When initializing the HD, I get a failure due to Input/Output error
I removed a 30 GB HD from a G4 iBook (1.2Mhz) and replaced it with a 40 GB that already had OS 10.5 on it. The laptop works and the old HD worked in the laptop prior to removal.
I placed 30 Gigger in a 2.5" enclosure and when I connected (either by way of the USB or the Firewire), none of my computers will 'see' it, not even the iBook I removed it from. I have a MacBook, the G4 iBook and a dual G4 Quicksilver.
I tried Drive Genius II and my old copy of SystemWorks 3.0 and they could not 'see' it either.
I tried Apple's Disk Utility and now I could 'see' it as a drive on the left but when I try to initialize it (quick initial only, don't want to destroy the data if I can help it), I get the error msg initialization failed Input/Output Error.
I know this sounds silly, but I've gotten various errors from disk utility that were overcome by simply trying multiple times, i.e. an error the first and second try, but on the third it's worked for some reason. Sometimes rebooting and then trying again has helped as well.
Another thought -- this is a longshot, but do you possibly have an external enclosure which requires a second USB connector in order to power the drive? Some external enclosures cannot power a drive via a single USB connection, and they therefore come with a second cable which can be connected to a second USB port in order to provide additional power. I've seen cases where if only one of the two cables was connected, the drive was somewhat visible, but erratic behavior ensued, and the drive was not fully readable. Again, a long shot, especially if you've tried another drive on the same computer with success, but I thought I'd mention it.
