Partition falied Input/Output Error

I have 2 iomega 160 gig minimax drives on seperate USB connections.

I just upgraded to 10,5,7 from Tiger

One drives works fine the other gives me an input/output error

Having changed the bad drive from USB to firewire 400 works fine and recognises the drive as an iomega.

Seems to be a problem in the OS,

Oh, the tail continues. The other drive also failed after a time.

Then on Firewire 400 it works like a dream.

Apple need to solve this bug.

It works on a Mac with Tiger but not on one with 10.5.7.
I bought the extern HD today and it does'nt work with this version of Mac. Also not with the driver.

I had the same problem last night. I took my drive over to a friends house to transfer some media files, he uses windows, but used MacDrive to access the drive. I got it back home and it would not mount. It spins up a bit, then a bit of clicking, then it appears in Disk Utility. But is incorrectly identified as a 2 TB drive, when is actually a 1 TB drive. I opened the case and found it is a WD10EACS Western Digital Caviar Green ATA hard drive. I tried first to use Disk Warrior but does not appear. Since my friend has most of the files, I could reformat the drive but Disk Utility fails to do that as well.

Is there any hope? I order Snow Leopard today, does anyone think that will have a solution?

Upgraded to Snow Leopard. Disk utility error, POSIX reports: Could not allocate enough memory.

I have given up on the data. I guess it is time to give up on the drive too. I just wish I knew what happen to avoid this in the future.

Yay, that worked for me too. Switched from USB to firewire and diskutility could format.

I was getting this error:
Partitioning encountered error on disk disk1: Input/output error (5)

Thanks!

I think I found a solution, check out full instructions:

Folks, after scouring the webs, I see that this is really a common problem for anyone trying to manipulate storage devices with Disk Utility. Several people have had look using older mac hardware and older operating systems. I find that to be sort of sad that this is the only solution for those people. However, none of that worked for me. I was trying to partition one of my old ipods (click wheel) for GUID so that i could use it for backup/maintenance/troubleshooting for my intel macbook pro. Disk utility just would NOT let me erase it or repartition it - giving me input/output errors.

Finally, what worked for me was to make a GParted Live CD (search for it, it's free open source), boot the computer with that, and use the GParted Utility to do it. It was a breeze!

Yup, which is the solution posted above.
