AGAIN:Have you tried a different cable?
Yes ....different usb cables have been tried

Have you given this Ext drive a dedicated drive letter? If so what's the letter?
Yes I have with the PC that recognizes it... two can't see it so a letter cannot be assigned. ( through my computer an control panel>admin tools>computer mgt>storage>disk mgt routes)

If so have the three other PC's got card readers fitted?
All 3 PCs have SD card readers

EDIT: I think the laptop came with Vista pre installed. Have you upgraded to Win 7?
Where did the upgrade come from and are all the other PC's (How many are there
BTW?) using the same copy of Windows 7?
The laptop is a 2 month old Dell...There have been no OS upgrades on the others.
All are W7 Home Premium 64 bit .
There are 2 new laptops and a 2 year old PC. Originally had the invisibility problem with the desktop so I tried testing the subject external disk on my son's new lenovo and the disk could not be read on his either. So the disk has been tested on 3 W7 PCs and will only work with one

Thanks for your help!

Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1

OK Try this. On one of the machines where the drive is not recognised. Plug the USB in and connect to the drive. Is there a seperate Power supply to the drive or is it powered through the USB? Either way close down the PC, dont ut the power supply to the drive and reboot. See if that recognises the drive. BTW what letter did you assign to it?
