Bizarre Change in Filesystem Type after Testdisk repair

#1 Postby stevesr0 » 01 Mar 2012, 13:17

Firstly, thanks for the forum.

Second, I wish to report my recent first experience using Testdisk to examine my partition and repair it.

I decided to try Testdisk because my system started to spontaneously freeze and occasionally reboot after shutdown. When this happened, sometimes I was able to switch to a command line and note that a stream of /dev/sda i/o errors sector xxxxxx (mostly one sector with bursts of other sectors). Using Spinrite 6.0 on the disk (level 2 and level 4) has not changed these occurrences.

I went through the analyze, quick search assessments with apparent normal findings (except that the bootable partition switched from one to the other). Then I performed the deeper search and this revealed many duplicate and extra entries.

Testdisk Log, follows. It looks full of redundancies to me, since I went back and forth before finally deciding it was "safe" to write. I think it includes two sessions (second part appended).

No extended partition

TestDisk exited normally."

I was thrilled when the system rebooted apparently normally after exiting testdisk and shutting down.

HOWEVER, I noticed that the swap partition failed to load during the boot.

After boot, the system seems to be functioning normally.

However, the extended partition which contains my swap partition is now listed with a Fat Windows 95 code (I think it is the 0f WIN95: Extended partition, LBA-mapped one). Prior to the testdisk rewrite, it was listed as a code 5 in fdisk -l.

** I think this may be related to the failure of testdisk to detect an extended partition (or my failure to run the specific extended partition analysis, which I now recall was an additional option on the result screen at the end of the "Deeper Search".

I don't know if this is important? I don't know the practical implications of a particular filesystem identification for an extended partition, since these are only containers for the logical partitions within them.

Gparted detects the extended and swap partitions apparently normally, but since the swap "failed" to load at boot, it suggests that the extended partition (and the swap partition inside it) is not being recognized.

So, I wonder whether I should change the extended partition code back to 5, and if so, with which tool, fdisk or Gparted or testdisk or ...?

Thanks again for providing testdisk and for the forum.

Steve

The extended partition must be an "Extended LBA" because the ending cylinder is greater than 1023.

Check your /etc/fstab, maybe the swap partition isn't listed as /dev/sda5.

Note that TestDisk 6.14-WIP is better than previous versions when dealing with partitions aligned on cylinder boundaries and aligned on 1MB boundaries.

Your hard disk contains bad sectors, you should clone it to a new empty disk as described in http://www.cgsecurity.org/wiki/Damaged_Hard_Disk

Hi again.

After using SpinRite, I ran the Hitachi Drive Fitness test on this hard drive. It found no errors with the drive.

I also tested using the smartmontools and again no problem was detected.

Then I backed up the files I care about.

Then, with Gparted (running from a live CD), I deleted the (logical) swap partition and the (win95LBA) extended partition it was in. Then in the same Gparted session, I created a new extended partition (Type 5, according to fdisk) and resized it (and moving it "leftward" by shrinking the preceding partitions) and then creating a new (logical) Linux swap partition within it.

When I ran testdisk after this, it still displayed errors and so, I ended up deleting the swap and extended partitions.

Subsequently, I have run testdisk while booted from a liveCD and while booted from the hard drive itself.

When I attempt to rewrite the partition table using testdisk, it doesn't change anything after the reboot.

Note that the hard disk seems to be functioning ok at this time and I am unaware of missing data.

I am puzzled what I am doing wrong in getting rid of the extra partition entries.

Appreciate comments, advice and explanation.

Thanks again.

Steve Rinsler

P.S. I have attached the log file twice but don't see it in the preview.

Hopefully, it will appear after submission

You are right, the "Input/output error" message from the ntfs library doesn't mean there are bad sectors. My mistake.

I still don't understand the problem with the logical partition but if you don't need more than 4 partitions, there is no need to create an extended partition, you can set them as primary.

