Hard disk size after clearing partition

hello. i need help undoing what i did to my macbook 13". i recently purchase the time capsule and it worked fine for about a month until this week that it took a long time getting ready for back up and then it would stop without backing up. the error message stated "there may have been a problem with the network connection"
I then attempted to partition the hard disk by using disk utility. it did not help time capsule so i attempted to undo the partition. now i only have the main HD but when i go to see the size of the Hard Drive, it says 74.24 GB capacity (out of 160 GB), 51 GB available, 23.24 GB used.
How do i get back the rest of my hard drive? Thank you in advanced.

Open the Disk Utility, find the list of partitions, drag the divider at the bottom of the main partition as far down as it will go, and click Apply.

Does Labview RT 8.5 impose a limit on FAT32 partition / hard disk size?

We will be using a PXI RT system (spec below) to collect, analyse and store a
large amount of data (~30 to 40GB per experiment).
We don't want to keep the Windows host PXI attached
and so the RT PXI must be able to store all the data from an
experiment.
It would be desirable to keep data from all
experiments on the H/D, so a capacity of ~300GB would be useful.
Q: Is there a limit on the hard disk size imposed by the Labview RT 8.5 Operating System and if so what is
it?
An older
post (~2005) suggests that the partitioning tool limited FAT32 partitions to 32GB.
Thus the question I'm asking that if I created a large FAT32 partition with
a third party tool could I install and run Labview RT
8.5?
Q: Is there any other way of connecting a
large capacity H/D to the RT System? For example using H/D partitions, slave H/D. Other
ideas?
Thanks,

> The size limitation has nothing to do with
the LabVIEW RT OS. FAT32 limits you to 32GB. This cannot be changed since it's a
limitation of the file system format.
Thanks for
reply.
I have, however, gained the impression from a
number of web sites that there isn't a 32GB partition limit on FAT32 -- see [**]
below -- but the limit is with the
partitioning tool. It looks like the
partitioning tool that comes with RT has a 32GB limit (Is that correct?). Hence
my question if you were able to create a large FAT32 partition could you install
and run RT?
Regards,
Michael
[**] The following was copied from http://en.wikipedia.org/wiki/File_Allocation_Table#FAT32
Windows 2000 and Windows XP can read and write to
FAT32 file systems of any size, but the format program included in Windows 2000
and higher can only create FAT32 file systems of 32 GiB or less. ... This
limitation can be bypassed by using third-party formatting
utilities.

DV9000 Maximum Hard Disk Size Supported?

I'm searching for a used HP Pavilion DV9000. I need to know the maximum hard disk size the DV9000 series laptops support. To be clear, could I put a 750G or 1TB disk in each bay?
HP's web site isn't helpful. It gives only the "official" numbers at time of release which state it supports up to 240G, 120 in each bay. Those kinds of numbers are almost never an accurate statement of the limitation as I have seen similar "official" numbers for other HP laptops (supposedly limited to 120G or 250G or whatever) that have no problem supporting 640G in the real world.
The size of hard disk a computer supports is usually a function of the main board's chipset and I don't know how to determine the exact chipset or find the chipset's hard disk support capability. Again, HP's web site isn't helpful here either. They may list it has an nVidia chipset; but, they don't mention which nVidia chipset.
To be clear, I don't own a DV9000 yet and I need to know how to find this information maybe with the exact model number. The model series may be DV9000; but, there are dozens of more exacting model numbers on the bottoms of the DV9000 series computers (example: DV9025ea). I don't want to purchase a DV9000 and then find that its limitation really is 120G per bay.

Hard drive size is a limitation of the Bios, not the chipset, this was overcome with the implementation of Large Block Addressing 48bit in modern bios's in 2003
Hp does not state which bios's on older laptops support this or not.
Looking at the production dates of the 9000 series, I would be willing to bet it supports any size hard drive (48bit LBA), since 48bit LBA was introduced in 2003
http://en.wikipedia.org/wiki/Logical_block_addressing
That being said, there could be brand compatibility issues, so be sure to buy the hard drives from a source that has a friendly return policy.
Maybe some one can post that has actually installed a large hard drive in a 9000 series.

