Need help recovering an encrpyted partition

Hello linuXians,
I have a serious problem accessing my encrypted 2TB harddisk. I connected it in a icydock-case externally via USB.
When i add it everything is still fine:
usb 1-5: USB disconnect, address 5
usb 1-5: new high speed USB device using ehci_hcd and address 6
scsi9 : usb-storage 1-5:1.0
scsi 9:0:0:0: Direct-Access WDC WD20 EARS-00S8B1 PQ: 0 ANSI: 2
sd 9:0:0:0: Attached scsi generic sg5 type 0
sd 9:0:0:0: [sdf] 3907029168 512-byte logical blocks: (2.00 TB/1.81 TiB)
sd 9:0:0:0: [sdf] Write Protect is off

sdf: sdf1
sd 9:0:0:0: [sdf] Assuming drive cache: write through
sd 9:0:0:0: [sdf] Attached SCSI disk
Now i try to decrypt it as usual:
[root@silverdragon stony]# cryptsetup luksOpen /dev/sdf1 test
Geben Sie den Passsatz für /dev/sdf1 ein:
device-mapper: remove ioctl failed: Das Gerät oder die Ressource ist belegt
Schlüsselfach 0 entsperrt.
Apparently it succeeded in unlocking the keyslot 0 BUT the disk has problems:
Buffer I/O error on device dm-2, logical block 0
sd 9:0:0:0: [sdf] Unhandled sense code
sd 9:0:0:0: [sdf] Result: hostbyte=0x00 driverbyte=0x08

end_request: I/O error, dev sdf, sector 6088
Buffer I/O error on device dm-2, logical block 0
Now I don't know exactly how to procede or what exactly could be broken.
I assume its the superblock that i have to repair. I dont think its the luksheader or something similar.
Or do you guys think that the drive itself is broken?
Sadly the drive does not report ready so that I cant even run fsck over it to have a look at the filesystem.
What i find curious is that the drive only begins to report errors when i try to decrypt the data.
smart does not report anything unusual:

Does anyone have any suggestion how i can get the drive to be mounted at least once to recover the data?

Just a quick update: I was able to start testdisk on that devicemapper.
Lets see what it brings up....

*** Need help recovering music on iPod/iTunes ***

* Need help recovering music on iPod/iTunes *
I bought my iPod 30G when it first came out back in the day. With the protective case it looks like a Walkman, if you know what that is. The new ones are half the thickness of my old skool one. lol!
Anyway, years ago I accidently uploaded a virus in both my PC and laptop. Yeah, real *******. Well, the person who restored my computers couldn't save my music. I still have the iPod but my library on iTunes is gone. If I try to update my iPod in either computer it will erase every song I have on it and only upload the songs/album I'm trying to add. I'm told that this is something Apple did to prevent file sharing, blah, blah, blah...
Does anyone know a way around it? I keep buying CDs just not able to load them into my iPod thru iTunes.

Hello yourantihero,
And welcome to Apple Discussions!
There are several ways you can pull the music off your iPod and onto iTunes. The first link below provides step-by-step instructions for the direct method if you have a PC as well as a few third party applications (for both the Mac and PC) if you choose to go that route instead. You can also do a simple Google search for "copy music from iPod to computer" and you should receive a number of sites that can help you out.
Just make sure that when you have your iPod plugged into your computer, that you don't hit "Erase and Sync" before completing the task of copying your music over.
Also, if you have any purchased music, you will probably have to re-authorize your computer by heading to the Store drop down menu and choosing "Authorize computer."

Replaced hard drive in compaq presario cq62, need help recovering it with out disks

Recently replaced the hard drive in my notebook due to failure of original. Need help recovering it without disks

If you are wanting to install the original copy of Windows it came with, you will need a set of recovery disks.
Otherwise, you can purchase a copy of Windows to install and download the appropriate drivers from http://goo.gl/hOm3. Just make sure the copy of Windows that is installed is at least the same family of Windows to ensure that drivers are available.
What is the exact model of the notebook and product number?

