Put disks in but does nt recognize them. Blue light stays on permanantley

Check for low brake fluid level or park brake handle/pedal slightly engaged

turn signal switch internal short replace switch

Please run disk utility and see if you can find it physically first.

If you do, please format it.

If you don't, first connect it by using very short usb cable into back of your mac. (Sometimes, usb ports in front or monitor don't provide its power fully.)

I hope it helps.

I think I can help here:
Make sure your headset and phone are charged before doing anything else. The blue light on your headset will come on when it is charging, and will shut off when fully charged.
To put your headset in pairing mode, make sure it is completely off first (no blinking blue light). Then hold down the Call button for 6-10 seconds until the blue light stays on. (It will likely flash once and shut off, but keep holding until it is all the way on and stays there!)
From there, go into the settings on your Droid 2 and access the bluetooth connections. Do a new scan for your headset if you don't see it listed, pair, and connect!

There's a fault inside. If you're lucky the fault is in the connector plate so removing the disk and putting it in a pc will allow you full access to the data. If when you do that the disk is still not recognized , or worse, it messes your pc, then the disk is dead and the data is lost.

reboot the system and try to insert disks if it doesnt work go to a technician first solution worked for me

I had the same issue after playing Call of Duty 4. Just wouldn't read any type of disc. Spoke to Sony sent a new PS3 out the very next day. My brother in law a week later experienced the same, again Sony sent new PS3 out. I think theres a problem with it, and thats why Sony just replaces them with no questions asked to avoid bad publicity

I have one of the Sans disk also. I find its the connector itself. I really like the Sans disk, but it not working is a real pain. I find if I'm a little more gentle, like inserting it slowly, it seems to be recognized more often.

Same issue with my 500 GB TFD500U16. A little more description is that my PC is detecting the power when turning on the drive and the HDD itself is spinning up. Also the Blue light that normally indicates HDD activity by turning Red no longer shows activity but just stays Blue. This indicates that the data side of the HDD is not seated properly. Since mine is out of Warranty, I took it apart and found this to be the exact case.
! ! ! ! Please perform this at your own risk ! ! ! ! Especially if your warranty is still in effect! ! ! By loosening the HDD mounting screws inside that will allow the connection to seat properly and data to be seen.

Your PS2 is definitely broken. Either send it in to Sony to be repaired or buy a new PS3. Bummer. Sorry to hear about this.
