Iomega 500 gb external drive no longer mounts on mac os x tiger
I've been using this external drive for several months and have data backed up on it. So, one day the icon does not show up on my desktop at all. I tried using the disk utility but it does not show up on that either. Weird thing is that is shows up as a USB device in about this mac. It appears that the diagnostic capability of the computer recognizes it but I cannot access it to use the disk utility or access the files. What should I do?

Re: Iomega 500 gb external drive no longer mounts on mac...
Ok I have had probs like this before. try plugging it in to different usb ports. also try another cable is it usb? or fire wire? I have had issues with several items doing the same thing I just try different cables and different ports and keep un plugging and plugging it back in. usually either a dif port os cable solves the issue. also try connecting it to another pc and see if u can access it. If you can access it from aonther pc that you have in your home or access to all the time I can tell u how to have it hooked to that pc but be able to access it from the origional pc that you had it hooked to.

Re: Iomega 500 gb external drive no longer mounts on mac...
I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and OTHER devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port
If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE. Any exclamation marks by hardware need fixing before you investigate any further
USB flash drives can fail for no apparent reason. Sandisk Cruzers are especially bad for this.
USB hard drives should be treated with extreme care. This is a real hard drive ! and knocks and bumps can quite literally kill them.
It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
Note that if you hear a drive clicking or pinging this could be the worst thing you would hear. Known as "The Click Of Death"
If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

yes you could simply format the harddrive in Fat32 using your macos that would be the best solution but don`t forget to backup your data by copy pasting the files on your mac or something else and after that to move them on the external hdd again to be available on the windows machine
Have you tried taking the files off of the drive and repartitioning and reformatting the drive? How is the drive formatted? Fat? Fat32 or HPFS? What version of Mac OS are you running? It is possible, depending on the version of the OS and the driver for the OS that it can have problems with drives that have partitions larger than 128 GB. It is also a bios limitation with older systems. Look to see if there is an updated driver for the OS X version you are running. Also check in the Disk Utility to see how the drive is partitioned and formatted. If it is going to be a Mac only drive, partition and format it as HPFS. If it is a drive that you will use in Windows as well, use Fat 32 and limit the partitions to 128 GB or less.
You could also try a newer version of OS X like Tiger or Leopard. They are both more stable than older versions and have better support for devices.
Format your hardrive for Mac OS: Go to Disk Utilities under the go menu in your finder. Select the external drive and click on the erase tab. Clikc erase again and it formats the drive. You can now copy files onto the drive.
The default format for the IOMega drive is FAT32. This format will work on all versions of Windows, as well as Mac OS9 and above. Unfortunately, FAT32 can't handle files larger than 4gigs. If you want to use larger files, you're going to have to remove all the files from your IOMega drive and use your computer to format it to NTFS (Windows 2000/XP/Vista) or HFS+ (Mac OS9/X).
I have several drives backed up and they work fine whenever they are imaged. anyway..
These drives are made for use in Windows and Mac enviorments. It is usually MAC users that have this problem.They are usually preformatted using fat32. because the drive is usually for storage fat32 is sufficent...but there are certain characters that fat32 dosen't care for...Do you have file naming scheme that uses odd characters? if so Those are the file names the error is refferring to. You may choose to reformat the drive using fat32(again) or NTFS(note fat32 has a better chance of data recovery just in case)your main hard drive might be NTFS.
The rest is only important if you use a MAC
Now if you have a MAC see below.
How do I initialise the external drive for Mac OS X?
Preparing the Seagate/Maxtor external hard drive in Mac OS X
Mac OS X cannot mount a FAT32 partition larger than 137 GB (128 GB binary value). Our partiton is 160 GB (149 GB binary value). Since your external drive comes with a large FAT32 partition preinstalled you will need to initialise the drive to use it in Mac OS X.
WARNING: Initialising or partitioning the drive will erase all data on the drive. If you have used this drive on another computer take the drive back to that computer and copy all data off of the drive before proceeding.
When the drive was plugged into the Macintosh you probably noticed a message reporting an error that it cannot read the volume. At this point you have the option to initialise the drive. If you missed that message you can initialise the drive manually.
Initialising the drive in OS X
If you see the volume error, you can click the Initialise option. If you do not see it, then go to Finder > Applications > Utilities > Disk Utility.
In Disk Utility: Select the external drive (149.05 GB). Be sure you select the correct drive before proceeding. If you have more than one 160 GB drive then be sure to select the correct one.
1. Go to the Erase tab.
2. Choose the type of partition (Mac OS Extended).
3. Type a volume label.
4. Tick the box that says "Install Mac OS 9 drivers". If this option is not selected, this device cannot be used by a computer running Mac OS 9. This option does not affect Classic.
5. Click Erase.
6. Read the prompt and Click on Erase again if you agree to erase all the data and you are sure the correct drive is selected.
7. The drive will now show on the desktop with a Firewire icon and the volume label as the name.
