Problems with repairing external HD for use with TM

I've been trying all day to fix this. It was working earlier no problem, then when I went to restart my computer(after reinstalling mac osx) due to updates, i've been having trouble ever since. It doesn't mount, but yet it shows up in the disk utility. I've tried to repair it, and I get this:

Any suggestions or ways to fix this? All my files are on this HD...

One of the things you listed is a case-sensitive filesystem which can be troublesome.
Run DU and look at your internal HD.
Click on the partition and down below you will see Format: Mac OS Extended (Journaled)
I believe that it will also say "Case Sensitive" if it is.

I have just bought an HP Photosmart D110a for use with iPad 3G but this printer could not be connected to Internet, can anyone tell me what the problem is?

Hi,
Do you follow the setup guide ? What is the error ? Looks like your printer is not Airprint ready therfore you need to set it up for ePrint.

External HD for use with Time Machine

I have a new MacBook Pro with 320GB HD. I want to buy an external HD to use with Time Machine for a back up. HOw much capacity should I be looking at for the external? Is 500GB enough or is it possible to partition a 1TB unit for use as backup and extra storage (photos, music, etc...)?
Thanks.
This should have been posted in the late model forum. Sorry.

Can I use disk utility to partition once plug in HD?
Yes, you can. Click the Partition tab. Click options and set the partition scheme to GUID. One option is to have one partition a bit smaller than your internal HDD, which you can use for a bootable clone (SuperDuper or Carbon Copy Cloner).
See this post for a great discussion of backup strategies:

Convert IDE 2.5" external enclosure for use with SATA hard drive

Hello all,
I recently upgraded my Macbook hard drive and ordered a 2.5" enclosure at the same time for use with my old hard drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16817347007). As soon as I opened it, I noticed that the pins don't line up and have now learned about IDE vs SATA in the forums. Okay, is there anyway I can still use this enclosure? An adapter?
Thanks,

Format external drive for use with both Leopard & XP, & maybe Win7

I want to repurpose one of my old small Firewire drives to use with both Leopard and XP via Boot Camp on my MacBook. It is is 60GB and is currently formatted with MacOS Extended Journaled, and Apple Partition Map. I don't think I will have any need at the present time to store files of more than 4GB on it (most of the ones I want to store are no more than a few hundred MB each).
Is using FAT32 with Master Boot Record adequate? Up until now I have just used flash drives for external Windows storage, but I would like to consolidate lots of topographic maps files onto this one Firewire drive instead of using multiple flash drives, and use these files with both Leopard and XP. If I want to try Windows 7 in the future via either Boot Camp or virtualization, will there be a problem with FAT32/MBR?

Hi,
using FAT32 as file system and MBR as partition table should work just fine with OSX and all Windows versions up to 7.
And since your files don't come close to 4GB single-file-size, that FAT32 limitation is no hinderance.
Use Disk Utility to do this, since Windows won't format partitions/drives with more than 32GB to FAT32 (built-in limitation).
Nonetheless it can use such partitions (I have a 200GB on my external HD).

Advice - External HD for use with Time Machine?

Hi,
Just wanted to know what's best for me to buy. Looking into what's available has only made me more confused...
I want a HD that:
- Works well with Time Machine and my Macbook
- Will copy everything from my computer rather than drag-and-drop or manual file choice (although that's more the program I use than the HD itself, right; Time Machine does that as far as I know?)
- Enough space for all of my video files from my video camera (there's quite a lot of them)
I want to start deleting some video files from my computer and my video camera but I don't want to lose them, so that's the major use really. As long as they'll all fit and if I want one back on my computer again it'll be easy enough to find it and put it back on...
Any ideas? Keep in mind that I live in Perth, Western Australia...
(And I apologise for the ignorance/lack of proper techy terms!)

Hi Eleanor,
I'm from Sydney so it's great to see another Aussie on here! Welcome to the forum.
Just a couple of points that I would keep in mind in addition to the correct advice already given:
Apple recommends having a dedicated drive for Time Machine, so ideally you wouldn't use it for anything else. Also, as a guideline, they recommend having a Time Machine drive at least twice as large as the primary drive in your computer so that enough space is always available. The more space, the further back your backups will go before needing to be written over.
You can put other stuff on the drive but ideally it's better (if your budget allows) to get a second external drive for video camera files and the like. Those video files also grow pretty big as you've probably noticed, so they will need room to move as well. External drives are cheaper than ever, so two drives is the best bet.
One final recommendation/option is to go for a Time Capsule as your Time Machine drive. The benefit here is that it works wirelessly so you won't have to plug it into your USB/firewire port at all. It just backs up without any action from you whatsoever, which is what makes it ideal. If you don't yet have a WiFi network, here's your chance to dive in. If you do, it's a natural fit for your network.
So my ultimate recommendation is: 1) Time Capsule 2) USB/firewire drive.
I hope that helps!

