When it try's to read disk player it stops! does not recognize external drive

CLEAN THE DVD-PLAYER WITH COMPRESSED AIR.
CHECK THE ELECTRICAL CABEL AND THE DATA WIRE.

It is entirely possible that your external hard drive is failing. I would recommend downloading Seatools for Windows (link below) and run extended hard drive test on it. Chances are if it is failing, it still recognizes within the system, but it is not readable enough for windows to display it and allow you to browse.

There's not much troubelshooting you can do with a failed external disk. power off PC and hd and then disconnect all cables, wait 30 secs, power the PC on, let it boot to the OS, power the hard drive on and then connect. If the drive shows up but you still cannot access it or get weird property readings, it generally means the hd controller has failed. If the data's worth more than $1000, you can take it to a data recovery group like Ontrak or Cherry Systems, but otherwise, just get a new hd and restore whatever backups you have.

you could try removing the drivers from your device manager by going through contol panel or by right-clicking on My Computer and then on the hardware tab. you would find it under cd/dvd rom drives.Just right click and click on uninstall. Then if you dont have your driver disk you might be able to download it from softpedia.com. If you have installed drivers more than once you might be able to roll-back drivers but the best bet would be to just uninstall and re-install the drivers.

Hope this helps

As I understand it the computer recognizes the floppy drive.

Can you read other discs, write to them etc? If not drive is bad

If you can read other discs then your floppy disk is bad

This happened to me as well - i have been reading that it could be the power supply adaptor. If you can try another one - it might solve the problem. The adaptors seem to either be faulty or made to stop working. Great news for us the consumer!!

Try the drive in a different USB port. If it still fails try another computer. If it still fails then it's possible the drive is bad. If the warranty has expired you may be able to find a tech savvy friend to remove the actual drive from the case and hook it up to another computer directly. If it recognizes fine then the case is bad. If it does not recognize the drive then the drive is dead.

You won't be able to retrieve the files on the drive unfortunately unless you use an extremely expensive service. These tend to run in the hundreds of dollars.

Don't know about the MAC part, but an I/O error implies that the either the source file cannot be read or the destination drive will not write. This is usually an indicator of a bad HDD. To check, I would attempt to connect the external drive to another computer. If it still gives the same indication, contact the drive manufacturer about data recovery recommendations
