OS X V10.7 Lion :: External Drive Reformatting / Lost Data?
Apr 1, 2012
I am running an early 08 MBP w/os10.7.3.I really screwed up this morning with a backup disk. my backup system consists of several external, stand alone drives and a HD dock and several internal HDs that plug into that dock.I had a stand alone Iomega/200G/USB that i wiped to give my son who doesn't "get" backups yet. I simultaneously had the USB dock plugged in w/ a Samsung 1.5TB HD powered on. I had moved the Iomega data to the Samsung prior to erasing the Iomega w/ Disk Utility. I had chosen the 7pass wipe on the iomega last night following the data transfer. it had completed 2 passes this morning w/ fourteen hours still showing til completion. i decided that three was plenty and disconnected the iomega to reconnect and select the 3 pass option to expedite. USB dock w/Samsung still powered on and plugged into MBP. disk utility defaulted to the samsung when iomega was ejected. I hit the three pass option and started the wipe without seeing Disk Utility default to the samsung. I did immediately see the flashing red data transfer light on the dock come on and realized my mistake. Immediately disconnected the USB HD dock. Disk Utility was showing "preparing disk" in its status bar. It appears that the formatting has been wiped as reconnecting the dock gives me a "the disk is not readable by this computer". I'm sure the data is still there, but the disk needs to be reformatted. The disk appears in the disk utility sidebar. all disk repair options are greyed out.
I am considering using partition in Disk Utility as that would reformat the samsung disk. However, the data on the disk would normally appear as a blue segment on the rectangular disk setup diagram. there is no blue. According to partition docs, you can partition a disk w/out the data being wiped. However, if the disk is unreadable when the partition process starts, will it wipe all the data as it partitions and reformats? Very reluctant to initiate this process w/out knowing more.

I have lost all my data from my harts drive. The laptop is under warranty. I have been told that they have replaced my hard drive but could not get any data off the old one. I have now lost all my data, photos, files, music etc. NO backups, only simply because i did not know how to do them. Is there any way of getting the files back? All my work spreadsheets and accounts were also lost.

I recently bought a 640 GB Comstar external hard drive for my macbook, and it came out of the box formatted in NTFS. I know that if the drive was in this format, I could not use it with my mac. So I opened up disk utility and tried to reformat it into Mac OS Extended (Journaled), but disk utility showed an error and the drive wasn't reformatted. So I tried FAT32 instead, and it worked. The drive has been working fine now, however, I have realized a limitation of FAT32: the files can only be smaller than 4 GB. This is a problem for me, so I need some advice. So here is my dilemma: I need to be able to share the contents of the drive over a local network that has both windows and mac computers. (Users on the network only need to be able to read the drive, not necessarily write). However, I can't use FAT32 because of the file size limitation. I'm not sure how to format the drive so that I (using my mac) can read and write it, and users on the local network can read it. I'm thinking HFS+ (mac os extended, journaled), but will windows users be able to read it then?

How long should it take to reformat an empty external hard drive? It's a GForce MegaDisk two terabyte hard drive and it's been going for about 11 hours with no sign of stoping.
Shouldn't it be pretty quick, since the hard drive is empty?

I just booted into Windows and saw that there were some Windows Updates available and it asked me to reboot the computer however it failed to boot into Windows. So I restarted and tried to boot into OS X instead, but that didn't work either.
So I put in the OS X install DVD and checked out Disk Utility. Turned out that all my partitions where screwed up. There were 3 partitions listed as Windows_ldm, with incorrect sizes (I had 4 partitions before).
Long story short: I'm now reinstalling OS X and I lost everything I had on the drive, I think. I'll try some restore software once I've gotten OS X installed.
A little pissed right now... How the heck can Windows F up the entire drive?

I have an external hard drive that is about one third full. Can I now partition it into 2 partitions in which the existing data is in Partition 1, and Partition 2 is empty and available for new, different data?

I had a WD external hard disk which I was using on my pc but not any more since I'm not a PC user any more. However, I'm a mac user now but when I connected my WD external hard disk I found out that I have lost everything on it. I thought may be because of my mac so I connected on my PC again and i have not seen any file which means I lost everything. Give me any software on mac that will get everything that I have lost.

Since I activated FileVault 2 on my Mac boot drive without initializing it, I'd assume that the same thing could be done for any other drive. I've got some external drives with hundreds of GB of data which I'd like to encrypt. Disk Utility lets do it by erasing the drive and encrypting the data written afterwards.
Is there any hidden feature that allows one to convert the drive without erasing it first, like the FileVault utility did for the boot drive (even when working on it!)?

