Cannot rewrite hard disk
HI, I cannot seem to rewrite my external hard disk. Under General info, there isn't a "locked" box which I could tick. The sharing & permissions states that I could only read.
What can I do to unlock it?
Thanks.
How is it formatted? OS X can read, but not write to an NTSF formatted drive.

M6-1105dx cannot detect hard disk
my machine is m6-1105dx with window 7. It cannot boot up with an error "boot device not found, please install an operating system on your hard disk." The error number is 3F0, and it reminds pressing F2 for system diagnostics.
In the diagnostic, memory test works fine, but hard disk check gives error "SMART Check: NOT INSTALLED; short DST: NOT INSTALLED".
I tried with two different hard disks and it gave same errors. Anyone knows what is going on?
This question was solved.
View Solution.Assuming the hard disks are actually showing good on another PC, then the SATA cable may be bad, the power connections may have failed, or the contoller is bad. I would start with verifing that those first several items - hard drive, SATA cable, power connections, ETC are good. If it is the controller, it is not easy to repair on a laptop. Probably need a new motherboard. I used something similar to THIS to verify the drive is good or not.

Computer cannot see hard disk -- Brain teaser
Okay, long story short, I use bootcamp 1.3 (I believe 2.1 is for Leopard only, as it is listed in the requirements of the Apple downloads website), to partition the drive and install Windows.
My first disk was the stock SeaGate 120 GB that came with my MacBook running OS X 10.4.9 (updated to 10.4.11 through Software Update) and Windows SP3. I ran into a problem where the disk could not be recognized, even after a Hardware Test proved "no troubles", though a System Profiler scan of the SATA drive showed "errors on scan" so it could not profile it. Took the MacBook to an Apple repair service, they found the Hard Disk corrupted and could not access it either through their own computers after it was taken out. So I bought another disk as a replacement...
500 GB Western Digital, installed it, and erased and installed OSX. Updated it to the later 10.4.11 with all security updates. Then again, BootCamp 1.3, installed Windows Home SP2. Installed Mac/Window drivers, and then started to update Windows to SP3, and things seemed okay but only for another 10 minutes while it was "downloading" the update during the installation process, then Windows bailed out. I booted into OSX, was running slower than usual, then jammed and rebooted, folder with a question mark. Couldn't find hard disk. Couldn't even erase and install as it did not give any options for a hard disk to install in. Same when booting into Windows disk, could not find a hard disk to format or install into. Hardware test same as last time: no troubles, can't scan SATA. I actually managed to take the disk and the receipt to the store, who couldn't get the disk accessed, and they gave me another as replacement on the basis that it was at fault.
Now, I erased and installed OS X 10.4.9, it's working great. Haven't downloaded any updates yet, nor have I downloaded BootCamp, for fear of running into the same situation a third time. Using it right now to type this out for any thoughts from interested parties...
Think it's the OS X updates, or the Windows SP3 download, or what? Any ideas would be greatly appreciated, I unfortunately need to access Windows this month for a portfolio submission, and all of my expensive programs had been bought for Windows until I got this MacBook in '07.When was the BootCamp beta set to expire?
Depending on the version and time-line, some early
BootCamp users had some issue with it and there
was some discussion. Maybe you should look into
this item separate of the OS X 10.4.x install & up-
date issue. BootCamp's created installer disc and
the need for it to partition the hard drive in order to
install Windows on its own drive space, add up to
a source of trouble; especially if BootCamp is the
cause behind the OS X problems.
If these are somehow connected, the BootCamp
issue may be better addressed in that specific
forum Discussion; or it already was discussed there.
Have you over-written the entire drive using Disk
Utility (zero it out) then reformat, and start afresh?
What format regime did you use? Sometimes, it is
the little things; & I wonder about Beta BootCamp.
And if there is some corruption or failed cable in
the computer that could be aiding & abetting.
Good luck & happy computing! -

Cannot locate hard disk during reinstallation
Hi. There was a question mark icon when I started my MacBook. So I tried to reinstall with a cd. Now during the installation, at the point where I am asked to 'select a destination', there is no hard disk appearing.
1. What does this mean?
2. Will I be able to retrieve my files?Hi tengkygan, and a warm welcome to the forums!
1. Almost always means the Hard Disk has died.
2. Maybe, tough to tell at this point, but you need another Drive to install to & boot from, then try using Data Rescue...
http://www.prosofteng.com/products/data_rescue.php
(Has a Free Demo to see if it could or not, but you'll need another drive to recover to).
Or professional Data Recovery Services.
You won't even get to keep your old drive, but see this...

Cannot Format Hard Disks for Re-installation
Hello, first post,
I have a computer that stopped working and showed the folder icon with a question mark when attempting to boot the machine. Since I was able to boot to internet recovery and things appeared normal aside from not being able to find the OS. I attempted to verify/repair the disk using Disk Utility. My disk was unable to format after multiple attempts. I took the HDD out of the machine and put it in a known working machine and was able to format it. After putting it back in the original machine, I found that it only detected 67GB of the 500GB HDD when the working machine detected all 500GB.
I bought a replacement HDD and I am not able to finish erasing/formatting the disk. On both disks, it never gets stuck in the middle of formatting in the same place. Sometimes it gets stuck unmounting the disk, sometimes while creating the new partition. I am using the GUID partition map. Any ideas about what could cause these issues? Could I have a different hardware problem that might be causing this issue? Any help would be greatly appreciated.If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing.