"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." Trying to format my iomega external HD for use with Mac

Hi. Trying to connect iomega ext. HD. i have to reformat for Mac. When i plug in & go to Disk Utility,the external shows up and i'm supposed to click "partition". When i do, a box comes up saying ""Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." I quit and relaunched, same results. After googling my question, i came up with this:
"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility."
(Quitting and reopening Disk Utility does not help.)
The following also appears in Console log:
*** malloc[419]: Deallocation of a pointer not malloced: 0x290a410; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug : for architecture i386 object: ./Applications/iTunes.app/Contents/MacOS/iTunes malformed object (unknown flavor for flavor number 0 in LC_UNIXTHREAD command 27 can't byte swap it)
Workaround
Quit Disk Utility.
From the Finder's Go menu, choose Go to Folder....
Type the following, then click OK: /Library/Receipts
Temporarily remove these iTunes receipts from /Library/Receipts (sort the folder alphabetically as a list):
iTunes.pkg
iTunes4.pkg
You can put them on the desktop, for example. Do not remove iTunesX.pkg or iTunes Phone Driver.pkg.
Open Disk Utility and repair disk permissions again.
Quit Disk Utility.
Put the removed iTunes receipts back in /Library/Receipts.
Note: This issue does not affect Disk Utility's verify or repair disk features.
All seemed good, for a moment, until, upon going back to Disk Utility after removing itunes4.pkg and putting on desktop (i did not have itunes.pkg to remove) the same thing was happening. When i highlite my iomega ext. on left of page, disk perrmissions is grayed and does not allow me to click on it. Same problem from the start. Can somebody please help me out here? That would soooo awesome. Thanx!

i'm just scared i will do something wrong on my own and lose my data.
You shouldn't be scared of that, because you should already have backups. If you don't have backups, then backing up is the first priority.
Insert the Snow Leopard DVD and restart. When you hear the chime, hold down the C key and keep holding it until the Apple logo appears on the display. You should now see the language selection screen. Select your language, then choose Utilities > Disk Utility from the menu bar. In the Disk Utility window, select the external drive (not the internal). The drive may already have a data partition, in which case there will be another icon below the drive icon. Choose the drive icon, then select the Partition tab. Create a single partition with the default options (GUID partition table, Mac OS X Extended Journaled).
When the partitioning is done, select the startup volume on your internal drive in the DU window. Select the Restore tab. Drag the icon of the startup volume to the "Source" field. Then drag the icon of the newly-created volume on the external drive to the "Destination" field. Make sure you have this right. Then click the Restore button, and the data on your startup volume will be copied to the external drive.

Question about Formatting Buffalo USB 1TB external drive for use with Mac Book Pro Mountain Lion HD

Hi there, Have Mountain Lion HD operating system (not sure if it is 10.8 or 10.8.1. or 10.8.2) and have a Buffalo USB 3.0 1TB hard drive. When go to utilities to try and format with Mac OS extended, following 3 files show. DriveNavi. exe, Slm.exe and Mac. The option to left click and erase menu is not there. Or at least not as shown in all the help videos.
It is USB connection so will take ages but want to use drive to store video footage and also partition to back up Time Machine. ( travelling in South America and no other Ext Drive option available too buy) how much space should i assign to Time Machine when partitioning? Is there anything else i need to think about? as new to formatting. Any thing else i can do to make process of transfering footage to Buffalo quicker?
Final question is if it is finally reformatted am i going to have to spend so long accessing footage from hard drive when back home and editing that it really is not worth if, and i should just write this off as an inappropriate purchase, and try and buy more memory cards and not bother with transfering/storing? Thanks in advance for time spent trying to assist.

Use Apple's Disk Utility in the Applications/Utilities folder to format the drive.
The programs on the drive given to you by the manufacturer is likely backup software (or malware) and essentially worthless, it will be wiped when you format the drive.
I do NOT advise you partition that drive for TimeMachine, rather I advise you not to use TimeMachine at all for your purposes because TM is just a backup, not a bootable drive.
Rather do this.
Get another hard drive that is equal to or slightly larger than your boot drive.
Format the drive in Disk Utiltiy > 1 Partition, option: GUID, Format: OS X Extended journaled, click Erase and move the slider one spot to the right and click Erase. This will take some time as it's going to map off any failing sectors it can BEFORE you lay data on the drive corrupting it.
Next, pay for and download Carbon Copy Cloner, use the default settings and simply clone internal drive to the external drive. this will also take some time the first time.
Next use Disk Utility to Repair Permisisons on both drive. Now reboot the machine and hold the option key down, you can select the external drive clone to boot from!!
You can update the clone the same way by using CCC, but it doesn't take as long, only copying changes.
This is better than TimeMachine as a bootable clone is bootable in case your internal drive fails to boot the machine.
Use the first drive for storage and be very gentle with it while it running, like you should do for all hard drives as they are subjective to shock damage.
The objective with the clone drive is you keep it safe, and not carting it around where it can be more subjective to damage like the other drive will be.
Remmeber you need 2 forms of hardware backup at all times.