Unknown hard disk devices after LVM blunder

Hi all,
I have a rather weird hard disk partitioning setup because I always find myself needing to adjust my partitions from time to time. So I decided to create many logical partitions and put my personal data on an LVM partition that spans over multiple logical partitions... so that I could resize easily and create space for other stuff as required.
The problem - I created a FAT32 file system on one of the partitions (/dev/sda16) that wasn't part of the LVM at the time (no resizing required). After doing this, I now have 2 disk devices (/dev/dm-0 and /dev/dm-1) that weren't / shouldn't be there. Also, the partitions that are part of the LVM setup are detected as FAT32 partitions by fdisk. The non-LVM changes I made with fdisk and parted while for LVM management I use Kvpm. I grew the LVM Volume group and Logical volumes to fill the disk, including the FAT32 partition I created earlier.
Here is some output:

HP Pavilion g4 2131tx, Hard Disk Error after Blue Screen of Death

Hello! I do not know what section shoud i post this problem, I apologize for it.
So my laptop is freezing for a days after BSOD. When I leave my laptop overnight for downloading torrents, I always receive the message "Windows has recovered from unexpected shutdown." when i woke up.
I already disabled all non-microsoft services, start up items and yet the desktop is still freezing right after the welcome screen but the welcome screen does not load too long.
The desktop freeze for more than a minute then it will go back to normal again until my laptop went to BSOD
and received this error from UEFI "Hard Disk Error." after restarting.
I ran the Hardware Diagnostic Test and I got the result:
Failure ID: RW042K-6MT6RP-MFPX1F-61BK03
Product ID: 65H69PA#UUF
I tried cleaning up registry and defragmenting disk and still no luck.
* My laptop is HP Pavilion g4 2131tx and still under warranty until June 2014.
* I am using Windows 7 Ultimate 64bit Service Pack 1
* My RAM is 4gb with a processor of Intel Core i7
* My AV is microsoft security essentials
* I am using Advanced SystemCare for cleaning up registry and defragmenting.
I was wondering if I could change my hard disk while it's still under warranty.
Thanks for your help!

Hard disk problems after full upgrade [SOLVED]

After a full upgrage (pacman -Suy) last monday, My system denied to boot:D:D:D:D:D.
So to fix it I have to go to /boot/grub/menu.list and change from hda3 to sda3. Everything seems to be Ok but when the system is booting and scan the the hard disk to check bad, It drops me to the shell with the error that there is something wrong with my hard disk and it suggest me to set the superblock to 8139.
So to fix it I boot my PC from Arch live CD, use the following command:
#fsck.ext3 -c -f /dev/sda3
#fsck.ext3 -b 8139
Everything seems to be Ok, there is no bad in my hard disk.
When I boot my system again, I got the same error again, I came back to live CD, check the hard disk, set the superblock as It told me and again, I got the error when I boot from the hard disk.
This is the second PC with the same error.
Three months ago, I upgraded my Server and got exactly the same problem. Because this is the server, I need it run ASAP, so I modified the rc.sysinit script so that the system will not check my hard disk when It boots. :P:P. And my Server can run without any problems since then.
I don't have time much to spend on this error and my PC is in the Lab now so I can't provide the detail of the error until next Monday. Sorry for that.
Any idea how to fix this error?
Cheers.

:D:D I am a kind of lazy guy so when I did pacman -Suy, I just leave it running without reading information on the terminal.

Yes, you are right. I changed from hda to sda in /boot/grub/menu.lst but I forgot to do the same in /etc/fstab files. On Monday I will check again if it is set correctly or not
:D:D. I have just taken a quick look into the fstab file in my Server, The One with the same problem three months ago, and the fstab file is set correctly with sda partitions. I don't want to touch this server again or my services will be down. So this seems not the correct solution, but anyway, I will take a look at it next week.
Thanks for your replies.

Hard disk problem after installing Solaris 10 u5 on a Sun Ultra 24

Hi.
After receiving a new Sun Ultra 24, shipped with Solaris 10 u4, the first thing I did was installing Solaris 10 u5. X wouldn't start but that was not a big problem and installed it in text mode. Installation went fine but, when the system starts, a single beep is heard and after some seconds some warning message appear on the console, before the "Hostname: ..." message, informing that some read operation on my hard disk had timed out and were aborted. The system then starts up normally. The only other anomaly is that the diagnostic partition in unbootable.
I ran the hard disk tests from the tools and drivers CDs and all of the tests were passed. Solaris 10 u4 was working normally so I'm wondering if this may be a bug.
Thanks for your help,
Enrico.

Thanks anyway, I discovered what the problem was: a bug in Solaris 10 u5:

Missing hard disk space after sims 3 force quit

Hi, I failed to notice I had to update to the latest version of Leopard to install the game with the result that the installer got stuck repeatedly half way through and I could only force quit the installer.
The downside to this is that I did this twice and now I'm missing around 7 gigs of hard disk space....anyone know where I can find the files to delete or how I can regain that space?

