Seems your SOL with Windows 2000. I checked Sony's site and the model you have is not compatible with your OS. Return it or get XP. Your system sounds like it has the requirements for Windows XP. Sorry but that's the best I can tell you.

I had the same problem after using this product for a month, suddenly it showed the warning of write protection.

I even contacted the sony customer center but to no avail. their answer was of no help at all. so here is what i did to make it work: 1) First install "QuickTime version 7.2" or later (you can download it from torrent if you are unable to register it, i.e. with a crack) 2) Then install "Windows Media Player 11 " (you can download it from torrent if you are unable to validate it, i.e. if WinXP not original) 3) Now install "Media Manager for WALKMAN" (a compatible software provided by the sony company to interact or communicate with the walkman), freely available for you to download at sony's website.
After the installation, connect the walkman to your computer. Now it should easily add or delete data from you walkman using this software or without it as well.

U need to upgrade the firmware,you need to download the firmware from here: http://support.sony-europe.com/dna/downloads/firmware/firmware.aspx?site=odw_en_GB&m=NWZ-B135&f=FRM_NWZ_B13x_f after downloading,run it and then connect the player to system while holding the "volume -" button...it should be detected and the firmware would be restored.

Hi hellohello21,
attach the supplied cable directly to the computer's USB port (don't use any other extension cord simultaneously). If that doesn't work, check if you've some problems with your USB driver.
