New Drive? Old Drive? Was It Working Previously?

If it's a new drive, then you probably need to format it in Disc Management from the Control Panel.. (Unfortunately, you didn't tell us which operating system you're using on the computer, or make and model, or much else, so we would be guessing to give you any specific advice.) And since we frequently give advice about making backups of such devices, do you have a backup?

If the drive is an old drive that worked previously, have you tried plugging the drive into another computer? Is it recognized and working correctly on another machine? External drives frequently fail after a small amount of use so we'll need a better explanation about any error messages you see when attempting to use the drive..

Hope this helps and let us know more.

What do you mean by ..

"and when i try to update the drive it cant complete the update"?

What are you trying to plug it in to?

How did you "checked all the usb hubs"?

If using Windows XP does Disk Management (Ctrl panel > Admin tools > Computer Management ) "see" the drive? If so what does it indicate?

If not using Windows XP you have to tell us these things. Just above where you clicked the Submit button when making your post there was some RED TEXT just under a bolded "Please read before posting" that says:
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.

You have to help us help you.

The additional information is helpful

In computer management you want to select Storage then Disk Management in the left column. You will then see all the drives and partitions in the right column. The upper right shows the file system on each drive/partition and its status as does the lower right window. What does it indicate about the drive when you look at it? You can also right click the drive and look at the drive properties - what do they show?

It did work but now doesn't AND it also doesn't work on another PC. This indicates that most likely the drive itself has a problem or the USB converter within the external case has a problem and needs to be replaced with another external case. You can check that by removing the drive from the cqase and mounting it internally or in another external case or with a temporary IDE/SATA to usb CABLE AND POWER SUPPLY.

It may also be non-functional because of having been formatted as FAT32 which seems to have a particulat problem with partition table corruption when attached by USB. That would mean that you would need to either learn to use a sector editor to recover lost data or send the drive off to some data recovery specialists such as Drive Savers or Ontrack Data Recovery and that is not inexpensive.

Depending on the exact problem and what the Disk Manager indicates you might be able to re-partition and format the drive using Disk Manager.

The USB drivers are native to Windows XP so there are no drivers to update and they are either working and allowing you to use FUNCTIONING USP peripherals (such as drives and flash drives, and keyboards and mice) or they are corrupted and not allowing ANY USB peripheral to function. Check the ports on the computer by using a known good USB device (such as a flash memory stick drive) and do not depend on what Device Manager indicates unless it is showing a problem.

RE: "i clicked on the read first thing an nothing came up." -- you are expected to READ the read before posting note, you are not expected to click on it or it would indicate to do so.

Danger Will Robinson!

You might want to back up whatever is on your external drive. I had a similar problem with a WD external drive and it would sometimes be recognized and sometimes not, but gradually it was not recognized more and more and finally not at all. I didn't back up my data and I am now screwed.
