Password protection for external hard drive

is anyone aware of a good, reliable program which allows you to protect data on your external hard drive with a password?

Actually, there's really no reason to make the disk image the size of the whole hard drive. It would make it convenient in a way, since the disk image would have plenty of room on it, but it would also make backups a major pain in the arse, since one minor change to one file inside the image file means the whole thing has to get backed up. If you've got a 150 GB drive, that means a change to a 4 k file requires that you back up 150 GB. (And where do you back up several incremental backups of a 150 GB file to, anyway?)
What I would recommend is to use many smaller disk images. For example, if you've got 10 projects on the drive, each taking up, say, 150 MB, then you could make 10 disk images that are 200 MB (or more or less, depending on anticipated growth of the projects), and put the files for each project inside one image. Change one project, you only have to back up one image file, which is only a fraction of the total size of the drive. Even if you made each image file 1 GB -- an order of magnitude larger than the project files -- it would still be something you could easily back up onto a DVD, and all 10 disk images would still only take up less than 7% of a 150 GB drive.

Help- how to password protect an external hard drive?

I'm just stuck. There must be a way to encrypt or password protect an external hard drive. No?

The easiest way is to make an encrypted disk image of the folder contents with Disk Utility. Go to Disk Utility's File menu -> New -> Disk Image from Folder. There you can pick an encrypted disk image. Once you have made that image, delete the folder that it came from and leave the image behind. Mind you, there is always the risk you might lock yourself out permanently from that data if the image becomes corrupted. You are safer keeping the external hard disk in a physically safe place when not in use.

How do I password protect the external hard drive used for Time Machine backup

Can anyone help me to put password protection on the external hard drive I use to Time Machine backup my iMac internal hard drive? I use Snow Leopard 10.6

I think that was FileVault 1. Starting with Lion (10.7) Mac OS X uses FileVault 2, which is whole disk encryption.
Based on complaints seen in these forums, I would say FileVault 2's only complaint has been when people forget their password/encryption key (it seems an encrypted disk does prevent anyone without the password from accessing the data, including the real owner). Otherwise it does not seem to be causing any serious issues. Your Mileage may vary and objects are closer than they appear in your side view mirror (standard disclaimer). Of course this is all academic while you are using Snow Leopard (10.6).
There are other whole disk encryption packages available, such as PGP Whole Disk Encryption, HOWEVER, I would not advise it for your Mac OS X boot disk, as it has been known to be a problem when you try to install operating system updates or upgrade to a new version. NOTE: I have not seen PGP Whole Disk Encryption discussed much, ever since FileVault 2 came along.

Password Protecting An External Hard Drive.

I am running 10.6.2 on my Macbook Pro 2.33 Ghz Intel Core 2 Duo.
I've just used Super Duper to back up and make a bootable copy of my Macbook Pro's internal hard drive. My question is can I password protect this new external hard drive, and it if it password protected, will I still be able to boot up from it should anything go wrong with the internal hard drive?
If the answer is yes to both questions, then I would very much appreciate some tips on how to go about this.
Many thanks in advance.

there are no built in tools for that. but you can turn on filevault on your home directory and encrypt your home folder. that's enough for most people as there really isn't any sensitive data outside your home directory. then of course the home directory on the clone will be just as protected.
if you want full disk encryption you need to use 3rd party tools like TrueCrypt or PGP encryption. I'm not familiar with them and don't know if they allow you to boot from encrypted drives.

How do I password protect an external hard drive?

I'm using a 500 GB external hard drive to back up my PowerMac. I'd like to find a simple, robust "password protection" tool or software, to password protect this drive, in case it falls in to nefarious hands. If it's free, that's fine, but I'm also happy to buy. Any idea's?
Thanks!

Hi-
The best protection for your data, is to maintain the data as a encrypted disk image. This will provide both the need for a password, as well as decryption. Creating a "sparse image" will require a password to open:

Ext. HDD passwords, in OS X, are just permissions, which can be changed, or hacked, and don't give much protection.

