Question about LaCie Ethernet Disk Mini, 500 GB Hard Disk Drive with Gigabit Ethernet & USB 2.0 Interface, 7200 rpm... IDE Hard Drive

1 Answer

Disk no longer powers up

This is actually an Ethernet disk mini 320gb, but there didn't seem to be a matching category for that.  
Two days ago, while trying to access the drive it spontaneously switched itself off.  Attempts to restart the drive caused the blue LED to flutter for a second or so, but the disk did not sustain a powered state.  I unplugged the disk and the brick converter for a day or so.  Now when I plug them both in, the blue LED doesn't flicker at all anymore.  
The green LED on the brick is steady on.  Prior to the failure, there were no telltale sounds of disk failure.  I don't think it's the disk.  I think it must be something else.  
The original configuration had the disk connected to an Airport Extreme via the ethernet port.  I've tried different arrangements with the USB cable, but nothing changes the appearance that power is not reaching the disk.  
Any Thoughts?

    Thanks for your help, I have a little more information. I'm going to get the multimeter out this afternoon to test the output. In the meantime, about the drive and its enclosure:

    The computer I have most ready access to is an iBook. Would I have to find a desktop computer to fully diagnose this problem? I mean, is there an IDE to USB, or IDE to firewire adaptor that could do the same thing as installing it inside a desktop? I suppose I would also have to find a way to power it, though.

    Also, I am wondering about another possible issue. As I recall, The FAT32 file structure could not handle files over 4GB. I needed something that could because SuperDuper puts all backups into one gigantic disk image. So the manual said to reformat to EXT3, but that the drive would be inaccessible by USB, only ethernet would work. How does this affect me? If I took the disk out of the enclosure and hooked it up via IDE, would it even recognize the drive? Or do I need to get a new enclosure with an ethernet port, which seems to cost about 2/3s the price of a new NAS.

    The more I think about this, the more I hope it's just a bad adaptor!

    Thanks for your help!

    wondering how this worked out for you. I have an ethernet big disk and the the drive will not power up. Have had two different power supplies sent from lacie under warranty. first one worked. then it died after a month. second power supply sent from lacie does nothing to remedy the problem. drive is under warranty for repair, but all data will be lost if repaired (according to lacie.) So i would rather void the warranty by hooking up via IDE or SATA cable in the tower then lose the data via their repair. Wondering if your hookup worked or if you tried the recommended solution?

You may have a faulty power adapter, you need to check if it has +12volts & +5volts with a multimeter. You might be able to borrow a power adapter to test the drive before you pull it apart.

To test the hard drive.
Remove the hard drive from the case and connect it directly to the IDE cable (or SATA cable) and the power connector inside your computer. Depending whether the drive is on a IDE cabe on its own, then the jumper can be set to either Master or Slave.
If the drive is on the same cable as your existing hard drive then the 320Gb drive should be jumpered as a slave drive.

When you boot up your computer check the BIOS to see if it detects the 320Gb drive, if OK then let it boot up into Windows.
If you then click on My Computer you should see your C: drive as well as your 320Gb drive (might be D: drive). You should be able to Explore/view the files on this drive, if so the drive is OK then the power adapter or the hard drive USB box is faulty.

    There are IDE to USB external hard drive enclosures, they mostly come with a power supply adapter. There 21/2" laptop hard drive enclosures usually without power adapters and 31/2" PC hard drive enclosures with power adapters.

    If you wish to copy and read files between MAC and Windows operating system then I suggest the hard drive should be formatted in NTFS, you would need to carry out this on a Windows PC. The MAC can read and copy Windows files but Windows cannot read MAC files. If you only want to use it only on MAC platforms then format the drive with MAC OS.

    Ater you install your hard drive into the USB external drive case, it can be plugged into either a MAC's USB port or Window's USB port, it should see the 320Gb drive as another hard drive on the computer's system. Try using a Windows PC running Windows XP or Vista to test the hard drive using the USB adapter/case. Don't forget that if it was formatted with a MAC, the Windows PC won't be able to read the hard drive.