Need Help Recovering Hard Drive Space on Disk Utility

I recently wanted to resize my Boot Camp hard drive partition as I did not need it to be 194 gb. In the process I screwed something up and now that space that was once my Boot Camp Partition is now "free space." My Mac Partition still says that I have 305 gb left and I am unsure how to expand this partition to get back that "grey" space. I've tried using Boot Camp Assistant, starting with Command+R after the "chime," and restoring my OSX (not completely however).
I need help in getting back this missing space. It seems that I have looked everywhere and although people seem to have a similar issue I can't figure it out.
Would restoring Mountain Lion completely by using a USB jump drive solve this problem? I have an external hard drive that uses Time Machine to back up my MacBook so a complete restore shouldn't be an issue.
Any advice would be greatly appreciated!
Thank you!
P.S. This is what my disk utility currently looks like...

You can try to use Boot Camp Assistant to completely remove the Windows partition but it might not work.
Simple fact is once you setup a Windows partition you can't fool with it at all, that is unless you use some add on program specifically designed to do that on a Mac computer. If you need to resize the Windows partition you first need to use BCA and remove the partition completely and then recreate it at the new size you want and reinstall Windows.
You might have to use Time Machine and backup your Mac partition then repartition the complete drive and then restore from that Time Machine backup. Then setup the Windows partition and reinstall Windows.

Need help recovering from a BIOS upgrade failure

I was helping someone with their laptop and it was not responding well so I decided to reboot the system (user normally puts it to sleep). Screen went black after reboot, no BIOS screen or blacklight. I connected an external monitor and was able to see everything fine. Did some research in the knowledge base and found the following article which suggests making sure you are running the latest BIOS.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01997899&tmp_task=solveCategory&cc=us&dlc=en&lc...
"As a final action, if there is an image on the external monitor and you have installed the latest BIOS, updated CPU chips set, and updated graphics drivers but the notebook display remains black, the LCD may be defective. It may be necessary to contact HP for technical assistance or send the notebook for service to replace the display."
Seeing that it was running an older version I decided to update it.
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-89419-1&cc=us&dlc=en&lc=en&...
Watched the update (it mentioned that it was backing up the old bios) and when it had flashed the 16 blocks the external monitor went black (not sure if it was rebooting) and nothing happened. Waited over 10 minutes figuring it was doing something. Turned off the laptop and turned it back on again and the only thing that happens is the caps lock light blinks with no pause. Num lock light is on solid. Also it will not power up without the battery installed.
Here are the specs:
HP Pavilion dv9580us
Product# GA334UA
Windows Vista 32 bit
Original BIOS version F.09
Updated BIOS to version F.5 using SP48024
I have looked at various articles like the following but not sure if they apply to this model.
http://h30434.www3.hp.com/t5/Notebook-Lockups-Freezes-Hangs/Fixing-A-laptop-which-had-had-a-bad-BIOS...
Tried connecting a USB floppy drive and holding the "Windows"+"B" or "FN"+"B" or the 4 arrow keys and it doesn't try to access the floppy drive.
What I am hoping for is that someone from HP can tell me what is required to do a bios recovery for this model which was manufactered in 2007. There is not a "HP_Tools" partition.
Can I do a recovery with only the external monitor working?
Do I need to use a USB drive or floppy?
With only the BIOS software (link above) how do I extract the files for the USB drive or floppy?
Any help is much appreciated. God Bless,
John

i was wondering what you meant with "label file". an alias.
but it's a bit strange. the "send registration" alias points to a document called Send Registration.setup which in turn is executed by Setup Assistent.app. the alias and the document are 4KB in size each. the app about 45MB. it's just a simple app, that asks for your personal data, like name, adresse, e-mail and so on, to register them with apple, if you choose to do so. no way that it suddenly mutates to 15GB.
and indeed, deleting the alias would have no effect on the system. so i strongly assume you've deleted something else accidentally.
fire wire target mode. yes.
start the macbook pro. connect it via fire wire cable to your macbook. then boot the macbook while holding down the "T" key. the macbook should now show a big fire wire drive icon on it's grey bootscreen. on the macbook pro the internal drive of your macbook will now show up as a mounted firewire drive like an external hard drive. you can then access it from the macbook pro to copy your data from it onto the macbook pro or another external harddrive connected to it.
after that you can dismount the drive and power your macbook down. insert the install dvd, that came with the macbook and hold "C" key while booting it up again. it should now boot from the dvd and open the os x installer. select your language and reinstall the system.

