[SOLVED] Grub crash: seeking non-existent device

A couple days ago, I did a successful fresh install on another computer. Today, I took my hdd from my old system and added it as a slave on IDE1. I didn't move or make any changes to /dev/sda (arch hdd) and BIOS successfully recognized the second hdd.
Then when I boot, Grub complains:
error: no such device: [some UUID]
grub rescue>
At this point, I'm assuming it must by the UUID of my first hdd and for some reason, it can't find it anymore.
I should mention here that when I partitioned /dev/sda during installation, I used GPT, not MFT. Since this computer is an older Dell that I'm resurrecting with Arch, it has an older BIOS, which means that gdisk had to create a very small bios-boot partition to make it somehow compatible with the BIOS. I mention it because I'm not sure if that plays into any of this.
Next, I boot the arch-install iso "ARCH_201310" off my keydrive, then blkid to see the UUIDs of both hard drives...nothing matches the UUID that grub complains about. Then I go into gdisk and check all the UUIDs for disks, partitions...find nothing that matches. I check my grub.cfg and it's not in there either. Just out of curiosity, I regenerated my grub config and reinstalled grub (after arch-chroot, of course) and then rebooted. Got the exact same message! I'm totally at a loss now. I have no idea what's going on. I'm hoping the forum can help...so I don't have to go through the hassle of doing a fresh install all over again. If it makes any difference...here's some output from the grub shell...I tried ls everything listed, but it couldn't find any filesystems.
grub rescue> ls
grub rescue> (hd0) (hd0,msdos4) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (hd1) (hd2) (hd2,msdos2) (fd0)
Not even sure why it listed (fd0) since I removed the floppy drive and turned it off in BIOS

So just for the sake of completeness, in case anyone in the future has a similar issue and stumbles across this thread:
The reason grub was giving an error about a non-existent device with a UUID which didn't belong to any of my current devices or partitions was because it had belonged to a previous installation on the same drive...one whose /boot was on the primary hdd of my previous computer. I think I may have also mistakenly installed grub on the second hdd at that time, instead of on the primary one...so long story short, there were some artefacts on the MBR of the second hdd which grub was finding and complaining about.
There were two possible solutions to resolving the boot failure: chrooting to my arch partition and re-installing grub, first on the second hdd, and then on the primary hdd; or the second option of removing the 55AA signature on the second hdd with a hex editor. After choosing the simpler option of reinstalling grub on both hard drives, I then switched my second hdd back on in BIOS and rebooted normally.

[SOLVED] GRUB crashed after pacman -Su

Hello all,
I did a system update about 2 hours ago, I did pacman -Syy and pacman -Su. Every thing looked normal.
Restarted and system crashes right in GRB, it doesn't even shows the menu or error message, it just fills the screen with "GRUB GRUB GRUB GRUB GRUB GRUB GRUB".
I checked the disk, partition tables are ok, and the whol HD looks ok, no errors at all (checked with system rescue cd, a gentoo live cd).
I also mounted the boot partition, all files seem to be ok, grub menu, etc..
/grub/menu.lst was modified today, but looks ok.
Any Idea of what could happen?
How to solve it?
Should I try to replace grub?

Thank you hcjl and demian.
Problem solved after GRUB re-install.
Here is the procedure (resume from hcjl links) I made, just in case someone else needs it:
1- Download the arch iso and write it to cd or dvd
2- Run the cd, login as root
3- Mount arch and boot partitions:
-Find boot and arch partitions with
fdisk -l
Create a directory where you would like to mount the arch partition, then mount it:
mkdir /mnt/arch
mount /dev/<device-or-partition-name> /mnt/arch
4- Changing Root:
cd /mnt/arch
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
Mount the boot partition:
mount /dev/<device-or-partition-name> boot/
And change root:
chroot . /bin/bash
5- Install GRUB on hd0 (first hard drive):
# grub
grub> setup (hd0)
6- Exit all, reboot
That fixed my problem, and preserved my original GRUB menu (I did a backup of broken GRUB, but it was nor necesary)
Thank you all for your help.

FMLE 3.1 Mac Non existant devices?

Just getting started with this and I am hitting a bump in the road. I have a Sony HVR-Z1U camera connected via firewire and in the devices drop down the only thing being shown is the Built in isight. How do i get the external camera recognized?

Does that camera provide raw format?

Import prompt for non existent device

Every time I launch LR 2.2, if prompts me to import from my iPod Touch, which is not connected to the computer. It displays one blank image. How can I stop this from happening? When I plug in my compact flash card, I do want it to bring up the import dialog, which it does correctly.

