Can't Format Disks on Arch Install

So I burned the latest 8.19.2011 'netinst' ISO to disk. My system has two identical 1TB SATA drives (/dev/sda & /dev/sdb) & after the system loads, I try and format the 1st and 2nd disk using 'cfdisk' utility and I get the following error:
My Arch Install wrote:Wrote partition table, but re-read table failed. Run partprobe(8), kpartx(8), or reboot to update table.
Then when I re-open or launch (not sure what the correct term is here) 'cfdisk' utility again on the same drive, the partitions don't look correct. I thought my disks were bad so I used two completely different identical 1TB drives and they too have the same issue. What is causing this and does anyone know what I'm doing wrong?

Can't format disk in a terminal session

Hi,
I'm trying to reinstall my mac os x server software on my headless xserve. It has a PCI raid card in and I have created a 500gb logical raid 5 volume (megaraid -create auto). However when I boot the xserve from the setup disk and then use server assist on another mac on the network to install the system it does not see any volumes available to intall the software. I know I need to format the drive but every diskutil command I try just seems to hang the terminal session and nothing happens. Please could someone give me an idea as to the terminal commands I need to use to make the volume visable to server assist.
Thanks in advance for your help

Hi CKlitho,
   The UNIX command, diskutil, will do anything that the GUI app, Disk Utility, will so it doesn't matter whether you use the command line or not. If there is a device file for the drive, then it is attached, can be mounted and you can do anything you want with it. Otherwise, it might as well not even be connected to the computer. You may be able to tell if there's a device file with the "df" command. (no parentheses or arguments required)
   I'm guessing that there is no device file, since otherwise the disk would probably be visible to Disk Utility. If that's the case then the problem is probably that there's no driver for the PCI card on the setup disk. If that's so you will have to arrange to boot from something that contains the driver in order to do what you want.

Satellite L305D S5895: Win 7 can't find HDD or can't format HDD on clean install

I have a customer's Satellite L305D S5895 laptop. This was shipped to me by the customer who tried to install Windows XP Pro, Vista and none would install.
He said he tried all installation CDs he had and finally gave up on it and shipped it to me.
When I got it the partition were deleted so I tried to install Win 7 and when I do doing a custom install I get an error saying the hard drive can't be formatted on disk 0 or it will give an error that no hard drives were found.
I reset the bios to default and no matter what I do it won't format or find the harddrive. I was going to upgrade the bios but the only way I found to upgrade the bios is after windows is installed.
Anyone got any ideas on this laptop so I can get a system installed. I checked the bios and there is no settings for a sata drive, raid drive or IDE drive so it looks like this version can't be changed.
Thanks for anyone who can help.
Rick

The upgrade instructions do not help, I am not doing a upgrade but a clean install and the Toshiba Software Installer for Windows 7 doesn't look like it will work because it is an .exe file and with no operating system I don't see how it can run but I can't find instructions on how to use the installer
I've tried running tests on the drive to see if it is bad or going bad but after trying about 4 different programs and all having the same results I think the drive may be bad.
All diag programs I've tried boot the computer and show "STARTING PC DOS" and they all stop at that point which I guess is an indication the drive is bad because they can't seem to find it, not sure just guessing as to why all stop at this point.
I've tried SeaTools and Hitachi Drive Fitness Test and a few others only to have them all stop at "STARTING PC DOS"

Can't eject disk image after install on Mac, get error message: The disk "Thunderbird" couldn't be ejected because "Thunderbird" is using it.

this is an upgrade from previous to current version. seemed to have started around the time yosemite came out.

I don't have a background image. I called Apple and they had no idea what that error number meant. I deleted preferences for FCPX still didn't work, then delted all preferences and set up a new user. It now works. Apple has no idea what is going on.

Keep getting "Can't Locate Disk" error message when installing software

Hi!
I'm trying to install some software on my PowerBook G4 . . . every time I follow this routine:
1) I insert the installation disk of the software.
2) Classic 9 starts up - I then get the folder on the disk with then install icon.
3) I toggle through 3 or 4 screens, agreeing to licenses, etc. - then . . .
4) When I click on the "OK TO INSTALL" button an error message appears and stops my progress - it reads, "Can't locate disk" - duh! We've been working off this disk for 5 minutes - the disk shows up on the desktop - I can locate the disk - why can't my computer? Please help me if you are able - thanks!

Thanks Bob! My problem was that I was following advice from elsewhere on the internet that said I should burn a DVD in UDF format when in fact just burning it using disk utility in ISO made it work. Thank you so much!

How can I format an HD with System 10.4 and install Leopard Snow?

How can I format an HD with System 10.4 and install Leopard Snow?

You need to partion the hard drive using Disk Utility. On one partition install 10.4. On the other 10.6. As a note I trust you are doing this on a MBP and not a PPC Mac because 10.6 won't install.

Format External Drive Error can't unmount disk LaCie 1TB External Drive

Help!!

Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After Disk Utility loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

Can't format ssd... Disk Utility Hangs

Hi all!
Too long; didn't read: I need a way of formatting clean SSD for installing OS X, as the apple Disk Utility doesn't seem to be up to the task!?
A bit of background (UNRELEVANT for question, here to make thread useful to others when searching): A couple of days ago I upgraded my MacBook Pro mid 2010 from OS X 10.7 Lion to 10.9 Mavericks.
It's a standard 13" Macbook Pro mid 2010, cheap edition, except for the HDD to SSD upgrade (upgrade ordered while ordering computer, this it's an Apple SSD).
Suddenly yesterday my computer would not wake from sleep. I closed it by a long press on the power button, restarted it, it used a lot of time to show the Apple logo on white background along with the "working wheel" (around 10 or 15 minutes), then replaced the Apple logo with a "No Access"-logo.
While runnig a Disk Repair un Disk Utilities from a Lion Setup DVD fixed the startup issue in the first attempt, the the computer just froze when I logged in, and I choose to reinstall from scratch.
The SystemsRescueCD (small Linux with a lot of file-system support) proved very useful for making a backup of my data.
Attempts at formatting: The Apple Disk Utility (no matter if it's run from Lion DVD or Apple Internet Recovery) is extremely slow at formatting the SSD. Sometimes it will hang for 10 to 20 minutes, and it only completed the formatting once... kinda...
it took around 6 hours, but after trying to unmount the disk for 4 hours, I choose to kill the computer (and restart), as the partitioning step was complete. OS X could not be installed to the disk.
Since the Apple Disk Utility couldn't format the SSD, I tried formatting in GParted (using SystemsRescueCD) to HFS+ with Master Boot Record GPT (GUID Partitioning Table). It took around one second to complete.
When rebooting and starting the OS X installation, it did "see" the partition, but complained that the file system wasn't journaled. I used the Apple Disk Utility to enable journaling (it seemed to work!), but when I restarted the installation, it froze when it had to deal with the filesystem.
To check if the SSD was able to boot a operation system, I installed Linux Mint. Besides from the usual driver issues with Linux, it worked.
I really hope someone can help -- my Bs.C. thesis is due quite soon, and this computer crash couldn't happen at a worse time

Longtallsally28
I was thinking that same thing but it said it only applied to MacBook Airs.
Not so,...any and all SSD can fail.
#1) Why does the computer not recognize SSD partitions? (i.e. revert to Disk0s1)
A likely failed SSD
#2) Is there a possible component within the computer causing the continued failure? ( Is there a diagram showing all the components within the MBP?)
Yes, the SSD controller on the SSD module
#3) What do I have to do to make this computer work?

Can't format internal disk

Hi
I have a Mac Mini from late 2012
I have installed a SSD and kept the old disk for data-storage (1 TB).
Both disk was originally formatted to "Mac OS - extended (Journaled)"
I installed the OS X successfully on the SSD - and everything is working fine on that.
BUT I can't access my data disk. I can see the disk - but I'm not allowed to edit or add anything to the disk.
I have tried a lot of stuff:
Taking the disk out of the computer and reformatting it completly with my Macbook Pro... with out any problems can access the disk and edit on it.
BUT as soon as I add it into the Mac Mini and boot up - the OSX sees the disk but won't let me edit/write to the disk.
Gives error -50
I also tried writing to it from terminal as sudo - no luck.
I tried to reformat it in recovery mode ( and tried booting from USB stick)... BUT the system keeps saying that it can't format the data disk because it can't be unmounted...!
MY EXTRA DISK CAN'T BE UNMOUNTED.... ***!? (also tried unmounting from terminal... same errors)
It has no problems deleting the SSD disk....
-I'm using the well-known; OWC Data Doubler to connect my data disk to the secondary position in the Mac Mini
Please help... because I have no idea how to fix this. (Both disk can be wiped as needed - I just want a system with SSD and normal extra disk)...

Thanks for replying.
My SSD is: Corsair SSD Force Series 3, 240GB 2.5"
I didn't know that you could change any firmware on the SSD it self... and Corsairs homepage do note write anything about it.
I tried to switch the two disk around.
Now it only sees the 1TB disk (apple original) and I'm not able to see the SSD (not even in the terminal)
So right now SSD is in the lower...
hmmm... if I had a problem with the cable or controller - would it throw this kind of error?
Next step; I'll try to install the OSX on the 1TB disk - just to see if the SSD will be reconized later.
But still looking for help.

You will need to boot from another source: a bootable clone, your old internal in an external enclosure, or your install disk.