Cannot recover hard disk space when deleting and huge sparseimage
hi there,
System Version: Mac OS X 10.4.3 (8F46)
Kernel Version: Darwin 8.3.0
my problem is that I found the mac was running slow and I noticed the harddisks were getting full:
[veronique:/Users/e] e# df -H
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s3 60G 59G 729M 99% /
devfs 102K 102K 0B 100% /dev
fdesc 1.0K 1.0K 0B 100% /dev
<volfs> 524K 524K 0B 100% /.vol
/dev/disk1s2 60G 59G 725M 99% /Users/e

automount -fstab [250] 0B 0B 0B 100% /automount/Servers
automount -static [250] 0B 0B 0B 100% /automount/static
Im not sure why they became this full but.. I then looked for big files and found a sparseimage of 40GB. I can mount it and all so it s in good shape.
I needed to free up space and I delete a lot of music files, pictures, a virtual pc file of several gigs and so forth, but when I ran a new df -H things had nt changed.. So im guessing all the data, inclusive deleted data is in the sparseimage? is this so? I ve emptied the trash several times.
I ve now tried to turn filevault OFF but it asked me to free up 1.9Gb.. catch 22.. if I rid myself of files it wont see more freed up space...
is there something I can do? I could mount the sparseimage and browse it and delete files there or back up whatever I need and then get rid of it? should I re install?
any help needs to go to [email protected] i went into my settings but didnt find out how to change my email. thats not impressive i know
ericHere's what I had to resort to to forcibly reclaim missing free space on my FileVault-encrypted PowerBook G4.
After several days and more restart/shutdown trials than I can count, I could not for the life of me get my PowerBook to give me the "Reclaim free space" option that usually pops up. Not sure why. But, I was missing nearly 12GB of free space and kind of needed it.
I was able to force a space reclaim... but the process isn't exactly point-and-click.
•I mounted the PowerBook via Firewire target disk mode on my desktop and copied over my PB account's .sparseimage file to my desktop (didn't want to work on the original file in case I screwed it up).
•Used the terminal command "hdiutil compact" on the .sparseimage file (type "hdiutil compact " (with a trailing space) then before hitting return, drag the icon of the .sparseimage file on to the terminal. That'll insert the path of the file. Hit return.)
•Let it run. Took about 15 minutes or so. On a 27GB .sparseimage, the procedure recovered 12.5GB!
•Deleted the original .sparseimage from my PowerBook, emptied the trash, and copied over the newly compacted one. Rebooted the PB, and voila!
Do keep in mind though that you'll need at least as much free space as your Home folder occupies itself if you want to turn FileVault off.

HARD DISK DRIVER ISSUES WHILE INSTALLING WINDOWS 8
I am trying to install windows 8 on my PC, but it is asking for hard drive drivers. I have installed windows 8 before with no issues on the same PC with same configuration, but now I am facing these driver issues. Currently I am running Win7 as i cannot
reinstall Win8.
Config:
Gigabyte Motherboard 945G with Intel Core2duo8400 3ghz,
Intel(R) 82801G(ICH7) FAMILY CHIP SET,
4gb Ram, Nvidia graphic card, Seagate hard disk 160Gb.Hi,
I doubt that the hard drive is either a SATA drive or in a RAID setup, you might need to install RAID controller drivers or SATA driver during the installation.
I also suggest you refer to the following link and check if it can give some hints.

Hello,
Issue:
On a Virtual Machine with a secondary VHDX attached, I cannot manage (bring online, initialize, partition, format, or write to) the VHDX hard drive once it has "Enable Virtual Hard Disk Sharing (VHD Sharing)" enabled.
Questions:
Should I be able to manage (bring online, initialize, partition, format, and write to) a VHDX hard drive once it has VHD Sharing enabled? If I should be able to manage it, what am I missing?
Topography:
One SuperMicro Cluster In a Box (CIB) with 2012 R2 Data Center on each node. Microsoft Failover Cluster installed and working on each node. The Failover Cluster Servers on each host passes all cluster validation tests. Two Hyper-V 2012 R2 Data Center Virtual
Machine (VM) servers, one on each node. 1 common Cluster Shared Volume (CSV) and 1 Generation 2 Scale-Out File Server (SOFS) shared volume both Resilient File System (REFS) formatted. One 5 Gigabit (Gb) Virtual Hard Drive Type X (VHDX) file on the CSV and/or
SOFS. Integrity bit and read only turned off on VHDX file.
Each of the two Hyper-V VMs have one 127Gb VHDX Generation 2 primary hard drive and 1 VHDX secondary hard drive attached, both on SCSI Controller #1.
Background:
If I start VM1 without the VHD Sharing enabled on the secondary hard drive, I can bring the drive online, initialize, partition, format, and write to the drive.
If I enable VHD Sharing, I can no longer modify the drive in Disk Management in any way. With or without VM2 running.
Both VMs and the CSV and SOFS are on the same host cluster server, or not, no difference…
The VHDX is referenced either by the CSV name C:\ClusterStorage\Volume1\TEST1.VHDX
or a Shared Folder name
\\sharedfolder\folder\Test1.VHDX .
If I start VM1 with VHD Sharing disabled and I format the drive, then shut down and enable VHD Sharing, the drive is offline and requests initialization which fails with an "I/O device error", every other attempt to manage the drive fails with
the same "I/O device error", error.

