External HDD driver?? USB to ATA/ATAPI bridge?? HELP PLEASE

im having a problem with my external hdd, i have two, one WD external works
fine with vista, then i go to use my new one (formatted it using xp etc_) on
my laptop with vista and it wont pick it up >< i mean surely something
natively supported by xp would be natively supported by vista as well. Unless
im doing something wrong....lol...but my usb mouse and other external etc etc
was all picked up fine.

I plug my hdd in and it comes up installing drivers, then says windows needs
to install software for your USB to ATA/ATAPI bridge, then i click locate and
and install automatically, then it just goes into USB to ATA/ATAPI bridge
driver failed. i have googled the driver with out luck. i do not have a
driver cd. the brand is NEXT with a standard 500gig seagate drive in it... is
this something that ive done wrong??
Im running vista 32bit home premium on a dell xps laptop.

Any help would be awesome guys
