OS X V10.7 Lion :: Enabling FileVault On An External Drive Without Erasing Its Data?
Jun 11, 2012
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 have an external hard drive that I was previously using on PC, having attempted to use it on a Mac, it will not write to it. I've found that I have to format to FAT32, which I think i can just about manage (yes, im a girl) but my concern is, if i format through the MAC, will i then lose what's on the hard disk as the tab says 'erase'? I have a lot of images on the hard disk so am a little petrified! Any advice for this really basic question would be appreciated!

I would like to use FileVault to encrypt both my hard drive and time machine back up external drive. Does encryption noticeable slow down the computer.

In the effort to use Time Machine, I want to partition my external drive. I have 500 gig external, and would like to have one partition of 480 and one around 20. This way, Time Machine will only back up onto the smaller partition, not endlessly backing up until all 500 gigs are used. The reason I need to partition without erasing is my 170 gig iTunes library. Its too large to transfer to my internal HD, and I have no other drive to store it on.

I have a WD external drive that was set up as my time machine backup disc with Leopard. I want to erase the disc, but when I try to erase it using disc utility, it tells me "Disk Erase failed with the error: Unable to write to the last block of the device".

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 had used FileVault 2 on the entire drive and had later deleted all contents. After changing my mind, I used SoftTote Data recovery for mac to retrieve the deleted files. So now I have a bunch of reconstructed .dbf files and such, but I don't know how to access them. Any better way to retrieve the data I regretted deleting?

After backing up my data and then swiping my hard drive using Disk Utility, my OS seems to have been uninstalled as well. Is there a way to recover the deleted information and go back to the last working configuration? I'm on a MBP IC2D 2.16 w/ Lion.

I recently did a fresh OS install of my mac. I knew that everything was safely backed up on my external drive (through time machine). However, for some reason my filevault home folder ISN'T showing up on the external drive. I am quite certain the files are there, it's just my mac can no longer read them it seems....Is there any way to recover this data?

I recently upgraded to Yosemite and now have to enter my password every time I boot up with I find annoying. It seems I need to disable FileVault to solve this problem but when I try I get a message ' FileVault is encrypting the data on your disk. Wait until your disk is fully encrypted before turning off fileVault'.

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)

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 have an External 1 TB HDD where 250 GB of it is dedicated to Time Machine back-ups. I only have about 25 GB of space left but Time Machine won't update .. says there's not enough space. I thought that TM auto-deletes the oldest entry? Well it's not working. What should I do? Do I need to do into Disk Utility and just highlight my TM Partition and erase it then start over? There's nothing on it that I need.

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.
