Fedora :: Overheating And Bad Hard Drive - Warning "reallocated Sector Count"
Aug 3, 2009
Upon installing Fedora on my Samsung NC10, I loved it. It feels stable and isn't cluttered with pointless apps. However I was immediately greeted by Palimsest Disk Utility warning me that the 'reallocated sector count' on my hard drive is going bad. I'm not too sure what any of it means but here's the statistics;
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 have WD external hdd (80GB) formatted with fat32. I was using this hdd to transfer the data from computer A (LINUX, RH9) to computer B (Win7).
I was keep copying and deleting the data in the WD hdd during the data transfer because the amount to transfer is more than 300GB.
After doing this several times (and the WD drive was emptied), comp. A said the disk is full. I checked using 'df' and it was really full but 'ls -la' shows that there is no data in it.
I checked it in comp. B, and it showed empty. I tried to format in comp. A using 'mkdosfs -F 32 /dev/xxx# (block#)', but showed an error message like below.
'Warning: block count mismatch: found 78xxxxx but assuming 0'.
I found a similar situation in this forum metioning 'possible damaged linux kernel (not exactly same expression though)', so I re-installed linux in comp. A, but the problem was not solved.
1. why the disk info. is showed differently in linux and win7 2. why I cannot format it
After some time (thirty second - a few minutes) computer hung (screen froze, I couldn't switch to console, only hard reset helped). From log message I suspected graphic card and I replaced it to some other based on PCI Express (GeForce 6200). It's better. Computer works fine during office work (OO, Firefox, ...), but after being a few minutes in 3D mode (e.g. game with graphics 3D) hangs in the same way.
It all started about a week after upgrading to Jessie and I had an unusual system failure, in that the CPU went to 100% usage and the hard drive light was on constantly. The keyboard and mouse were were non-responsive. Not having REISUB enabled I did the "stupid" thing and pushed the reset button on the computer. BAD BOY! As a result the computer would not boot and I had to use a live CD to format the drive and install Wheezy (I had the CD).
After installing Wheezy, everything worked well for about 3 days and then it did the same thing. Fortunately I had REISUB enabled and was able to reboot. I looked at the syslog and found a segfault with colord-sane and, after some research that suggested colord-sane might be a problem, I set UseSane=1 in colord.conf . Things seemed to be okay for about 4 days.
Well, after all that I had another problem today with booting. During boot I got an error message saying that there was some hard drive problem and that I needed to log in and run fsck, which I did . There were I believe 4 INODE errors that I was asked if I wanted to repair, to which I responded yes. After that the system booted correctly. After booting and entering the Gnome Classic desktop I looked at the Disk Utility and checked the SMART data. There is now 1 bad sector where before there were none. The drive is a one year old WD 500GB Velociraptor.
Don't know if this is relevant, but in the days before this latest "crash" I had downloaded about 8 movies using bittorrent. Could this have overtaxed the HDD?
I guess my questions are: When fsck "repaired" the disk would it have moved any data from the bad sector to a new location? What may have caused the sector to go bad ? Should I be buying a new hard drive?
The system seems to boot okay,at this time, so I assume that no critical system files were affected. Just curious as to how I should proceed. First is BACK UP my data. Got that !
One more thing I just thought of is that every time it "crashed", I was using LXDE.
I was testing out Ubuntu 10.04 on both the a desktop and a laptop (both HP...I don't remember the particular models but if asked I will find out). It worked fine on the desktop. When I booted the laptop with Ubuntu it worked fine. When I tried to connect it to the internet it seemed to go okay. I mean it asked for the network password and everything. But as soon as the signal was recognized I got a warning that said "Hard drive failure is imminent."
Now this laptop has gone through problems before. I don't know the extents because it's a family laptop and I rarely use it (it's super slow. It used to run Vista but now it runs XP and it's slow regardless). I think the hard drive may have been replaced at one point of another and it has had to be re installed numerous times before. And the way it is used leads me to believe that there is not a lot of space left in that hard drive. So that may have been the issue.
But I want to make sure it is a hardware problem and not something that will happen on the device I eventually decide to install Ubuntu on. How to understand why the hard drive would fail when the live CD doesn't actively use the hard drive, at least not the way it would if it had been installed in the hard drive.
I am trying to install Ubuntu to an external usb hard drive (WD Elements SE). I am also choosing to install the grub bootloader to this disk (/dev/sdb) because I do not want anything modified on the internal drive. The installation appears to go okay, but when I try to boot to the usb drive, I get the error, "no boot sector on usb device" and it immediately falls back to my interal drive. I have tried this installation with both 10.10 (amd64) and 11.04 (amd64). How can I fix this?
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 have blown-out and dusted the interior of the case with a feather brush, reseated the heat-sink with lots of paste, reseated the heatsink with a thin layer of paste, I've disabled speedstep in the BIOS to get the thing to run @ 1.2ghz instead of its' rated 2.0ghz, I've cleaned and lubed the fans with 3-in-1 oil. Yet, It still overheats. It goes like this. I'm running Slack -current BTW.
Boot ok... XFCE4 starts ok... gkrellm starts ok... THM shows anywhere from 28 to 44C at this point... Konsole starts ok...THM kicks up to 48C Seamonkey starts...THM kicks to 50C Load a ..... video to give the processor a workout Within 2 mins THM spikes to 74C and fans start. THM drops to 50C within a minute or so and then fans stop... just let the machine sit for a minute...and...lockup Hard reset THM shows 66C during boot sequence this pattern repeats every time I try to use this machine.
