Symptoms:
1. Plug in a known working 16GB USB Flash drive (FAT32).
2. Device is recognized and shows up in Device Manager within a few seconds but not mounted.
3. Drive activity LED flashes for about 1 minute
4. Then it either mounts the drive normally and shows it in Explorer
OR
Explorer displays a message saying the drive cannot be accessed and needs to be formatted (when viewed in Disk Manager, it shows file system as RAW) Trying to format the drive at this stage fails.
But the flash drive is actually functioning consistently fine when used in my WIN XP machines and OSX machines. I'm pretty sure there is nothing wrong with the drive.
Sometimes uninstalling the USB Flash drive and USB Mass Storage drivers for the particular USB port in Device Manager, and then scanning for hardware changes, results in a successful mount. Sometimes not.
Have noticed in Task Manager sometimes multiple copies of DLL process associated with Safe Removal function. I always use Safe Removal to unmount the drive.
Have noticed it takes a long time to display directory contents of flash drive for the first time once it is successfully mounted.
Have searched through many threads dealing with this or similar problems but can't find any explanation for my problem
Can anyone help please?
