since i've installed lucid, when booting up between the splash screen and the desktop i get lines of multiple i/0 errors. i checked disk utility and it's reporting multiple bad sectors on my hard drive
i don't think that the lucid install is the culprit but since i have no idea i was curious if anyone thinks it's related. not worried about the hard drive, i have a back up formatted and ready to go if this one goes nuclear.
I did set up a new server (with mail, apache and lots of other stuff) and was not aware that the new harddisks of type WD10EARS-00Y5B1 were using 4KB sectors internally. The problem became visible after going live because of the lousy performance of the harddisk drives.
Present situation: openSUSE 11.2 i586, 4 GB RAM, 2x 1TB HDD
Code:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

I already did re-partition /dev/sdb with parted-2.2 (compiled from source) and set the alignment starting with sector 64 (instead of the default 63) making sure that the sector count of every partition divides by 8. Now comes the tricky part: I must partition /dev/sda as well. I can backup everything to /dev/sdb. What is the recommended course of action here? Make sdb active and boot it? That would give me all the time I need to deal with sda. Then reverse again. Any backup of /dev/sda will be outdated soon (running system)Rescue DVD only offers parted-1.9.0
I created a customized Lucid image and installed on my computer which has 1 hard drive (/dev/sda)When I booted up .. it gave me an error indicating "Multiple active partitions" ... and did not boot up ...
I used my live CD and run as live session to check on the hard drive, When I issued the command fdisk -l on an terminal , the out put indicated that only /dev/sda1 is bootable, and other /dev/sda* were not bootable ...
I am not sure why I got the "Multiple active partitions" message at boot up time ..
I have an harddisk which is old, since many years >10 years, and I recall I crashed few clusters using windows programs which were old and harddisk stuffs doing. So the pc lives with bad clusters, this pc lives very well since many years.Question, the pc has woody debian, which let us to install and exclude bad sectors during install. Bad clusters was an usual thing in the past, but today not anymore.Unfortunately debian squeeze installer coders had the good idea to remove the " bad cluster checking " before installing debian, during install (cdrom netinst).

View 1 Replies View RelatedI used to have windows xp. But recently I started having a message at startup telling me that my disk might be failing and I should run the test (which would crash and reboot th laptop). Then after a while windows wont even start. So I tried to use ubuntu netbook live from a usb and it is working fine ! I can even access all my data on the hard disk, although it is telling me that the hard disk is failing and that it has 1024 bad sectors. I have only one hard disk and one partition (120 GB). Can I just install ubuntu and somehow block the bad sectors? (I don't want windows anymore) and is there any way I could keep my old data on the hard disk without backing it up (it is not really important btw).

View 4 Replies View RelatedI have some errors on my drive and I fear it may be faulty. However there are a few things I would like to try before replacing it through the manufacture or buying a new drive of my own seeing as this is a brand new computer.
Here is my computer and drive:
Acer 5251-1513 Laptop
Toshiba MK2565GSX
Running Fedora 13...now
Here is what is going on. Tried several version of Ubuntu 10.4 (studio, 64bit, 32 bit) and was having many errors during startup and having to press F to fix. Then I lost something with Gnome and the GUI would not function, and I did not know how to replace it. Tried a few other distros but could not get them to work (mostly on my part I am sure.) Then after some forum talk, thought it might just be Ubuntu unable to handle my drive. Now on Fedora 13 and a warning comes up every time I startup. "Disk has many bad sectors"
In the disk utility under the SMART Data it has 2 of the following warnings:
5- Reallocated Sector count..with a value of 72 sectors
197 Current Pending Sector count...with a value of 35 sectors
Total Bad Sectors 108.

I have used Fsck several times through a live CD, but the problem persists. Trying to understand bad blocks and how to write them to a file?
I have an Acer tiny desktop using laptop components and I want to replace its small laptop hdd running Vista with a Kingston SSDNow V Series Boot Drive 30GB and install Ubuntu, since it will support TRIM. I am aware of the current issues on some new hard drives with 512 vs. 4k sector sizes and the necessity to align sectors for those drives. And I know I've seen some posts or discussion of aligning sectors for SSD's.
I'll be doing more searching for info on this, but my previous searches on the 4K sector alignment issue for the new WD hdd's on linux were confusing. Does anyone have definitive information on the necessity of aligning 4k sectors on current Linux kernels, or on whether aligning sectors is necessary for SSD's?
A hard disk occasionally fails. Standard checks like fsck and scandisk fail to report any problem. Is there other software to exercise the disk much more thoroughly so that bad sectors have no chance of being missed?