How to password protect an external hard drive

I just bought an external HD to use with Time Machine and for some extra space, but I would really like to password protect it. Since it has all my files on it, it is just as important as password protecting my computer. I'm thinking I probably have to use Disk Utilities, but I'm not quite sure how to do it.
Please be as detailed as possible, because I don't delve into Utilities very often.
Thanks
P.S. My HD is a Toshiba Portable Hard Drive, if it makes any difference. It advertises on the back that it can be password protected, but I have been unable of finding any way to do so.

Hello FidgetingFinhc,
The best protection for your data is to maintain the data as a encrypted disk image. Creating a "sparse image" will require a password to open:
I would follow the instructions provided by the Apple Support document below on how to make this happen.

AC cords for external hard drives?

okay! everyone uses external hard drives, yes?
It's great that they connect to computers via standardized ports & cables: USB, firewire, eSATA.
but why is it that the power cords for external hard drives are completely unstandardized?
I have an external USB enclosure that I can't use because I misplaced the AC cord (my bad!)
my question: is there a chart somewhere that shows the different types of power cords for hard drive enclosures (they're the same batch of options for monitors, external CDR burners etc, optical drives etc.)
thanks
Will

I think nerowolfe was referring to the types of AC "mains" appliance power cords, specifically to the connector on the end that attaches to an AC powered device like a computer or power brick. While there are a lot of connectors used for this, there are only a few commonly used in the computer industry. The two most common are the "universal" 3 blade ones used on Mac & most PC desktops & the "figure 8" two pin ones used on many laptop power bricks, as shown below.
It would be no problem to find one of those at a Radio Shack or similar store, but as Network 23 says, most external hard drives use separate DC power supplies, & they can be fitted with one of many types of small plugs. Gumsie's advice more or less applies to these, with the following important exceptions:
• Most drives require DC, not AC power. (Thus the plus & minus polarity markings.)
• The DC power supply characteristics are not completely specified by voltage & current numbers. Some power bricks supply a well-filtered, electronically regulated voltage that doesn't vary with the current drawn from it; others a poorly filtered voltage with substantial AC "ripple" components and/or an unregulated voltage that varies from well above the rated one at zero current down to the rated voltage at the rated current. The second type is intended for devices that do not have critical voltage requirements or contain built-in filtering & regulation. They will most likely damage or cause mis-operation in voltage-sensitive devices like hard drives even if their nominal ratings are correct.
• It is not always easy to tell the two types of power bricks apart but in general the regulated types use switching supply technology & as a result are much lower in weight than the cruder ones, which use relatively heavy iron core transformers. Also, because switching supplies can easily be made that accept a wide range of mains voltages, essentially all of the "universal" power bricks rated for 100 to 220 VAC inputs use switching supplies & often are fitted with a "figure 8" type mains connector so the same brick can be sold in different countries with a mains power cord supplied with an appropriate plug for that country's wall outlets. Typically, cheap "wall wart" supplies like those sold at Radio Shack are not the regulate kind & should be used with caution with sensitive electronics. It is especially important when using them to match both current & voltage rating as closely as possible to avoid the over-voltage problem.
• A few of the more sophisticated external supplies have special features like "fold-back" current limiting. In most regulated supplies, if an over-current situation is encountered, the supply limits the current by reducing the voltage to whatever level causes its maximum rated current to be supplied. This protects the supply but not necessarily the powered device, which may be damaged by a sustained low voltage condition. (This is particularly true for electric motors.) Fold-back current limiting basically shuts down the supply until the over-current condition is corrected, which protects the powered device more completely.
• Because of all of the above, it is always safest to use the power brick furnished as original equipment with the drive or to obtain a new one as a replacement part from the vendor. If you use anything else, you do so at your own risk & you may very well damage the drive if you are unlucky enough to make a bad choice.
• A little humor to lighten this up a bit: Did you know that all electronics devices are really smoke-powered? It's true! This explains why, if you let the smoke out, they quit working!