Last week, i updated, my fedora. After that, during every boot up, I am getting a warning message like " Your hard disk may failing". It indicates that it is due to bad sectors. But I don't think so. There was a bug reported for a similar problem in fedora 11. I think it is not fixed yet. Hard disk is not having any problem during data access. Other OS including windows are not giving any warning message.
When I connect my flash drive into the USB port on my computer, it starts overheating and within 1 minute, its too hot to pull out with my bare fingers. But when I plugged it into USB port of my Pioneer CDJ 2000 (DJ player), it didnt overheat and it was able to read files (I did firmware update). Should I throw it in the trash and buy a new one? It's only 2 GB drive.
As you are probably aware that WD released new drives ranging from 1TB to 2TB with native support for 4K sector size. And as most of stuff written online is regarding Windows and their support for 4K, my question is has anyone already started to use it under linux?

I'm thinking about getting one of these drives: 1TB WD10EARS or 1.5TB WD15EARS
I'm using Debian Lenny so my questions are: is fdisk automatically recognizes that that drive is 4K drive, or it totally ignores it and partition is as 512byte one? In windows if no 4K support is available it would emulate it and performance would be downgraded. Do I need to enable any specific components in kernel so 4K drive is supported? I wanted to make sure there would be no data loss if I select 4K partition type.
Should the first bootable partition start from sector 1 on a hard disk? or Can it be created anywhere on the disk? I am using fdisk to create the bootable partition.
I want to simulate a bad block or sector on a drive or even a virtual drive image to test my data recovery distro. I wish I would have bookmarked when I read about it before. It was some type of low level command, I remember something about scsi subsystem or kernel thingabob.
So I finally bought an advanced format drive, the 2 TB Samsung f4. I will be using it on my slackware box, running slackware 12.2 with kernel 2.6.27-7. I intend to format the drive by hand with fdisk and start the first partition on sector 2048, or perhaps boot a livecd and format it with a newer version of fdisk or parted that will natively partition this drive correctly. My real question is, do I have to do anything special to add this drive to an existing LVM volume group? I'm thinking no, since LVM basically just breaks all your data into 4 MB chunks and spreads them across the pool of partitions you've defined, but I've found many conflicting opinions from searching google. To simplify things, I'm not using RAID of any sort, neither hardware nor mdraid.
I have 350GB external Western Digital USB hard Drive.When I try to remove it from the system by executing Safely Remove Drive menu the fedora 15 system gets stuck.The processor starts giving a hum sound and it goes on even if it is left for half an hour in the stuck state.The Mouse is not working and everything is halted.
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
i have installed fedora 14 with so many libraries ,development tools installed on my pc but i usually have to present some projects which can run on my system .........and can't be executed or compiled due to absence of libraries and tools there so, i there some way to so that i can use this current installation on my hard drive of my pc to some external media like external hard disk and plug and use that installation anywhere on any system..
It's many years since introducing of installation of Linux live CDs like Ubuntu from USB flash drives. I never been able to use such services on my 2GB KingStone flash drive, because it's sector size is 2048 and the famous linux error: "Not all ... support more than 512B sector size". Although I formatted my flash drive many times and even erased the whole partition table and cleared all flash contents with 0xFF values but it still has sector size of 2048.I want to know where the hell those softwares like "USB Startup Disk Creator" in ubuntu and kubuntu and fdisk in almost all linux distro's get to know that the sector size is 2048?
I wanted to check the first sector of my USB stick, and so I issued:dd -if=/dev/sda -bs=1024 -count=1It showed me all the weird characters from the data, then after it executed my bash prompt became corrupted with the same kind of characters! Also, everything I typed was like that. (see the picture)Luckly, it was just that tty that became like that.How can I fix the fonts after something like that happens, and how to prevent it from happening whenever I use dd again?
My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.
I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive. When mounting from file browser:
Code:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda,missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so The end of dmesg said the following:
Code:
dmesg | tail [ 82.130904] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)
my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:
Code:
# sudo e2fsck /dev/sda e2fsck 1.41.14 (22-Dec-2010) The filesystem size (according to the superblock) is 122096646 blocks The physical size of the device is 122096381 blocks
[code]....
this is as far as I've gotten. This drive holds over a decade's worth of work for me and is extremely valuable. I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. What is it that I need to do to restore my drive to working status?

I'm going to replace damaged HDDs in my server with new drives, which have sector size of 4096 bytes instead of 512. Does CentOS natively support such drives? If yes, since which version? If no, what actions should I take to correctly prepare such a drive to work. How to check that such a drive is correctly recognized by OS?
I have a laptop with only 30GB storage and I want to install Lubuntu in virtual box but Lubuntu needs 5GB of storage space which i dont have. Could i use an external 160GB hard drive to act as the hard drive for the virtual machine without affecting the files that are already on the external hard drive
I was hoping to install Fedora 15 x64 on my desktop on a seperate disk from Windows. I have tried about 15 times so far and keep getting errors. The same type of errors occur when trying Ubuntu 11.04 x64.
This is the spec of my PC:
Core i7 920 oc'ed to 4.00ghz (stable in Windows with temps under 60 degrees celcius at load) Asus Rampage II Extreme Sapphire Radeon 4890 6gb Ram Install disk is an empty WD Caviar Black 1TB (Also, not sure if this is relevant, two soundcards - M-Audio Audiophile & Asus Xonar)
This is the error (I can't get it all written down because it reboots too quickly, so I've written down a selection):
Fedora 11 dies nit recognize 2bd hard drive. Windows and fedora 9 both use it. When attempting to use anaconda it does not recognize the first hard drive. Drive recently installed.