DiskWarrior, as suggests nerowolfe, won't hurt for sure. It will repair damages done to files and the directory.
Maybe you could spot where the problem files are with this freeware, Disk Inventory X. You probably could identify files that are related to the game that are left on the hard drive. Did you do a Spotlight search to see if there any left?
And I'm also wondering if it wouldn't help to clean out all the caches in case there are temp files stuck in there? Download MainMenu and use it to clean out all the caches like so:
Uploaded with plasq's Skitch!
For the system cache clean up, choose +Deep Clean+. You will need to restart after the caches have been cleared.
Report back to let us know how it goes. Good luck!

No Hard Disk Detected after Erasing Free Space

Hi ,
First I will explain the problem, I will be grateful for your help to solve it as immediately as possible. Thanks in advance !
I have a MacBook Black since 2007, with system specification, 160 GB Hard Disk, 1GB RAM, 2.16 GHz Intel Processor. I had a OS X 10.4.11 Tiger version. I need to upgrade it to 10.6 Snow Leopard. I bought OS X 10.6 DVD Snow Leopard version from Apple Store.
Last night, I save my all the data on external HDD, and tried to install 10.6, and it is installed over 10.4.11 with everything on the internal 160 Hard Disk. I did not want like that. I again started the installation process, I went to Disk Utility, I did some thing with partition, i.e. I created again 160 GB partition. Then I wanted to format, Then I saw some Erase Free Space and only Erase also, I click on Erase only, it is finished in seconds. but I was not satisfied. I saw button Erase Free Space then I click there, then , it takes about 90 minutes, and at the end, I saw a failure message that it could not create the temporary file or something like that I forgot what was written, however, it was a failure message ( it is failed to create etc ) .. ,
Then I saw, that there was nothing in the disk utility tool except the installing 10.6 Snow Leopard DVD. I was shocked, what happened.
Does some body could help me in this regard. How can I get the internal HDD with installation DVD ? What should I do after to erase everthing from my internal HDD, I mean , there should be nothing on it ..,
A big THANKS to you to solve this problem.

Satellite L670 - Hard Disk Dead after 8 months only

Hi,
this morning I had to retunr my laptop due to bad hard disk problem. After 8 months, it's dead already.
The positive points are: I am still under warranty and second the toshiba software hilighted me on time, allowing me to back up my data before the crash. Tks Toshiba for this tool, very usefull.
The question is, how can a hard disk die that quick after just fews months ?
Bad luck or bad use ? I am wondering.
I wish to have a feedback from those who owns same model, L670 (windows 7), to understand if this problem is commun or if I was unluckily concerned.
Also, if there are possible solutions to avoid HD stress in the daily use ? Like for example, reduce writing on it (back up of blu-ray using AnyDvD HD ON hd, then cut&paste to external HD), or to not connect too often external hard disk to avoid electricity surcharge if any ?
In future, will I have to perform chkdsk more often ? Defrag ? If yes, at which frequency ?
This is my 3rd laptop dying, Sony VAIO = mothercard dead after 1.2 years, Fujitsu Amilo xi = explosed after 3 years, and now Toshiba HD after 8 months.
From 900EUR up to 1600EUR, I do not see a significative resistance of one of those models, Sony was the badest ever in terms of video card longevity and compatibility (games unplayable after 2 months, no driver update), keyboard "painting" was a mess with deterioration after fews months compared to Fujitsu and Toshiba (no pb). Toshiba L670 more recent, was the best in terms of game compatibility.
What to do ? Stop buying laptop or use it only fews hours a day with a PC on top ?
For time beeing I can't afford to have a PC + a laptop as I am unemployed, surviving with 10EUR/day,
time to find a job again.
Despite this situation, I managed to buy new Zelman notebook cooler for my Toshiba at around 40/50EUR, but, it didn't help apparently.
Tks for feedback about L670 duration life, and particulary HD problem + best use to protect it.
Guillaume

You're not the only one.
I bought an L670 in September last year. It was strictly for home use as replacement for a desktop PC, so it was never moved.
Just after a few weeks things started to go wrong: boot fails, programs crashing, Windows 7 crashing...
It's almost 7 months now since purchase and I'm writing this message on the very same notebook with 'Hard Disk Sentinel' running in the background, reporting more bad sectors every day. It tells me that hard disk health is now down to only 9% and that it has an estimated 14 days to live.
Since the notebook is technically still running fine, I don't think I can have the HDD replaced under warranty or am I wrong? Does the HDD have to cease working alltogether before I can have it replaced under warranty?

