I got a new computer running on Windows 7. It read my USB for about 5 weeks untill it just would not apear in computer. Every thing I own is on my USB, because I don't have anything on my computer because it has not disk space! I have to use my old slow XP computer to open my USB.

Since can read the flash drive on an XP box, the stick itself is probably OK — that narrows the problem to the Windows 7 host (port, mount/drive-letter, or host-side software). ’s Microsoft pointers and ’s driver/restore idea are relevant; the checklist below complements them with focused, data-first diagnostics and a few things people often miss.

  • Verify the port and host see the device: plug the stick into several physical USB ports (rear ports on a desktop first). Confirm other USB devices work in those same ports.
  • Device Manager: look for any “Unknown device” or entries under “USB controllers” that show errors. Note the error code in Properties — that often points to a specific fix. Uninstall the problematic entry and scan for hardware changes to force re-detection.
  • Disk Management: Right‑click Computer → Manage → Disk Management. If the drive appears without a drive letter, use Change Drive Letter and Paths → Add. If it shows as RAW or Offline, avoid formatting if data is important. “No Media” or no entry at all usually means a hardware/port issue.
  • Event Viewer: check Windows Logs → System around the time the drive was plugged in for USB/disk errors. The logged Event ID or message can be diagnostic.

Also worth checking: BIOS/UEFI USB settings (ensure controllers aren’t disabled), and Windows power options — disable USB selective suspend and clear “Allow the computer to turn off this device to save power” on each USB Root Hub. If the stick is readable on XP, copy the entire contents off that XP machine immediately before attempting repairs. If Windows 7 shows RAW but the XP copy succeeds, reformat the stick on the 7 machine after backup and then restore files.

If none of the above exposes the device on the Windows 7 system, the host’s USB controller or its chipset drivers (from the motherboard vendor) may need attention, or the port hardware could be failing. For critical data that stops being readable, avoid writing to the drive and consider professional recovery.

Try reinstalling your USB drivers which came up with your pc, or doing system restore on your windows to that day, when your USB really was working.Actually, I don't believe that this windows stuff posted above could solve this problem..
