You need Acronis or Partition Magic to see if there is a hidden partition on your drive this should contain Drivers etc for your Hardware if there is you then need Drive Image to copy the hidden Partition to a CD then restore the image to the new Drive after creating a new Hidden partition on you New Drive
Try going into FDISK and deleting any partitions that are there. After that, format the drive as normal
There's a program on the boot floppy called "Tattoo.bin". IIRC, you can do it yourself by running it after you've formatted the drive. Having said that, I tried it (with the help of PB support) and it didn't work.
Your best bet is to take it back to PC World and get them to do it for you. Shouldn't take them more than a couple of days.
depending on the model of packard bell there several commands to do this. best advice would be to contact pc service call or pc world what you are charged will depend on your warranty.
If you have the recovery cds try the following the success of this will depend if the hidden sector info in your BIOS being okay 1. boot your pc up with recovery floppy and master cd 1 2. press 'N' to cancel when you get to the welcome to PB recovery program 3. switch to the cdrom drive this is normally Q on PB machines 4. change directory to drivers - type CD DRIVERS 5. type TATTOO /CREATEHSFROMDMI This copies the hidden sector info from the BIOS to the hard drive reboot the computer and attempt the full recovery there are a few other commands, but it depends on the model of pb machine