Seagate 1TB hard disk replacement after 3 years

Hi -
In mid 2010 I purchased a 2009 model 21.5" iMac with AppleCare for 3 years.
During that time, in 2012, there was a problem with the screen connectors, and the screen was replaced at Apple's authorized service lab in Israel, where I had purchased the device.
Recently, the hard disk failed. In the Disk Utility app the hard disk appears in red, the status is noted as "failing", and the system freezes a minute or two after booting.
I then discovered that there he had been a recall for this specific hard disk (Seagate 1TB), but I had not been notified about this recall. Moreover, despite the fact that the iMac had been in an Apple authorized service lab in 2012, they had not notified me about the recall or offered to replace the hard drive.
I promptly took the iMac to the lab, and was told that the recall program ended 3 years after the initial purchase, i.e. 1 year ago, and they could not replace the hard drive under this program.
It seems to me that if there is a known problem with this hard drive, and it actually failed, then Apple should bear the responsibility for fixing it. And certainly when the device was actually in their care during the recall period.
What can I do about this?

I had a different experience. I purchased a mid-2010 27" iMac in February 2011 from Amazon. I also purchased AppleCare, but never had to use it. I got both an email and a letter in October 2012 stating my iMac contained an affected hard drive and that I should have it replaced at no charge until the longer of my AppleCare warranty (which expired February 2014) or April 2013. It wasn't convenient at the time to have it repaired and it wasn't giving me any problems, so I dismissed the issue. In November 2014, I chatted online with Apple and explained the circumstances. They didn't hesitate to give me a code number to bring along with my iMac to the closest Apple service center to have the hard drive replaced at no cost - even though my AppleCare ended 9 months prior. The original hard drive still worked, but I felt more comfortable having it replaced as a precaution in case I decided to keep the iMac as a second computer or gift it to someone I cared about.

MacBook Pro Hard Disk Crashed after Frozen Screen

Hi
Very unpleasant experience with my first MacBook. My MacBook Pro Book 13'' (late 2010 model) screen froze on start up. Realised that the battery was low and plugged the power adapter in, and let the frozen screen continue hoping for it to start in a while, only to realise that the entire laptop heated up significantly. I switchd the laptop off and let it simply recharge.
No luck on restarting after laptop was fully charged despite several attempts and following all instructions on Apple website, including SMC reset. I took the laptop down to the store and the Genius Bar team informed me that the hard disk had corrupted and they could not retrieve any data.
Wondering if this is a common problem, as I have never had a hard disk failure before and specially surprising as it is relatively new laptop (<1 year) old ? Seems like a technical fault with the laptop prima facie. Some data was not backed up recently, and now I need to look for a recovery specialist, with costs to bear despite Apple Care.
Any suggestions on recovery specialists in London who do not charge a fortune ?
Thank a Lot !

Unable to change permissions on Hard Disk Drives after rolling back OSX Lion to Snow Leopard

Are you able to help me?
I had several problems with permissions and a series of other serious issues after upgrading to Lion, so I did a clean re-install of Snow Leopard 6.4 (from disk), upgraded to 6.8 and still had permissions problems which I have made worse by doing what I thought made sense - giving my administration user access to all hard disks and time machine back-ups. I emphasise "hard disks" because I have an iMac 27" i7 and 250GB Flash Drive provided by Apple where I keep OSX and aplication files. Thus the Flash Drive (FD) becomes the boot disk, not the Hard Drive.
Changing preferences on the Apple HD (not FD) and the Time Machine Backup HD to my user name (with administration privaleges) has had the reverse effect of not giving me access to anything other than my OSX system volume on my 250GB Flash drive! I can only see my files on the hard drives with the root user (which I have used for the first time ever to get that access). But using the root user does NOT allow me to change permissions of either my Time Machine backup disk or the Hard drive on my iMac ! Why oh why??
Googling for solutions suggested using iRepair to change permissions but that gives me a "boing" when I try with no effect - at least a "boing" is more feedback that the Apple Finder's response to my attempt to alter permissions in the "info" window!
Oh! and of course I have unsuccessfuly tried the Disk Utility as well, which does come back with errors - that appear to be "safe to ignore" from Apple Support's website!
I originally posted a slightly different message to this one to https://discussions.apple.com/message/16955471#16955471 because it appeared to have similar issues. It appears as if my problem is unfortunately quite unique!

