Apple Mac Laptop - 250GB Hard Drive recognised as 1.8TB and won't format
Posted on 2011-03-24
I've got a Macbook laptop (Model A1181) in front of me, which doesn't boot. Booting from the original install cd shows that there is no hard drive being recognised by the system. I've purchased a new SATA hard drive, installed in and booted back into the install CD. The hard drive is now recognised correctly in the System profiler.
When I look in Disk Utility to format the disk, it's size shows as 1.8TB even though the drive is only a 250GB drive. It won't let me format it, even if I set the size to 0.1TB (i.e. 100GB) as a test.
I then tested further by plugging the hard drive into a Windows PC, and it works fine. I added a partition, and moved some data to the drive. I then removed that partition, tried it back in the Mac but same problem exists.
Does anybody have any advise about how to solve this issue?
