I've hooked up a Seagate 40MB Portable External Hard Drive to my mother's computer, and the LED on the unit indicates that there's activity of some
sort (constantly flashing blue light), but when I look under Device Manager and Disk Management, I can't find the unit listed anywhere.
When I click on Device Manager, and then on each entry under Universal Serial Bus controllers, every one of them says the device is working properly. If it's of any consequence, there are 8 entries in this category, even though there are only 4 USB ports being used (by mouse, webcam, printer and this external hard drive):
Logitech USB Camera
SiS 7001 PCI
to USB Open Host Controller (two of these)
to USB Enhanced Host Controller
USB Printing Support
USB Root Hub (three of these)
Under Computer Management, all I see is:
Disk 0 - Basic 74.53 GB Online (the internal HD
that came with the computer)
Disk 1 - Removable (E: ) No Media (which I think refers to a memory stick)
CD-ROM 0 - DVD (F: ) No Media
The computer's a Sony VAIO, with WinXP SP2
. I've run through the "External Drive Troubleshooter - Windows Detection Issue", but as far as I can tell our computer meets all the criteria, so I don't know what to try next. I've tried using a different USB port to connect the external drive, I've tried connecting both USB plugs from the external HD
to the computer (it comes with a Y connection - if it can't draw enough power with a single USB connection, you're supposed to plug in both; with both connected, the unit makes little chirping noises in addition to the flashing blue LED - not at all like the whirring noise my own external HD
at home makes), and I've tried rebooting the computer.
Does it sound like something's wrong with the external HD
or with our computer (or isn't there enough info to determine this)? If I can't get it to work, I'll have to have my mother return it, since she'll never bother to figure it out...
Advice anyone? Thanks!
