Restore a external hard disk

Hello,
Can I restore old rman backup on external hard disk with USB3? the size of database is 430 GB.
Thank you.

I have never tried but I would hope the answer is no.I have done it, and the answer is sadly 'Yes' ;-)
RMAN doesn't have any opinions on where you restore your backups, as long as the disk area is addressable in your system (i.e. mounted with a path/letter, depending on your OS).
But on the other hand, I wouldn't do this on a production system, only for backup/recovery verification/development system creation.

Can't get external hard disk icons to appear on iMac desk top

Hi guys,
I hope someone can help me. I have OS X Lion on my iMac. I noticed that a few days after installing it, my external hard disk icons and Macintosh HD icons disappeared from the desktop. I tried going to Finder- Preferences- Show these items on desktop and checked the appropriate boxes but this only restored the Macintosh HD icon to the desktop. Checking the "External disks" box makes no difference. When I open Finder I can see the external hard disks in the sidebar so I don't think there is a problem with the disks. Can anyone advise me on how to restore the external hard disk icons to the desktop?
Thanks a million

I'm not sure why they're not showing but try doing a couple of troubleshooting steps. Restart the machine in the Restore Partition, when you hear the startup tone hold down the Option key and choose the Restore Partition. Then open Disk Utilities and Repair Disk Permisssions on your internal HD at least 2x, while you are in DU it wouldnt hurt to run Repair Disk, again 2x. Then restart the computer in Safe Mode to clear some caches and finally restart normally and check.

Disk write cache corruption on an external hard disk

Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.

Disabling a write cache would not help you with the problem you are having. Besides the write cache is on the hard drive and operates independently of the operating system. But nothing can protect you from disconnected an external drive improperly, and if the drive is in the process of being written to, and the problem comes from directory corruption, not file corruption, as in the case you have described, disabling a write cache would not have made any difference.
For the future the magic word is: Backups.

I currently have a MAC Mini, which has 1 Firewire 800 port. I have a 1TB external hard disk that runs at Firewire 400. Can I insert another external hard drive that runs at Firewire 800?

Here's the deal. Currently running SL 10.6.8 on a MAC Mini. Planning for eventual upgrade to ML. Have a 1TB external hard drive partitioned into two volumes, one volume for Time Machine and one volume for SL which I periodically update using Superduper. Thus I always have a point-in-time bootable backup on the external hard drive.
The MAC Mini supports Firewire 800. However, booting from my current external hard disk is pretty slow, since it only supports Firewire 400. I am considering buying an Iomega MiniMax which supports Firewire 800. Then, I would use the MiniMax as my bootable backup volume, and relegate the older hard drive to Time Machine.
So, question #1 is, can I daisychain the new MiniMax between the MAC Mini and my existing external hard drive? My expectation is that the new Mini Max would run using Firewire 800 and that the existing hard drive would run at Firewire 400 speed as it does today. If it doesn't (e.g., daisychaining in the Firewire 400 external disk with the MiniMax Firewire 800 external disk ends up running the whole leg at 400), my resolution will be to run the existing hard disk off an available USB port and have just the MiniMax running at Firewire 800.
Why am I going to all this trouble? That's question #2. I don't trust upgrades; they always break something. When I upgraded from 10.5.x to 10.6.x, the web directories got renamed, and all of my web apps 403'd until I figured out what happened. Plus, I have accounts for other family members, and in order to ensure their ability to use the computer during my upgrade process, I need to have the ability to fall-back quickly to a known-stable version of OSX. So what I'm trying to do is insulate myself from problems by partitioning the MiniMax into two volumes, taking a Superduper image of my current installation on the Mac Mini to MiniMax external drive volume 1, then upgrading to ML on the MAC Mini, and take a SuperDuper image of that to MiniMax external drive volume 2. Then, if the upgrade results in problems I can't resolve immediately, I can simply reimage the MAC Mini from MiniMax volume 1. BUT ...
... I've read that the ML installation creates a "service and support" partition that is different than the startup disk. I'm concerned that I won't be able to reimage the hard disk in the MAC Mini once I upgrade it to ML because of the partitioning changes it introduces on the startup disk. Theoretically, I +should+ be able to use the disk utility on my SL system to repartition the disk in the MAC Mini prior to reimaging it from my backup, but I'm considering the possibility that the new partition may be of a type that the SL disk utility cannot identify, and might therefore be unable to delete or even detect. So I'm hoping someone else has been down this road and can advise me. Even at Firewire 800 speeds, booting from an external disk is still going to be slow, so I want to be able to restore my SL image to the MAC Mini hard disk.
A little background on me. I work for a major disaster recovery provider. I used to have a Mac PRO G5, which I got used, and the first thing I did with it was install a second hard disk, SuperDupe an image from the first disk to the second, and made sure I could boot from the second. THEN I started using and customizing the MAC. I really feel vulnerable with the MAC Mini, since it only has the single internal hard drive - sort of like going out in public dressed only in a long T-shirt. So my whole thing is, I ABSOLUTELY MUST BE ABLE TO PUT THINGS BACK THE WAY THEY WERE before I do the migration to ML.
Obsessive-cumpulsive? Yep. Anal? You got it. That's why I'm in the DR business.

