Installing a new 250gb Seagate Ultra ATA/100 into a OWC Mercury Elite 3.5" hard drive case. This case has been working as I just removed a 20gb Seagate unit from it.
I have tried setting the jumpers at Master and Cable Select as the OWC web site suggests. The drive is not recognized by Disk Utility. System Profiles says it is an unrecognized FireWire Device.
I put the 20gb back in and it is recognized. What is preventing my iMac G4/1.0ghz, 768 RAM operating with OS X.4.5 from recognizing this?
I have also tried several different FireWire cables, all to no avail.
Help and thank you!

How new is that Elite box?
I thought older ones couldn't use larger drives, but I don't remember what the limit is/was.
Can you put the 250G HD in another box or your Mac? (I don't know if your Mac has the 128G limit. I can never remember when it was lifted.)

Can you try the drive in another case or system?

Even if it were an older unit (it's not that old as it has USB 2 on it) it would only limit the size of the drive, not the entire drive itself.
Guess I will try another case but that makes no sense if the case is working for the 20 gb unit.
I'll be back . . .

What are the jumpers set at Master or Cable Select?
Does it match the 20 GB.
Be careful---if you format the drive in a Mac or an external enclosure that doesn't support larger drives--It is a PITA to regain the lost space.
The larger drive should show up and mount even if the case doesn't do large drive--just don't format it.

Right, but it will tell you if the drive is alive.

Might be a firmware update. I have two enclosures from Bytech via PCmicrostore,com that wouldn't work with a new 300GB drive but would work with a 160GB - called them up and they referred me to a site to update the Oxford chip firmware - worked like a charm.
OWC should be able to tell you what the problem is.
