Vista does not show External Hard Drive connected through USB (USB 2.0 TO IDE)

I have formatted and partitioned Maxtor 30 GB HD and want to use it as an external extended backup storage device. I have set the Jumper to 'Master' and format type is NTFS. The HD works perfectly with my old PC (Win XP) as an external drive through USB. But when I attach it with my new PC (Vista Home Premium), the HD is shown in 'Device Manager' only and no where in 'My Computer' or in 'Disk Management'. I have tried different USB ports on my new PC but I couldn't be able to get it recognized by Vista yet. I have searched the internet and most of the solutions say about changing of drive letters and reformatting but my problem is that external hard drive does not appear in 'Disk Management' section at all in any form. Any help in this regard will be much appreciated.

 

Generally speaking, a single drive does not need to be jumpered. There are exceptions and yours might be one of the few. Try connecing it without the jumper and see what happens. Other than that, don't know what to tell you.

 

Thanks for the reply. I have already used various options of jumper setting even tried without jumper but no option went well.
