Sharing USB external hard drive (HDD) on a home network
I have had somewhat similar experience. My home network has four computers (WinXP-pro, WinXP-pro, WinXP-home, Win98 ) linked together. The two USB hard-drives (one on USB 1.0 port and one on a USB 2.0 port) connected to the WinXP-home machine can no longer be seen by other computers on the network. As in your case, when I look at "My Network Places," the WinXP-home's USB HDD's are listed, but access is denied.
Any of the machines can access any of the shared files on the WinXP-home's C:\ drive, so the network is working. Furthermore, if the WinXP-home's external USB HDD is physically moved and connected to a USB port on one of the WinXP-pro machines, it can be viewed by other machines on the network, so the problem is not with the specific HDD. Of course, the files on the external USB HDD can be accessed directly from the WinXP-home machine through the "My Computer" panel, so the HDD is working properly. And finally, the problem does not appear to be drive letter related as the problem is encountered on both the HDD manually assigned drive letter "U" as well as the UDD with automatically assigned drive letter "E".
In the first paragraph above, I say the external USB connected HDD can no longer be seen by other machines on the network. Up until about two months ago, I used to be able to read and write to those HDD. I'm uncertain as to what has changed, but I've diligently sought to make sure all sharing parameters are correctly set.
In the past, I've suspected my Norton Antivirus software, but I'm running Norton on all of my machines. Also, the problem persists even when I temporarily turn on Norton Antivirus and worm protection. Thus, I've concluded that the problem is something associated with an interaction between WinXP-home and either an Norton Update or a Windows Update.
Moving the HDD to another computer would mean that I'd need to have that second machine turned on when ever I wished to address the external USB hard drive from the WinXP-home machine. The idea suggested in another reply of buying a device that would allow direct connection of the USB HDD to the network is an interesting option and will be investigated.
Finally... All WinXP OPsys have been updated with SR-2 and later updates.
Any suggestions as to how to solve this problem will be appreciated.
