external HDD not working in Win2003

Well it has to be a driver problem with 2003 the only thing that I can think of is updating the USB drivers for the M'Board or plug in USB Card on the 2003 install.

You can try going into Device Manager and see if it is seen there about the only possible thing that I can think of the the File Table being FAT and not NTFS. I haven't tried plugging in a FAT external HDD to a 2003 install as all my external drives are formatted in NTFS just so I don't get masses of "Slack Space" on the drive.

A questions i have to ask.
Do you have any mapped drives?

If you do and even if you don't go in and check disk management Right click my computer > Manage Disk Management > See if it's in there and see what drive letter it,s been allocated.

If it is there change the drive letter to something else.

Well it should be working as you have said that it is already working properly on an XP installation but not on this computer right?

I've run across some LT drives that just do not want to be recognized by 2003 when fitted to USB caddies and that could be the problem but if it is a IDE or SATA it should be working unless you have so many partitions or mapped drives that you have run out of Drive Letters.

Go into the Control Pannel then Administrative Tools then Computer Management and then Disk Management and see if it is listed there. The only time I've ever seen a problem with these drives is when they are not jumpered correctly they should be set to Master or only if that is not available then Cable Select but it shouldn't be working properly in XP if that was the case.