    Try to borrow a adapter, if you have to buy one and the hard drive was dead, then you can buy a new hard drive and fit it in the adapter/case. I find this more useful than a NAS drive, because you can take this USB drive with you and use it on any computer.

SimpleTech SimpleDrive Pininfarina 320GB, I just need a driver for the external HD. I have moved and I cannot find my disk for my computer. OS is Pro XP I am unsure which SimpleDrive version you have, but if it's the regular (not deluxe, mini, or 3.0), it should be the first driver on that page, assuming that Windows XP doesn't install the drivers itself when you plug it in.

I have the Lacie Minidisk Ethernet 500 GB that contains all my house PC backup. I both an USB Minidisk Lacie (1 GB) in order to use MySafe feature but it never worked.

Hello Elio,

Use MySafe to back up the files stored on the Ethernet Disk mini Home to an attached USB storage device. This way, if files on the Ethernet Disk mini are damaged or accidentally deleted, you can restore them to their original locations.
There are three main steps to using MySafe,Connecting an external USB hard drive,Backing up files to the external USB hard drive,Restoring files to the Ethernet Disk mini (if necessary)
Before you can back up files, you need to connect a hard drive to your Ethernet Disk mini via the USB port on the back. Use a hard drive that is USB 2.0 compatible.
While connecting an external hard drive make sure your Ethernet Disk mini is turned on and connected to your network.Turn on the external USB hard drive.Connect the external hard drive's USB cable to the USB port on the back of the Ethernet Disk mini, just like you would connect the external hard drive to your computer.Confirm that the drive is properly connected. Log in and click on the Administer HipServ link. Click on USB External Storage under System.
To back up files, navigate to the file or folder you want to back up to the external hard drive and click on the disk icon in the "Backup" column of the file list.When you back up files to MySafe, the Ethernet Disk mini duplicates the file path in MySafe so that everything you back up is organized in MySafe just as in its original location. So, if you copy a file from MyLibrary, a MyLibrary folder will appear in MySafe, with all folders leading to the backed up file.

Always click the Safely Remove Drive button on the USB External Storage before unplugging your MySafe external hard drive. Wait for the interface to change and for the Use Drive button to appear before disconnecting the USB cable from the Ethernet Disk mini. Failure to safely remove your external hard drive before disconnecting the USB cable can cause data loss and/or damage the drive. Always use the Safely Remove Drive feature when disconnecting an external hard drive.

Lacie ED mini v2 won't start up.

I had the same problem twice, but it was the power adapters each time that were causing the problem. It wasn't the unit itself. Lacie replaced the power adapters and it worked fine.

I have a 320gb WD hard disk and it was working normally but few days ago when i plug it, it could not work. ( the light is on but there is no spinning sound)

Seems to me a defective interface circuitry.
These devices have a USB-to-SATA interface inside their enclosure. If you can find another enclosure with a similar interface (or buy a new enclosure), disassemble your hard disk enclosure, get the hard drive out & attach it to the interface in the other enclosure & see if it works.

Another possibility is that the interface could be fine, but the hard drive itself died. To test this possibility, try attaching the hard drive directly to a PC. Since the hard drive is a SATA drive, you will be able to do this easily.

Disk will not power down. Has vanished from my computer, but router IDs it.

Well according to LaCie's support when the power button is failing to work and the fan becoming inconsistent it is due to the power supply failing.

This is because the OS controls the power button and if it cannot boot fully because of a power problem, then functions of the drive are turned off, including the power button.

They are going to send me a new one.

Lost Connection

Most problems I have had with Lacie NAS have been due to duff power supplies. Seems odd that it should make a difference but it does: the power supply seems to make hte connection hang which  you then can't reset just by turning off hte power.
