three different colors of connectors.
The proper connector on one end of the 80 wire data cable must be connected to the mboard - usually it's blue, but in any case, it's the one farther from the middle connector on a 3 connector data cable.
You may need to change the jumper setting on the back of the drive if it is on an IDE data cable with another drive.
Either both drives on the same data cable must be set to cable select, or one must be set to master, the other to slave.
The jumper settings are shown on the label on the drive, or, see this:
This drive must be set to Dual Master or Dual Slave if there is another drive on the same data cable, if you use master/slave settings - it is likely it will not be recognized properly if jumpered or set otherwise.
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.
