Question about Ultra 1 Bay USB 2.0 External Drive Case

1 Answer

Saying disk not readable

ON MY MAC 10.4.9 TIGER, I AM USING THE ULTRA MINI DISK EXTERNAL DRIVE WHICH IS CONNECTED WITH A USB. I ALSO HAVE A M AUDIO INTERFACE CONNECTED TO THE MAC BY FIREWIRE. PREVIOUSLY I WAS RUNNING THE MUSIC TRACKS FROM THE DRIVE WITHOUT A PROBLEM.THEN I WANTED TO RECORD ON THEM, SO MAC SUPPORT SAID TO TAKE OUT USB AND DAISY CHAIN THE MINI EXTERNAL DRIVE TO THE AUDIO INTERFACE THROUGH FIREWIRE WHICH GOES INTO THE 1814 PORT OF THE INTERFACE. THIS WORKED RIGHT AWAY AND I WAS ABLE TO RECORD.THEN THERE WAS SOME LOUD FEED BACK, AND SAID THAT THE DRIVE DID NOT HAVE ENOUGH SPACE TO SUPPORT IT.BASICALLY, IT CRASHED. AFTER THIS THE DRIVE WOULD NO LONGER READ THE DISK, EITHER WAY VIA USB WHICH ORIGINALLY WORKED FOR DAYS, OR THROUGH THE DAISY CHAIN OF FIREWIRE TO THE AUDIO INTERFACE. HELP

You could try a repartition / reformat, if the drive is detected at all, or you could try running scandisk/disktools, to try and recover / repair the TOC/ FAT

Unable to read external HDD after plugging it to a Mac (previously it is readable via a Windows PC)


Chances are it was formatted as NTFS format by the PC which is not MAC compatible. You will need to reformat the drive in HFS format if you want it to work as a MAC disk only or in FAT32 format if you want to read it in PC and MAC machines.

Tip

Formatting an external hard drive with Mac OS X's Disk Utility


Formatting your new external hard drive is not as difficult as you may think. In fact, you don't even have to be a computer techie or uber-Mac geek to perform this procedure successfully.

The tool you would use, to format your drive within your Mac OS X system, is the built-in utility application called Disk Utility.

Disk Utility is Apple Inc.'s defacto utility application, for performing disk related tasks within the Mac OS X volume.

From creating new images, to burning CDs and DVDs to formatting hard drives, Disk Utility performs well enough to keep not only your Mac OS X volume on your hard drive error free, but keep your hard drive healthy and error-free as well.

I could go on in detail, admirably describing more features of this versatile Mac OS X tool, but the purpose of this FixYa tip, is to show you how to easily format your external hard drive. So that is where I will take you now.
-----------------------------------------------------------------------------------------------
There are generally two formats in Disk Utility that you can use to effectively format your hard drive.

Mac OS Extended (Journaled) - if you want a Mac readable hard drive only

MS-DOS (FAT 32) - If you want your external hard drive to be read by both Mac and PC.

-----------------------------------------------------------------------------------------------
--STEPS FOR FORMATTING YOUR HARD DRIVE WITH DISK UTILITY--
-----------------------------------------------------------------------------------------------
• First, make sure your external hard drive is connected securely to your Mac and is turned on.

•Next, from your desktop, click anywhere on a blank space on your desktop. Now you should see Finder listed near the Apple menu icon.

• From the Finder menu, click on Go, then Utilities from the
drop-down menu. This will take you to your Utilities* folder.

(*You can also get to the Disk Utility application via Applications > Utilities folder)

• Now, locate and launch the Disk Utility application.

When Disk Utility opens you will see a left side window, which will show
all connected hard drives and optical drives. It is here that you
should see your external hard drive listed in that window.

• When you locate it, simply select it and then select Partition
from the tabs on the right hand side.

• Change the Volume Scheme from Current to 1 Partition

• Make sure to provide a name for your new external hard drive.

• Select Mac OS Extended (Journaled) from the Format
drop down menu, for a bootable Mac only external hard drive.

• Or select MS-DOS from the Format drop down menu, for a bootable Mac & PC external hard drive.

From there, click the Options button, located toward the bottom of
your window.


This will open a partition scheme selection window as seen in this screen shot:

• Select GUID Partition Table for bootability on a Intel processor based
Mac.

• Or select the Apple Partition Map for bootability on a PowerPC based Mac.

• Click the OK button.

Finally, click the Partition button and allow Disk Utility to format your new external hard drive.

When this process is complete, you now have a newly formatted, ready to use hard drive.

Believe it or not, this process can be completed faster than you think.
Using this method with Disk Utility, I was able to format my new 1TB Iomega USB external in less than 20 minutes.
-----------------------------------------------------------------------------------------------
Final Note:
I used the external hard drive as the focus for showing you how to format and prepare your hard drive for use on your Mac, but this feature can also work with internal hard drives as well.
-----------------------------------------------------------------------------------------------
For more information about some of the disk repairing features of Disk Utility, here is a great support link for this nifty and quite effective Apple utility for the Mac OS X platforms:

I USED MY FREE AGENT DESK EXTERNAL DRIVE 500GB ON MY MAC GOT A NEW DELL AND CONNECTED THE DRIVE...IT SHOWS UP BUT I CANNOT OPEN IT PLEASE HELP


if you still can see files on the Hard disk from MAC, then the reason of being unabe to explore your file from MS windows is that your hard was initialized by MAC with a format that windows cannot read.
move your data from external hard disk to your MAC then format your hard disk from windows OS with FAT32 format .this format is readable on both MAC and WINDOWS

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.

When i try to run a disk it says the disk is not formatted do i want to format it now. the disk has information on it so it has to be formatted .


It is possible that there are errors on the floppy disk or the disk was formated using a format that is incompatible with the current operating system. If the disk is readable on another system, the best solution would be to copy the files onto a portable USB flash drive, then reformat the floppy disk using a filesystem that is readable on the desired computer.

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:
Either:
* 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.

Mac not recognizing External Western Digital HD.


the problem is that your western digital operates using the NTFS (New Technology File System) which is the standard file system of Windows. Apple macs is not interopable with native NTFS therefore you need to install a read-write NTFS file-system driver on your mac.

an excellent free mac NTFS driver can be found here-

download and install the software then restart your mac.

USB hard drive not recognized by Mac and by PC


Does the external drive work when connected to some _other_ computer? (Friend? Office? Home?)

It could be a failure either in the "hardware" inside the external-case (the USB adapter & interface)
or in the disk-drive "inside" the external-case.

So, a qualified technician can open the external drive, remove the disk-drive, and connect it directly to a computer, to see if the files can be "directly" read from the disk-drive.

If not, then you should search online for a "data recovery" service -- they are expensive, but they physically repair a damaged disk-drive, just long-enough to copy your data to another disk-drive.

LaCie 500GB external will not show up on mac desktop. Blue light on, whirrs as if working but no icon on desktop (not mounted)


Did you format the drive using Disk Utility? Open "disk utility" from the dock icon or applications/utilities folder. Click the drive name on the left side of the disk utility window. click the "partition" tab in the window, next click the "options" tab and select GUID Partition scheme, or any Mac compatible scheme, read each explanation of the schemes. Name and resize your partitions, click apply. This is how it works running Leopard, not positive if the same applies to Tiger. I hope this helps you
