Look for the new drive in Windows Disk Management. You may need to partition and format the drive.

If the external drive enclosure came with a hard drive already installed in it, the hard drive inside of the enclosure has already been software partitioned using the NTFS method and formatted - it should show up in My Computer (or Computer in Vista or Windows 7) or Windows Explorer fine if other requirements for the external drive have been met.

If you bought the external enclosure separately and installed a new hard drive in it, the new hard drive has no data on it. You must do as OtheHill has said.


The USB port you plug the external hard drive into must be able to supply the full max USB spec 500ma, and even then it won't be recognized in all USB ports.

If it WAS being recognized properly previously, if you have not dropped the external enclosure since the drive was last detected properly, you have probably damaged data on it and you need to use a program to fix the data damage.

There are references in that that tell you how to find Device Manager and Disk Management in XP. The same things apply, except how you find those things in Windows 7.
E.g.
Double click on Computer, select System Properties in the bar at the top of the resulting window, the link to Device Manager is on the left side of the resulting window.
Control Panel - set to display as Large icons or Small icons, not Categories - Administrative Tools - Computer Management - Disk Management.

You have NOT supplied enough information !
The more information you supply, the better !

If you bought the external drive encolsure separately and installed a new hard drive in it, in.......

Control Panel - set to display as Large icons or Small icons, not Categories - Administrative Tools - Computer Management - Disk Management (on the left side of the screen)

....you should see that the space on the hard drive inside the external drive is shown as Unallocated, if nothing else is wrong.
Do you see that, or something else ?

If you see Unallocated, place you cursor over the drive space where that Unallocated is, RIGHT click, and choose New Simple Volume.

- If you want more than one partition (drive letter) on the external drive, reduce the default size it wants to prepare - 1,024 mb per gb.
Otherwise, leave it as it is.
- Next -
- let it assign whatever drive letter - you can change that if you need to later
- Next -
- let it format it the way it wants to
- Next -
- you will see a summary of what it's going to do. Click on Finish if that looks okay or you're not sure, click on Back if you want to change some setting.

If you wanted to make more than one partition (drive letter) on the drive, repeat the steps for the unallocated space.

The partitions (drive letters for them) that have been prepared by doing those steps will now show up in Computer and Windows Explorer in Windows.

(Those steps both software partition the drive partition using the NTFS (NT File System) AND format that organized space - you're NOT not just formatting. If the partition is exactly 32 gb - 32,768 mb - or smaller, you can choose FAT32 (File Allocation Table 32 bit) software partitioning instead of NTFS software partitioning.)
.........

Your hard drive inside the external enclosure will NOT be detected properly if it's USB connection is not getting 500ma, at any time !
...........

If your hard drive and external enclosure came as a set with the hard drive already installed, what does it say in Disk Mangement for the space on the hard drive ?
