Mahinavai Level 1 Level 1
A power failure removed my Lacie 500GB hard drive from my MacBook Pro running Leopard. When I reconnected it the hard disk wouldn't mount. Using Disk Utility I was able to see the disk, it says its not a mac formatted disk, but a pc-formatted disk and won't mount it or repair it (I have never connected it to a pc and it very definitely was mac-formatted before--I hadn't partitioned it or anything but used it straight out of the box). I had a friend come over with his PC laptop and it mounted there with all the files seemingly intact--we opened some of them and everything you're not supposed to be able to do this without the appropriate application! I've no idea what happened. Any way I can get those files back for my mac to read without reformatting the disk and losing what still is there. PLEASE HELP. There's 300GB of files in there.

MacBook Pro 15", Mac OS X (10.5.1)

Mahinavai, Welcome to the discussion area!

I'm not sure why you posted in this discussion area? This area is for iBook G4s.

Since you have a MacBook Pro you should post your question in the MacBook Pro or Leopard OS 10.5 discussion area.

Hi,

Welcome to the Discussions.

If you used it right out of the box without formatting it then it's probably formatted FAT32 not HFS+. If you can get Disk Utility to repair it then you'll need to save the files on a PC and then format it HFS+. You could then network with the PC to retrieve the files. PCs can't read HFS+ volumes so you can't connect the drive to the PC. Your other option would be to format it FAT32 (MS-DOS) then you can connect it to the PC to get your files.

John

    Sorry, I saw a problem that was similar, I didn't even realize what forum I was in.

    Thanks, I had already gotten my hd repaired, but I partitioned it the first time and it went stopped working. Now I just make sure to eject it as soon as I'm done using it, and then power it down. Unless there is a way to partition the hd to be on all the time with out it being read if I decide to restart the computer of if there is an outage it boots back up automatically.

    Well, I smoked and drank and sang Hallelujah. As strange as it may sound I plugged it in to my mac this morning just to check things out and it mounted and everything was in there. Disk Utility said it was Fat formatted and I ran a repair--everything seemed back to normal except Disk Warrior still said it wasn't Mac-formatted and wouldn't mount (but there it was....). I connected it to my father's computer and copied everything just in case (can't trust it anymore). I've no idea what happened, can't explain it, but cheers, puff, Hallelujah.

    Glad it's working again.

    Disk Warrior can't repair FAT32 volumes (a PC file format), only HFS (Mac file format).
