hard drive question!!! yikes!

[Chris Tompkins]

R U using the MAC Disk utility? Format the drive Mac OS Extended NOT Journaled it should work fine. Do they come up on the desk top of the G5 now?

ive been trying, i try to format it osx extended not journaled, buyt it reverts it back to journaled….

could it be a jumper setting?

Get Cocktail, a freeware utility, and turn journaling off after formating.

[Ed Dooley]

You can disable Journaling right in the included Disk Utility. Select the disk and go to File/Disable Journaling

He evidently can’t do that Ed.

[Ed Dooley]

I didn’t get that from his post. It sounds like he’s formatting it Extended, but it’s
showing up Journaled. I don’t read where he tried manually disabling it in Disk Utility,
but hey, what do I know? 🙂

yeah…its odd.

i am trying to format it, os extended, non journaled. and i do that, and it formats it, but it keeps reverting back to journaled. i triued to turn it off with cocktail, but i can’t copy more than 890 megs onto a the disc (for editing this is bad, of course)

anymore ideas, other than send these drives back?

Ben,

[ben] “they are usb2.0 enclosures.”

No one has mentioned this fact….

I would send the drive enclosures back. USB is not a good choice for working with video media files. Get an enclosure with FW400/FW800 ports. USB uses a burst protocol that is not as efficient as FireWire for transferring large files.

I am not sure why you are having trouble copying such a large file. A USB issue with the enclosure? There may also be an issue related to copying large files over USB from within the Finder.

A couple more suggestions (once you get FW enclosures):

• You may want to use Disk Utility and erase your drives with the “write zeros” security option (it will take a few hours to complete). This forces the mapping of bad blocks on the drive and helps to ensure that you are starting off with a pristine drive with no known issues.
• Using the Finder to copy and move large files is somewhat haphazard, in that the Finder doesn’t verify copies. Better to use a back-up/synchronization utility (with a copy verification ability).
• Also, with OS X 10.4, and later, the issue of journaling causing trouble is an “urban myth.” Too often, advice is given to disable journaling on media drives, but, in fact, it is only needed as a last resort when trying to eek out the last bit of performance from a disk subsystem and has nothing to do with reliable operation of FCP using journaled disks. Check out Sean Cullen’s FCP book for more info.
