is my hard drive deiying or have i been hacked?


major problem! one ove my hard disks in my server is the problem i think!
i will explain the situation first!!

on the one IDE disk i have all the others are scsi. i keep all backed up software on it it consists on on 80gb ext3 partition with one folder on it called software in that folder there was 3 more folders! one called windows one called solaris and there was one called LINUX but the linux one has disapeared! wel almost disabeared!

this disk is in my server which has no moniter, keyboard or mouse so i can only look at things on it through ssh and webmin if i connect to the sever using ssh and cd to to the software directory and ls to see whats in the folder i get the follwing

/usr/bin/ls: linux: input/output error
solaris/ windows/

i can access the solaris and windows folders no probobs but the linux one doesnt appear but hear is the realy intresting thing!!!! in webmin if i use the file manager the linux folder will show up but not as a folder and with a file size of 0kb unlike all the other folders with a file size of 4kb when i click on it i get the input output error again. however i share the linux folder on my website for the linux downloads could it be a hack?

can any one help please?

"could it be a hack?"

This is much more likely to be a corrupt file system caused by a disk hardware error. I suggest that you umount the partition and run fsck against it:

umount /dev/hda1
fsck -t ext3 /dev/hda1

and see if that will fix the problem.

You'll want to let it finish to see if it can correct any of the problems, but definitely data corruption or loss is a possibility at this time. Hope you made backups if its important data..

Next time you can avoid all of the fsck questions by using the -a option.
fsck -a -t ext3 /dev/hda1

You will have to recover your data from backup. You should format the partition before you restore data to it.

"could this be a hardware problem?"

The corrupt file system was probably caused by a hardware error. I suggest that you run badblocks on the partition. See man badblocks.

Then format the partition. If you have a bad spot on the hard drive then the format should tell you that.

If the hardware error is bad enough that you cannot get through a format and a restore then you need to replace the hard drive.

If the restore goes OK and if the hardware problem is an intermittent error then it may or may not cause you problems again.

Don't forget to run a badblocks scan of the partition when you reformat it. Unfortunately, if there are a lot of bad sectors, it may be a sign that the disk is on its way out, and it would be best to try to pay a visit to the facility where the server is located and replace it.

I just had the same problems with a new system and a new Mandrake 10.0 community install, apparently, the newer versions of limux are having problems with mixed drives, that's just what I had, an IDE and a SATA.

I removed the IDE, and the problem went away....

As for the back-up program, someone else will have to answer that one....

Just make sure you don't use Norton Ghost, it does a bad job.... as I recall, it's dependent on your (hardware) set-up, but why take the chance.... especially if you're having problems already.

You could use an image copy program like dd to copy the whole mess to a different partition. Then you will have a mess in a new location. You could run fsck against the new mess in the hopes that fsck could straighten out the mess if it doesn't also have to deal with bad spots on the hard drive. The odds are against this idea working but it wouldn't hurt to try if you have the time and the spare disk space.

testdisk ( http://www.cgsecurity.org ) might rescue some of that for you, but you're probably better off just making up a list file of the MD5SUMS and .isos that you downloaded (full URLs) and using wget to download them all in the background while you do something else.

A while back, I threw a script together to create separate directories to house each distro and release, and download each to its own spot.
nohup the script, and let her rip for a few days.
