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?

i dont know if this is possible and i have looked everywhere and all i can find is info on other businesses billing and now how to set up a cloud to do this. i wish there was some kind of tutorial for this. if anyone can direct me to some good notes/tutorials that would be very helpful. this could be a big changing point in my business if i can do this. it would save a lot of time and cash.
I have a weird problem here with a 9.04 server. We have a raid 5 disk formatted in EXT4 which remounted automatically when we accessed to the lost+found folder which is in the root of that disk.
I tried to delete it but I can't. It's a bit annoying because I have to prevent all users and backups to access to that folder.
I have samba server(Fedora 11) here,but when I want to access to it from WindowXP ,the first time you need to tap in user name and password.But the next time ,you automatically log in Samba server with the user name as the first time you used.

I have a very basic problem: My computer is attached to various light switches, central heating, powered windows etc. via RS232 and USB, using homemade custom logic boards. With this I can switch on and off lights, regulate room temperature, open windows etc. all by running some shell scripts on my system. I would now like to create a simple web frontend for this home automation.
What I want is a basic website with buttons, and when someone clicks a button on that website I want the webserver (apache ? ) to execute a script on the the server machine, triggering the rs232 hardware. The website is to be served by apache to make use of an existing structure. How (in what language) could I accomplish that? Javascript and Java are obviously out since they execute on the client, as far as I know PHP can't access the shell (which is probably a good thing), so what's left?
CGI? This will be deployed on an isolated private network secured the old-fashioned way (steel doors, guard dogs, landmines...), so I am not overly concerned about security, but of course it would be nice if the implementation offered at least some basic resistance to bored script kiddies...

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 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.
The next day that went up to 110
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?
I recently buy a Corsair F60, and F14 (and F11) said there is MANY bad sectors on my SSD. Is it a smartctl bug ? how can I confirm or infirm that ?

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 RelatedI've been attempting to figure this out for about 4 days straight, so far it has not been fruitful. I've installed Ubuntu 10.04 server onto my former gaming system, Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz, 2 cores with 2 GB ram. Overkill I'm sure, especially for a simple personal voip, htpc, storage server.
The problem is only noticeable when I have the vent server running, on the 10.04 server, and I attempt to connect to it through the LAN via the client on my windows computerEverything works fine and connects, LAN and from the outside, as long as the server is set to DHCP. However when attempting to switch to a static IP address, the vent client will not detect the vent server at all.Aside from an annoyance at having to stick with DHCP, I am still curious as to why the static settings will not function. Something so simple has turned into something quite difficult.
I can still connect to the Webmin interface and Putty into server with either DHCP or static IP enabled.I've performed the following troubleshooting steps so far:1) Followed the directions at https://help.ubuntu.com/8.04/serverg...iguration.html2) Edited the /etc/network/interfaces file through the CLI with nano and through notepad on the windows computer3) Through Webmin I've assigned the static IP, although for some reason it does not include a gateway field.4) I've rebooted the server5) I've issued the CLI

My 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 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
Question 1. Does gparted etc. just write to the MBR? Question 2. Is this the only record of the partition table? Question 3. How do i find the sectors that the partitions occupy?

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.
