I was able to resolve this exact problem by performing a low level format of the device and reinstalling the firmware.

Please note that this procedure completely erases the contents of the device.

1) Visit the Samsung support site specific to your region, obtain a recent version of the firmware and save it somewhere accessible.
2) Turn the unit off, then hold down the record button ( top-most button on the right hand side ) while pressing the power button. If you are stuck in the USB-reset-cycle as I was, holding the record button down while it thrashed about was sufficient as well.
3) Momentarily you will be on the "Low Level Format USB Mode" screen, a prompt will ask for keycodes. At this point your are about to remove all data and firmware from the device, pressing rec+menu will exit this screen leaving everything intact. Otherwise tap in: LEFT,LEFT,RIGHT,RIGHT,TOP,MIDDLE BUTTON, BOTTOM. An asterisk will appear for each key entered, the device will then completely erase the flash memory.
4) Essentially you now have a USB flash drive, powering the device on will present a "USB Mode..." prompt, connect the cable and plug it into an available USB port on the computer.
5) The device will mount as a standard removable device called "YP-T9". Open the firmware zip file downloaded in step 1 and drag the two files to the device.
6) When copying is complete, safely eject the USB device from the system. Power the unit off ( might be necessary to hold down REC+MENU to force it off ).
7) Hold the power button to start the device back up and a "Upgrading Firmware..." message should appear for a few seconds, after which you'll be back at the familiar interface. You may need to customize menu language to the locale of your choice.

You can now sync the device to your collection and enjoy until the next time it happens.

Hope this helps!

Ipod classic 7th generation won't sync

Step 1:
With iTunes software, iPod users can manage their media libraries, purchase or import new content and synchronize their devices. The software has a number of convenient features, one of which is AutoSync. This feature will cause your iPod to automatically synchronize with iTunes immediately upon connecting the device to your computer. You can also set up iTunes so that you can manually sync your iPod.

Press the "Shift" and "Ctrl" keys on your computer keyboard simultaneously while you connect your iPod to the computer using its USB cord. Mac users will press "CMD + Option" while you connect. Continue to keep the keys pressed down while you monitor the iTunes window. Keep the keys pressed until you notice that Auto-Sync has stopped and your iPod icon has appeared in the Source pane of iTunes. Be patient, as this could take between 5 and 30 seconds. Right-click on the icon for your iPod in the Source pane, and then select "iPod Options." Click to put a check mark in the "Manually manage songs and playlists" check box. This finishes your task and you can now manually synchronize your iPod whenever you wish by simply clicking on the "Sync" button.

I installed new cartridges (Lexmark brank both black and color) and my printer won't work now.

A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected)> reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer (if USB connected). Then try to print again once the computer fully recognizes the USB connection or when the WiFi light on the printer turns solid green (if WiFi connected.).

If that doesn't help, try the steps below:

  1. Disconnect the USB cable connecting the printer from your computer.
  2. On your computer, go to Control Panel > Printers and Faxes.
  3. Delete the Lexmark print object.
  4. Reboot computer.
  5. Re-brick your printer by pulling out the power supply - black box where the power cord is plugged into on the back of the printer, and re-plug after 30 seconds.
  6. When the printer turns on, reconnect it to the computer.
  7. Wait until your computer fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, try to print a document to verify that the problem is fixed.

My Seagate freeagent 320GB won't show up on my computer. It was working fine yesterday when I backed up some important folders, then later on that day, I went to add something to it, and it told me...

Get the Testdisk app and see if it can identify the issue. You can repair the boot sector or create a new one with th is app. If it shows up in the drive list you have a good chance of getting the drive back.

When I plug in my Zune to my PC, my PC doesn't recognize it. I can't manage my music, etc. However, it does charge it when plugged in. Please help.

I am having similar symptoms on mine. Just began happening yesterday. When it's plugged into the USB port on my PC, Zune software thinks it's not connected. The Zune itself just keeps booting up repeatedly, but never stays on. When I put in on a charger, it works fine as long as it's on the charger. The moment I remove it from the charger, it shuts down. I've tried resetting it, to no avail.

Problem getting wii GUITAR working with RockBand 2 after a resync

first of all you should make sure you have fresh batteries and then try the special resynch via the red dot like button on the inside of the controller (press it at the same time as the one in sd card slot) if that doesnt work try just moving closer to the wii at far distance the controller signal gets weak. if its not that then its a hardware issue

Palm z22 USB won't stay connected

Hi, I also had the same problem exactly the way you described it. What worked for me is putting in the original installation cd that came with the palm. Run the installation and I think the computer will recognize the palm and stay connected. Hope it works.

Connected, but no recognition from PC

Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
