nickytl Posted December 21, 2006 Share Posted December 21, 2006 Hi, Bit of a problem here. I had 10.4.5 running fine. My hard drive was partitioned windows ntfs (visible and mounted) os x HFS+ (os x installed here ) data HFS+ linux ext 3 (visible in disk utility) linux swap (visible in disk utility) after updating by putting in the jas 10.4.8 sse3 intel only dvd and click click click Ive lost the data partition. It shows as free space in disk utility. Ironically i moved a load of stuff there from the os x partition before the upgrade thinking it would be safer. If anyone had any ideas Id be grateful to hear them as to how i might get it back. Im downloading a linux boot disk now to see what it can see on there. Im guessing the install did something to my MBR Thanks nicky Link to comment https://www.insanelymac.com/forum/topic/36493-missing-partition-after-upgrade-to-1048/ Share on other sites More sharing options...
thestevo Posted December 21, 2006 Share Posted December 21, 2006 Ok, I believe it would help if you give us a little more information. Namely, what exactly did "click click click" consist of and how big is this new free space that is shown? Is it exactly the size of your data partition and did you loose anything else?

nickytl Posted December 21, 2006 Author Share Posted December 21, 2006 the click click click was basically i selected just the 10.4.8 combo update, mifki kernel, gma950 support and install. It installed. I rebooted. Perfect except that Im missing that partition. Im not certain what the original size was but the free space is 139.72GB my win is 19.53 os x 50.34 linux swap 1.87 linux 21.42 thats a total of 93.16 disk utility sees it as a 232.9GB disk so thats all the space accounted for. Its the only disk in the machine. the data partition used to appear in the list at boot up but not anymore. Windows and linux still boot fine.

nickytl Posted December 21, 2006 Author Share Posted December 21, 2006 one other thing, in disk utility it lists the partitions in the left pane as Untitled OSX disk0s5 (swap) disk0s6 (linux) with the two disk0s greyed out Link to comment https://www.insanelymac.com/forum/topic/36493-missing-partition-after-upgrade-to-1048/#findComment-259613 Share on other sites More sharing options...
thestevo Posted December 21, 2006 Share Posted December 21, 2006 Do you happen to know whether this HFS+ data partition was extended or primary? You can only have four primary partitions or three primary and however many extended. I'm guessing you put your linux install on the extended, but just checkin'.

nickytl Posted December 22, 2006 Author Share Posted December 22, 2006 unsure as it was a while ago Im afraid. Im looking at the instructions i followed then. On the plus side Ive booted linux and typed fdisk -l and it shows /dev/sda1 1 2550 20482843 too much typing. Hang on and ill switch to linux Link to comment https://www.insanelymac.com/forum/topic/36493-missing-partition-after-upgrade-to-1048/#findComment-259637 Share on other sites More sharing options...

Wheres /dev/sda4? hmmm so yes the linux is sitting in the extended. The ntfs and osx show up as expected and my data partition has vanished Link to comment https://www.insanelymac.com/forum/topic/36493-missing-partition-after-upgrade-to-1048/#findComment-259639 Share on other sites More sharing options...
thestevo Posted December 22, 2006 Share Posted December 22, 2006 You may want to use a partition recovery software, there are many choice out there; both free and commercial. Hiren's boot CD might be of use to you. Look online for guides on how to use data recovery software included on that.

nickytl Posted December 22, 2006 Author Share Posted December 22, 2006 yep, thanks for your input. I actually tracked down a few posts from people with the same issue on the thread for installing this jas 10.4.8 version. Im running testdisk now under linux to try to rebuild my partition table. Really wish there was a better way to search this forum. I found the relevent posts searching for "testdisk" nothing undeer missing partitions. Ah well hopefully its a goer.

theyangster Posted December 22, 2006 Share Posted December 22, 2006 hmmmm, same thing happened to me, but it wasn't after installing the 4.8 update, I managed to recover 4 partitions, but the important one (with some data that I would like to have back) has vanished, I haven't touched that partition since b/c I might be able to fix it... So if got anything to work plz lmk too Link to comment https://www.insanelymac.com/forum/topic/36493-missing-partition-after-upgrade-to-1048/#findComment-259677 Share on other sites More sharing options...
nickytl Posted December 22, 2006 Author Share Posted December 22, 2006 ok fixed it now. Testdisk was no use. It was "discovering" partitions all over the place. Had I written what it thought was my partition table i would have wrecked my windows and linux. Simple solution was i ran fdisk /dev/sda (sda for sata disk 1). As indicated aboved dev/sda4 was missing. I selected n for new partition, selected to make it primary (as thats what the missing one was) and acccepted the defaults of where to begin and end it (which was the last 15000 cylinders). then i hit t and set its filesystem to af. Then i selected to write changes and exit. On rebooting os x picked up the partition fine. I had linux installed so I did all this from a root shell but any linux boot cd will have fdisk on it. I guess the thing in these situations is not to panic and start throwing fixmbr and scandisk at your disk. All that was corrrupted was the partition table not the partition it self.
