Ubuntu :: I/o Errors On Healthy Drive?
Mar 22, 2011
Whenever i do a cold startup (as opposed to a restart), i end up with a repeatable i/o error after roughly 5 minutes. This completely renders the system useless, and i'm talking to myself about raising elephants. I can _always_ restart right after the incident, and it _always_ starts up and i can use linux without incident for _days_.
What would do this? Is there a log i can peruse that might offer insight?
Also, this is a new sympton as of the last 2 kernel updates.
Actual solution:
See This launchpad bug. solution is about halfway down

Sometimes when I do anything write heavy such as transferring backup or downloading large files from the net, the machine crashes almost completely.

I am trying to backup my ~ directory to a portable drive. In the meantime rsync is giving me all kinds of messages like this:
[Code]...
This drive is neither plugged into my computer nor is it involved with my backup script:rsync $base_options -narv /home/noleks /media/Personal1/Linux_bak. I think the question is, does rsync have a queue somewhere of operations it did not complete? If so is there a way to rest this? It is possible something went awry with a previous sync on this drive but I cannot remember right now. Either way why is it trying to complete that sync when I'm asking it to do something else?

I am having problems with a cd/dvd drive and I would like to know if it could be a driver problem or what?
I can boot from cdroms but I almost always have problems mounting the cdrom's filesystem.
The laptop has been working for years with the same ubuntu release (hardy) but there are always a couple of warnings during boot time saying that certain drivers should be updated but I don't know how.
These are the persistent messages from dmesg output:
Code:
[ 12.693449] Driver 'sd' needs updating - please use bus_type methods
[ 12.700371] sd 0:0:0:0: [sda] 156301488 512-byte hardware sectors (80026 MB)
[ 12.708884] sd 0:0:0:0: [sda] Write Protect is off
[ 12.715663] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00
[Code]...

Someone explain this to me. I often thought in the back of my head, how do I check if my drive is bad in Linux? I always excused it thinking well I guess besides gaming that's another reason to keep a windows partition around. I boot up yesterday and Gnome was acting weird. Then, it happened. "We have detected bad sectors in your hard drive." I thought, no, you're stupid, this hard drive is less than a year old (however it was a replacement for another one that died). So I reboot.
Boot back up - Different error message. But instead of getting it a few minutes after log in, I got it right away. "We have detected potential hard drive failure." Okay, Linux. Want to play this game? Booted to Vista, downloaded Seatools to test my Seagate drive. It failed... Swapped SATA cables... it failed... So I ask - how does Linux have this auto detect capability like that? As much as I love Ubuntu, I was like there's no way it could just magically tell like that without running the Seagate program. But alas, Ubuntu was dead on target.

I have a laptop, running Windows Media Centre unfortunately, and I think the hard drive is hosed. I was wondering is there away of checking the hard drive for errors using the ubuntu livecd? I would put ubuntu straight onto it only there are various items within Windows that the owner needs to get.

i am currently running palimpsest (system -> administration -> disk utility) and letting it "check" an unmounted filesystem.
i know its just running fsck.ext3 on this drive... the drive is formatted ext3, and is used on a hardware media player (WDTV Live Plus) in another room... i just moved it in here to avoid copying recorded HD shows over the LAN.
anyway, i was informed at boot with this drive connected that it needed to be checked, after booting it is mounted, but says it has errors and needs to be checked. it is checking, i would assume messages from fsck.ext3 would be logged to /var/log/fsck/checkfs, but i have never been interested in this type of thing before... usually when my drives start to get errors, its time to replace them... this one im sure is caused by being unmounted incorrectly by the stupid WDTV Live Plus...it locks up sometimes, lol...
i dunno, this is a big drive. just wish there was some "status update" other than a whirling indicator... im tailing the log file i mentioned above, but so far it just has "Nothing has been logged yet." (which i take as a really good thing at this point.
EDIT: at the very end of the filesystem check, i got a message about the filesystem being clean with no errors. id still like more of an indication than "whirling indicator thingy"...guess ill go back to CLI for checking filesystems. lol

I have a Dell Dimension 690 with a LSI raid controller. I just added two 2Tb drives to the 2 160Gb drives that I currently have. The 160Gb drives used to be set up in a redundant raid configuration and are now set up as stand alone drives. The 2Tb drives are redundant raid. I installed Zentyal server software (formally eBox). It seems that the system is starting up OK but on booting I am getting the following errors:
[Code]....
I do not want to put data files back on the server if it has some errors that will bite me later.

