1TB Iomega External HD not working normally.

Iomega Prestige external 1tb hard drive
December 29, 2010 at 14:39:45
Specs: Mac OS X 10.5.8, 2.4GHz Intel Core 2 Duo/ 2GB 1067 MHz DDR3
I have a 1TB Iomega external hard drive (Model: LDHD-UP). I have my Time Machine back ups as well as my entire iTunes library on it. It was working fine but now when I plug it in, it does not appear on my desktop. I can see the hard drive under disk utility, it is listed as "931.5 GB Iomega External HD Media"...It used to show up on my desktop as "MBs 1TB".

The hard drive sits on a desk, has not been moved, and never been dropped or anything. I just turn it off when I shutdown my laptop. Please someone tell me there is a simple solution and I have not lost all of my media.

try test disk

Only try this if you cannot see your files otherwise see the next response by OtheHill as that is the correct explanation. I wrongly assumed you could not see your files.

The size you posted 931.5GB is the correct formatted size for a 1TB hard drive. There is nothing wrong with your drive. The difference comes from two different methods of measuring the capacity. The actual capacity is multiples of 8, which is one bit. 1KB = 1024 bits. 1MB = 1024KB, 1GB = 1024MB, 1TB = 1024GB.

Drive manufacturers round off using 1000 as the number, instead of 1024. Multiply the advertised capacity by .931 and you will be close to actual. 1000GB x .931 = 931GB.

Be sure to always use the safely remove icon by the clock before disconnecting your external drive.

How does disk utility show the disk space as?
How was it formatted originally?
Have you tried the repair options within the disk utility?
If yes what error reports if any do you get?

Under disk utility, it does not allow me to "repair" the disk but it will let me "verify" the disk. After the verification is done I get a message that the hard drive needs to be repaired. The error it is reporting is "Incorrect number of thread records." So is my only option to back up the files and then erase and reformat the drive? If that is the case, I'll have to go buy an entire new hard drive anyways just to have something big enough to hold all the files that are on my 1TB.

As far as disk space goes, it just lists a total capacity of 931.5 GB. Originally it was formatted as Mac OS Extended Journal. My post above shows the extent of my repair attempt and the error associated with verifying the disk.

I am moving this thread to the mac forum. I don't know much about macs either. I think you will get better results there.

It could be the Enclosure Electronics are faulty, it should be a standard hard drive inside, if that is the case buy a new drive enclosure......
