I have a Philips 250 GB external hard drive (SPD5110CC) which has been working fine, until this morning, when connected to a PC running Vista Home Premium SP1.
Now, when it is plugged in, it is not recognised by my PC and it causes Windows Explorer to hang - it no longer shows up as a drive in Explorer. Likewise, it causes the Disk Management section of Adminstrative Tools - Computer Management to hang. Unplugging the USB connection to the HD immediately restores the functionality of both Windows Explorer and Disk Management.
The HD still works without any problems on a PC running XP Home SP3 so it doesn't appear to be a mechanical fault with the HD.
I've also tried three different USB sockets on my Vista PC but it makes no difference. Also, another external HD is continuing to function normally on my Vista PC.
A system restore has not solved the problem.
The Philips drive didn't come with any dedicated Vista drivers and up until today has worked faultlessly.
I would appreciate any thoughts on what might be wrong.
I have almost exactly the same problem with my LaCie USB hard drive. It's been fine but is now no longer lisyted in explorer or Device Manager. The Laptop (Dell Inspiron 9400) chimes when it's connected/disconected but shows nothing. It works fine on an XP laptop. Did you get anywhere? can anyone help? Be well
Thanks Roger Finally gave in and reformated the drive on an XP laptop....made no difference. Tried the 'delete infcache' solution, deleting USB and Drive files in Device manager. Situation still exactly the same....Tried differnet registry repair tools....nothing Anyone got any more ideas.
