Try attaching your Maxtor drive, to some other healthy system and see if the drive is detected there. If not, then the only way to gain access to the data on your Maxtor drive is to use a recovery software. Try FAT Data Recovery Software
. You can use the demo version to see whether the software is able to recover your files or not. Never install the recovery software on the drive from which you want to recover data, also never save any data on the same drive from which you are recovering data. Hope this helps you!
