Ubuntu :: 640 GB External HD Not Recognized Correctly?
Mar 12, 2010
I bough a 640 GB external USB disk.I found something wasn't working well when I couldn't restore a backup from the disk (with sbackup).So I tried to convert the filesystem from fat32 to something newer.I installed gparted, and it shows no partitions on the 640 drive (however, I can access the filesystem!!!). Also, for some reason it shows as a 298.08 GiB drive.So I thought I should format it to solve this. When I tried to do this, gparted simply closed, with no error messages.

I had windows 7 installed on my machine and decided to go with a ubuntu win7 dual boot. The install went fine, but Ubuntu doesn't see my second HDD as anything but empty. My second HDD I set up in win7. It is actually two 320GB HDD striped together. It is holding alot of data that I would like to be able to access from both win7 and ubuntu.
When I run fdisk -l in the terminal I get:
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xf1c572ca .....
So Ubuntu sees the two HDD, just not as one with all my data on it like I see it in windows. Is there a way to set it up so I can use that second HDD (the two stripped) in both win7 and Ubuntu?

When I boot my computer, I can see dvd-rw drive detected correctly, though 9 times out of 10 it does not get detected by OS - drive's icon is not present in nautilus hence I cannot access any cd or dvd. Although when I restart a computer and try to boot from cd or dvd - it works perfectly, then after coming back to the os the cd/dvd won't be accessible. I a have Fedora 13 installed from the DVD ISO.

I just finished up a Clean install of Suse 8.2 (from BOXED set I bought back in the Days-from Best BUY.) everything seems to have gone well. I set the DMA on my ide drives ok. Under Yast ,it did have K3B RECOGNIZE MY cd-r iomega ZIPCD1024INT-A , it says it is recognized as acdwriter ,but when I go to k3b disk copy function,the whole cd copying process stops ,saying my cd-rom is not cdrDAO compatible. WHAT is going on???? Is this CDwriter too old for this Suse 8.2???

Esteemed (K/X)Ubuntu'ers, I need some help. I had a Samsung HDD (Internal) that crashed, was a fault of the store that sold it to me and they went bankrupt. I thought I buy an external HDD (Western Digital Elements 1.5TB) and boot Kubuntu from there, so I still use the computer till I buy a super nice one after USB 3.0 hit the streets.
The problem I keep having by booting of the external HDD is that GRUB keeps saying Code: error: bad filename how to install Kubuntu on a external HDD and make it boot correctly?

Jaunty is fully updated but SUDDENLY is not recognizing external devices (card reader, camera, DVD inserted in drawer, etc.) In other words, I cannot see my media and, therefore, cannot open it.
Anybody else having problems here? What's up? Did something go wrong in the updates?
(AMD64 running stable Jaunty 9.10 fully updated)

I got this 1Tb Toshiba external about a month ago, and recently I started really using it to share lots of media files. What I've noticed is that it turns itself off after a few minutes of inactivity -- I researched this issue across the internet, and found that it's between 5 and 30 minutes, depending on who's writing about it.
I found a person who posted a DOS batch file, which (i think) continuously accesses the drive as long as the batch file is running. I'd like to find a way to do that in linux. could someone point me in the right direction?
i took a few minutes to plan it out... i think i need a loop that will access the drive (or do something to it, at least) once every minute until i close the script. I'd also like a message box that shows up that says something like "while this is open, your HDD is being accessed".