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.
I have a massive ZFS array on my fileserver. Whenever a disk reports bad sectors to smartmon, I order a replacement, and I shelve the failing one.
And by "shelving the failing one", I mean that I give it a low-level format if applicable, or a destructive badblocks run to possible claim spare sectors to replace the bad ones, then use it to dump my DVDs (and lately BluRays) on, so that I can use it with my HTPC and bring it with me when going to my friends to watch movies. It's just a really easy and portable way to watch movies with XBMC. I have the stuff on pressed discs already, so I'm not dependent on their reliance, and the dying drive just gets a hospice life serving as quick-access media storage. Keeping in mind Google's reports that drives are 39x more likely to die within 60 days after their first SMART error, I'm expanding that period by the fact that these drives mostly remain on their shelves and are only plugged into the SATA bay once or twice every year.
I'm just saying this to make clear that I'm not confused about these drives dying, and I'm not looking to elongate their lives ;)
So. Sometimes these drives, after a badblocks run, simply claim fresh sectors from the spare pool, but sometimes there aren't any left, and I face the fact that there are bad sectors in my FS. That's not a problem if you use one of a set of linux filesystems, as mkfs.* often takes a badblocks list as input. But seeing as I sometimes bring a drive or two to my girlfriend's (Mac) or one of my friends (usually Windows), I've decided to use NTFS for these things. Up untill now, when a drive had unrelocatable bad sectors, I've just written data to it, re-read it, and files that were bad were put in a "BAD_SECTOR_FILES" folder on the drive.
Sure, it works, but it would be really nice to be able to just mark those sectors bad instead. It's a lot of hassle the other way around.
So I read some posts, of which most quickly switch subject to the often accurate one of "replace your drive!", and some suggest spinrite, but really, I don't see why I should pay that much money for such a trivial task.
The alternative is to use ext3, but I'd like to hear if someone knows how I can feed badblocks output to mkfs.ntfs, so that the bad blocks aren't used. Or if there are other tools (I could use Windows in a VM) that do the same. I'm confused about chkdsk, it seems the bad sectors thing is FAT only?
Just came up my mind about repairing the bad sectors using software.Does using a software really repair the bad sectors in the hard disk?
View 5 Replies View RelatedMy sister's laptop (toshiba satellite l550 running lucid) often runs really, really slow, even after a fresh install. Going through the gnome main menu, everything just lags by several seconds. Closing applications often takes a while, etc. I've run top and iostat to determine what the problem is and it seems to be IO-related. User processes and system processes don't take up more than a few percent, but the average load is usually over 2 even when I'm barely doing anything. Top shows that, whenever everything slows down, the 'wait' criterion is pretty high.
Now, I've also tried installing lucid to an external USB hard drive and that works fine. I'm currently running the S.M.A.R.T. diagnostic and so far I've got the attached screenshot to show. Only the criterion shown and the 'current pending sector count' are showing warnings.Any thoughts? Could the performance issue be related to the hard drive warning? I'm not planning to replace the hard drive just yet, because this laptop still has a two-year warranty.
I've just added a second disk to one of my computers. It is a 500GB SATA. It is the second drive according to the BIOS. Fedora calls it /dev/sdb. So far so good. This box is running Fedora 13 final. Never any problems until the addition of the new disk. Palimpsest says that this disk has a LOT of bad sectors. This disk is a storage drive. I want to address the problem but don't know what to do first. My thought is to rsync all the data to my external 250GB disk bedore I do anything else but I'm mot sure if I should just yet. Maybe I should run some diagnostics on the drive? If so, what? How about the tools Disk Utility offers? Should I use the Smart Utilities? What other Linux tools are available and are they reliable? Maybe I should install XP on the main disk and use Windows' disk tools? If I should lose all data it wouldn't be the end of the world but I'm not sure how "in sync" the 2 storage drives actually are.

I can't seem to find any programs or applications for linux that will find bad sectors of a usb drive. I have seen plenty for Windows, but I was wondering if there are any for linux.