Thunderbolt Dock for External Hard Drive

Hi there,
I'm trying to find a Thunderbolt Dock for External Hard Drive.
One of these http://www.topbuy.com.au/tbcart/pc/External-SATA-Hard-Drive-Docking-Station-USB- Interface-937p3180.htm
But with Thunderbolt connector instead of USB, Firewire, eSATA etc.
Do these exist?
The only thing I could find close is the Seagate Go Flexi Adapter, but that only works for those drives.
Thanks,
Grant

I would suggest this:
http://www.belkin.com/thunderbolt/
It will do more than you need and require, and you still would need to get an eSATA docking station, but that's what you really want anyways.
Thunderbolt is a bleeding edge tech still (as evidenced but the fact that nobody yet has a good dock for it) but if you go the modular approach you can still pickup your docking station with eSATA and FW800 and USB etc. and take it to a friend's and have more chance of being able to plug it in. and since you're getting a dock and not a drive you want it PC/Mac friendly because you can swap drives to ones formatted for the system. Plus this accessory will be really great if you ever get a Mac Book Air or Retina Display MB Pro that just don't have ethernet or eSATA or even firewire anymore.
And i know that tbolt is faster than eSATA natively, but if you're plugging in a SATA HD then, well i don't think i need to finish that sentance.

How do i protect an external hard drive?

Hi,
Been doing some research and can't figure out the best way to password protect/ encrypt an external hard drive. I know you can use disk utility in os x to create a disk image on the external drive but what if someone plugged the drive into a Windows computer? How does it handle the disk image? Could they access the files on it?
Also, if I had an external hard drive and wanted to partition it but have it protected using a disk image, could I make the entire thing a disk image and then partition the disk image and have everything be password protected? I want to create two partitions... one to clone my system and the other for file storage....is it possible to put these two on a password protected disk image?
So, any other ways to password protect/encrypt an external hard drive?
Thank you..

Instead of protecting the whole drive, it would be better to encrypt just a folder on that drive, therefore allowing windows PCs to place other stuff on the drive.

Backup for External Hard Drive

Hello,
I really love Time Capsule but it's limited in terms of backing up my external hard drive. Basically I have too much data on my 1GB External HD to back up to my time capsule. I'm going to get another external drive to basically act as a mirror to my existing HD. Can anyone recommend software that will back up on drive to another on a scheduled basis?
Thanks,
Tim

The two most common ones are CarbonCopyCloner and SuperDuper. They're most often used to make "bootable clones" of OSX volumes, but work on data-only drives as well. CCC is donationware, so you can use it for a while, then send some $$ so they can keep it up to date. SD has a free version that will do a full replacement, but you'll need the paid version (about $30) to do updates or scheduling. Either is easily found via Google.
Edit: While you're at it, make a second partition on the drive and also make a bootable clone of your internal HD on it. That way, you're protected against a failure of your Time Capsule.

Disk repair for external hard drive

Hi, I gave my son an external hard drive to back up his school work, besides the normal backups of on the Time Capsule. So how he managed to hget the external hard dirve disappear from the screen while there is no back up left on the TC.
I have tried disk utility an number of time on several computers to get the External hard drive working. No luck there. I have tried restore in disk utility, but I cannot get the source and destination righty for a reason.
I have read an advice of Francine Schwieder dating back to 2007 where she advised to run terminator, this is the result I get while the xternal hard drive was connected to my Imac.

With my limited knowledge, was a partition placed on this external hard drive ? I cannot see or acces the external hard drive.
Is there anyone who can help me with this ?
Hope to hear from you.

If you wan to give Data Rescue 3 a spin (I'm testing it out now for the first time) you can get it - and a number of other apps - for $50 from MacUpdate's December Bundle.
Because I have redundant backups, I've never used either DiskWarrior or Data Rescue 3 - but I wanted to try it so that I will be able to know how well it works (or doesn't).