You may have overloaded the port, following the instructions below it should reset:
+1. Shut down the computer.+
+2. Disconnect all devices and all other cables, except the keyboard and mouse cable(s).+
+3. Disconnect the computer from the power outlet and wait for 3 to 5 minutes.+
+4. Plug the computer back in and turn it on.+
+5. Reconnect the device(s) (one at a time if there is more than one) and test. Test with each port if you have more than one.+

External hard disk not recognized by time machine

I have an external backup disk, Passport, that is no longer recognized by time machine or my computer. I used it a couple of weeks ago to restore my wife's MacBook. Hers is an older model and uses Lion. Since then my MacBook Pro--mavericks will not mount the external hard disk.
OKAY==after leaving the Passport on for a couple of hours it now is mounted. Don't know what happened, but it is now working.

I see it's now working but make sure you are running the latest version of WD software.

Recovery from external hard disk

Dear Hp representative,
I have copied recovery file from recovery partition to external hard disk.
After that, I have deleted recovery partition and now I can't restore computer to factory settings.
I have tried to make new recovery media but it says that recovery partition doesn't exists although I have made new partition and copied the recovery file to it.
Please help.
Thanks
Karlo

For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
Unfortunately coping the partition does not work. I don't thing you will be able to create recovery media from the copied partition on the external but if you have not yet created recovery disk you can give it a try.
If you cannot create the recovery media you will need to contact HP support to obtain a recovery kit.

How do i back up my imovies on an external hard disk?

Hello
i am trying to back up my imovies on a external hard disk
, i follow the instructions but everything is still in my computer!!
and now when i open updates project ,they are empty!....

Command + R for OS X Recovery is for restoring from a backup.
You need to repair the startup disk.
Startup your Mac while holding down the Command + R keys.
From there you can access the builit in utilities to repair the disk.

Can't erase anything on an external hard disk partition of bootable backup ____error message -50 "Error in user parameter"

I am using MACOSX 10.6
The data on the disk partition on my Iomega 2Tb external hard disk drive (labeled "Bootable Backup") was written by Carbon Copy Cloner (CCC ver. 3.37)
I have had problems with overwriting this using CCC, and I have also had troubles changeing the data on my "Versioned Backup" partition, using either CrashPlan or CCC
A third partition that was virgin ("Half-Tb Volume") on the same external disk drive, however, DID accept the latest CCC bootable backup of my Macintosh HD...which is the reason I want to recover rthe space on the first bootable backup partition.
I have not found any links to this error using Google search, apart from the definition.
Anyone

Do a backup using Time Machine or a clone. Then boot into the Recovery Volume (command - R) on a restart. Run Disk Utility Repair disk. If it can't repair the disk, then select the erase tab and reformat using Mac OS Extended (Journaled). Also click the Option button and select GUID. When complete, reboot normally and restore your data.
Please update your profile to reflect the OS you are running.

The iMac doesn't recognize my external hard disk

My iMac doesn't recognize my external hard disk. The iMac also keeps a DVD inside. It doen't throw it out despite "eject".

Sounds like you might need to make that call. In the meantime here are a few of things you could try that may help:
To eject the disk try a restart holding down the mouse button - hopefully it'll eject.
If you are running either Mountain Lion (10.8) or Lion (10.7) try booting into the Recovery HD:
Restart holding down Command+r. At the screen with 4 choices choose Disk Utility and then select Macintosh HD and click on repair disk. If it fixes anything click on repair disk again until you get a clean pass. Restart as normal from the Apple menu.
If you are running an earlier OS you would normally carry out this process by putting the grey restore disk that came with your Mac in the Disk drive and restarting holding down the C key. Choose your language and at the next screen from the menu bar select Utilities>Disk Utility and then follow the above instructions (I realise you won't be able to do this if you have a disk stuck in the optical disk drive).
Try an SMC and PRAM reset: https://discussions.apple.com/docs/DOC-3603
Try a Safe Boot: Restart holding down the shift key until you see a grey progress bar. Once it's booted restart as normal from the Apple menu.
If none of this helps, I guess you need to make that call. Good luck.

How to make a bootable backup on external hard disk?

