Lacie 500GB external hd won't work...

[mightyjlr]

I just bought an external 500gb Lacie hd, and it won't mount. It shows up in Disk Utility as LaCie Group SA, but shows it has 0 bytes. I also cant partition, and I get an error when I try to erase. Anyone have any ideas?

anyone?

Have you tried viewing it in Disk Utility? It's possible that it's not formatted.

FireWire? USB 2.0? eSATA?

What are the exact steps you're taking in trying to set the drive up -- from connecting it to formatting it to trying to mount it?

Check with fdisk. For example on my Lacie, I get
asperta# fdisk /dev/rdisk1
Disk: /dev/rdisk1 geometry: 72967/255/63 [1172229264 sectors]

OK, I don't remember if I partitioned the disk with OS X or Linux, since
I had some problems with getting three different filesystems (HFS+ for
OS X, NTFS for Windows and XFS for Linux), but if you get no partitiontable,
something is wrong, alright.

BTW. Use sudo su - to run fdisk.

It is a firewire 800 hd. In disk utility everything in First Aid is grayed out. Under erase I try to erase it and it says "The chosen file size is not valid for this filesystem". When I try to partition it says "device not configured".
