Philips 9450 is not recognized

Most likely a problem with the reader on the CD/DVD Drive.

Very easy to swap out a different CD/DVD Drive. Add the new device and see if that resolves the issue.

You can go to Philips site and download the latest drivers to your pc. Drivers is what lets the pc and player communicate and sync.
You can also go to my computer, then find the drive for the player there to see if it shows up and computer recognizes it. I would update the latest drivers or try KM Player which is free and works better than windows media . They are kind of the same but don't need codecs with KM Player. KM Plays everything as well as syncs with your devices.

Check the Disk Management console to see if the hard disk is partitioned and formatted.
Right-click My Computer and select Manage in the popup menu.

Win 2k, XP, Vista, and Win7 have a CONTROL PANEL applet called Administrative Tools - opening that there is a sub applet called Computer Management - and openint that there is another sub applet called Disk Management. In Disk Management you will usually find all of your drives (including those that don't show up in Windows Explorer). A new drive will probably be listed as drive 1 or something like that and shown as UNALLOCATED space. Right click that drive (my best advice on how to be sure its the right drive is to know the drive size .. ie 500 gb or 750 gb etc AND seeing that it is inactive) to activate it and to partition and format it.

If this problem occurs then your ML648B needs to be formatted.

1. Connect your ML648B to your computer with Windows XP or later.
2. By default your computer will recognize ML648B as GPX MTP Device. Press the POWER button from top of your ML648B, to change it to USB mode connection. You will also see USB on the screen of ML648B.
3. ML648B will now mount 2 drives, one as Tools (as CD-Drive) and second as Removable Disk (Drive) – under My Computer on your Windows Desktop.
4. Right click your mouse and then select the Format option. When the Format Removable Disk window appears select the Start button to start formatting your MP3 player.

Check device manager and see if its showing a conflict.If so you will need to click Start -> Run, type Regedit

1. Remove the Upperfilters and Lowerfilters values completely from the following registry key (Windows 2k/XP):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
2. Restart your computer.
This worked for me and CD's work again.

Installing the latest Windows Media Player solved the problem.

What I would recommend you to do is to make sure that your device is under MTP mode instead of MSC...to do that go under menu,setting, usb and then there should the two mode listed there...then you want to plug your device in the back of your computer..not in the front..tghat is very important....once you do that..open up your windows media player...click on your start thee sync panel..if your device is recognize properly it will be showing there on the right side..and if its not listed properly, it will say connect a device..if thats the case..click on your start menu right click on computer and then click on propetties, click under hardware and then device manager..your device should be showing there...check under disk drives to see if your device is showing there and if it doesnt you want to right click and hit uninstall...we dont want your device to be under disk drive ..we want it to be under windows portable device...once you uninstall it...go to http://www.sandisk.com/DriverDownload/index.asp and find the driver for your device..and then connecct the device on the back of your computer...it should work properly..if you are still having any problems..let me know..i would be more than happy to assist you..
Please rate accordingly
Thank you

Software and drivers are only available for Windows XP, but may also work with 2000.

Check to see if the Philips Device Manager recognises the drive.

Note: the player does not show as a removable drive.

Also make sure you have Windows Media Player 10, and use this to try and transfer files with the Sync function.

Hi, i have installed thousands of Internal Floppy drives and there aint no conflicts between win/95/98/me and xp. all discs should be compatible, unless you took it from a apple machine for example. did it work when you put in a new floppy drive? all the best John