Time Machine Back Up for External Hard Drive Partition

Hey guys,
I have had my imac connected to an external hard drive which runs time machine for some time now (about a year and a half).
I now wish to partition the external hard drive with a Fat 32 section so that I can load data (vidoe's, music etc.) from my windows laptop onto it.
The external hard drive is currently not partitioned in anyway so I will have to create a new partition. Is there anyway of doing this without losing the time machine data already saved?
If not is there anyway of saving the time machine data onto the imac so that when the partition process is complete it can simply be 're-loaded' onto the external hard drive?
Thanks for your help!

Hi, I've been trying to do that: using Disk Utility to create a partition on my EHD that already has Time Machine running on it. My EHD is 2TB and I have deleted last year's TM backups so now I have over 900GB available space on the EHD (previously was 750GB) but when I ran the Partition, after hours of processing ("modifying partition map...") - and I mean like 12 hours no kidding, it resulted in "There is no more space" error! What a waste of time!
Is there any way to find out how much space is needed for partitioning beforehand? I wished DU could tell me that before the "modifying partition map" process begun.
FYI I am running on 10.5.8 and the partition I want to add is to be in Mac OS Extended (Journaled) format, the same with the current format.
Any help is appreciated. Thank you very much in advance.

Which format for external hard drive to use with time machine backup and connect to windows laptop?

Hi! I have an external hard drive on which I have transferred my iTunes library (just mine - not others). I have also a folder containing just films (some but not all of which are in iTunes too) Everything has been working just fine until yesterday I noticed that Time Machine was not including the external hard drive in back up as it wasn't formatted. So I have moved everything back to the Mac hard drive and and ready to format the external hard drive - but understand that if I do the contents cannot be opened from a windows laptop ... is that right? Is there are format I could choose that would allow Time Machine to back up and allow Windows to open as well (the idea being that I take the external hard drive with me on holidays etc!!) Many thanks for any advice.

ok - I understand. I have managed so far to format the drive (on windows) to exFAT file system - which apparently works with both Windows and Mac - but you're correct - it will not be included in time machine backup as I have checked the back up files and Samsung is not showing. Reckon I'm onto having to buy yet another portable hard drive just for windows - or of course buy myself a new mac book!! Can I ask you please - does the drive have to be clear of everything before I change the format - or can I change it with the files still in there? Also, got any quick ways duplicating the files onto another External Hard drive (for use on the windows laptop) At the moment the files are taking 2/3 hours + to copy over! Thank you!

Recommendations for External Hard Drive?

Would appreciate hearing people's suggestions for an external hard drive to use with my current Mac. I see that some brands have longer warranty than others, and some may have bundled software for Mac use, while others don't. Reliability is essential.
I'll be using the the drive to back-up files for safety, documents and especially photos. I think a drive 500GB or greater is probably appropriate.
Eventually I'll upgrade to a newer, faster machine, so buying a drive that works with what I have now as well as the computer I move to in the future would be nice.
Please let me know if I need to provide you with any other information to help you make your suggestions.
Thanks!

dflow:
Welcome to Apple Discussions.
Excellent move. Regular backups is the best thing you can do for your valuable data. A 500 GB HDD will give you plenty of space for quite a while. You want to be sure to get a drive with an Oxford chipset. The firewire bridge is usually the first thing to fail in a firewire HDD, and the Oxford chipsets are the most reliable available. The previous poster mentioned OWC. I agree. The Nepune is their economy version, but a very reliable drive. The better quality Mercury Drives offer a wider range of options and the same rock solid reliability. You can choose Firewire or Firewire/USB, as well at Firewire 400/800 depending on your computer.
Once you have the HDD you will need to format and partition it, but more of that later. Look through the offerings above and post back with questions.

LaCie d2 Quadra or OWC Mercury Elite Pro for external hard drive?

Using Intel IMac,10.8.3 and replacing my external hard drives. Had posted before and had some issues with other drives and narrowed things down to these two drives. Using one for Time Machine and the other for CCC.
I would appreciate any and all comments from users of either of these drives and any suggestions!?
Thanks,
Don

I vote for the OWC drives. I have 5 of them and am very happy with their performance. The one LaCie drive I had a couple of years ago had to be replace. It was replaced with an OWC drive.
