Second Backup Drive Cannot Be Repaired

My second backup drive (LaCie 1TB) reads the following message after scheduled backup failed and I ran Disk Utility:
Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is this drive shot or can I reboot, clear and refill, etc? What exactly would be the next best step?
Since this is my second backup drive, I have some wiggle room...
Thanks!

Copy what files you can to another drive. Then partition your drive using Disk Utility. Launch disk utility, selecting the external drive name (not the indented volume name) and click the partition tab. Toggle "current scheme" to 1 partition, click "options" and pick the GUID table and apply changes. Acknowledge the warnings about erasing the drive.

I keep getting an error message that says that the hard drive cannot be repaired. Therefore I cannot get the computer to start up.

It doesn't sound like you are doing anything incorrectly from what I can see. Have you tried restarting the iPad and then see if you can backup?
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

Time Machine won't allow second backup drive?

I want to create a second backup of Time Machine on another external hard drive. However it won't give me an option to backup to both drives. When I insert drive II, it only allows me to use it if I delete backup drive one. I attached photos of the prompt.
Any help appreciated greatly. Thank you :-)

Howdy Kgkgkg12,
It sounds like this drive you are wanting to use with Time Machine is not in the same format that Time Machine needs to operate. According to this article:
Mac Basics: Time Machine backs up your Mac
Your Time Machine drive needs to be formatted as Mac OS X Extended (Journaled). If you select an NTFS or FAT-formatted drive, Time Machine prompts you to reformat the drive. Important: Reformatting erases any files on the destination drive. If you're not sure if you want to erase the drive you connected, choose a different drive.
You can check the format of the drive with these steps:
OS X Yosemite: View file, folder, and disk information
Get individual item info: Select the item(s), then choose File > Get Info, or press Command (⌘)-I.
Thank you for using Apple Support Communities.
Cheers,
Sterling

Hard drive damaged and cannot be repaired

I have had a few weird issues with my early 2011 macbook pro 13 inch, updated fully. All of this started after ML. Sometimes, when I power it up there will be a pause and then the signin screen will appear. If I sign in then, the apple logo and the spinning wheel beneath it will appear as usual, however, it will never login, it will just remain that way indefinitely. Also, sometimes when I shutdown, the grey wheel will appear for about 15 seconds and then the computer will shutdown. Therefore, I decided to do a reinstall of Mountain Lion. It took about 3.5 hours and finally it gave a warning message saying, "installation failed, the hard disk is damaged and cannot be repaired. Restart to try again." I restarted and the same thing accured at startup, same message.
When I restarted in disk utility, the Machintosh HD was not available. When I used disk utility application, the verification said, "disk is damaged, click repair disk", but that option is greyed out. I reset PRAM and nothing changed. My verification is still returning errors and 'damaged disk" but not way to click 'repair'.
Also, for most of the time I have had my laptop, moving slightly or lightly bumping the lower, righthand corner of the body makes a clicking noise, almost like sticking a stick into a moving fanblade, but not very loud. This does not occur now as much as it used to though.
Is there anything I can do short of replacing my HDD, although I would be interested in upgrading to an SSD at some point.
Thanks!

It's very unlikely you'll be able to fix that without erasing the drive.
Do you have backups?

There's a very small chance you can start from the Recovery HD and repair the disk from there. It's probably worth a try. See the yellow box in #6 of Using Disk Utility.
If that doesn't help, see the pink box there. If you want to try DiskWarrior, you'll need to borrow a working Mac to download it and put it on a DVD or disk partition.
Otherwise, your only choice is to erase and reformat it, then download a fresh version of OSX (although it sounds like it may be failing -- the clicking noise). You do that from the Recovery HD, too; see the yellow box in #1 of Using Disk Utility.

Is it possible to have two hard drives connected to my airport extreme and use one to store my itunes library/iphoto and the other to backup via time machine? Will the second (larger) drive back-up both my mac HD and my other external airport drive?