I am embarrassed to say that last night, after taking care of my grandbaby for several hours and half-asleep myself, I intended to pull out my power cord to move my MacBook, but by accident pulled out the storage drive firewire. Of course, the drive appears to have been erased. It won't even show up on my desktop anymore.

l I now have to completely wipe, re-format and re-load OSX onto my iMac's internal HD, My iMac is a late 2009 27" and at present has OSX 10.8.5 loaded, ( loaded but with many miss-functions ). Prior to the problem the iMac was running OSX Lion, what version though I can't remember.I installed 10.8.5 the other day to see if that would fix things, but it hasn't. It was not a "clean install", just regular one from downloaded OSX 10.8.5.
I have run Disk Utility and TechTool Pro' 7 to try to make repairs to address the problems so far to no avail. Main problems are that my most used applications, FCP-7 Studio, Aperture and Photoshop CS5 amongst others, open but then immediately crash. I've reloaded the troubled applications, de-installed them properly with de-installation app's then clean re-installed them, but that's made no difference. They will not mount.
I reckon there must be a fault or corruption on the HD, probably caused during the Optimisation as everything was functioning well before I did that. So, the only OSX install disks I have are the original disks that came with the iMac, OSX 10.6.2 and a Snow Leopard Upgrade DVD OSX 10.6. I do have the downloaded copy of OSX Mountain Lion that I pulled from the App Store the other day and that copy is now on an external USB / Firewire 800 HD.
As I said I would like to be able to clean off the iMac's internal 2tb drive completely and install a fresh newer OSX. If I first have to load OSX.6.2 then upgrade via the App Store that's fine, but I'd rather just go straight to Mountain Lion if possible. Whatever works best. Getting rid of any corruption on the iMac's HD is the prime motivation.
All my applications and files are backed up to a 2tb LaCie external drive.The iMac has approximately 900 gb's of content onboard and the rest is free / unused space.

So, I've been searching the forums, as I just had a 1TB (well actually a dual 500GB) external drive stop mounting and start clicking on me. I'm trying to find a way to recover files, and I know I've seen a lot of posts on DriveSavers, which. I was searching around, and I was wondering if anyone has ever heard of a company called "OneWorld Data Recovery." It was something I stumbled across, but I can't find any reviews, or nail down anybody who's used it.
Clearly, this seems fairly suspect, but I figured I'd check and see if anybody had ever heard of it or used it. Thanks!

Basically I have a 750GB hard drive in my Macbook Pro and over 300GB is taken up with 'BackUp' data. This is more than the total of everything I have on the drive other than that. Time Machine has always been setup on an external drive and when searching all files on the Macbook there is nothing for backup files so don't know where it is coming from.

MacBook Pro, OS X Mavericks (10.9.4)

So, I'm trying to recover some lost files. I put it on Data recovery 3. Everything went fine until the power in my house went out, stopping the entire process. NOW when I try to run the process, it just stalls at 33,3%, with no indication of how much time left...

Need some help here. My friend is a DJ and had an external drive with tens of thousands of songs on it. The plug broke on it and I think that corrupted it since Eject was not used. I pulled the 3.5in HDD out of the case and hooked up up with some other external plugs I have.
When I run Data Rescue 3 on it, it shows that it sees almost all of these and the only two formats it counts up are mpeg and mp3s. Data Rescue then finishes the scan and has a bunch of crap files that are not needed, but none of the songs show up. What is going on here? Did I miss something in Data Rescue 3.
The drive is a 1TB drive and the backup drive we are using is 640GB, but there was only about 250GB of music on the drive to begin with.

Probably a stupid question but I can't figure this out as it is not covered in the User's Guide or in the FAQs on the Fantom website. I have an PowerMac G4 with an old Fantom 120GB external drive which is nearly full. I have purchased a Fantom Drive High Speed USB 2.0 (750GB.) How do I transfer data from my old Fantom to the new one?

Macbook pro 13' running 10.5.8 has intermittent issues with usb 2.0 mass storage drives but not jump drives. Here is the issue, my gf just got a brand new mac book pro 13'. This is great for her no more asking to use my unibody macbook. She plugs in the drive I have used for a very long time with my mac my pac etc. with not a hint of issue. The drive shows up copy's stuff off ok. However when it came time to return the data back to the drive it gets about 10% through and just hangs. Here is what I have done. I first thought ok might need a reboot. Then I went with the ok I will check her disk for issues. This is a 3 day old mac book by the way. I found random permissions errors with quick time which has never been run. After the fix the issue goes away for that boot.
The issues seems to come back after a re-boot or so. I go ok enough of this I format the mac with the system disk, then I update to the latest updates from apple. Plug in the drive and still having issues. Run the permissions repair same issues exactly format to format. I have also run the deep test off the system disk the machine checks out through that so I have ruled out ram on her system as a possible culprit. I am at a loss on this machine. I have gone so far as to format the external drive replace the data from my network server and try that. Still no luck. On my box there is no issue it time machines great it copy's data like a usb 2.0 drive should.

