Ubuntu :: Unable To Reformat External Hard Disk From Ext4 To FAT / Fat32
Aug 19, 2011
I tried to install ubuntu 11.04 on my external hard drive (WD My Passport, thats all i remember about the name) and all was well, until I tried to reformat it from ext4 to FAT, and no such luck, it isn't even being READ, not in fdisk -l, not by gparted, disk manager, or anything else. Windows is no help at all... I tried that out of desparation.
Just installed opensuse 11.3 Kdeversion on my laptop. Before installing it on live mode i had a problem of accessing my other drives (NTFS, FAT32 and EXT4) which said HAL system policy...etc mounting error. I could access all drives with root privilege. I thought problem will be solver once i install opensuse on my system. How ever i was really disappointed after seeing the same problem post install. Googled around for the solution and got this link
After this the problem got worse now i am not able to see any of the drives in the side panel. Gone through many forum and posts all discuss about external USB HDD.
I wanted to make a clone of my drive, so I tried the ole sudo dd if=/dev/sda1 of=/dev/sdg1 trick, but first I formatted the drive to the Ext4 format. I wish I would have understood that format a little more before I decided to format it that way. Now I can't access my drive at all. I read almost everything on the net about manually mounting it, but almost everything was in Fat, NTFS, or Ext3/2 format. I even read the Ubuntu documentation. I don't know if it's because my drive is in Ext4 format, or if I'm just not doing something right.
As you can see in the following picture, it recognizes the drive, yet I am unable to mount it. I am trying to access the 160 GB drive. I even tried to see if Windows would recognize it. No go. Today while lurking in the Ubuntu Forums I found a way to make a live .iso of my system (which I think is awesome). So now I want to reformat my drive and use it as storage once again. I think I will restore it to NTFS. I thought that the Ext4 format would work better in Linux (which I was wrong), but now I need Windows to recognize it as well, and it needs to be able to store files bigger than 4 GB (unless you have a suggestion on what to format it as).
I was trying to reformat my Seagate external hard drive and I selected "free Space," in disk utility not realizing that the computer would no longer recognize the device. I'm trying to install Snow Leopard on it so now how do I format it now to the GUID format? I luckily backed up the entire contents of the hard drive (The essential files on it), but what do I do now that the computer doesen't recognize it!?
This is Mushtaq here. I am using CentOS 5.3. Everything works fine regarding Hardware Support except of External Hard Disk. I have a HDD Western Digital 80 GB in USB converted case. Its working fine under WinOS, Fedora 10 / 11 / 12 + & RedHat Enterprise Linux. But CentOS is unable to access it even it does not detect it (fdisk -l command is used to verify the connected disks). Can any one please help me in this regard, I am fed-up of this situation.
I have a FAT32 external USB hard drive with a bunch of stuff I want to copy onto a RHEL server. Is it as simple as it is on a Mac or PC where I just plug it in and it will show up, then I can copy all the files off of it?If it is, how do I safely remove the drive after I'm done with it?
I had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?
i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.
OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?
Recently my laptop broke down and wont start up. I'm currently trying to recover my files to my mac with an IDE to USB cable. It recognized my windows partition fine and I was able to get all my files off of that, but the majority of my stuff is on the ext4 partition that I have on it. Does anyone know how to access the ubuntu partition of this hard drive from my mac?
Tuesday night I wanted to make a backup of my Ubuntu ext4 partition via Clonezilla so I configured that an image had to be made and it would be saved on the NTFS external disk. But it said it needed 23 hours to create a 5gb backup, so I resetted my computer as this took too long. But after this, Ubuntu nor Windows recognized my drive.
I called Seagate and they told me after troubleshooting 30 minutes, that there is no option of fixing the drive and I had to send it to RMA. What could be wrong? Clonezilla works via a bootable ISO on Debian. The disk drive is still spinning. I already rebooted the external drive, but it's not working. In Linux the disk is no longer mounted and cannot be mounted:
Code: brw-rw---- 1 root disk 8, 16 2010-03-12 00:50 /dev/sdb brw-rw---- 1 root disk 8, 32 2010-03-12 00:50 /dev/sdc brw-rw---- 1 root disk 8, 48 2010-03-12 00:50 /dev/sdd brw-rw---- 1 root disk 8, 64 2010-03-12 00:50 /dev/sde
What could have happened? Would the data still be accessible on the internal drive? Did I just loose 1.5TB data that was stored on the external disk?
I recently bought 320 GB Trancend external hard disk and working fine days back.Earlier i could copy from and to the hard disk with out any issue. I dont know what happened after that now i am not able to write any files in to the external hard disk. This is not NTFS formatted device. here is some of the out put from terminal.
Code: sundar@sundar-sundar:~$ fdisk -l Disk /dev/sda: 120.0 GB, 120034123776 bytes
whether all 2TB external hard disks will run on ubuntu 10.04 (lucid)? I was under the impression that Seagate and Western Digital would, but the store where I went to buy it told me they won't. I really need to buy an external hard disk as I'm running out of the space
I have just updated to karmic, and I found that my external hard disk partitions, previously mounted under /media/disk and /media/fat are now referenced by something looking like a UUID, namely /media/7b096ea4-60ee-46b1-95cd-1851b051c40d and /media/4951-95D9.
Is there a way to revert to the old settings? Any application relying on the files on the external hard disk has now stopped working. While I certainly could just change reference (assuming the UUID does not change every session), I'd rather use the old names if possible.
I've 2 computers (one at the job, one at home), different motherboard types but same chipset, having AM2 AMD CPUs but different clock speed. I don't have (I don't want to buy) internal hard disks for these computers.
I would like to buy one external USB HDD and install the latest Ubuntu. I will carry this HDD to my job and my home. Is it possible to use this HDD as boot HDD on both computer? Even they are not same just similar? Is this a problem for Ubuntu?
my old pc died not long ago so I retrieved its hard disk and bought a USB enclosure. that HD had a ubuntu 9.04 partition and an XP one. Something must have gone wrong somewhere as, although i could still boot from jaunty, I was not allowed to upgrade.
It therefore seemed to me natural perform a clean install, so here's what I did:
- on a win7 computer, I inserted a 9.10 bootable disk
- with usb-disk creator, I wanted to install via a spare image so re-formatted the HD
- I couldn't install a mythbuntu 9.10 after that as I giot an error message ("can't mount the drive" or something similar). yet, in win7 the HD is recognised.
So, what am I doing wrong? Are USB HDs not included as USB devices that you can make bootable? Or should I be installing a !straight" ubuntu version, then install MythTV?
My ubuntu login window seems to be chrased and seems no way to restore it. I was planning to move ahead with reinstalling it but could any1 tell me how can i copy data to external hard disk. I am in Mannual restore section with promt staying at root@ubuntu :/#
Just bought a 'my passport essential' wd external drive. Before putting anything on it I want to get rid of the partition that holds a windows exe for backing up and some security features. Not sure whether its a hidden partition but wondered whether the on-board disk utility could achieve the same as 'f' disc used to.
I have this unique situation, I think. My TV plays certain files only through external USB storage. My Ubuntu server stores all of these files on local hard disks. I do not want to buy an external hard disk and then keep moving it between both. Now, strange as it may sound, is it possible to somehow connect my server to the PC and expose a given local hard disk connected to the server, as an external USB drive to the TV?