Claude-
Import the bogus image, then delete it, that is, if you can import it, whatever "it" is.
I'd like to not have my iPhone come up for prompting, as it does have images on it that I don't care to import.

First off, i think it's sad that i have to use my non apple device to post this question... Why has my iPad become absolutely useless after updating to iOS 8.1? I am unable to use my mini because it crashes, slow performance, major battery drain.

Restore iPad to Factory Default; do not restore from backup. It may be the cause of the problem.

Non-Controllable device load crash

I am loading into my system under the Capture Settings with Non-Controllable Device. I have been able to capture video successfully through this setting before, but the clips were only 1-2 minutes. I am trying to capture a clip that is 8-10 minutes. So after I have finished the live load and the clip is finished I press Escape to end the load. When I do that the preview screen continues to stay up and the rainbow wheel starts to spin. That is when the crash occurs. I do a force shut down and when I restart my media drive is full. It seems that the video file that was being created is now as big as the how much free space was available when I began the load.
I have been able to capture files up to 30 minutes in the past in non-controllable device mode, but now every time i try to capture it crashes. And I have a deadline friday. Please help.

Make sure you have set a Capture Time Limit. Here's why....
When you use Capture Now, the disk system is being asked by FCP to essentially "keep capturing until we tell you to stop ... and no, we don't know HOW much that will be either." It is stressful on the system to be continually wandering around looking for space to stuff those ones and zeros with out any sense of how many they have to accommodate. One solution available to the system is to allocate the ENTIRE empty space on the disk as the potential capture file. This essentially locks the machine as there is no headroom for basic disk operations.
However if you set a limit on capture now, say 60 minutes, the disk system can allocate the space and may seem to be less confused by the process. It still does not know EXACTLY how much you want, but it knows you will not want MORE THAN the limit and therefor can reduce some of the uncertainty.
Better yet is to record to a timecode addressable tape. This allows you to log the tape, then use batch capture. When you do this, the system knows EXACTLY how much space to allocate for each file and is very efficient.
Good luck.

[Solved] grub-install hangs

I have an install of ARCH linux on a 2 partitioned hard drive with Ubuntu on a separate partition. Originally the drive contained a 64 bit version of Ubuntu on the first partition. I moved the drive to a different (32 bit) computer and installed 32 bit Ubuntu on the second partition. I then reformatted the first partition and installed 32 bit ARCH running update-grub from Ubuntu which found the new ARCH installation without any difficulty. As this seems to be becoming my main distribution I would like to reinstall grub2 from ARCH. I installed grub2 from the extra repository (1.98-5). When I enter 'sudo grub-install /dev/sda' the command hangs indefinitely. I attempted this in single user mode as well.
I did note the following appearing in /var/log/errors.log and the kernel log:
Aug 18 14:02:46 localhost kernel: end_request: I/O error, dev fd0, sector 0
.. (repeated several times... eventually...)
Aug 18 17:20:54 localhost kernel: Buffer I/O error on device fd0, logical block 0
This seems odd as I don't have a floppy drive connected. Running grub install with the --no-floppy option produced the same result.
EDITED TO ADD: It appears as though the floppy drive related errors are occurring specifically when grub-install is executing. Further they seem to occur when the --no-floppy flag is included. It appears as though the script is stuck repeatedly trying to access the floppy drive despite the flag.
EDITED WITH SOLUTION: I disabled the floppy drive in the system bios (no drive is/was connected) and grub installed without issue. I didn't realize I had the non-existent drive enabled as oddly ubuntu had no problem with installing grub while the ARCH version ignored my explicit instructions to disregard the floppy drive.
Any suggestions most appreciated!

Imac no longer "sees" shared non-Mac devices on network

Hi everyone,
Here's a real puzzler (for me anyway). I have three Macs, two PCs and an Escient digital jukebox on the home network over standard router-based ethernet connections. The system has worked great especially since Leopard came out and automatically detected the non-Mac devices and added them to the shared category on Finder. Suddenly in the last couple of days I noticed that although the Mac devices are still on the shared network, the PC hard drives and the Escient jukebox has mysteriously disappeared. All of the devices work properly, and I have made no changes in my network recently.
Any thoughts on diagnosing the lost shared devices and restoring them? I tried Time Machine, but it acted also as if those devices never existed. Thanks for your help!

Hmm yes.. this is a strange one.
You could try this as it appears to work with a couple of tests I ran.
Open your Network Preferences pane from  > System Preferences.
Make a new location.
For which ever interface you are using, be it Wired (Built In Ethernet) or Wireless (AirPort), click the "Advanced" Button. Click on "WINS" and enter the workgroup name of your other Windows Devices (Default is usually WORKGROUP) into the Workgroup drop down menu.
You can also use the menu to see if your mac can see any other workgroups.
Click OK, Click apply and see if it worked.