SL install error: "Can't use disk to start up"

I've spent some time searching the forums but haven't come across a solution that works yet. I currently have 10.5.8 and have a family pack for SL. I've installed it on a 24" iMac just fine and a 17" MBP. I'm now trying to install on a 15" late-2008 MBP and am getting the error that says snow leopard can't install to my Macintosh HD because that disk can't be used to start the computer. That's funny because it seems to be able to start just fine and I'm not experiencing any nagging issues with my Leopard install. I'll mention that I use Boot Camp and have a Win7 partition on the same drive.
Per one of the other posts I've tried the following:
1. Zap the Pram- No change
2. Resize Mac partition- Disk Utility won't let me change the Mac partition for some reason. It says that it needs to be HFS+ Journaled, which it is. That's a bit confusing.
3. Repair Permissions- I've repaired permissions on the Mac HD, but no change. I've heard that I need to repair permissions at the root drive level in Disk Utility, but when I click on the "whole drive" icon, Repair Permission is grayed out.
For insurance sake, I've cloned both my BootCamp partition and my Mac Partition ( I also have an up-to-date TM backup and everything's backed up to Mozy as well). So I could format the drive and try a fresh install of SL. Then I would have the choice of using Migration Assistant or something of the like to pull in apps and Docs from TM right? I don't mind doing a fresh install but it would certainly save time to simply upgrade.
Are there any performance issues that I might encounter by using Migration Assistant to pull the info from my TM backup?
Any way to address the issue so I can do a simple upgrade?
Thx.
Jonathan

When I look I see GPT/GUID 200MB partition, then one 128MB, followed by HFS+, and a second 128MB at the end.
Maybe things have changed and the docs on rEFIt doesn't acknowledge Apple's use of UEFI 2.x that began in 2008.
Quote from their web site:
*Myth: Mac OS X requires GPT*
+This is mostly a myth. Mac OS X boots and runs just fine from disks using MBR partitioning, or even APM (Apple Partition Map, used on PowerPC Macs).+
+However, the Mac OS X Installer will refuse to put a fresh copy of Mac OS X on a disk that’s not using GPT. You can work around this using cloning tools like SuperDuper! or Carbon Copy Cloner. Install Mac OS X on a GPT-partitioned disk first, then clone it onto the disk of your choice.+
+Apple’s firmware updates are another issue. The exact requirements are not known at this time, but they are known to not work if you don’t have GPT and you don’t have a EFI System Partition.+
+Myth: Mac OS X requires a hidden EFI System Partition+
+Every GPT-formatted disk is supposed to have an EFI System Partition, and Apple’s tools create one at the beginning of the disk. However, Mac OS X doesn’t actually use it; the EFI System Partition is completely empty on a standard Intel Mac. Apple has added a HFS+ file system driver to its firmware, and the firmware boots Mac OS X directly from the partition it is installed on.+
+Also see above; Mac OS X can boot from a MBR-only disk with no trace of an EFI System Partition.+
+There is still some uncertainty about firmware updates, though. So far no one has investigated how they work in detail, and some people believe they require the EFI System Partition to be present.+
+Myth: EFI requires GPT+
+The GPT specification is part of the EFI specification. However, all parts and features of EFI are just as well-defined for MBR-partitioned disks.+

I've never used rEFIt but obviously seen it discussed and used a number of times.

Satellite U400-112: can't format local disk (damaged MFT?)

Hello!
I got rather serious problem with my HDD.
HDD 250Gb
C: 116Gb - NTFS - Windows XP (Vista initially)
D: 1,5Gb - NTFS - (Vista Recover?..)
E: 117Gb - RAW (was NTFS before crash)
MFT of local drive E: was damage because of the virus attack (I hope not because of my foolishness!). It was NTFS, now it is RAW. I recovered all necessary data from lost partition with program ZAR, but all my attempts to recover or just format E: remained unsuccessful.
No bad sectors found on HDD. Windows standard tool for formatting disks fails: "It is impossible to finish formatting of E:".
Before this problem with drive E:, I got several difficulties with HDD. I have never re-divided disks, as from the very beginning Partition Magic identified it incorrectly. I tried Partition Magic 7 and 8.
Link: [ Error screensaver|http://cs1498.vkontakte.ru/u169802/154397/x_3a82b4fb.jpg]
The problem is that special programs (I tried "Find and Mount") also could not identify partitions to correct defected MFT. I thought that low level format may help me, but i heard, what use of any applications from other producers can probably destroy my HDD. Are there any special applications from Toshiba developed for such cases? Or you may advice me something else?
Thanks for your help!
P.S. These applications didn't helped me:
Find and Mount (doesn't find HDD)
Acronis Recovery Expert (doesn't find HDD)
OnTrack EasyRecovery Professional (didn't fix error, but helped with data recovering)
HDD Regenerator

So have you recovered all your important data?
I would just run Recovery to restore the HDD back to its factory state. If Recovery fails, you can try removing the partitions using FDISK from an MSDOS boot disk. Free bootdisks can be found at www.bootdisk.com
FDISK can also repair a Master Boot Record by running this command: FDISK /MBR
But its not 100% reliable, it could cause more harm than good.

Hello!
Did you boot to the Internet Recovery Partition?
Here’s how:
1/ Make sure your computer is completely shut down.
2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [alt] + [cmd] + [r] Keep these keys on your keyboard pressed until you see a spinning globe with the text “starting Internet Recovery” You might have to connect to your Wi-Fi network before you can continue here.
After a few minutes, you’ll be presented with a Utilities screen. This is the Internet Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
3/ Choose Disk Utility and click [continue]