So the background to this situation:
1. The user had OS 10.6.8 installed on one volume, while his actual users home folders stored on a second volume, this is fine but can sometimes cause issues during/post upgrade to 10.7
2. The user upgraded to 10.7 and while his home folders were still being accessed, he no longer had permission to change or modify them.
3. The user downgraded to 10.6.4 again which broke the link for his users completely.
4. In an attempt to change the permissions for his information he had the (common) mistake of changing the permissions of his root level of his drive, this did several things, in addition to negatively effecting his OS, it also locked the drive mount points in his (hidden) /Volumes/ folder.
5. the steps taken to help rectify this issue:
A. Open Terminal.
B. TYPE:
chmod -N /
chmod 1775 /
chown root:admin /
C. Reboot computer
D. Open Disk Utility.
E. Repair permissions on the boot volume.
F. Also the following commands were run on her second drive to allow him access to his stuff again:
sudo chflags -R nouchg /path to drive/
chmod -R 775 /path to drive/
chmod -RN /path to drive/
chown -R username:staff /path to drive/
Once the permissions repair is complete the Users can be readded to the System Preferences>Accounts pane and the paths to home directories located in his second drive using the "Advanced Options..." section, but due to the time the permissions repair was going to take this step will be posted tomorrow.
Also each user will require Terminal commands to make the permissions unique for each user: (this must be done PRIOR to the users being added in System Preferences>Accounts.
chmod -N /
chmod 1775 /
chown root:admin /
sudo chflags -R nouchg /path to home folder/
sudo chmod -R 775 /path to home folder/
sudo chmod -RN /path to home folder/
sudo chown -R username:staff /path to home folder/

Hard disk failure after just six days of purchase

I purchased a dv6-3093ca from Costco just six days ago, and the laptop completely froze up on me. I had to force shut down by holding down the power key. Afterwards the laptop was never able to restart Windows again (freezes at the welcome screen, and the system repair does nothing). I did a system diagnostics test and it passed every test except hard disk, which it failed.
Does anyone know how I can fish my files out of this? I didn't even have time to backup yet, because I figured a computer should at least survive for a couple of weeks before needing a backup...
This is completely unacceptable, because not only is the laptop top tier in terms of specs, it's actually one of the most expensive Pavilions as well. A brand new $1k computer broke down in just six days? I was merely running Firefox + MS Word + MSN at the time. Is there any fix for this (in case something like chkdsk works)? If not I guess I'll have to return it...

Come to think of it I'm not that surprised this happened now. I own three HP laptops (relatives bought the other two). One laptop basically could not be used for a long time with Vista, kept freezing for no reason, found it later it was another hardware problem. The more recent one's hard drive broke in just six days due to overheating, thanks to some idiot's design of cramming an i7 + 6GB RAM into a poorly designed system. The moronic "tech support"'s answer was "we will provide an exchange for you, after we send you a cardboard box, you send us the laptop, we fool around with it, then give you another hard drive when we feel like it, and by "when we feel like it", we mean either 2 weeks or 2 months". Yes it takes a lot of tech knowledge to come up with that kind of solution, and it took him an entire half an hour to type that into the computer as well. Waiting two weeks for an exchange that might break again? Lol like any person with a normal mind would do that. Returned it for a full refund right now and never touching another crappy HP product again. You fail at creating laptops HP, and what's even worse is that you fail at customer service as well.

Unusual hard disk activity after "Erase free space"

I have two partitions on my hard disk - a small partition for the system software and a big partition for everything else. A few days ago, I backed up a few files from my big partition and then used Disk Utility "Erase free space". Since then, my hard disk is behaving oddly. I can hear it, as if it continuously reading and writting data. At first, I thought it was an auto-update in progress or some sort of automatic system maintenance. But the odd behavior never stopped. I scanned my files with an anti-virus software - nothing wrong. I scanned my files with Disk Utility - nothing wrong. I used Onyx to check the system - nothing wrong. I even erased and reinstalled the system software - no changes! So what could possibly force my hard disk to behave like that? Is something messed up because of "Erase free space"?

You could run fs_usage
To view file activity for all processes with the fs_usage tool, you would enter the following at the Terminal prompt.
sudo fs_usage
If you wanted to limit the display to files accessed by a particular process, you could redirect the output through the grep tool. For example, to display file behavior for the TextEdit application, you would enter the following at the Terminal prompt:
% sudo fs_usage | grep TextEdit
Once your application finishes launching, stop fs_usage by typing Control-C in your Terminal window.
Look for all writes. Might be mdworker (Spotlight)
Try reindexing Spotlight by dragging the HD icon into the Privacy window. Leave it there for a minute and remove it using the minus button.
