Question about LaCie Big Disk External USB 2.0 1TB Hard Drive

3 Answers

Drive is on, won't mount, buzzing

Hi there,

My LaCie Big Disk USB 1TB drive isn't working properly, and I'm wondering if all hope is lost. About half an hour ago, it would still mount on my MacBook Pro, but I just couldn't write any new data or read any of the stuff on it. I would get the spinning pinwheel, and then the drive would disappear, saying I removed it unproperly, even though it was still connected to the computer.

Now, however, it won't even mount anymore, and it's making this buzzing noise every few seconds.

Ugh... I have about 900mb of really important data on this (I'm a filmmaker and I use Final Cut Pro often), and I'm wondering if there's anything I can do to remedy the situation?

Thanks so much!

Warmest regards,
Stephen

It does not sound good, the hard drive may be faulty or even the drive enclosure could be faulty.
Try thr following:-
1. Take the LaCie drive and connect it to another MAC, if it reads the drive, your in luck.
2. Dismantle the drive case and remove the hard drive and reconnect it again (a few times). The drive may need reseating to make proper electrical connection. Test it in your MAC.
3. The LaCie case could be faulty, remove the drive and insert it into another working LaCie drive case. Test it in your MAC.
4. If the hard drive is faulty, there are hard drive data recovery companies that can retrieve your data, but it will cost you an arm and a leg for their service.

In future I would not rely on a single device for backing up important data. You should get 2 LaCie drives or a dat tape drive plus a LaCie drive and/or burn the data on BlueRay disks.
You should also protect your computer and devices against lightning strikes, power outages/blackouts and power surges with an UPS (uninterruptable power supply), especially when you are editing, burning, copying/back up your data.

I had a very similar problem with my LaCie drive. It turned out that it was power related, and the problem was solved by replacing the AC adapter.
The drive was working fine, but one day stopped mounting. I tried it on other Mac machines, and Windows machines, but it would not mount. All the power lights came on, and I could hear the drives making some noise, but nothing happened when plugged in.
After a few tests, I noticed that the drives didn't sound 'right'. They made noise when turned on, but didn't sound like the platters were not spinning up.  I held the drive in my hand the next time I turned in on, and noted that there was no notivable movement.  The drives had power, but were not spinning up.  In my mind, this meant they weren't getting enough power. I had the drive open at this point, so made sure there was no corrosion or damage around the AC port, which there wasn't.  So I pointed my finder at the power supply, the AC acapter for the drive. I had another LaCie drive in the office, so I grabbed it's AC adapter and cord.  I made sure that it have the same voltage configuration (check diagrams and spec printed on the adapters) and made sure I wasn't using an adapter with more current  (Amps). I plugged it in, the drives spun up and mounted to the desktop on first attempt. I was so releived that I didn't lose the 1TB of data.  It was actually a drive we used for transporting large volumes, and I hadn't yet backed up to our RAID.  I assued it was damaged in commute, but didn't give up until diagnosing fully. I rarely use data though, and it's usually human error (accidental deletion or dropping the drive). Outside of that, problems are generally repairable, and data recoverable, without having to spend the big money.  Be thorough, diligent and creative in your testing before declaring a loss.

Greetings,

I would try another USB connection/bus. For example, have one drive on the front ports of your system (if it has them) and then the other drive on the back ports. Additionally, if both or either drives have an option to include a power adapter or a second usb connector for power, I would highly recommend that those are used.

That may be "the clash" that we talked about in the clarification section.

Hope that helps,

My "t " bird hard drive fell onto floor from about


The '1TB' device is 10 to a large power.
The '930GB' is 2 to a much-larger power.

Since '1GB' is 1,073,741,824 bytes,
multiplying 930 times 1,073,741,824 is equal to 1TB.

So, your device is 100% empty -- all 930GB are "free" space.

LaCie Big Disk Extreme 1TB Hard Drive - continuous beep, no power


Hi, Lacie isn't very forthcoming with beep codes but it definitely means one of the two. You can try moving the hard drive into a new enclosure, if it works it was the enclosure, if not the HDD. Hate to say it but warranty on these drives is a moot point the moment unique data is stored on them as you can't even diagnose the problem properly without voiding it and no drive manufacturer will waranty data. If you have no unique data and it's under warranty, send it back. If you have unique data on it that you value, take it to a local computer store and have them move the drive to a new external enclosure and test it. If it works, you're done. If it doesn't, you've confirmed that the HDD is faulty and you will need the help of a data recovery Pro. If the latter is the case, reply by commenting here with your location (country, state city) and I'll recommend a closeby facility for you. Chris
