Title: 80 gb hard drives appears as 31.5
Post by: joe9173 on December 26, 2003, 06:59:43 PM
Recently i have been reformatting / repartitioning/ installing system software on my 80 gb maxtor 7200 rpm hard drive which in the past has worked fine.  Just a couple of minutes ago I noticed that it is showing up as a 31.5 gb hard drive.  Where did the other 50 gb go?  Is it time for a new hard drive?

Thanks.

That may just be for one partition.

In Disk Utility is says the drive itself is 31.5gb as well as the only partition inside it.  It's connected via firewire, if that makes a difference to anything.

I don't have anything important (or anything at all for that matter) on the hard drive right now, so I'll do whatver is necessary to fix it.  But I've already tried reformatting...

It's on my iBook g4.  It'a a maxtor 80gb 7200 rpm hard drive inside a "pryo 1394 drive kit" (external firewire encasing).  The drive used to be in a 350mhz g4 tower until i put it in the firewire encasing this week.  It worked fine inside the encasing until i reformatted it a few times.

 This is a very common issue with hard drives.

Most hard drives have a jumper which, when set, changes the drive into a 32GB drive. This is because many PCs shipped with a BIOS limitation that prevents them from working with any drive bigger than 32 GB.

Examine the drive closely; I'll bet you'll find a jumper that is a "size limit" jumper. Change its settings.

At first I read your post and thought that can't be.  When I took the drive out of the g4 tower it's only jumper was set to "slave".  In order to put it in the firewire encasing it had to be set to "master".  So naturally, I switched it to master, put it in the firewire encasing, connected it to my iBook, and it worked perfectly - 80gb.  I'm guessing it was the first time I reformatted it that it appeared as 31.5 gb.  I just changed the jumper to "cable select" and reconnected it.  It appeared as 31.5 gb again.  I reformatted, and it's 80gb.  So apparently it was the jumper - but it didn't take effect until after a reformat.  So now I'm all set.  Very interesting.  Thanks for your help.

I had this very same problem with my 120GB  HD appearing as a 32GB one that I had put in a firewire enclosure. Then one day it worked...I can't recall if I had changed the jumpers or not. But if it happens again, I'll try this!
