The disk is not readable - Sony PlayStation Portable (PSP) Console

sometimes you get this problem if you have changed software version what software was you using before and are these zip disks off your comp originally or from another sourse you could try reinstalling the software that came with it or if dont have software you should be able to get it off the net hope this is some help ...............................................

It is possible that there are errors on the floppy disk or the disk was formated using a format that is incompatible with the current operating system. If the disk is readable on another system, the best solution would be to copy the files onto a portable USB flash drive, then reformat the floppy disk using a filesystem that is readable on the desired computer.

Perform a compatibility check of the Disk DVD whether the computer is capable of reading the media type. Usually, disks movies are readable on DVD players, computer game Disks on computer drivers, and game in Disks on game consoles. Observe the disk to acquire the detail requirements of what type of decoder device is capable of display.

have a read here Fix the disk you inserted was not readable by this computer on Mac

Try a different "data" cable between your computer and the external disk-drive.

Try connecting the unit to a different computer.
If it fails there, then the unit itself has a problem:
Either:
* the USB-to-disk-drive adapter (inside the casing) has failed;
* the disk-drive (inside the casing) has failed.

Disassemble the external unit, and remove the disk-drive. Connect it as a "slave" disk-drive in some Apple Computer, to see if the data on the disk-drive can still be accessed.

Check with LACIE, to see if their "warranty" is still valid, or if it has expired.

The Disk inserted dose not work

I used a card rescue software.

You need to download the SATA driver for your hard drive to a readable disk and reinstall xp and when the xp installation ask if you need to install 3rd party driver tap F6 and load the driver from the readable disk you put the drivers on,(This cannot be done on the same drive that contains the xp install disk since removing the disk would stop the installation)I recommend a usb drive,But you will need to enable boot from usb device in the bios first.Or if you have a floppy drive That would work too.