Need help recovering from glibc upgrade [SOLVED]

I recently did pacman -Syu on a system because I was having trouble with a softphone utility. I installed Arch on this laptop perhaps 6 months ago and have not done many upgrades since that time. Of course I've been waylaid by the recent glibc changes and I'm trying to recover. I think I've gotten a good deal of the way there by researching the issue and attempting a few solutions. But I'm quite confused by what I'm now seeing, so I want to ask for help here.
First, let me point out that I posted in this forum yesterday about certain events that led to my problems--see that thread at https://bbs.archlinux.org/viewtopic.php?pid=1186089. Essentially, I followed the wrong set of instructions and did pacman -Syu --ignore glibc pacman -Su before doing pacman -U http://pkgbuild.com/~allan/glibc-2.16.0 … pkg.tar.xz. That broke pacman, which, being the most current version, was expecting that glibc version to be on the system.
To remedy the problem I followed the procedure outlined in that thread--namely booting from a USB drive on the affected system and running pacman -U http://pkgbuild.com/~allan/glibc-2.16.0 … pkg.tar.xz --root /mnt/brokenRoot. Things kinda started to work then: pacman would run, but I noted that my mouse cursor was not responding. I decided to try and finish the upgrade and so ran pacman -Syu again using the --ignore glibc switch as suggested at https://wiki.archlinux.org/index.php/De … iki:usrlib.
Things started to get really weird after that. For example, at a certain point during the boot process--I believe when the console is getting ready to switch to framebuffer (or whatever point that's called where screen resolution changes from vga)--and the screen just freezes. The laptop won't accept any keyboard or mouse input and just appears to be hung. I was able to chroot in to the system and cause the sshd daemon to start though, and have discovered that I can ssh in and do things.
I upgraded the kernel again today in an ssh session, which gave some quite strange results: mkinitcipio is searching for modules under /lib, whereas as I understand it, /lib is now supposed to contain nothing and is to be simply a symlink to /usr/lib. But I can't build an init image on this system unless a /modules directory is present under /lib. Well, the /lib directory was there, so I symlinked /usr/lib/modules to /lib and mkinitcpio ran fine after that. So what's up here? Why is mkinitcpio expecting the /modules directory to be under /lib?
Just as weird, there seems to be a newer glibc version. But I can't upgrade to it: I get the message "glibc: /lib exists in filesystem." Now, having read https://wiki.archlinux.org/index.php/De … iki:usrlib I know that there are suggestions for remedying this. But when I run the commands suggested there to try and find out what packages own files in /lib, it looks to me that all files there are owned by glibc 2.16.0-1:

Long story short, I'm quite confused by this. And I have a barely-working system I need to fix.
Can anyone please offer input on what might be going on with this system? And perhaps offer suggestions for straightening out the mess?
Thanks,
James

Ok. So I'm officially dumb--in case that wasn't already apparent. I thought I'd tried upgrading glibc after I'd deleted the symlink to /usr/lib/modules (I deleted it a couple of times). But I was apparently wrong: after just now deleting it upon reading your post, I see that the upgrade has worked and that the system reboots into its former normal state. So. it looks like it's fixed and like this thread can be marked solved. Still I'm curious: will mkinitcpio continue looking for modules in /lib?
Thanks,
James

Need help recovering files form external drive!

