I just bought a new 4gb USB stick......when I plugged it in XP went through the usual, "new device detected.......your new device is now installed and ready to use" stuff, but when I click on it it tells me to "insert a disk into Drive J". Right click/Properties tells me: Type: Removable disk, File System: Unknown, Unused Space: 0 mb, Used Space: 0 mb, Capacity: 0 mb. If I Right Click and select Format I get the same "Insert a disk" message. My other USB stick lists the File System as FAT32. I've gone into Computer Management.....it is listed but treated like an optical drive with no DVD/CD in it. There are no options to format....only Change/Assign Drive Letter and Properties. Every other USB stick I've used has just plugged in, been recognised and usable straight away.......am I just being a noob and missing something simple or is it faulty.