View 2 Replies View RelatedI'm kind of new to programming in Linux & c/c++. I'm currently writing a FileManager using Ubuntu Linux(10.10) for Learning Purposes. I've got started on this project by creating a loopback device to be used as my virtual hard disk. After creating the loop back hard disk and mounting it has the following configuration.
Code: $> sudo fdisk -l /dev/loop0
Disk /dev/loop0: 10 MB, 10977280 bytes
255 heads, 63 sectors/track, 1 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: 0x00000000
Disk /dev/loop0 doesn't contain a valid partition table Now what I want to do is develop a c++ program to read & write files to this loop back device,which I'm using to simulate an actual hard disk,at the blocks & sectors level. So far I've come up with the following code. But I'm still unable to read files from the hard disk one block at a time.
Code: #include <iostream>
#include <stdio.h>
using namespace std;
int main() {
char block[512]; int length=0;
cout<<"Implementation of the File Handler Read Method..."<<endl;
FILE *f = fopen("/dev/loop0", "r");
if(f == NULL) {
cout<<"Error In Opening the HardDisk File Retuning Error..."<<endl; return -1; }
//Read One Block of Data to Buffer length = fread(block, 1, sizeof(block), f);
/* Do something with the data */ cout<<"Length : "<<length<<endl;
return 0; }
When I run this Program All what I get is the message for NULL. "Error In Opening the HardDisk File Retuning Error...". So I could open the loopback device as a file an access it at the sectors & block level.
I am running Wheezy 7.9 (32 bit) and using Gnome Classic desktop. I have recently had several issues with system "crashes" and such, see some of my recent posts, and for now things seem to be working okay. As part of my attempts to "fix" the problems I looked at the hard drive using the SMART disk utility, and also ran "smartctl". The SMART utility reports that there are 3 bad sectors on the drive. When I run fsck, from a live CD, it does not report finding bad sectors. So why would fsck not find something that is reported by smartctl? Which one should I believe?
As a precaution I am now making daily backups of my /home directory and purchased a new HD just in case. Have not yet installed the new HD but at least I am prepared.
Can someone point out such a program?

If I know the USB device number, like from 'lsusb', is there someplace on the system to get other information about the drive? What I want to do is have a program go out and get this information just for the number of LBAs on the drive itself. Partition info doesn't matter for what I am doing.

To my understanding, this means that the disk is beginning to fail, and should be replaced..
Short story..I have about 35.000 images on these disks... (shared on network, as a samba share with PCs using Picasa) I've doing backup to 2 separate USB disk, and sometimes I connect a third usb disk and transfer to this aswell. I'm worried now that "some" of my image/data might have been lost - due to the 2 lines above. (checking if something is missing, of the 35.000 images is not easy.. and I have not made any txt file with all files/names/size og the images -...I see now that I also should create such a list, and not just take backup)
How critical is this "Offline uncorrectable sectors" and how can I check/do something about it ?
I was running a 2-partition hard drive, Windows Vista (lamentably) on one partition, and the other running Ubuntu. I began having trouble with the Vista partition, so I attempted to move as many of the files that I really wanted to keep as possible over to the Ubuntu partition, and then reformat and reinstall the Vista partition. As a result, I could no longer boot to Ubuntu, and I consistently got errors back from everything that I tried on the Vista partition.
The only way that I can now access anything on the hard drive is to insert the Ubuntu install disk, go into trial mode, then mount the partition. At long last, here is the problem: Is there anyway to possibly make the partition bootable again so that I could burn the files to a disk? From trial mode I can get to a number of the files on the mounted partition, HOWEVER, they are secured with the username and password of my user account on that partition. Is there any way that I can access the files from the trial mode by entering my username/password?
I have a 230GB hard drive wich I don't know it's name.I have a 207GB windows vista partition and the rest of it is for linux (Ubuntu).Today I decided giving it all space to Ubuntu Linux ,but didn't want to lose all my data from the windows partition.I thought that by deleting all things except the folder with my data and leaving enough space to shrink and make enough room for another partition to put my data folder.The logic is that i could then format that partition wich previously was windows and use it all for ubuntu without losing data.After having ubuntu installed i could copy my data folder to /home and then delete the previous partition and make /home bigger.The problem is that after i freed the space,when using Gparted to shrink it says that the partition has bad sectors or the filesystem has problems and so it can't do some operations.
What could have went wrong?It told me to do chkdisk but as i deleted all the windows files and i can't boot into it anymore.I used the vista dvd to do that.I rebooted 2 times as it says and after that when trying again nothing changed.I tried to use ntfsresize with the --bad-sectors argument and also the -f argument but it's useless.At the end it says it won't do anything until the ntfs filesystem get repaired.Or it says it is too risky to continueIs there any way i could do some superforce command to resize it without losing data?Please don't tell me to put it on an external storage cause i have like 70GB of datas to save...no i don't have an external hardrive