I have been running 10.4 with no problems for some time now. Today when I booted up it started checking the drive for errors, and I just left it to do its thing. I came back to this warning screen: Ubuntu is running in low-graphics mode.Your screen, graphics card, and input device settings could not be detected correctly.
I've tried all of these with no luck. When I select to run to low graphics mode, it says "Stand by one minute while the display restarts...OK".I select OK and then it gets stuck checking for battery state.I try to reconfigure the graphics, and nothing happens when I select any of the options on the next screen.

anyone shed some light into these errors I keep getting for multiple files when I run rsync in verbose mode to a FAT32 external hard drive?
rsync: stat "/mnt/usbdrive/Batch 2/od venezuelan" failed: No such file or directory (2)
rsync: recv_generator: mkdir "/mnt/usbdrive/Batch 2/joseph gangster" failed: No space left on device (28)
I have 588GB available on my external hard drive, and i'm only trying to rsync 200GB to it, so its not out of space or anything like that. I've tried rsync with -r -t --size-only --delete and -r -t --modify-window=1 --delete and both ways seem to give me the message. or should i just reformat as NFTS and start over? i already had another 200GB data set copied on here, was trying to add a second. its all JPG pictures.

I just bought a new hard drive for my lenovo ThinkPad R60e. It is the following model:
Code:
# hdparm -I
ATA device, with non-removable media
Model Number: WDC WD5000BUDT-63G8FY0
Firmware Revision: 01.01A01
[Code].....
After scanning selected spans, do NOT read-scan remainder of disk. If Selective self-test is pending on power-up, resume after 0 minute delay.
It is regardless which kernel version I use (latest ARCH Linux 2.6.39 or 2.6.23 from a grml live system), the error is persistent everywhere.

I am constantly replacing server drives at work. Our terminals use Transcend 2gb Compact Flash Drives. Sometimes we run into drives that need to be replaced due to IO errors. Which brings me to my questions.
I have heard that you cannot restore data from a drive that has IO errors. Is this true with Compact Flash Drives? It is to my understanding that IO errors are due to bad sectors on a harddrive and not the file it self. Is this true? Why can I not use the old drive to restore from?
My process is to mount the Old Server as dev/hdb and the new server as /dev/hda. Then restore the customers data. Every server card already has our software on it. We are just restoring sales info and that stores specific data.

I installed Ubuntu 10.10 beta yesterday and most of it is working very well. However, I ran into a problem with permissions today.I have a HDD containing my home folder and a HDD containing my data folder. The HDD with the data folder is mounted on /media/data/data_1.
Code:
jensen@jensen-desktop:~$ ll /media/data/ | grep data_1
drwxrwxrwx 8 jensen jensen 4.0K 2010-09-07 23:10 data_1/[code]....
I made sure I had set a+x rights on the file, tried executing it as root but the permission error stayed.When I copy that same file to my Desktop folder I can perfectly execute it.When it's located on the other hard drive I can't. I tried several command line scripts and they all work when I execute them from my OS hard drive,but not from another hard drive.

I'm trying to create a dual-boot system, and have been following the instructions here. However my hard disk has bad sectors, and GParted won't let me resize the Windows partition. It tells me to use ntfsresize with --bad-sectors as an option, after having done some checks, all of which I've done. I've successfully shrunk the NTFS volume in this way -
when I boot into Windows, it says the hard drive is the size I set it at. However, the Ubuntu installer and Gparted still see the Windows partition taking up the entire hard drive. So, for the installation, do I have to set the size of the volumes manually, or is there a way to make Ubuntu see what ntfsresize has done?

I just upgraded to Fedora 11. (I decided to give 64bit a try and I am extremely impressed.Not one problem at all! Kudos to the devs.) Whenever I log in I get the Palimpsest Disk Utility telling me two of my hard drives have a reallocated sector count.I have two 1.5Tb Seagate drives (model #: ST31500341AS). One is a backup of the other. On the first disk the disk utility tells me I have 22 reallocated sectors and 53 on the second. I've been on Google on discovered that there is no easy way to fix this and that a few bad sectors are okay but too many is a sign of imminent drive failure. This obviously concerns me because both my main drive and its backup are showing errors.
I went to Seagate's website and downloaded their diagnostic software (Seatools for DOS) and it passed both of these drives.So, questions: is it possible that Fedora is giving me a false positive? If not, is 22 and 53 sectors something to be concerned about? If so, should I contact Seagate and see if I can pull warranty on these drives? Is there a way to repair this damage?

