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.

Try connecting the Lacie to another computer, if it doesn't work then the hard disk may need to be formatted using Disk Manager. I suggest you format as a primary partition in FAT32.
If it doesn't work then it is possible that the hard drive in the Lacie has failed.
To test the hard drive, remove it and connect it to an USB hard drive adapter and connect it to a working computer's USB port. If it deosn't detect it as an external drive and you connot open folders and files then it is faulty.
You can install a new hard drive in the Lacie and then format in FAT32
There are companies that can recover data from faulty hard drives BUT it will cost you an arm and a leg for their services.

SOURCE: Macintosh computer not recognizing the LaCie external hard drive

First thing to check is whether the Mac recognises the LaCie hardware. Go to the Apple icon, and select 'About this Mac/Computer' then more info, which will launch System Profiler, check the FireWire section under Hardware to see if your drive is listed. Assuming it is, and that the Disk Utility program doesn't see the drive, then you'll need a Disk analysis program like 'Drive Genius' or a recovery program like 'Disk Warrior'
Should your drive not be seen under the FireWire section, you have an interface failure on the LaCie, which isn't terminal, you'll just need to put the drive in another HD case and then read the data. Reply to this and I'll try and give more help depending on the results you get in System Profiler.

SOURCE: cant delete files off external

Hello,
this sometimes happens when you delete files partially. Deleting file normally will send it to the Trash (MAC) or Recycle Bin (PC) . The file is not really deleted at that point. Make sure to empty the Trash or Recycle Bin and the space should be freed.
If this does not work, copy all needed files somewhere else, then format the drive.
Regards,