Format external HD for use with Mac Network and PC

System config: Home network: Mac Pro & MacBook Pro connected via AirPort Extreme. Both run OS X 10.5.6. The Mac Pro also runs Windows XP Pro. Work computer: Dell, Latitude D830 running Windows XP Pro.
Situation: I have a Western Digital WDMT5000TN 500GB Portable HD, (FireWire 800 & USB). The WDMT5000TN came formatted Mac OS Extended, which, as I suspected, could neither be read nor written to in XP. I reformatted the drive NTFS in XP Pro. This worked well with XP but was read only in OS X.
Ideally, I would like to format the drive so that it is both read/write capable with both OS X & XP Pro and handle file transfers in excess of 100 MB. If this is not possible my second choice would be to have the drive read/write OS X & read only XP, given that I upload mostly in the Apple domain & would be able to perform backups of it’s contents using Time Machine with OS X.
If anyone has a formatting recommendation or related information that may help I would appreciate your insight. Thank you.

Two basic options:
1. Format the drive FAT32 (MS-DOS) which is read/write on both Windows and OS X.
2. Leave the drive formatted NTFS and install software on OS X to enable read/write access. The options are: a.) Paragon NTFS for Mac OS X - 6.5.1; b.) MacFuse and NTFS-3G 2009.2.1u1; and, c.) NTFS for Mac 1.0.

Sharing External HD For Use With Time Machine

Hi,
I have a home network with an iMac and two MacBooks. I have bought an external HD in order to set up Time Machine. My hope is to leave the HD connected to the iMac and then to mount it via the network to the MacBooks so that Time Machine can back up to there.
Is there a simple way to do this ?
Steven

There's some advice on that in item #4 of this post. It does seem to be pretty simple. You'd need to use the Sharing panel of System Preferences to start sharing that disk. What part of the setup process do you expect to give you trouble?

Copying Time Machine files to external drive for use with PC

Hello! Any help with this would be greatly appreciated.
My MacBook Pro recently died. I have it backed up by Time Machine on an external drive. Now I'd like to copy my files from the backup to another external drive so that I can access them later from a PC computer running Windows (7 or 8). Is that possible? The Time Machine drive, I believe, is formatted specifically for Mac, but the external drive I'm trying to copy to is FAT32. Can I connect both to a friend's Mac, look for the files I need, and then copy them from the backup drive to the other external drive? Will a PC computer be able to read them?
Thanks!

Usually that error indicates a drive malfunction; specifically, the drive is spinning down and not responding to bus signals. Some "Eco" or "green" drives are known for this behavior. The following steps may help:
Select  ▹ System Preferences ▹ Energy Saver ▹ Power Adapter and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
If the drive is connected to a hub, connect it to a built-in port on the computer.
If a firmware update is available for the drive, apply it.
Contact the drive manufacturer to see whether there's a firmware setting you can change.
If you installed vendor software for the drive, uninstall it.
If none of the above steps resolves the issue, try another drive.

Not able to create OUT file with "nidll_vxworks" in Matlab for use with the LabVIEW SIT 2010 and a cRio 9073, sh.exe error

I am trying to compile an OUT file for my Simulink model using "nidll_vxworks" and run it using the Simulation Interface Toolkit for a cRIO 9073 . I am able to compile the DLL file using "nidll" and succesfully run the simulation using my PC as the host.
I already downloaded the "gccdist" and "vxworks61gccdist" folders and copied them to "c:" When I build the model in Sumulink I get the following error at the end of the process (at the same time windows tells me that "sh.exe" has stopped working). If it matters I am running Windows 7 64bits, but using Matlab 2009b 32bits and LabView 2010 32 bits. ANY HELP WILL BE APPRECIATED. "QofV" is the name of my Simulink model and I changed to "XXX" parts of the file path.

Partitioning an External 320gb drive for use with Time Machine and...

I want to be able to use my Western Digital 320GB external drive for use with Time Machine and to use as extra storage space on both my Mac and when I boot into Windows Vista.
Is this possible?
I was playing around in Disk Utility and would I partition the part I want to use for Time Machine with the Mac OS Journaled, and whatever I want as space for windows, use a MS - DOS format?
Has anyone done this before?
Cheers-

Unless you are using 64 bit version of MSWindows (64 bit XP/Vista), it won't be able to handle a disk with GUID partition table (GPT). Disks with Apple Partition Map (APM) or GUID partition table are the only ones that Time Machine will work with (not MBR disks). Note also that the MBR/APM/GPT are at the DISK level and not the partition level, so don't mix the format with partitioning scheme. Time Machine disks are meant to live in the Mac universe (for now, anyway) and sharing with the MSWindows 32-bit universe is not possible.

USB external portable HD for use with FCE and MBP ???????

I've seen a 120 GB USB portable external Seagate HD for $117. Would this be usable as a scratch disk for use with my MBP 2.0 and final cut express HD 3.5. Are there problems with using USB externals? FW external hd's seem to be a good deal more expensive.
Thanks.
Maurice

I bought one recently very cheaply to use for general storage.
I found that FCE 3.0 worked perfectly and have been using it ever since instead of my FW HD.
HOWEVER, before you dash out and buy one take note that I have only been tinkering around and experimenting with comparatively short projects of no importance.
I strongly suspect that if I made a long and complicated film I might suffer - so pay the extra and get a FW HD !
Incidentally for normal storage purposes the USB2 HD takes over twice the time to move files back and forth. So even for non-FCE use the Firewire HD is twice as fast.
Ian.