I had a set of rather unusual problems on installing a new 500Gb hard drive on my F14 system, I've solved them, but they were that unusual that I thought I should share them in case anyone else gets the same thing! I'd been experiencing intermittent faults on one of my drives, (lock ups for no reason, occasional boot ups that failed due to ' disk unreadable errors' and other odd errors). I assumed that the drive was failing, but it always showed 'Heathy' on disk utility! This was the disk with the OS on, plus my main 'data' disk had some bad sectors, so I thought I'd buy a nice big 500Gb and reinstall the whole system.
I backed up all my data to an external 'USB' drive, opened the case, (a big old under the table 'desktop', why do they still call them 'desktops'?) shoved in the new SATA drive and rebooted, intending to format the new drive to EXT4 and partitioning it before installing F14 again! OOOOOOOOOW! Major drive failure, missing OS, whole list of SDB errors! Control D, to reboot, BIOS only sees one drive; SDA (I have three, two IDE and one SATA) plus the one I just put in makes four. I go into BIOS and discover that it not only cant see any of the other drives, but my two DVD drives are missing too!
Now I've been building my own systems and mucking about with computers since before you could buy them, and Ive never seen a problem like this one! At first I thought the new drive had screwed my system, for on removal, the problem persisted! Then I noticed that the IDE connector in drive SDB, (the long 40 pin job) was just slightly out of line with the back of the drive, pushed it firmly in and what do you know, everything works! We moved recently and I think the vibration was enough to loosen the connector to give intermittent faults, and pulling the cables about to get the new drive in, pulled it out further......

I recently got a computer donated to me for free from my Computer Science class, as the teacher couldn't figure out what the problem was that was preventing him from booting to the startup screen (all I could figure out was that the slot the memory card was in was bad, so I switched slots and got it working). The hard drive on the computer was wiped with a disk nuker called DBAN. Now I would like to install a Linux OS on the computer, but whatever disc or distro I try gives me similar "unable to read" errors. I would like to know if there's anything software-wise I need to do before attempting to replace any hardware. An example of the error I'm getting is as follows (using a mandriva livecd):
/etc/rc.d/rc.sysinit: line 1281: /var/log/dmesy: Read-only file system
SQUASHFS error: sb_bread failed reading block 0xa6e58
SQUASHFS error: unable to read cache block [29b963ea:782]
SQUASHFS error: unable to read directory block [29b963ea:782]
Anyone know what I need to do to get this fixed so that I can install a Linux distro?

I am getting a new 4kb sector HDD for my laptop, WD scorpio black 750gb, I would like to image existing partitions on 512bytes sector HDD and move them to the new 4kb sector HDD, what's the best way to do this.
present config is as follows:
Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code].....
I am planning to keep the same three partitions as the primary partitions on the new drive and add few more logical partitions. I would have liked to move to GPT but since I need Win 7, I am stuck with MBR partiotion table.
Now, I understand how to partition an Advanced format disk, what I want to know is how to move the existing partitions on the 80 Gb disk to the new disk?
I use Clonezilla to copy partitions but it is not compatible unless both the target and the source disks are already using 4096 sector size.
I can use Acronis True Image WD Edition to clone Win 7 but how do I clone Ubuntu?
Also my Laptop's chipset is limited to SATA 1.5, will it cause any issues, I know the bandwidth is not an issue.

So I install Ubuntu 10.10 on a multi-drive, dual boot with windows 7 computer. At almost the end of the install, I see "running grub-install sda" or whatever it is. sda is my windows drive.So rather than asking where to install the bootloader or give you the option like it used to, it just did it to my "first" drive.
What the hell? Now my Windows MBR is gone. I like to maintain that so if my linux drive dies I can still boot into windows via the old windows boot loader.Possible to move Grub2 to my other drive and repair windows 7 drive MBR?

I recently scapped XP Pro on an old laptop (Toshiba Portege 7220)as it was so slow and I installed Ubuntu 9.10 - All installed ok and it worked fine for about a month. Last week I switched on, got the Ubuntu splash screen and thats where it stayed. I gave lappy to a friend of mine that knows about Pc's (hahaha). When I got it back he said he'd wiped the HDD and partially installed xp. The install apparantly hung after the reformat and copying files onto it.My problem now is I can't boot from HDD, Ubuntu Live CD or Windows CD - Laptop is set to boot from cd then hdd.When I try to boot from CD, the cd is read as I hear the drive being used also see light for cd flashing, after a while i get a blank screen with flashing cursor in top left corner and the cd stops.If I remove the HDD and put it in external usb caddy I can see the windows folders/files when plugged into my desk top.My questions are :-
1. Is there any way to make the drive reusable as a internal drive again as I know it works as an external drive.I would like to reinstall Ubuntu on it
2. Is it a fault with the laptop itself - how do I check

I was trying to figure out how to get my network drive to mount as a local drive on my computer. This was back on 9.10. Since I've upgraded to 10.04, my boot process halts and tells me (paraphrasing) /shared is not ready to mount. To continue, pres S to skip or M to manually mount the drive.
Well, I have it mounting now through GVFS and I don't need this in my startup anymore. Frankly, it's just annoying that it won't boot into Ubuntu right away. So, what's the startup file I need to edit to remove the attempt to mount the network drive?
