Ubuntu / Apple :: Recovering Accidentally Formatted Hard Drive?
Jan 16, 2010
I'm on the latest Ubuntu OS on my netbook trying to make a USB Startup Disk. I have a 1GB USB and a 500GB hard drive plugged in to then netbook. I run the USB Startup Disk program, and it tells me I need to format the USB drive. Okay, so I press format, only to realize that I'm formatting the 500GB hard drive.However, when I pressed format it give me an error saying the disk could not be mounted. I did something on Disk Utility and now I have a FAT32 system on the hard drive with nothing in it. Now my ultimate question is, am I able to recover the data that was on the hard drive?The hard drive was formatted in HFS+, it was a Mac-formatted hard drive. Will I need to use a Mac in order to try to restore my files?

I did something to my Windows partition that seams to be unrecoverable,so I thought that I would get my hard drive re-formated. But, I want to store my OS image (I'm sure that thats the right term... I'm just gonna hop you lknow what I'm talking about) on a CD. I know programs that do this for windows but I don't know any that can do this for Linux/Ubuntu.

Is there any way to make windows recognise my second hard drive (Which is fully exclusive to ubuntu) and access it? Iv'e been getting a few BSOD's since installing ubuntu and I'm pretty sure it's because windows keeps trying to access it and failing.

Ive got a Sony GRt816S laptop which Im trying to install 10.10 on to a freshly formatted hard drive. I downloaded the file burnt it to disk and tried to run it. I get to the first screen where It asks me if i want to run for CD, install or do memory check. - memory checks works fine but the install and run from CD options just hang before I get anywhere near an actual install screen (or anything that remotely looks like one)
I just see a purple ubuntu screen with 4 dots which alternate between red and white ocassionally. I've left it running over night and nothing happens.I read on the forum that it might be the original file, so tested it on a different pc and it worked fine. I know what Im doing with PCs but am a total novice when it comes to Linux, ubuntu or anything thing non-windows related .

I have recently gotten hold of a device that helps me plug my old ATA/IDE hard drive to my computer and view my old files that I wish to recover. I am using Ubuntu and the harddrive that I wish to retrieve the data from also has an Ubuntu install on it. The files I wish to recover are old .doc files, which I want to keep to remember my old writings.
The problem I have encountered arises when I wish to open some of the files. The icon for some of the files, which happen to be my best writings, has an X on the top right, indicating that I cannot view the contents. When I click on the files, the following error message pops up: "Access to /media/c885571b-a6e5-4a2d-937a-78af7050910/george/Courses/hist388/Passion.doc was denied."
Now, I am guessing that I need to be able to log in as superuser or something to be able to access these files, so I logged in my terminal as super user by following the instructions outlined on this page: [url]
I still did not have the sufficient access required to be able to open the files that I would like to retrieve.

I am trying to transfer files from a SATA hard drive with Windows Vista (Home Premium) installed on it. Some files I can easily copy over, others just say Access Denied.
I'm sure permissions is part of the issue, unofrtunately Windows is unable to boot at all (surpise surprise) so I can't adjust anything from within in. I know with XP drives I can easily copy and paste onto my Ubuntu machine. I'm using a SATA to USB converter that let's me plug it in and my desktop reads it like an external hard drive.
I've gone into the properties and under permissions it shows my account as having access to Create and delete files under folder access amd "---" under File access. My group and others show None and --- for Folder and File access. I can post a link to a screenshot tomorrow. I've tried to also select Read and Write for File access but it goes back to the dashes before I can apply it.
I am running 64 bit Ubuntu 9.10 and do not have the sharing aspect installed. Any questions please feel free to ask me.

I added a formatted LVM hard drive ( hdb: WDC WD800BB-55JKC0, ATA DISK drive) to my current server. I need to review its contents, save any data I need, and then reformat the drive and extend the current systems LVM to include the new drive. I am unable to mount the new drive using the following steps and need to mount the LVM new drive. As I explain below, I have learned that I am not supposed to directly mount an LVM volume. Here is the work I have done to date,.
1. MAKE SURE THE DRIVE IS FOUND:
dmesg | grep drive
hda: MAXTOR STM3160215A, ATA DISK drive
hdb: WDC WD800BB-55JKC0, ATA DISK drive
[Code].....