I've recently brought a Western Digital Elements 2TB external hard disk and have been planning to encrypt it for use as a backup drive. However, it seems that these 2TB disks use the new 4K sector sizes and thus need to be handled more carefully than the older 512K ones.
After spending a week looking on Google, I have to admit I'm pretty confused and hope somebody here might be able to verify my conclusions
The drive reports that it's a 512-sector drive which is probably false. Using fdisk -uc, the original partition starts at sector 2048 so I assume that is a valid sector also to start a dm-crypt partition overwriting the previous one?
I've also read that every layer that is added to these drives must support the 4k layer. That means both dm-crypt and the ext3 filesystem I intend to put it on have to do so also.
Looking through the cryptsetup document, it states under the option "--align-payload" the following:
"Align payload at a boundary of value 512-byte sectors. This option is relevant for luksFormat. If your block device lives on a RAID, it is useful to align the filesystem at full stripe boundaries so it can take advantage of the RAIDs geometry. See for instance the sunit and swidth options in the mkfs.xfs manual page. By default, the payload is aligned at an 8 sector (4096 byte) boundary."
The fact that the payload is aligned at 4096 seems to indicate to me that it should be fine using default settings. Does everybody agree with this? Or do I need to take special measures due to the dm-crypt headers?
When I later finish up the dm-crypt layer, then I need to put ext3 on it. I understand adding -b 4096 to the mkfs.ext3 command will resolve that. Is that also correct and will it work well in combination with the dm-crypt layer?

i have an external harddrive which i encrypted scince opensuse 10.2 with luks. Now i installed opensuse 11.2 its impossible to me to mount this drive correctly.
the harddrive was recocnized in my former opensuse 11.0 correctly as luks encrypted and during installation yast installed the kernel module and encrypted the harddrive so that i regulay could mount it on boot by giving the password for that harddrive. Scince opensuse 11.2 however yast thinks this is an dmcrypted partitoon and tries to unlock the harddrive using dmcrypt which of course fails.
does somebody know how i can encrypt and mount the externeal drive automaticly?
i have made a backup of /etc before i made a new installation of opensuse 11.2. is the possible to use the old fstab entries for that after installing luks?

I have gone through Mint, Ubuntu, Fedora, and continue using them on different PCs but I recently had a problem with my graphics card on new releases.. another story all together.So I am using OpenSUSE 11.3 on my Dell inspiron 1526 AMD 64 bit. I have always been able to plug in my external HD and have it show on my desktop. Now with OpenSUSE something is different. I tried other flash drives, all show up and open to view on their own, but my 1GB ext HD doesn't. I am not a pro with the Terminal yet but I prefer to use it and am good at reading and copying commands from online.

I'm trying to install Lunar Linux OS on my external HD alongside other OS's but only my fixed HD appears during the install process. I already have two Linux installations on the EHD. Is there a way around this problem or will Lunar only install to an IHD???

I'm very new to Ubuntu. Now that I have it installed, my computer doesn't recognize my external hard drive or flash drive. How do I access my external hard drive and flash drive? I'm also trying to get Rosetta Stone to work using Wine, but having a heck of a time. I've searched the forums and have found some similar topics, but nothing that really helped me.

Recently (in 2015) our Debian systems started not to recognize HDDs connected via an external docking station.
On my computer I run: (uname -a)
* Linux violin 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3~deb8u1 (2015-04-24) x86_64 GNU/Linux
* If I connect to a flashdrive to the USB2 port, it is recognized as sd* (messages are also written to dmesg/syslog)
* If I connect the USB3 connector of the external docking station with an 1TB WD SATA docked, to this USB2 port (the external docking station has its own power supply, so I do not expect to have a problem with the current, the drive spins up and is spinning), there is nothing in the dmesg/syslog, and no new items under /dev/sd* or lsusb or similar tools.
* If I connect the same external docking station with the same disk via eSATA on a different computer it is recognized. That computer runs the same debian. If I connect through its USB2 port it does not work either.
* I also tried another docking station and USB cable.

