Re: Big Disk disapeared

Before anyone can help you with this they would need to know the operating system you using and possibly the hardware your using, and anything that may have changed, moving equipment changing anything power outages unplugging anything, anything that happened before the problem occured, also does the disk make any new noises or is it not spinning, put your hand on the case while its off and turn it on you should notice a slight vibration start this means its at least spinning, also are the led's(lights) illuminating as they did before or are they flashing or an odd color, also how are you trying to access the drive, from a file manager(finder/explorer/etc.) or an application(imovie/windows movie maker/etc.) and where was the icon normally, if using a mac it should normally mount directly to the desktop by itself, in windows it will appear in my computer after it has mounted, open the device manager and check to see if windows can see it at all....right click on [my computer] and select [properties] then click on the [hardware] tab then click the [device manager] button, expand the usb list or whatever type of connection is used for the disk, and see if it shows up also check in the removable storage areas and the hard drive list.

Re: Big Disk disapeared

Posted Oct 13, 2006 - It's not the drives that fail, it's the power supplies... They fry after about 3 months-1.5 years. LaCie sells replacements for about $16-$20, depending on the model. We have over 20 of these drives, and here's how you know: the drive spins up, then down - it tries to mount, data transfer will freeze, etc. Just put another power supply on it, and 9 times out of 10, it's fine. Of course, any drive can fry on you, but these have proven to be extremely reliable under some of the hardest use imaginable.

I think the problem is because mounting problem of the logical drive .In this case to access your data in the drive you just need a macbook hard drive recovery tool .Remove the drive from your pc install the drive in some other mac pc and start it in target mode .Install this recovery tool and start recovering files but save it in different healthy drive .I am suggesting this tool because it works good for my missing partition problem.But purchase the full version to get good results.The demo version link is here...

My lacie mounts on the g5 but when i click it, it doesn't open.

It would be a good idea to look at the Mac system log so from a v bad memory Apple (top laft hand corner) then about this Mac then System Profiler then Logs and take a look and see what errors you are getting. If this doesnt give you any clues my advice with external disk problems is where possible to remove the disk from the enclosure and install it in the Mac. if you can, THis will eliminate the USB cable, interface, and box. See if it mounts then. If it does run disk utility to double check it but get your data off first onto the Mac. Hope this helps....Mark

Macintosh computer not recognizing the LaCie external hard drive

1. If you have another firewire device test this device with the same firewire cord you are currently useing for the LaCie. (if there is no reasponse form the other device then it is the cord it's self) If not then 2. Check the Leads on the back of the LaCie where the firewire plugs in if the copper looks tarnished use a ear swab dipped in Lime Away or CLR to clean it then wait for it to dry and try the cord again. 3. if these physical connections are in good connection with each other and the firewire in port on your computer and on the LaCie are good then. Run a "Permissions" verify and repair through the disk utility program on your Mac with the LaCie turned on and plugged in.
FINALLY if none of these options repair the LaCie you may have to open the LaCie up and check to make sure the soldering from the firewire to the chip set is still in tact. I hope this helps Happy Macing.

Trouble seeing my lacie drive possible mounting issue

Not sure if this is the exact same issue, but I couldn't get the drive to mount with different connections, etc. The problem turned out to be the power adapter. If you've got the same kind of adapter on another drive, switch it out and see if your drive shows up. Good luck.

Lacie Big Disk -High Speed UBS 2.0

If all you need is to get the data off your HD at this time and work later on fixing it. Open "IPConfigurator" and it will find your Lacie. At this point you should be able to open it via an internet browser, select HTTP, enter username and password. Then select the item and it will open/download and you can re-save it or view it from the internet.
