Ubuntu :: Cd/dvd Drive Not Recognized After 9.10 Install?
Mar 1, 2010
I recently upgraded from 9.04 to 9.10 and now my cd/dvd-r drive doesn't exist. When I run sudo lshw -c disk command I get
*-disk
description: ATA Disk
product: WDC WD1600AAJB-5
vendor: Western Digital
physical id: 0
bus info: scsi@0:0.0.0
logical name: /dev/sda
[Code]...
It shows all my drives (including the little usb flash drive) but I can't get to the drives from "computer" all it shows is cdrom0 floppy0 and filesystem

I am running Ubuntu 10.04.03 on an ASUS P5VD2-X. There are numerous HDD attached, but one is uniquely Win XP, the other uniquely Ubuntu. Boot choice is via a GRUB loader. Ubuntu is the first choice normally. The problem is that more often than not, the system does not seem to be able to recognise the CD or DVD reader/writer. On some random occasions, they are recognised, but mostly not. But - and here is the upsetting bit - this problem never occurs when I boot up on Win XP. The CD/DVD devices are instantly and reliably recognised each and every time. So I guess that rules out a hardware or BIOS problem. This is a particularly annoying problem as use of the optical drives is required frequently, and it galls me having to revert to Windows just to use them.

I have a 2nd hard drive (500 GB) that I keep my media on. When I tried to access it, it wasn't showing up in places or even places > computer. I used system > administration > disk utility. On the left hand side it shows the drive listed with the type and model number. Right under that it shows 500 GB Hard Drive unrecognized unknown or unused. If possible I would like to recover the media on this drive. I had setup this drive as ext3 and had it mount /media/sdb1. I can go to /media/sdb1 in the file browser but nothing is there.

External USB 3 drive not recognized after upgrade to Natty. Works fine and is recognized immediately when plugged into USB 2. Occasionally the drive is recognized with USB 3 when plugged/unplugged. Worked fine in Maverick (with USB 3)

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?

I am trying to install this OS. However no matter what I do the UBUNTU instllation CD doesn't recognize the hard drive on which I would like to install the OS on.
I currently have two SATA hard drives connected to my computer. MY primary is my Windows 7 drive and my second hard drive is my spare.
When i load up UBUNTU and get to the window where I can select which hard drive/partition to install to my second spare drive isn't there.

rEFIt can not see my USB thumb drive during boot, therefore can't install. Tried using the dd utility to copy the Ubuntu ISO to a spare partition on my internal hard drive. Now, rEFIt sees that drive but attempting to boot into it gives me a 'Missing Operating System' message. So I'm back at trying to get the system to boot from the pendrive.

I recently did a fresh Maverick install on my old Medion laptop (MD 42200), and a problem occurred.
The problem is that the CDROM-drive is not recognized by Ubuntu. There is no icon on the desktop when I insert a disc, and I can̈́'t find it in either /media, /cdrom or /dev.
I can see it in the standard Disc Tool program, where it is listed as being located in /dev/sr0, and it is visible in a downloaded Device Manager.
What can I do to access my CDs?

Trying to install Fedora 12 using the 6 CDs. Trying to install on an older x86 box.Problem is that when detecting my hard drive, Fedora 12 recognizes it as a sda hard drive instead of hda hard drive. I have no SCSI connected to my computer what so ever. It's an old fashion PATA Western Digital hard drive.If I proceed with the install, Fedora 12 only installs 200MB of the OS from the first CD only. No options for additional software or anything.

I am trying to run You Don't Know Jack in wine - appdb says it has Platinum status, so compatibility shouldn't be the issue. My laptop doesn't have an optical disk drive. So, I ripped the disk to an iso image, mounted it with gmount-iso, and tried to open the program.
The program still says the disk is not inserted. I know on previous laptops with optical drives, I could mount an image on /dev/cdrom0 or /dev/sr0 or whatever and it would be recognized. My /dev directory had no cdrom0 directory, so I made one. I mounted the iso there but it still didn't recognize it. I've tried in my home folder, in /cdrom, and in my newly-created /dev/cdrom0 but no luck.

So my World Book Network Drive stopped working all of a sudden and I decided to remove it from the enclosure and plug it in via USB. I can see it in Disk Utility, I took a snapshot of it and attached it here. Normally when I plug a hard disk into ubuntu you can see it in places, not the case with this one. I would like to try and retrieve the data from it?

I have a weird problem with an sata partition. This drive is onle volume of an md raid set, and has one partition filling the whole drive. of type "fd" ( linux raid autodetect). When my machine boots, the drive containing this partition is present as /dev/sdc. However, the partition is not - there is no /dev/sdc1. If I look at the partition table in fdisk, all appears to be fine. If I do anything that causes the partition table to be rescanned (such as writing in fdisk, or running partprobe, ... ), the partition shows up fine at that point and all data is present and when I assemble the RAID using it, its in sync. This drive is attached to the same (motherboard) controller as my other drives which have their partitions recognized just fine.

I'm running Ubuntu 10.04, and am having trouble getting it to recognize my flash drive in the USB port. It showed up once in the Computer - File Browser and I was able to mount it and access the files on it, but since then it doesn't show up. It works fine on my Ubuntu 9.10 distro. I get the same results on both distos when I run #lsusb# The results are:
Code: Bus 001 Device 002: ID 05dc:a701 Lexar Media, Inc. JumpDrive FireFly
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
I can access the flash drive?

I just installed centos 5 on a hp dl380 server and it has 2 72.8 scsi gig hard drives. The problem I am having is that only one hard drive is being recognized and it is not being recognized as a scsi. This is what I get from fdisk -l
Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes
255 heads, 63 sectors/track, 8854 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p2 14 8854 71015332+ 8e Linux LVM
as you can see, the system doesn't even see the second hard drive. How do I get both hard drives to be seen and how do I get them to be recognized as scsi?

With CentOS-5.5, centos plus enabled, my LaCie external hard drives are not recognized even though connected and powered up before booting. I am logging in as root. Previous 2.4 kernel RHEL Enterprise 3 required a special scanning script which worked with this computer. This current system will not recognize the drives as hardware. On the other hand the drives with USB 2.0 ports automount connected with USB and also are recognized in the hardware list. what diagnostics to do to find out what layers / drivers are missing.

I am trying to install ubuntu 9.10 on an system which already has XP installed. I had used Ubuntu earlier but when I installed XP ( in an attempt to dual boot) I seem to have lost the Ubuntu Installation. But the problem is GParted or the Ubuntu installer dont recognize the existing partitions but instead see it as an empty unallocated drive. I have a 120GB hard disk. Below is the extract after fdisk:
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4fa8a60b
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4fa8a60b .....
Also this is how the disk Utility in Ubuntu sees my system: ( See attachment)

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.

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.

As per documentation, only NETWORK install is supported if the guest is to be installed as paravirtalized.I copied the CentOS DVD in /home directory with folder name centos52 and exported it through NFS. When I run Virtual machine manager and give installation path as: nfs:<ip address of host>:/home/centos52 , the system while trying to create the storage fails and throws following error:Unable to complete install: 'Invalid install location: Mounting location nfs://<ip address of host>:/home/centos52 failed'