I am actually working again on a problem i had already on opensus 11.3 (never resolved), and now also after the upgrade to 11.4 .
I do have an external HDD (Samsung STORY Station) usually connected to the linux server. I also have udev rules setup to automount the device on /media/xxx by label.
I used to have my own rules, now have some more coplete from the internet.
When I now reboot the server, the "sd*" device for story station is not created, and obviously not mounted.
If however I do switch of th estory station after reboot, and turn power on again, the device is configured and properly automounted as by udev rules.
Also during the boot the device is seen as from boot.msg:
Code:
<6>[ 1.444939] usb 2-2: New USB device found, idVendor=04e8, idProduct=5f06
<6>[ 1.448686] usb 2-2: New USB device strings: Mfr=1, Product=11, SerialNum
ber=3
<6>[ 1.452462] usb 2-2: Product: Samsung STORY Station
<6>[ 1.456217] usb 2-2: Manufacturer: JMicron
P.S.: I used th esearch function and google, but did find many similar articles but nothing matching my scenario. So I hope I did not miss something obvious.

I have a Maxtor external storage HDD with firewire (1394) interface.
When I connected it with my computer, which is running an up-to-date Debian squeeze, it was recognized as "/dev/sda1" and replaced the existing partition on the computer.

OpenSUSE 11.2 server, Gigabyte GA-MA790X-UD4P sda for system, 3 ext4 partitions, working fine.sdb promise RAID1 for data, 1 ext4 partition, working fine.sdc is an eSATA docking station for data backup, 1 encrypted ext4 partition -- here lies the problem.
This configuration has been functional for months until I decided to add two more external drives (sdc) to rotate through backups. I had difficulty with encyption on the first new drive and eventually decided to start over. Using the gui Yast Expert Partitioner, I deleted the single partition. That began a real nightmare...
Since deleting the partition, the system detects drives inserted in the docking station, but does not report them (including a different fully functional drive and a brand new unused drive). I have tested all drives on other computers and they function perfectly. I have rebooted the system several times while troubleshooting this issue.
Could not recreate the partition on server (since it does not recognize the drive), so I used Gparted on another computer - it all went without a hitch, formatted ext4. But when I placed the drive in the dock, the drive still was detected but not recognized.
Details:
BIOS lists the eSATA drive
Entering Yast Expert Partitioner, error message follows:
The partitioning on disk /dev/sdc is not readable by the partitioning tool parted, which is used to change the partition table.
You can use the partitions on disk /dev/sdc as they are. You can format them and assign mount points to them, but you cannot add, edit, resize, or remove partitions from that disk with this tool.
Yast partitioner shows drives: sda, sda1, sda2, sda3, sdb, sdb1 sbc is not listed.
# fdisk sdc results in: Unable to open sdc
# dmesg | grep tail reports:
[48442.370779] sd 0:0:0:0: [sdc] Unhandled error code
[48442.370793] sd 0:0:0:0: [sdc] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
code....
So how did partition deletion cause this issue, and how do I correct the problem? It is possible that my difficulties encrypting the first new drive are related (it's not my first time doing it successfully). It seems the problem is in the Kernel or configuration. I have invested many hours in forums and on google - tried dozens of possible fixes. I'm beginning to suspect system corruption or a bug, however all other system functions are working perfectly.

The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.
[19712.013250] usb 2-2: new high speed USB device using ehci_hcd and address 21
[19712.145347] usb 2-2: configuration #1 chosen from 1 choice

I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.

I am running CentOS 5.5 and am trying to get Nagios to send out Emails.
After a bit of reading I have the following in my /etc/mail.rc file:
Code:
[root@linux ~]# cat /etc/mail.rc
set ask askcc append dot save crt
ignore Received Message-Id Resent-Message-Id Status Mail-From Return-Path Via
set smtp=172.29.1.76
You have new mail in /var/spool/mail/root
[root@linux ~]#
I have Nagios setup correctly and introduced an error to generate an Email but nothing has come through.I suppose I have two questions:
1. Is mail.rc setup correctly?
2. Can I test to see if mail.rc is working correctly?

I recently installed Kubuntu 9.04 Jaunty on my buddy's laptop. It's working alright, except when we try to plug the external computer speakers into the sound jack in the front, there is no change; it keeps playing through the onboard speakers. My friend and I are getting pretty frustrated because we use those speakers to watch movies with, and the onboard speakers aren't sufficient. If I need to provide any other info, let me know and I'll do so.