For the past year I've been using an external hard drive (HD1) connected to my airport extreme as the back-up location for time machine. This has worked fine without any issues. What I would like to do now is to move my itunes and iphoto libraries off of my laptop (space constraints) and store them on a second external hard drive (HD2) connected to the airport extreme. I have successfully connected the second hard drive using a Belkin powered USB hub. What I am wondering is if I direct my time machine back-ups to HD1 will it back-up both my mac HD as well as HD2? I apologize if this has already been answered but i've read conflicting responses on various message boards and a number of responses were dated so I wanted to make sure I received the latest information.
thank you

That may be true, but you need to know that backing-up that way is unreliable and not supported by Apple. See: Using Time Machine with an Airport Extreme Air Disk. Do not be surprised if those backups suddenly turn up corrupted.
What I am wondering is if I direct my time machine back-ups to HD1 will it back-up both my mac HD as well as HD2?
No. Time Machine cannot back up from any network location. The 3rd-party utilities CarbonCopyCloner and ChronoSync may be workable alternatives.

How do I repair a damaged time machine backup drive/remove pictures from library on locked/failing external drive

I have a WD 1TB external hard drive that I use as my time machine backup drive as well as to store a number of things including my iphoto library (due to its size of about 85 GB) as well as documents. I began using the WD 1TB external drive with my 2007 13" MacBook and when I purchased a brand new 13" MacBook Pro in 2013 I used the WD to transfer what I wanted to the new laptop. My new MacBook Pro is running OSX 10.8.4 (2.9 GHz Interl Core i7 with 8GB 1600 MHz DDR3) (not the retina display). The WD 1TB product # is WDBACX001... and it's only about one year old so I'm super bummed that it's failing and trying to take my life with it It has only ever been used with my two MacBooks, never with a PC.
The external WD was working fine until this week when I noticed that it wasn't appearing on my desktop. I rebooted, unplugged and replugged the WD drive in each USB portal, and still nothing. I ran Disk Utility to verify and repair the disk, which did force it to show up on the desktop again, though it made everything painfully slow. After running the repair function Disk Utility told me that the drive couldn't be repaired, and that I should backup whatever is on it and restore the WD drive. I managed to pull off most of the documents before it decided to freeze up my laptop (I had a couple of folders with a few documents each left), but I wasn't able to move the iphoto library over before the drive disappeared again. I got it back by running the repair option in disk utility, with the same message that the WD drive is failing and to back it up, and tried to move the iphoto library. It told me it would take 180+ days, and kept going up. I left it up anyway for about a day to see if it would change, and instead it gave an error message, and moved nothing. I can't open the library in iPhoto- it tells me it's on a locked disk. I checked the permissions and it's set to Read & write by me (the admin user) but then under that it says read only for "everyone." I can't get into the library to pull out my pictures, which I cannot afford to lose.
I would appreciate any help or advice on how to crack into my iphoto library on this failing drive to remove the pictures. I read a lot about DiskWarrior but I also read that it won't work on newer macs (anything after June of 2012 supposedly), so I'm wondering if that's true or not, and if not is that a good program to use?
I can't afford to take it to a professional right now, so any help or advice would be so greatly appreciated! Also if anyone then could suggest the best way to back up in two places (digitally and perhaps a better brand of external drive) it would be amazing.
If you need more info let me know!

If you're very lucky, you might be able to salvage the drive mechanism, and the data, by removing it from the enclosure and installing it in another one, or in a drive dock.

Since installing Mountain Lion, Time Machine says says that my Free Agent Goflex (Seagate) external 2gb drive cannot be used as it is read only. I tried disc utility to repair permissions but that block is greyed out. The disc verifies as being OKI What next?

Ok, I solved this problem! I ejected the drive and then disconnected it both from the power supply and the USB connector. I then reconnected everything and powered it up again and Then went into TM preferences and chose the drive as the backup. TM did a new backup (well over an hour) and now works as advertised.

