This past week, I worked on a computer that belonged to one of my supervisors at work. It was a Dell Dimension 3000 system that had a Windows XP Home Edition SP3 OS that was so heavily infected with malware that I had to manually back up all of the personal data on the drive and use the hidden restore partition on the drive to completely wipe the drive clean and reset it to factory condition and restore the data from there. One of the flash drives that I backed up the personal data on was a Patriot Xpress 32 GB USB 3.0 flash drive that I purchased last year. This drive had several system files on it that were part of that data. When I attempted to connect the flash drive to my Toshiba Satellite Pro laptop (which has Windows XP Pro SP3 as its OS) via one of its USB 2.0 ports, the flash drive made a quick connect/disconnect sound, and never appeared in the My Computer window as an accessible drive. There was also no "Safely Remove Hardware" icon showing in the System Tray to indicate that this drive was connected to my laptop. So I pulled the Patriot XPress flash drive from that USB 2.0 port and tried it on a different USB 2.0 port and received the exact same result. So I disconnected it from the USB 2.0 port on the Toshiba laptop and connected it to a USB 2.0 port on my homebuilt desktop computer that has Windows 7 Ultimate 64-bit as its OS, and the Patriot XPress flash drive made the normal connect sound in Windows 7 and showed as an accessible drive in the Computer window of Windows 7. When I went to delete the system files on the drive, it gave me a warning stating that if I were to delete them, Windows might not function properly,..blah, blah, blah. Knowing that these were system files from a completely different OS, I went ahead and deleted them without issue or consequence and managed to get all the available usable space back on the flash drive.
My question is this: Why would this drive be detected properly when I connected it to both the computer that I backed up the data from (so I could restore the data back to the computer) and to my Windows 7 desktop system, but not to my laptop? Any ideas?