I have a Western Digital MyBook Studio eddition 750Gb plugged, via USB, into a MacMini (10.5.6). I store my whole music collection (~100Gb) on this drive, and a little while back, started to have trouble playing certain songs from within iTunes. iTunes would not error, it would just refuse to play the track. It then refused to play a long mix, which I had listened to from the very same source the previous day. I copied the same mix back from my laptop and diff'd the two. They where indeed different. If I run "file" on them both, sure enough, the working one reports "MP3 blah blah ...", the broken one "data". I have ran a find over the entire livrary and discovered that about 20% of the tracks are now reported to be "data". Whats more, the corrupted tracks seem to be in groups (entire albums or several albums by same artist etc.).
I'm assuming this is a hard drive fault, but I have run every check in both "Disk Utility" and "Diskwarrior", and no problems are reported.
Can anyone shed any light on what might be going on here, or offer me any advice on how to debug further?

I have a seagate external drive that I used to back up my windows 7 computer. My windows hard disk totally died so now I want to transfer all the files I need on to my mac. I bought the mac because I knew the windows unit was on it's way out. I am just not sure what to do now that it is reality. I have a hard time with this mac since all I have ever used was the windows stuff. I tried to find something in the FAQ but nothing is as close to what I want.

I was just upgraded from a 13" mbp on 10.6 to a 15" mbp on 10.7.3 and I'mn having a lot of issues with the UI changes. The biggest bother at the moment deals with window positions when I undock my laptop to take it to a meeting. I unplug all the cables, head to a meeting, and when I get back and plug everything in, my external monitor shows a blank desktop. I need to drag everything back into place for a two display setup.
If I move the menu bar to the external display everything will shoot over to the external display when docked, leaving the mbp screen empty. This is a real pain and I can't figure out what purpose it serves.
Is there a setting I could change to correct this behavior?

I originally formated my Drobo to 2TBs which I've now outgrown and need to reformat to avoid having two partitions. That requires that I xfer the data on a Drobo to another HD. Right now I have 1.2TB of data on the Drobo. I'm pretty a 1.5TB drive will be able to handle this, but not 100%. Will it once it's formatted? Next question: is migrating data from a Drobo to an ext. drive as easy as using Carbon Copy Cloner or Super Duper and cloning the Drobo and then using CCC/SD again to send the data back to the Drobo? Do these apps see the Drobo as one drive and Drobo does the rest, as it normally does?

I am trying to use my hard drive I have had for a couple years to back up some files on my computer, but the data I had stored on there already has disappeared. I previously had the hard drive connected to the Time Machine application, but have not used it in over a year when I received an error message trying to backup my computer using that application.
I know the data I already had on there is still on the hard drive because nearly half of the space on the drive is used up, but when I plug the hard drive in to my computer and open it there are no files to be found. I want to back up the current files on my computer, but I don't want to risk losing what I already had on the hard drive, so is there any way I can find and access the old files again?
I'll include my hardware information on here in case that helps to find a solution:
2006 MacBook Pro 15"
Intel Core Duo
Mac OS X 10.5.8
1TB Western Digital My Book: Studio Edition II
Dual-drive Storage System with RAID

Our old Toshiba External Hard drive has failed ( approximately 3 years old ). It powers on and the blue light comes on, but the fans don't spin and you can't see it in the finder or on my computer ( we tried on both PC and Mac ).
Any ideas as to how I can retrieve the data... without going to a specialist and pay ���, or would that be the only option

So my new Mini 2.23 arrived today and I'm trying to think of how I'm going to go about restoring the data from the old Mini. I've sold my old Mini, but used SuperDuper to backup to external drive. I have a MBP I can use if necessary.

I had to get a new hard drive put into my macbook pro because it was failing. So, I moved all my data onto an external hard drive so I would not lose anything. But now I cannot get iphoto or imovie back onto my computer. It says I cannot open it because it is a time machine back up. I don't want to have to purchase iPhoto and iMovie again just because I had to replace my hard drive.
