Light doesn't turn blue at all

What burning software/version are you using?

Have you tried the hard drive outside of the enclosure? Maybe it just isn't compatible with it. Else something with the connector could be broken

There are multiple possible reasons for your problem:
1. virus
2. hard-drive malfunctions
3. OS malfunctions
4. memory failure

Try to install an antivirus and do a deep scan. You should pay attention to a boot sector virus.

If this doesn't help, do a back-up of your data, format your hard disk and re-install a fresh OS.

If this doesn't help either, try changing the RAM memory.

If that doesn't help either, it means your hard disk's boot sector is damaged. There are solutions for this too, but I think there is a big chance you won't get to this point.

Hi Angela ,
You' re probably facing a power or usb issue . Consider opening the enclosure ( will be lost , i presume ) and placing the drive in an external usb box ( available in any computer store starting from 20 $ ) to be reconnected to your pc . If this doesn' t help , it means your device is dead . There then still is a small opportunity to recover the lost data by using a recovery software like Recuva ( free ) or TenorShare Recovery ( payable ) .
This should help you solving your issue .

clicking noises coming from the hard drive means that the hard drive has died remove the drive and try another to see if the computer boots up.

First make sure usb cable connected to harddrive is working fine. try it in different usb ports. Press windows key +R key so you can see run then type in run "devmgmt.msc" then press ok so you can see device manager uninstall all usb drivers then it automatic install usb drivers. then check. Also you need to change registry for that type in run "regedit" then press ok then you can see registry editor then locate below key. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11 CE-BFC1-08002BE10318} And remove upper filter and lower filter.Then restart computer then check. Also locate the below key and make sure it's value is 3 not 4. HKLM\system\currentcontrolset\services\usbstor make sure start value is 3 not 4. Let me know if you need further assistance.

well ur drive is on offline mode... go to disk management and make it online and assign it a drive letter

It may require a driver from Simpletech to function.

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.

typical of external drives overheating.
i sell external case with fan at my store.
