mwr_allen Posted October 27, 2009 Share Posted October 27, 2009 Hi All, I have a major partition problem on my OS X 10.5.6 iPC installation. I have been running Mac on my Advent laptop for about a month now with hardly any issues whatsoever but today I bought a new 1TB hard drive which I want to use for the newer Snow Leopard operating system and I started partitioning the drive today while using Vista Disk Management into 5 separate partitions and all went well earlier today, just about an hour ago I booted into Mac and selected the Mac partition that I made and selected to erase with the settings as mac os (journaled) and afterwards I was missing 2 of my 5 partitions on that drive which I stored lots of data onto from another drive. Is there any way that I can repair this partition so that it shows up as a drive on either Vista or Mac which it doesn't at the moment. Thanks in advance. Marcus.

srs5694 Posted October 27, 2009 Share Posted October 27, 2009 It's impossible to tell from your description what has happened, and therefore whether any sort of recovery is possible. A pair of key questions will bring you closer to an answer: Did you use the Master Boot Record (MBR) or the GUID Partition Table (GPT) partitioning scheme for this disk? What were the partition start and end points, both before and after the problem occurred? The answer to #2 is particularly important; if the partitions' start and end points have changed, then it's likely that recovery will be difficult (meaning probably beyond your capability to do yourself, and very expensive if you have it done for you). If you don't know how to find the answers to these questions, then I recommend you start by reading up on the diskutil command in OS X. (I'm referring to the text-mode command, not the GUI Disk Utility program.) This program will at least tell you how the disk is currently configured, if not how it was configured before the problem occurred.

mwr_allen Posted October 28, 2009 Author Share Posted October 28, 2009 Hi, Thanks for your reply, I tried booting into Vista to use a program called Power Data Recovery and began a deep scan of the particular drive which actually showed up using this program but not in Windows Disk Management but then I fell asleep after starting the scan and just woke up to see that all the files have been found, PHEW!!!!. I think I will save all my data to a separate drive before partitioning my new drive again because if I actually lose this data then I think my wife will kill me because it's full of photo's that are not saved anywhere else. On another point, when I started partitioning the new drive yesterday in Vista Disk Management I noticed that I could make 2 new partitions on the drive but when I added a 4th partition it was highlighted in blue but brighter than the others which were highlighted in dark blue and when I selected to delete the partition it was fully highlighted in bright green with the text FREE SPACE on it, Not sure why this is but I will try partitioning the drive in Mac OS to see if that works better. Oh, and I didn't get a chance yet to check on your questions so I will check these out in a little while after the Data Recovery program has backed up my files. Thanks. Marcus.