Well, I made a stupid mistake this morning. I am used to the Windows style of copying where if you have folders with the same name and it asks if you want to overwrite the folder, it typically merges the contents.
Apparently in OSX, when you overwrite a folder, it removes the content from the previous folder and proceeds to copy the folder..
So I went to backup from my laptops drive to my external and I copied the folder and it asked about the overwrite and I said okay and instantly had the thought that it was a bad idea and stopped it after only two images and the drive works perfectly fine, just missing a lot of images.
So how can I recover these images? I haven't used the drive since to ensure that I didn't overwrite the files... What recover software do you recommend for OSX? Especially looking for a free solution.. I don't have $80 to plop down on a more conventional program. Also, are there programs that can place the images in the folders they came from? Would take a while to try and restore my folder structure as well...
I did try the program PhotoRec that is free and open-source but it searches the whole drive and can't focus only on deleted files with the HFS+ file structures, which means there will be TONS and TONS of images that it 'recovers' that are already just fine on the drive.
Any help is GREATLY appreciated! I 'lost' nearly the whole years pictures. But I know they are all still there.
Thank you, thank you, thank you...

There isn't a free solution for data recovery, and even the commercial solutions may not be able to recover all the files, since you had already started writing to the drive.
More importantly, you said you deleted files from your backup drive, right? So, if it's a backup, don't you still have copies of those files elsewhere? If you don't, you need to quit thinking of this drive as a backup, because it isn't a backup if it contains the only copies of the images on it.

Need help recovering .dmg files from an accidentally reformatted external hard drive

Help?
I went to make a copy of an important drive and accidentally re-formatted it (re-formatted mac journaled, originally mac journaled). The drive contained a bunch of important disk image files which I need to retrieve whole. I'm fairly confident that the files are still there and only the table information got overwritten, as the re-format took about 30 seconds. None of the recovery software I've seen however, can retrieve .dmg files, or such large files (these are up to 32 gb each in size).
Any suggestions on how I can retrieve these disk image files?

I need help with creating a partition with bootcamp. I run OSX Lion and want to also run Windows 7.

Bootcamp is not allowing me to create the partition. The message i get when i try to do so is as follows:
The disk cannot be partitioned because some files cannot be moved.
Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.
I am looking in Disc Utility and am not sure what to do.
To me it looks like i only have one 'single Mac OS Extended (Journaled) volume. So i am not sure exactly what it is requiring me to do?
Help greatly appreciated!

Look to the right under "More Like This". Your issue has been discussed many many times. The error you are seeing is because you do not have enough free "contiguous" space on your hard drive. Read the other threads that address this issue to find how to solve the issue.
Or, put "The disk cannot be partitioned because some files cannot be moved" into the search box at the upper right of this page.

Need help converting SQL "OVER (PARTITION BY )" to JPQL equivalent - JPA

Having trouble converting this query:

TO_CHAR(sdt, 'yyyy-mm-dd hh:mi:ss AM')
from
select
sdi,

where x.sdt = x.MaxDate1
and sdi in (1234,2345,3456,4567,5678,6789,7890);
to JPQL equivalent using JPA
Able to convert simple queries but I do not know how to handle the "over (partition by sdi)" portion of the query.
Can anyone help
TIA

Why have the power (and cost) of Oracle and then not use those powerful features because you are restricting yourself to a vanilla set of SQL because you are using some generic framework.You know how it is :
1 - Application developers create code & queries but only test them on tiny database with low volume and no concurrency at all.
2 - Application goes Live, Database grows (as expected) but stupid optimizer is not as fast as on test environment (that was mostly empty)
3 - Queries are now 200 times slower.
4 - Expensive DB expert comes and gathers statistics, creates indexes, rewrites queries, uses hint/outline/SQLprofile.
Conclusion : Database is evil and prevent application from working efficiently, the proof of all that being : nothing had to be done on application's side to make things work correctly. Database is declared guilty.
Which could translate to :
1 - Team buy a formula one with 800HP that can reach 200mph in less than 10 seconds.
2 - Give it a pilot that doesn't even want to understand what-the-heck is a gearbox/transmission. Pilot only drives in 1st gear.
3 - The formula one is now doing 0.003 miles per gallon, doing the hell of a noise, and is limited to 80mph +(any $10000 family wagon is faster in average)+
4 - Expensive expert comes and check everything in the formula one. Finally understand the problem and modify the gearbox to a sloppy automatic transmission
Conclusion : Formula 1 is evil and prevent pilot from being fast. The proof of that being : nothing had to be changed on pilot's side to make things work correctly. Formula 1 is declared guilty.
You cannot win race without understanding how the car/engine/transmission/physics/race rules work.
Too much levels of abstraction is bad. Treating the database as a black box is the most seen "Bad Idea" these days (to my point of view).
Warning: I am biased towards Oracle :-)And so am I.