I just installed Ubuntu 11.04. The drive was formatted when I installed so it's 100% Ubuntu. The only major problem I have encountered is that Ubuntu will not recognize my SD cards. I really need to access these cards, all my film footage is on there. I think the internal SD card reader (If such a thing exists) would have been deleted during the installation process. I am a greenthumb to Ubuntu and have never used it before so I am rather stuck...

I have a backup HDD with a different distro for my laptop and i can boot into it via external usb or if swapped into the laptop. This HDD/install in question is debian testing and was working fine, the issue arose suddenly. I was first suspecting a failure of hardware somewhere on the motherboard, but the hdd i was using with an external usb adapter also works when installed into the machine. also, the HDD is recognized once i have booted using the external HDD and distro, but it is not recognized by the bios. so i dunno, my first guess is something became corrupt within the testing install, but i guess its also possible that there is some wrong with the HDD but thats not immediately apparent as all the data is still accessible.
Should also note that the HDD with testing on it is also recognized when connected via the external usb adapter, while booted from alternative distro/HDD.
Also. just tried this, but i can get the testing HDD/disto to boot if connected externally. it was going pretty quick, but there i did catch a line about a corrupt filesystem. any commands to run to see what might be going on?? log files to look at?

When I installed Wicd, and ran it for the first time, I got an error something like: "Could not connect to Wicd's dbus session- check the Wicd log file for more info". However, later when I restarted my computer, Wicd started, but I can't connect to my network, it shows up as <hidden>, I can connect to linksys, so I know that wireless is working on that computer. I know that there's nothing wrong with my wireless router, because I can connect to my network in this computer.

I work at a local computer shop as a computer technician and we get many computer in daily that require external virus scans (having to take out the hard drives, sticking it in another machine) just to scan (if we're lucky we can sometimes just do it in safe mode).Now what I want to know is...
1. Is it possible to install Ubuntu to an external HDD and use it virtually anywhere I plug it in? Will it pick up the network card, graphics card, etc so I can just plug and go? (Of course there are drivers for some computers).
2. Is it possible to run a Windows oriented virus scanner on Ubuntu? I know I can use WINE to run Windows applications, but will it prove to be compliant with virus scanners as well?
3. The main reason why I want it to be able to pick up on hardware and just work is because I plan on using it for schooling / travelling as well, have all my documents etc saved on it for easy access.
I've used Ubuntu in the past on an old laptop that didn't have much memory, small HDD, and a crap processor but that was 5-6 years ago (I still have the disk they sent me for free ).

I installed Ubuntu on external USB hard drive and while booting I did got option to log into windows XP, Ubuntu. Both operating systems ran fine. i.e. GRUB had overwritten MBR and I was able to dual boot. Main issue: I have installed Ubuntu in external hard-drive so that I can use Linux whenever I want other people who are using same computer can operate on WindowsXP. Sometimes my external hard drive gives problem if there is loose connection and so that oper people using computer do not face any problem I want to disconnect external USB HD whenever I am not using Linux. GRUB menu was pointing to external hardrive so disconnecting it meant my system wont boot!!I rewrote MBR using WindowsXP CD recovery mode. Now I am unable to boot from external USB hard disk( I thought I would be able to if I choose USB hard drive in BIOS option but it did not work it logged into WindowsXP by default).Is there any way I can change WindowsXP boot.ini file so that it also shows Ubuntu in external hard disk? Or is there any way.(I do not want GRUB way as then I would have to keep my external drive connected to log into windows - which I do not want).

I have an external hard drive with an xfs partition on it. It was using an external journal, but in re-installing Slackware I removed the partition holding the external journal, forgetting what it was at the time. I didn't touch the contents of the external hard drive, but now I can't mount it and the various xfs programs seem to demand that it be mounted in order for them to change anything.Anyone have any ideas on how to change an xfs partition from external log to internal? Failing that, how do I get the information off it?
