Lacie 1TB External Drive flashing blue light, not being found

I've had the external drive for less than a year. One day I turn it on and the blue light just flashes and the external is making weird noises. I connected it to my Mac OS and it couldn't find it, I also connected it to my Macbook pro and I had the same problem. Does anyone know how to correct this, or have I lost everything on my hard drive? Please help!

SOURCE: LaCie 1TB external hard drive is not registering

Hello

Okay , so there are some steps to figure out what is wrong with your external.

Firstly , if your computer makes a sound when you plug in your external , go to Start-Control Panel-Administrative Tools-Computer Management-Disk Management , and see if your external drive is listed here with your local drives. If it is listed , right click on the drive and change the drive letter to make it appear in "my computer".

If your drive does not make a connection sound when connecting to your computer and also does not show up , please follow the next step.

Remove the hard drive from the casing if possible and install it in your computer case or another external case.If the drive works , the problem is with the casing and you can ignore the drive.

Now , if the problem is with the casing , there are still 3 possibilities.

  1. The USB cable between the drive and the computer may be damaged.
  2. The circuit board which connects your drive to the interface of the external may be blown.
  3. The power supply (if applicable) may have a blown transformer.
The latter is the easiest to diagnose , does your external light up at all when you plug in the power? If not , then this is probably your problem. On the bottom of the adapter is a label which you will be able to use to have a new adapter made at your local electronics shop and this will cost about $30 max. They will also be able to test the adapter with a clamp meter to see if this is really the problem and this should be free.

The second component you want to test is the USB cable. If you have a printer , swop out the cables and see if your printer functions normally. Most externals use the same connector so you should be able to test it in this manner. If the cable works go on to the last step. If the cable is defective , replace it with a new one which you can find for about $10 at most electronics and chain stores.

The last component to test is the circuit board. This is a bit of a grey zone as you probably won't be able to spot the blown component unless it failed really badly. With the casing already opened , locate the external's circuit board and check to see if you have any blackened components or fluids leaking from some components. If all the other components of the external worked perfectly , then this is the faulty part. It is not really economical to replace the circuit as most of the time it is out of production by the time you need to replace it and it still costs a lot even if it is available so if your drive is working perfectly when connected via sata or IDE on your computer , the best is to buy a new casing and place your old drive in the new casing.

A casing costs about $50 and you could get it at most tech shops and big chain stores like Best Buy.

I hope this solves your problem and please reply if you need more help.

Kind Regards
Andrea

check wires connecting them together first, ok?

then, turn off the LaCie, connect to your MacPro, and then turn on the drive..

that should show as a mounted drive.

Lacie Case Only lighting up when HD is disconnected


I had the same problem with a 1TB hard drive. The fault was caused by the casing being knocked from the computer and falling onto the desk. If the hard drive hadn't been powered up it would have been ok...
I removed the hard drive from the casing and fitted it into my computer as a slave drive, hoping to access all the music and movies stored in it. No go .. But, it's worth you fitting your hard drive as a slave and trying the same. It's worth a shot.
I took the hard drive to a computer market here in China, where I work. These guys take hard drives apart to fix them, if possible. They couldn't fix my hard drive as it had been powered on when it fell ..
However, I bought a new desktop hard drive and they were able to transfer 95% of all things from the old hard drive to the new one. The cost of transferring from the old hard drive to the new hard drive was the same as the price of the new hard drive. That specialist service doesn't come cheap ... but it can be done. I paid simply because I didn't want to lose what had taken more than a year to download.
Try fitting your hard drive as a slave to see if you can access the information on it. If not, a new hard drive and the cost of transferring your music from your old hard drive may be the only course of action left open to you

I have external hard lacie it work normal before two day but now it cannot detect


Just contact www.lacie.com great support. their answer for my drive was to upgrade the drive version and to reboot the drive. Maybe the last thing is enough. For me it worked.

If necessary update driver http://www.lacie.com/nl/support/drivers/driver.htm?id=10156

Follow the procedure below to reset the Network Space to factory defaults:
  1. Move the power switch to the OFF position. Wait for the drive to shut down.
  2. Turn ON the drive.
  3. Within about 3 seconds, flip the switch OFF and On several times.
  4. Immediately turn it ON
If the light flashes quickly, the unit is resetting itself. Attempt to connect to the drive again after about 1 minute using the default username and password (by default, they are both admin.)

Lacie 1tb external hard drive into ps3 is not regconised


I have the same issue, however with my verbatim 500g its ok. i believe it is because the lacie is a desktop external and therefore is compatable with windows xp and 7 alone.
Verbatim is a "portable" external hard drive which makes it compatible with several different systems. I would suggest returning it, I just formatted my old verbatim harddrive and set up mediaasharing. Through my router. You can actually route the lacie harddrive by going to my computer and right click the icon. Next go to share with; advanced settings and allow all. Then when you turn your ps3 on search for media servers... I would suggest to google media server for ps3 to get it all seet up. GOOD LUCK