Re: Need help recover the Satellite A100-522

Dear All
I have a notebook and when I turn on could not found operation system error apears.
I wanted to revcovery, but when I want to do it preaze in the first step.
Also I wanted to do installation with new XP but I cannot delete drive C and install new windows.
I was wondering if you help me

Hi
If you want to recover the notebook using the Toshiba recovery disk then you have to put the disk into the CD/DVD drive and have to boot from this disk.
You can press the F12 button while powering on and the boot menu will appear.
Then choose the ODD (CD/DVD drive) as a boot source and the installation should start.
Then follow the instruction on the screen.
You can also use the original Windows CD for the OS installation.
You should boot from the XP CD and you will see that the setup will start.
But note buddy; if you will be not able to start the installation then an HDD fault is possible. I got a message that the OS was not found on the HDD and this issue was related to the HDD malfunction.
In such case the HDD shoul be replaced

Need help Cloning a Bootcamp partition

I need to install a larger hard drive in my Leopard MBP that has a HFS+ and a FAT32 partition running Win XP.
Moving the HFS+ partition is no big deal, but I really could use some step by step guidance in moving the contents of the existing FAT32 partition to a new and larger FAT32 partition.
I essentially need to backup to an intermediate drive, and then to the new larger target drive. I have been trying to use Disk Utility, but am unable to get a partition that is bootable. I have tried doing a "throwaway" WinXP install on the partition, but am unable to write over the files there, because many of them are locked. I am not running NFS.
Any guidance would be appreciated.

I'm not sure if this will work, but.... What if you used the Microsoft Backup Utility to back-up the files to an external hard drive (you will need an NTFS partition on the external), use bootcamp to create the larger FAT32 on the new drive, install a fresh copy of windoze on the new drive, then use the Microsoft Backup Utility to restore the files from the external hard drive.

Need help with understanding updates, partitions, firmware etc.

I went to update my QuickTime and in doing so was told to update my OS which included QT updates. Now I'm getting all kinds of messages about partitions, firmware etc. do not understand at all what's going on.

THIS IS MY STEP BY STEP situation with my updates:
I go to the Apple Icon and selected Software Update and it reads I have 2 items:
MacBook EFI Firmware Update 1.2
MacBook SMC Firmware Update 1.4
I select Install and then it state Installs completed successfully.
BUT THEN I recieve and new icon and this message below:
To update the SMC firmware on your MacBook:
Your computer's power cord must be connected and plugged into a working power source, or your battery must be at least 25% charged.
For more information see 'http://support.apple.com/kb/TS3499'.
1. Quit all other open applications.
2. Click Restart in the MacBook SMC Firmware Update window and wait for your computer to restart.
The SMC firmware update starts automatically. A status bar indicates the progress of the update. During the update your computer fans will run at full speed, but will return to normal once the update completes.
Important: Do not interrupt the update.
Your computer restarts automatically when the update is completed and opens the MacBook SMC Firmware Update.
3. Click OK. The SMC firmware is now up-to-date.
If these instructions appear on your screen again, the SMC firmware update was not successful. Repeat steps 2 and 3.
I follow the instructions and then I get this: (could get my image to attach but here's what it said)
the first error message heading of:
MacBook SMC Firmware Update 1.4
Your firmware could not be updated, the hard drive partition scheme may not be supported. You must be booted from a GUID partition or RAID scheme.
see http://support.apple.com/kb/HT2434 for more information (internal error 28:3)
THEN ANOTHER ONE POPS UP saying:
Your Hard Drive partition scheme is not supported, you must be booted from a GUID partition scheme.
see http://docs.info.apple.com/article.html? artnum=303609 for more information
I went to those URL and tried to understand what it was telling me but I did not understand. I can't figure, by reading thru forums, etc, if I need to do this or not and what exactly it is.
So back to just pushing a simplet update has thrown all this unknown info. my way and I have no clue what to do.
Thank you. Hope this is more clear.