OK, was trying to make a live-usb boot partition on my 1.5TB HD; in doing so clicked a 'wipe disk' button.
A second later I realised what I'd done, clicked cancel (frantically), tried to unmount the drive but was told 'volume busy'. In a panic, unplugged the drive. Unsurprisingly, the drive is now a mess.
I'd had 1 30G FAT32 partition (empty) at sdd1, 1 1.5TB ext4 partition with about 500G of data at sdd2. Now according to gparted I have an unrecognised filesystem type; according to the 'Disk Utility' I have an unmountable 1.5TB FAT32 drive.
I know NOTHING about data recovery. If it's just a case of running a couple of magic 'check & fix' programs then I should be OK, but anything else and I'll have to take it to more skilled friends.

start getting Linux up and running. Like a lot of people, I chose an older computer I could fuss with, a 500mhz 256meg ram machine, and decided to install Puppy on a spare 40meg hard drive I have, as my bios does not boot from usb...I think...
Anyway, I have found that my bios does not recognize the hard drive when formatted to ext2! I have taken the drive and formatted it back to ntfs, and my bios recognizes it, and then back again to ext2, and nope, it's not there, thus I am still booting puppy from the cd...sigh...
Is my bios so out of date that I'm just out of luck? Is there anyway to check this?

I have an external USB hard drive that I need to recover some data from, but I see from fdisk -l that the partition uses LVM:
Code:
[root@localhost ~]# fdisk -l /dev/sdd
Disk /dev/sdd: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
I've followed various lvm tutorials all of which describe setting up lvm from fresh on empty disks. Unfortunately non mention how to 'install' new a drive that was previously set up with lvm. I have had a go anyway and may have now lost my data. Here's what I've ended up with (the partition in question is sdd1):
Code:
[root@localhost ~]# pvdisplay
--- Physical volume ---
PV Name /dev/sdd1
VG Name vg02
[code]....
I've tried mounting with other fstypes, but all give the same error.

I'm trying to fix my girlfriend's computer which is running OS X, which will boot but doesn't work beyond the login screen. I've removed the hard drive and can access most of the files, but she encrypted her home directory with "Filevault" and I think her home directory automatically mounts from some image somewhere. She does remember her password, but I'm not really sure where the encrypted files are on the hard drive and I'm not sure how to unencrypt them.I was thinking of trying to boot the external hard drive in some kind of virtual machine, but I don't know how to do that either.

While trying to create a bootable SD to install Ubuntu on a netbook, I accidentally formatted a part of a removable HDD that was connected to my computer. If I remember correctly, the partition I formatted wasn't the main partition of the HDD. In that case, does it make sense that the whole disk was wiped out? On that HDD there's a year worth of work, I really need that back.
I was using PhotoRec with some luck: it started to recover files, but with no names, which is almost useless, considering a lot of it are recordings - useless without their names. Is there any good recovery program that will recover all my files incl. names? Is there a easier oprtion, considering that I think I didn't really format the big partition of the HDD? What may it have been, the small partition?

I just installed kubuntu 10.10, replacing an older installation. I have three hard drives one of which had all of the data I wanted to save, about 500gb. I repartitioned and formatted the other two drives and made sure that the data drive would be mounted but not formatted. When I booted into my new installation, the data drive was blank. I'm not sure if it's relevant, but I had just upgraded the file system from ext2 to ext4 before starting the installation.
I've been trying to recover my lost partition with testdisk. The website has instructions for recovering a formatted partition. It looks like it's working until the instructions tell me to choose Boot and RebuildBS, which I don't see as options. Can anyone give me any advice on how to recover? How did this even happen? Has anyone had a similar issue with installation?

I was installing 10.10 x64 today. I wanted to manually partition the disks, since I have a /home partition from a 9.10 installation which I want to keep.Unfortunately, I selected to convert the ext3 /home partition to ext4 and didn't realise it was formatting the partition until it had just begun. In desperation, I pulled the power plug, but now I can't access the partition (using the LiveCD) - comes with an input/output error.What are some strategies to recover the data on the partly formatted partition? I don't think much, if any, was actually formatted.

I have a Ubuntu box with two drives, one of them is where Ubuntu is installed and the other one is where I store all my music, photos and other documents. I recently bought a Mac and I want to be able to access the drive where I have all my documents from my Mac. Is there a way to accomplish this? I've been looking all day for an answer to this but all I can find is how to share a folder instead of a whole drive.

I've recently bought the "new" Macbook from Apple. It obviously came with OSX preinstalled. And I'm obviously not satisfied with the way it works, I also need a FAT32 partition so I can share my files between all three OS's. Tricky business. And I thought later on I might try and create me a nice LFS system to learn about Linux and show of to my mates. But doesn't a single hard drive only support up to 4 partitions? So off I went and got Ubuntu running besides Mac. It wasnt recognized by neither the default boot-loader nor rEFIt straight away. I had to hold alt to come up with the special BIOS or something every time I needed to use Ubuntu (always).
I got up to a point where I could run Ubuntu with wireless, sound and pretty much everything working. Until the kernel updates were installed. Somehow I (or maybe it) managed to screw up and booting had become impossible, for it would crash halfway through with kernel errors and other undefined weirdnesses. Meanwhile I had tried installing Windows 7 on a different partition. Which I found to be catastrophic also. I was forced to put up with OSX, which in my opinion is fine at what it does but it doesn't do very much for me. After a couple of tries I had to give up on fiddling with Ubuntu for I needed Windows 7 to run software for school. So my current partition layout looks like this......