Hi again,

I appreciate the advice about not needing to maintain an extended partition. Note that I DON'T have one at this time (nor a swap partition). Both fdisk and gparted report two partitions (an NTFS [Type 7] and a Linux [Tyoe 83]). Only testdisk is detecting problems with these partitions and additional problematic partitions.

Whenever I have tried to attach the log file to a reply, an error message is displayed "The extension log is not allowed." I also tried changing the name to testdisklog.txt and the error message changed to "The extension txt is not allowed.

So, the text of my latest log file follows.

Looking at it, I note the disk geometry for the Linux partition is 207 and 18 rather than 254 and 63. I think this is incorrect.

In addition, the two Linux swap partitions detected on the "Quick Search" don't exist, and on both the "Quick" and "Deeper" searches, the Linux partition is found to have 207/18 rather than 254/63 geometry.

The "Deeper Search" detects many other nonexistent partitions.

I have the following questions:

Since I am not CURRENTLY experiencing problems obvious data corruption problems with this computer and the drive is said to be OK by SpinRite, smartmotools and the Hitachi Fitness Test and neither fdisk nor Gparted is finding errors in the partitions,

Should I not try to fix anything at this time (just continue to use the computer and see what happens),

or

Should I try just modifying the Linux partition geometry (can two partitions on the same drive have different geometries?) reported by testdisk?

or

Should I fix/delete the partitions found with the "Quick Search" (changing geometry of the Linux drive and deleting the two Linux Swap partitions)?

or

Should I try "fixing" everything ("Quick" and "Deeper" search abnormalities?

Rather confused at this point...

Thanks,

Steve

Re: Bizarre Change in Filesystem Type after Testdisk repair

But, why won't test disk delete the damaged partitions when I use the "wire" command?

I have tried this several times and on reboot, test disk again finds the same damaged partitions.

Thanks for comments and assistance.

As long as some sectors contains the signature specific to filesystem, TestDisk will always find the same partitions. It's why running TestDisk once or ten times should always give the same results.
Writing a new partition table will only change the partition list as seen by your OS or in TestDisk Analyse screen (before choosing Quick Search) or TestDisk Advanced menu.
On your first post you wrote about crc error, they may be due to bad sectors. Bad sectors are a physical problem, they can't be repaired. At best, SMART monitoring is enabled in the BIOS or at the OS level and the disk will replace some bad sectors with spare sectors (limited quantities). If there are bad sectors, the best is to clone the HD to a new empty disk as explained in http://www.cgsecurity.org/wiki/Damaged_Hard_Disk

Thanks for response.

I am trying to understand test disk better, partly because of my concerns about my hard drive and partly in order to give a presentation about it to our local Linux users group.

After the messages about I/o errors in the initial testdisk runs, I deleted the extended partition and enclosed swap partition and checked the hard drive with the hitachi fitness test and smartmontools which both found no problems.

I then checked with fsck and ext2fsck. When the drive was mounted, these tests showed errors, but when I booted from a Knoppix live cd and checked them unjointed, they were said to be free of errors.

The most recent testdisk runs (Mar 5) don't show I/o errors, so I figure that the remaining problems are software related.

So, if there are sectors (not partitions?) with a filesystem signature that I need to delete/remove/fix, how do I do that?

Is that something I can do with testdisk?

Obviously, I lack understanding of how to use testdisk in my particular situation, in spite of reading through the documentation.

Appreciate any clarification you can offer.

Thanks,

Steve

Now TestDisk don't show any error, so what is the remaining problem ?

On the deeper search, it displays multiple extra partitions (10) and when I mark the 8 damaged ones for deletion and ask the program to write the change to the partition table, hit "Y" to confirm this and then quit test disk. After I reboot and rerun deeper search, the program still reports the same 10 partitions.

Note that all 10 partitions are marked as "D" when deeper search finishes it's analysis. All I do is change the two "correct" partitions to "P" and "*" and then hit/select enter.

Am I supposed to do something after changing the two partitions status, before trying to write to the partition table?

(like rerun analyse, quick search and deeper search again BEFORE selecting "write" and "Y"?)
