Question about LaCie Rugged All-Terrain (301017) Hard Drive

1 Answer

I am using a LaCie Rugged, and when I plug it into my Mac, a message pops up saying, "DISK INSERTION: The disk you inserted was not readable by this computer." Buttons read, "Initialize," "Ignore," and "Eject." It does not show up in my Finder or on my Desktop. Please help! Thank you so much!.

When you get this message it usually means that the either hard disk is not formatted correctly, or hard disk/LaCie disk enclosure is defective.

First turn off and disconnect power from Mac and LaCie disk. This procedure may fix problems given by electrostatic charges by draining power completely.
Disconnect Mac adapter and remove main battery if you have a MacBook, disconnect power cord with Mac desktop. Also disconnect USB cable from Mac to Lace and disconnect LaCie power cord.

If the Mac still does not read the disk, test the esternal HDD using a different computer. If the disk works with a Windows PC, then the disk is not formatted for Mac. Use the Mac to format the hard drive. All data previously stored in the LaCie will be deleted.

If it is not possible to format the hard drive, and the disk is not accessed by any computer, then the disk inside the Lacie enclosure is probably faulty. Testing is done taking apart the enclosure and installing the HDD held inside the LaCie caddy into a different enclosure.

When I try to mount my 500gb minimax on my mac mini, i get this message: "Disk Insertion, The disk you inserted was not readable by this computer." When i click on "initialize" and then...

Unfortunately, that does not sound good. What format is your drive? (Mac OS extended/ FAT32/ NTFS/ etc). If it is a mac format you could try something like drive genius to hopefully be able to get it working again. If it is a different format you could try G-parted or there are a lot of good tools on ultimate boot cd (although they are kind of geeky and hard to use).
Unfortunately if it is starting to die, and the info on it is really valuable to you, your only option may be able to send it off to a data recovery place, but they are VERY expensive (sometimes $1000+ and it's not even guaranteed to work). I wish I had better news.
If this was a help please give me 4 thumbs up as I am trying to build up my rep on this site!

First, connect the hard drive to the computer. Go to the search bar in the top right and search: Disk Utility. Then select your hard drive (not a subsection, the actual hard drive). go to the First Aid tab, and click "repair disk".

If this does not fix it, then I am afraid that your drive is dead.You may have abused the product in some way (dropped it, dropped it while it was on, bumped it, didn't drag the drive to the trash can, etc).

if the option is available in disk utility, run First Aid.
Second option will be to run a third party partition repair utility if you have one available. If it does not fix the issue, go for a data recovery software. Some have a free trial that allows you to verify if the data on your drive is retrievable with their software before you buy the complete version to recover the data.
If the software does not do it, you can try connecting the hard drive inside the enclosure directly to the computer, but take note that:
-Taking the drive out of the enclosure will void the warranty
-If any electrical damage is present on the hard drive, it can damage your computer, so unless you are competent with electronics and can recognize healthy components, do not connect the drive to a computer.

If all those have failed, you will have to contact a data recovery center for a complete diagnostic.

Make sure that you do not format or initialize the drive.
If your data is ever available during the process, copy it to two other devices/computers to prevent the risk of losing them again.

Disk is not readable by the computer.

Try a different "data" cable between your computer and the external disk-drive.

Try connecting the unit to a different computer.
If it fails there, then the unit itself has a problem:
* the USB-to-disk-drive adapter (inside the casing) has failed;
* the disk-drive (inside the casing) has failed.

Disassemble the external unit, and remove the disk-drive. Connect it as a "slave" disk-drive in some Apple Computer, to see if the data on the disk-drive can still be accessed.

Check with LACIE, to see if their "warranty" is still valid, or if it has expired.
