harddisk issues... noooooooo!!!

[R4NG3R]

when i try to mount my second harddisk i get this error, and i just randomly got this error when i woke up this morning:

shell> SCSI disk error: host 0 channel 0 id 4 lun 0 return code = 28000002
Info f ld=0x28b, Current sd08:11: sense key Hardware Error
Additional sense indicates Mechanical positioning error
I/O error: dev 08:11, sector 588
_


what the hell happend!!! what do i need to do???

Umm... I'm not expert in linux, but just by what it is saying is that the HD has failed. Can you access the drive else were?

[R4NG3R]

nope, i can mount it, but when i try to go to

/mnt/hda2

i get an I/O Error.

tried not mounting it and running an e2fsck on it?

[R4NG3R]

nope, how do i run that?

[Trillian]

man e2fsck

well, it only works of you've got a ext3 or ext2 fs on it, I think.

e2fsck [drive]

where the drive is something like /dev/hdb1
the /dev/hdb stands for the second hard drive,
and the /dev/hdb1 stands for the 1st partition of your 2nd harddrive.

So if you've got 3 partitions on your 2nd hard drive, being something like..
1st: linux native ext3
2nd: windows FAT32
3rd: linux swap

then you want to run a e2fsck on the first partition, so type (as root) "e2fsck /dev/hdb1"
You have to do this as root, and **only** on a umounted device.

my 2nd hard disk is /dev/hda2 i typed
input:
shell> e2fsck /dev/hda2

output:
e2fsck 1.32 (09-Nov-2002)
e2fsck: No such device while trying to open /dev/hda2

The superblock could not be read or does not describe a rorect ext2 filesystem. If the divice is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
shell>

when i input:
shell> e2fsck -b 8193 /dev/hda2

i got the same output.

My scsi drives show as hdc* where * is a number

Your 2nd is not /dev/hda2, if you don't have any scsi drives.
Otherwise, copy your /etc/fstab here, so that i can have a look at your partitions.
But you were prolly referring to your 2nd partition, instead of the hard drive? :?

Because the error message is telling you your /dev/hda2 does not have a ext2 (or a ext3) filesystem, or that it does not exist.

Okay, here's what you can do:

cfdisk

You might get something like this:

								  cfdisk 2.11z
 
 							  Disk Drive: /dev/hda
 					    Size: 80000000000 bytes, 80.0 GB
 			 Heads: 16   Sectors per Track: 63   Cylinders: 155009
 
 	Name	    Flags	  Part Type  FS Type		  [Label]		Size (MB)
  ------------------------------------------------------------------------------
 	hda1	    Boot		Primary   Win95 FAT32 (LBA)			    25928.15 
 	hda5	    Boot		Logical   Linux ext3					   53230.15
     hda6				    Logical   Linux swap						 841.24
 
 
 
 
 
 
 
 
 
 	 [Bootable]  [ Delete ]  [  Help  ]  [Maximize]  [ Print  ]
 	 [  Quit  ]  [  Type  ]  [ Units  ]  [ Write  ]

If so, copy this. Then, do the following:

cfdisk /dev/hdb

If that results in

 FATAL ERROR: Cannot open disk drive
 						  Press any key to exit cfdisk

, then you dun have a 2nd non-scsi drive.


'coz I'm wondering whether you do or dun have a 2nd hard drive here. And whether you know the difference between a partition and a harddive.

no offence

[R4NG3R]

yes i do know the difference and yes i do have 2 different physical hard disks. and

cfdisk

does not work.

ok. erm, maybe your system doesnt have cfdisk, you could try fdisk. That's a more console type of thing.

Then,. are you sure your 2nd hard drive is located on /dev/hda2?

[R4NG3R]

well.. i always mount it to:

mount /dev/sdb1.. wait... o. it's:

/dev/sdb1

::feels like dumbass::

yeah i have fdisk

you've got a scsi hd then! ah.
Now you can do:
e2fsck /dev/sdb1
Goodluck!

[R4NG3R]

could i use fdisk to reformat the second disk if it's unmounted? it's clear of all files right now... so could i reformat and partition it?