Cannot find a mounting to install a second hard drive in my Qosmio x70-A

I have looked all over the internet and have gotten no where in my search for a mounting for the secondary hard drive bay in my laptop. Anybody know where I can get one?
Also I've included pictures of the secondary drive bay and the primary bay. From the looks of it I can't use the same type of mounting in the secondary bay as in the primary.

I have the same issue, and have found Toshiba support to be completely unacceptable on this.
After getting bumped around from sales to tech to sales because "we don't answer that question, you have to talk to the other guy", I finally got a "straight" answer from sales:
"Sir, we DO NOT sell that part, and therefore I CANNOT tell you a part or model number for the part you may need to install that second hard drive. The only thing you can do is talk to our parts supplier over at National Parts (1 800 524 8338) and ask them to provide you with the model numer or sell you the part."
At this point, I was annoyed, but thought that at least with a straight answer I could proceed.
After a very short hold time with National Parts, a very kind associate answered the phone and listened to my tale of woe. Unfortunately, she was unable to help and said:
"Unfortunately, sir, I have listed that while there is no caddy for the second hard drive slot on you X70-A specific model, there is supposed to be a mounting bracket. Unfortunately, we have been trying for MONTHS to have Toshiba give us the part number, spec, or any other information other than 'mounting bracket', and therefore I'm afraid we have neither a part to sell you nor a part number for you to go looking for one".
At this point annoyance is full-blown anger. How is it possible for Toshiba to make something that should be SO SIMPLE so VERY VERY VERY complicated and impossible.
"Sorry, if you didn't want to spring for the dual drives when you bought it, you're hosed forever sucker." Does not seem like an excellent customer service strategy.
This was the FIRST Toshiba I'd ever decided to spend my hard-earned money on, and now it's a machine I can't upgrade because they can't get their act together with their parts supplier or in-house over a 3 dollar bracket?
UNACCEPTABLE.
The pictures the original poster shows are exactly what I have, no need to add more o fthe same.
ANY help, Toshiba?

Using a Second External Drive For Time Machine Backup

I have been using Time Machine for almost a year and the external drive I'm using is almost full. Can I switch to a second external drive? If I decide to keep using the same drive is there a way to keep my original backup? Is there information that I need from that first backup that I did?
Thank you!!!

Yes, if that's what you want to do (see below). If you start "fresh" on a new drive, your first backup will be a full one; everything on your system. Or, you can copy your current backups to it via the procedure in item #18 of the Frequently Asked Questions *User Tip* at the top of this forum. TM will then continue making it's usual "incremental" backups, and you can erase the old disk and use it for other things.

Probably not. As Mr. Peck noted, TM will automatically delete your oldest backups when it needs room for new ones (unless you have the +*Warn when old backups are deleted+* box checked in TM Preferences > Options).
But unless you've been deleting things from your internal HD, counting on TM to keep it's backup copies indefinitely, you won't lose anything you need.
That's because of the "magic" of Time Machine. Each backup is an "incremental" backup, copying only the items that have been added or changed since the last backup. But by using "multi-links" to the backups of items that did not change, each backup is, in effect, a full, complete copy of your entire system!
So when TM deletes your oldest backup, all it will be deleting are it's copies of things you changed or deleted long ago.

I cannot install Lion to a backup drive for my new Mac Mini

I just bought the new Mac Mini with an i7 processor last week. I wanted to format a backup drive for it. When I tried to use the Lion Recovery partition on the new Mac Mini, I keep getting an error message that says it's incompatoble with the current model.
I also tried to use the Lion thumbdrive I purchased from Apple to see if that can be used, but it also give me the incompatible message.
Is there a special version of Lion that's only for the new Mac Mini's?
Any help is appreciated!

I had to replace my hard drive twice in my power mac g5. Luckily, I had the foresight to install a backup drive the second time around. Has anybody had HD problems? Is it the Power Mac or I just lucked out on some bad drives.

Hi Leon,
There are many well known G5 problems, but being hard on Hard Drives is not one of them.
