Seagate FreeAgent Drive Problems

[yvettegr]

I have an iMac 2.4 GHZ Intel Core 2 Duo running Mac OS X 10.5.5.

The 500 GB Seagate Harddrive shows up with the info that 391.37GB is used with 74.27 available. But when I click on the hard drive it show the 74.27 available but shows zero files.

Sometimes, when I click the hierarchical structure shows up and as I click on a folder it disappears until all the folders have disappeared.

When I try to run Disk Utility I get two errors:

Unable to checksum EX-8 (name of the drive). (Permission denied)

First Aid failed
Disk Utility stopped verifying "EX-8" because the following error was encountered:
Filesystem verify or repair failed.

I tried running Repair in Drive Genius 2 and get the following error:

Device Error
Unmount failed for device 'disk2s3' with 'Operation not permitted (The disk may be in use by an application.)' (0xC001).

Any ideas anyone?

is it an external hard drive? or is it a hard drive inside an external drive enclosure? ...
have you tried using the disk utility to re-partition it? ... i would use the "erase" tab in the disk utility and recreate the partitions in the "partitions" tab.

i actually am not a fan of seagate. in my experience they kinda suck for hard drives. i wouldn't be surprised if it was something wrong with the actual hard disk.

i would also try using a different port (is it usb? or is it firewire?) and restarting your computer with it plugged in to the new port. and maybe even try it in a different computer to see if maybe windows will reformat it for you and then you can take it back to your mac and reformat it for mac.

Was the drive always used on a Mac? Was it pre-partitioned and where did the data that is on it come from?