Thanks again for any help,
RobertHi All,
I had to buy a Willy Wonka bar and spend a golden ticket to get an answer to this one.
We found that the default LogicalSectorSizeBytes of a VHDX is 512b. It needs to be 4kb.
The Host drive doesn't seem to matter CSV or SOFS. Below is a way to create a VHDX with the correct LogicalSectorSizeBytes.
In Power Shell, type --> New-VHD -Path C:\ClusterStorage\Volume4\Cluster2DataDisks\Cluster2Disk1.vhdx -SizeBytes 200Gb -PhysicalSectorSizeBytes 4kb -LogicalSectorSizeBytes 4kb
Attach the resulting file to your guest cluster servers and set the Enable Virtual Hard Disk Sharing option on both server. You should now be able to bring the drives on-line and initialize them. They will also add to the guest cluster pool.
Change the size, path and file name above to fit your Cluster Servers configuration.
Thank You
Sachin Kumar Support Engineer | Windows Server Setup Team | Microsoft Enterprise Platform for finding the answer to this one.
Hope this helps others.

ITunes cannot write to my lacie hard disk
I have an iMac G5 that I recently upgraded to 10.4.10. I've had a 160 firewire lacie hard disk for over a year, and all of my iTunes content is stored and called from that device.

I've tried manually copying the files over via the Finder, and that is yielding an error (error code -36).
any thoughts? I've also had iChat problems since introducing 10.4.10, wonder if that's part of the problem.I have an iMac G5 that I recently upgraded to

Error -36 is an i/o error. This means that you almost certainly have a hardware problem. This might be with the FireWire cable; replace the cable. It might be with a FireWire port on the disk; put the cable into a different port. It might be with the FireWire port on the Mac; try a different port. It might be with the FireWire controller on the Mac; try a different Mac. It might be with the FireWire controller on the disk; put the disk into a different enclosure.
Unfortunately, what it's most likely to be is with the disk itself. I hope you have a backup.

Cannot see my shared USB hard disk's connected on my Mac-mini on my Macbook
As you all can see, I'm a Mac user since 1989, i've don't like working on a windows-computer.
But i've got a problem since I'm using Mac os X 10.5. If i try to make a connection with my Macbook pro to my Mac-mini (my Mac-mini has two USB hard disks) i cannot select the USB hard disks. But my WIDOWS computer has no problem to approche these disks???? Can anyone help me????Hi WillemH777-NL and welcome to the discussion forums.
On the MacMini open system preferences-->sharing
then select 'File Sharing' from the Service column. Then under Shared Folders make sure your 2 usb drives are listed, if not click the + sign and add them.
then click the 'options' button
make sure Share files and folders using AFP is checked
make sure Share file and folders using SMB is checked
Then switch on the names of the users and the mac can use the smb service.
then click Done
Now see if you can access the mini's sharepoints. -
Help, I installed parallel and windows, and opened videos (on an external hard disk) with windows, and now cannot open them with Mac, and use i movies. How do I reverse this?
Paragraphs help the reader, just saying.
What are you actually trying to do? Why do you need "DVD size" folders if you're creatng an Archive on an external hard drive?
Also, I understand burning folders instead of individual photos or albums gives you more space on a DVD.
It makes no difference at all.
How can I keep the captions on my photos (not events) when I print or transfer to a new folder?
You can export while writing the metadata to the file in most cases.
Tne only way I know is to copy photos from the Windows to folders on my HD, then copy and paste photos or albums or events to HD, then create a new folder and fill it to the appropriate DVD size.
HD? Another HD? You use HD there in a way that makes no sense. What's the point of 'DVD size'?
I also thought I should download future photos to my Canon programming that comes with EOS cameras and edit and then decide which photos to save to iPhoto library and which to save only to my archival HD?
Does this have any relation to the previous questions? You know you can delete from iPhoto, right?
You're somewhat confused and you need to
1. Decide what exactly you want to do
2. Then go about it.
If I understand you correctly - and there's no guarantee that I do - the easiest thing is to bring all your Photos into iPhoto and do everything from there.
You can have an archive on an external disk, you can sort and select and edit with or via iPhoto

I have a 1TB WD external hard disk, which suddenly cannot be detected in my system. When i connect the hardisk to the macbook, the disk appears and immediately disconnects with the message "Disk not properly ejected". Any advice ?
verify on another Mac if the same
WD is having issues with mavericks as you can see on the WD forum, did you install any WD software (never do that) when you connected the drive for the first time?
possible issue is a dead SATA bridge card or the new WD firmware w/ Mavericks.

Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