My iPhone 5S prompts me for my password to an Apple ID email that no longer exists as an account. How do I change my Apple ID address without having to change the primary address to a non-existent email account?

I cannot sign into icloud on my phone because the Apple ID is an email account that has been deactivated and deleted. How can I change my Apple ID without having to change the primary email address to this non-existent account? If I did so, I wouldn't be able to access the account to receive the verification email. Please help!

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iDevice, then sign back in with the ID you wish to use. When you do this you may find that the password for your old ID isn't accepted. If this should happen, and if your old ID is an earlier version of your current ID, you need to temporarily recreate your old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You should not need to verify the old email address. You can now use your current password to turn off Find My iDevice on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud).

Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

HT5616 I have an apple id; but when I try to sign in to iCloud, I get the msg that the apple id is not an iCloud account. However, apple was able to bill me for my non-existent iCloud account. How does that happen?

If you didn't create an iCloud account on an iOS device or Mac, you don't have one. You can't create an account on a PC. If you were charged for an iCloud storage upgrade without having an account, contact the Apple online store at the bottom of this page for a refund.

I can't find my previous ??? concerning if it is possible to load songs from a "non-apple" device into iTunes

I can't fnd the question I asked in here roughly an hour ago - concerning if I can load songs from a "non-apple" device. I have a SanDisk that I'd like to load my songs into iTunes - is this possible?

A.C.,
These links will give you several methods of recovering whatever songs remain on your iPod; some free, some third-party software, some more comprehensive for restoring Playlists, Ratings, Play Counts, etc. Read them and their associated links before deciding on a strategy that works for you. There are many various third-party software programs that will offer a more robust process, or an easier GUI. Do a Google search for them if the links below leave you wanting…
Don King Resurrected: Deleted files from hard drive (free user steps – music recovery only)
MacMuse: Computer Crashed (free user steps – music recovery only)
Copying music from iPod to computer (a primer on various methods and software)
Copying Songs from Your iPod to a Mac or PC (resource for 3rd party software)
iPodRip Software
PodUtil Software
Senuti (Mac OS X v10.3 or higher Recovery Utility)
XPlay (Software For Music Recovery &/or Cross-Platform Functionality)
XPlay Photo Browser (For recovering Photos)
After recovering your song files, strongly consider developing a thorough backup strategy for just this type of situation (and many other potential disasters).
You need at least two full sets of your music, not including what is on the iPod:
-- One full set on the PC within iTunes (on internal HD or ExHD)
-- One full set on an separate external backup medium (CD/DVD/ExHD/other)
-- One (full or partial) set on the iPod
Music files on just the iPod and only one other medium is not considered having any backup.
If you cannot store your complete music files on the computer’s internal HD, then create and maintain at least two external sets (any multiple combinations of ExHDs, DVDs, CDs).
Backup both the music files and the Library database file (iTunes Library.itl). What are the iTunes Library files?

Changed my Apple ID email, but ICloud does not recognize my new login, only my old one (which is now non-existent) HELP!

Changed my Apple ID email, but ICloud does not recognize my new login, only my old one (which is now non-existent) and requires the password to do anything. Everytime I go onto the ICloud page it shows my old email and requires the password, but I can't exactly type in a password because that won't work. I can't find a way to change my email or delete ICloud.

If the old ID is an earlier version of your current ID, do the following:
Make sure you are signed into iMessage and FaceTime with your current ID. If they are signed into the old ID, go to Settings>Messages>Send & Receive and Settings>FaceTime, tap the ID, sign out, then sign back in with your current ID.
Then temporarily recreate the old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. (You should not have to verify the old email account so it doesn’t matter if you no longer have access to it.) Now go to Settings>iCloud, turn off Find My iDevice and enter your current password when prompted (even though it prompts you for the password for your old ID). Then go to Settings>iCloud, tap Sign Out (or Delete Account if you are not running iOS 8) and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address back to the way it was. Now you can go to Settings>iCloud and sign back in with your current iCloud ID and password (your data will download back to your device).

How to delete iCloud account, with non-existing email as ID, on iPad?

Cannot delete iCloud account (which happens to have a non-existing ID) on iPad in order to have same account as on iPhone - keep trying using current Apple ID and PW but to no avail - iCloud settings continue to insist that Apple ID/PW is wrong but they are the ones I have in "manage my ID"???

If the ID is your the iPad is signed into is your old ID, and if your new ID was created by editing the details of this old ID (rather than being an entirely new ID), go to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPad on your device, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.
