Lacie Drive Locked

I took my Lacie drive over to a studio to get some files and when they tried to put data on it, they called me and said the drive was locked. How can I can I get unlocked? Also I took Lacie drive used on a mac, can I use it on a PC without reformatting it?

If your drive was used in the Mac OS environment, it is quite possibly for the drive (depending on ownership) to be locked. Unlocking the drive, is achieved by clicking on the drive once, then going to the top of the FINDER menu and selecting FILE, and on the drop down menu select GET INFO. You can also arrive at this by pressing both the APPLE and letter I key after the drive has been clicked on once to select it. At the bottom of the info column, you will see OWNERSHIP & PERMISSIONS. By pressing the drop down triangle, you will see a second dropdown triangle at DETAILS. Selecting the DETAILS dropdown will allow you to see the padlock, from where selecting that (and knowing a password if there is one-to the drive or user account on the Macintosh being utilized) should unlock the drive and give you further security options. As far as utilizing an external harddrive on both platforms, networking ofcourse works if the drive is stationary. A few other options I could mention would be looking into a solution called MAC DRIVE, a retail software which allows a drive to be read from and written to both platforms, with no issues or having to reformat. Another, is if your computer supports PARALLELS, you can run dual OS and access the drive on both sides that way, depending on how the drive is formatted. Hope this works.

By locked, the studio probably is trying to read your mac hard drive on a PC. There isn't a format that you can share between both mac and PC, however, there are a few utilities out there that claim to allow reading of each other's formats. If it helps, I would network the mac and PC and share the drive from the mac across the network. Then, both could write to the drive.

Here is what LaCie suggests about this issue:- first backup any data you have copied on Wireless Space. You can also backup your configuration: from "configuration" tab of "Support" widget, click "save" button next to "Configuration file", it will download a backup file.
- still in "configuration" tab of "Support" widget, tick the third box labeled "Restore device to factory state (data erased)", or any equivalent quote in selected language, and click apply
- the device will reboot, rebuild hard drive image, then reboot on default state. The issue is definitively fixed
- it is recommended to apply latest update downloaded from LaCie website
- you can restore previous configuration in "configuration" tab of "Support" widget, click restore and select previously downloaded backup file

'not formated'

That's because your Mac was using a file system called HFSX. Windows uses NTFS. They won't be able to talk to each other without some sort of emulation. Check out for a free/open source app that you can install on your Windows machine that will read the data on the Mac-formatted drive. If you are just trying to get the drive to work and don't care about the data, right click on it from Windows Explorer, select "Format", then make sure you set it to use the NTFS file system.

Can an older Lacie drive (2005?) work with an HP tablet?

The native file system for Macs is HFS. If the drive was originally used with a Mac, the current file system on the drive is HFS. Windows uses NTFS and is not compatible with HFS; which is why Windows doesn't recognize the drive as valid.

You can download a data retrieval tool called MacDrive that will give Windows the ability to speak Mac. There is a free trial available and it should be able to help you grab the files off of the drive.

Lacie 320 GB Hard Drive acting as if full when it's not.

Simplest solution: back up the data on the drive and repartition it (which will wipe it). Otherwise it sounds like it could be a problem with the file tree or structure of the drive, the configuration files could be corrupt, some program could have stored temporary files in a hidden place that cannot be deleted without making the program delete them, etc. If you are on a mac, spotlight Disk Utility and use it to repartition. If you are on a PC use the search thing from the start menu and find a program called disk management (or something similar to that, you'll know it when you see it.) external drives are annoying. i kick mine into the wall periodically for good measure.

Lacie drive won't mount

I solved the problem. It was a power supply problem. It seems after searching boards on the net, this is a common problem with the lacie hard drives. Just replace the power if your hard drive is clicking and not mounting. I think many people must be throwing the drives away thinking they are lost when it is just the power supply. Try this first before trashing it or spending a lot of money on data recovery programs/
