So I have this drive, and out of the box it formatted fine, but when I tried to isntall OS X, Twice in a row it came up with errors. I know its not the DVD becuase I already used it on a different drive today no problem. So I CHecked the drive media with norton and it came out fine. But when I try to check it with Disk First Aid, I keep getting this...
Verifying disk "Mac Hard Drive".
Can't open /dev/rdisk0s9: Permission denied
Verify completed.
And when I try to formatt it, Disk Utility either crashed or it will throw down a sheet saying its doing something that is a part of the format process, and it will hang there indefinatly. Its a Maxtor Hard Drive, and this isn't the first time I've had problems with Disk Utility :-(

this sounds like some weird case of corruption.. if you don't have a disk-fixer program like Diskwarrior, i'd recommend wiping it totally clean. you'll have to get the hard drive into a machine that's booted in OSX (or maybe an OS9 machine could do it with its Disk Utility). once you're up in OSX, try Disk Utility just to ensure the device number for the drive (in that last case it was disk0). after that, you can go into a terminal, su to root, and "dd if=/dev/zero of=/dev/diskx" where x matches the number from Disk Utility (this is important - you don't want to erase the wrong drive). this writes zeroes to the drive until it runs out of space to do it.
if you'd prefer to write random data to the drive (for security measures), use if=/dev/urandom instead.
after this, hopefully you can format. and things will be alright.

also, make sure that you're not installing an old version of OSX on a computer that's newer than that release (probably not the case since your OSX is on a dvd) - this can cause problems like booting because that version might not have had support for the machine you're using. just a head's up :c)