Hi guys, I want to ask how can make a backup of entire C(windows) drive on my external hard disk.I tried using backup option in my transcend hard drive
software but it gave me some errors..So I used backup option C:>properties and made a backup on my hard disk.But I am not sure if I can restore from it if my windows crashes coz I don't know if I can use this backup file from boot.So here's what I need
1)To make backup in hdd without having to wipe the it.
2)To make the backup bootable incase my windows crashes, I should be able to restore all my C drive..

Hi... I agree with your Number "2". I think that it is much better for you to install a backup tool e.g.aomei backupper (http://www.backup-utility.com/features/) and to forget about any possible troubles at all as the tool will backup everything you need and how you need, creating the whole image of the disk c which you can easily restore in case you have the crash.

Restoring an external hard drive with time machine

I'm having a problem restoring an external hard drive using time machine. I'm on a macbook Air Running 10.7.5.
The external hard drive where I store all my photos crashed a few days ago. Not a total disaster, because it's backed up, but I can't figure out how to restore the drive onto a new hard drive. When I go into time machine without the corrupted drive attached, it does not show up in the time machine browser as an option for restore. (The files are definitely there, though, because I can see them when I look at the time machine files in Finder. I'm afraid if I just transfer the files by dragging, though, I'll mess something up.) I tried using the migration assistant, but I'm having the same problem there.
Anyone know how to do this? I'm a little frantic to get my photos back.
Thanks!

I am having a similar problem. I use a Lacie external hard drive connected to an Airport Time Capsule via USB to store my itunes library. Yesterday I disconnected the external drive from the ATC and connected it to my macbook pro via fire wire to transfer 40 gigabytes of media files from my laptop to the external drive directly rather than over wifi. When I reattached the external drive to the ATC the Lacie drive didn't show up even after rebooting everything. I then disconnected from the ATC and reconnected to the laptop and now I get an error message saying the Lacie disk is unrecognizable and needs to be reformated. The Lacie drive was being included in the time machine backups so the files should be available through time machine but I don't see anyway to access them because the Lacie disk icon doesn't appear in the time machine backups. Is there another way to browse the files?
I have had issues with Lacie disks not showing up on the desktop before, particularly when transferring files from one computer to another. The transfer usually goes fine but then when I reattach the drive to the first computer it isn't recognized anymore until I reboot and it sometimes requires a couple of reboots. I initially tried to connect the external drive to both the ATC and the laptop but that didn't work, although now I'm wondering if that was because the connection to the laptop was firewire rather than USB like the ATC. In any case I currently have over a terabyte of data on my lacie that I can't access which includes my entire itunes library and backup files from multiple computers which were "cleaned" but not restored.
Disk utility sees the drive but can't verify or repair and tells me to backup as many files as possible and then reformat. Unfortunately I can't see ANY files to backup because the disk won't mount anywhere. If anyone has a recommendation for utilities to recover the files I'd be most grateful to get them.

Iphone backup to an external hard disk

I'm currently using a Mac Air with very limited internal hard disk space (60.7GB). And after all applications installed, I'm left with hardly less than 10GB, not enough space to backup my iphone and ipad.
How can I point iTunes to store my iphone and ipad backups to my external hard disk, and to restore from it?

I am using Windows 8.1 i have an External Hard Disk and one drive is now inaccessible due to sudden power failure few days ago. Now it shows "Data error (Cyclic redundancy check)". I want all my important files and Pics. How ?

Hi,
I am using Windows 8.1
I have an External Hard Disk i have partitioned it to 4 parts.
One drive is now inaccessible due to sudden power failure while listening Music from that drive few days ago.
Now it shows "Data error (Cyclic redundancy check)".
I tried all the procedures provided here like
chkdsk /f, diskpart, rescan etc
but no result :( (i mean all processes failed. They could not detect the drive).
Please help me to get those data, pictures and project files.
thank you

How do i retrieve file vault protected files from an external hard disk that used to be my mbp's hard drive? the hard disk got corrupted and will no longer boot. I put it in an enclosure and attempted to copy my files but failed because of FV encryption.

This external hard disk used to serve as the main drive of my mbp. It got corrupted and the OSX would no longer load. I upgraded to a 500gb hd and used the old hd as an external drive. I tried to copy my files but i could not access them because of the filevault encryption. 110gb of hd space appears as used which means that my files are still in the drive. Is there a way to retrieve these files? thanks

According to your post, you're using Leopard, so FileVault only encrypts your user folder (unlike Lion). On the mounted external drive, in your user folder, you should see a file called username.sparsebundle, with username being your user name. Double-click that file to open it and it should prompt you for a password. Type in your password and the file will mount as a volume in Finder. You should be able to copy all of your files over.