I just installed a new hard drive with OS X on my iMac G5 PowerPC. The drive size is 1TB. OS X Leopard is currently only using about 80 gigs of that space. For some reason, at the disk preparation from my live PowerPC Ubuntu install, the entire bar is green with only 8kb of (white) free space. I want to partition the computer to add Ubuntu to it, but I don't want to risk partitioning my hard drive and losing any data affiliated with the current o/s installed on it (OS X Leopard). What is the best way to go about doing this? A manual partition?

I was trying to reformat my Seagate external hard drive and I selected "free Space," in disk utility not realizing that the computer would no longer recognize the device. I'm trying to install Snow Leopard on it so now how do I format it now to the GUID format? I luckily backed up the entire contents of the hard drive (The essential files on it), but what do I do now that the computer doesen't recognize it!?

Recently my laptop broke down and wont start up. I'm currently trying to recover my files to my mac with an IDE to USB cable. It recognized my windows partition fine and I was able to get all my files off of that, but the majority of my stuff is on the ext4 partition that I have on it. Does anyone know how to access the ubuntu partition of this hard drive from my mac?

I like to check out movie trailers on trailers.apple.com I also like using Opera I know there is some issue with apple and the code for the new streaming codec version or something of the sort. Also, I can't even download the trailers from the site to watch them from my hard drive. It's like the linking system wont function properly.

I have a Macbook 2,1 since 2007. Last week my hard drive just died, so I decided to replace it with a new one, no problems with that. The problem came when I had to install an operative system, because my DVD drive has been broken for a year and a half now. I know we can easily install MacOSX from an external usb drive, but I don't have a big enough pendrive at the moment. So I went for Ubuntu. I have managed to get an Ubuntu 10.10 live usb stick working like charm, if anyone is interested. I just downloaded the latest i386 iso and followed this advice by pxwpxw for the 32bit EFI.
The only thing I had to change in the boot.cfg was the name of the iso and -very important- changed initrd.gz for initrd.lz. The live usb works great. But I decided to do an installation on the hard drive. I installed it using the whole hard drive and didn't get any errors. But when I boot the macbook it doesn't detect anything. I guess I need an EFI bootloader or something to make it work. I've tried to follow this guide but it seems to be intended for someone who already has MacOSX and the Ubuntu installation working. I just want to install a bootloader or whatever I need from the "outside" (from the live usb I'm using). I tried to just throw reFit into the main hard drive's root folder but it doesn't work. I think that maybe creating an HFS+ partition and installing reFit in it may work, but I don't think I can create that kind of partition from the Ubuntu usb and I also need a working MacOSX to run the enable.sh. I've also read of elilo but I've seen that it hasn't been updated for 3 years

My colleague needed a backup for some of his loose media, so I assured him I could back it up on our Lab's Lacie 2TB external. His windows partition was incredibly sluggish, so he booted into ubuntu 11.04 and we partitioned and formatted an NTFS volume for him to transfer his stuff to. The format went fine, space was available, and I left him to transfer all of his stuff from his dell studio1555. He finished and reformatted his computer completely.
The NTFS is not recognizable by any of the OS now. Ubuntu sees it as a single partition without any data, whereas before the transfer, the partition map was clearly visible. Windows does not recognize the drive at all. OS X does recognize the partition, but it shows up as an apple_scratch volume, which is quite a bit frightening, considering a scratch volume is essentially blank. To elaborate, all of the files were in his windows partition, and were transferred within a relatively fresh install of ubuntu (not much had been done on it). The partition was made in diskutility in ubuntu (the GUI), but the rest of the drive was HFS+ formatted.

One of our home school students, toying with the Power Management panel on our 700mHz iMac since there are no brightness control keys that work on it, set it for full display blackout and now can't get the screen back since we can't see the controls. We turned the machine off and on but his account keeps blacking out on log-in though it doesn't happen with other accounts. How can we fix this to retrieve all his work?

I am in the process of recovering data from some damaged hard drives.
I am copying the data to a recovery folder on the safe system disk where it is being sorted.
Some of the data/files I do not want to keep.
I want to delete them.
However the permissions are such that it will not let me.
I need to be root.
I don't really want to flaff about in the 1980's geek terminal environment ... just want to right click and select delete.
Is there any way within the GUI to be as one with Root, all powerful, all seeing ......
