gpart

[sbininit]

I noticed there is no gpart in the new Knoppix 6.2 release. gpart was extremely useful to me a while back when I lost my partition table. I was able to use Knoppix 5.3.1 which already has gpart on it to recover my partition table and boot my computer again. Everything I own was on those partitions. I have it backed up on an external drive but still think of the aggravation.


I tryed installing from tar .gz file but after make is executed it comes back with many errors. Same thing goes for the Ubuntu live cd. Its no problem intalling it with synaptic to my HD Ubuntu install. If you cant boot the HD it does little good though. LOL

I'm loving 6.2

if you are online try typing


sudo apt-get install parted.

or even

sudo apt-get install gparted

that should sort the problem in short order

I think he means gpart http://packages.debian.org/lenny/gpart
which available through apt as well. He could also download the package to portable media and install using dpkg.

I down loaded it from that actual site but I can't get it to install for some reason. when I cd into the folder and run make It comes back with a bunch of errors whick I have no clue how to decipher.

I followed the instuctions in the Install readme if I understand them correctly:


gpart Compilation and Installation


Up to now a configure script for gpart does not seem necessary,
it should compile under Linux and FreeBSD using GNU cc and GNU
make.

Steps to compile and install:

- change the installation directory prefix "prefix" in the
file "inst.defs". The default is "/usr/local".

- type "make".
- if no errors were encountered, type "make install".

It is a good idea to read the man page before starting to
play around.





I changed prefix to "prefix" perhaps this is incorrect

If you downloaded the .deb you only need to use
dpkg -i gpart_0.1h-4.1_i386.deb , or if you have internet acces
aptitude update && aptitude install gpart Compilation isnt necessary.

Thanks for the suggestions but I cant seem to download a gpart .deb file anywhere for the first command and the second one yields these errors:

Lets try it another way then. In a root terminal type:
wget http://ftp.us.debian.org/debian/pool/main/g/gpart/gpart_0.1h-4.1_i386.deb

and then
dpkg -i gpart_0.1h-4.1_i386.deb

[OErjan]

another tool that can recovver lost partitions and the like is testdisk by the way

testdisk agravates me though. Once you wait on it to scan for an hour then you get to a place where you cant go back and have to do it all over again. I haven't found a way back from that point if there is one.

Thanks I couldn't get it with wget for some reason-

but I manually found found the .deb and opened it with debi package installer and now it works.

i do not quite "trust" gpart, mainly cause of the tendency to make wrong diagnosis of large disk geometries, it is slightly unstable above 1024 cylinders (which is quite common today)

[Capricorny]

I had a suspicion, and tried the address given here, w/o the http:// prefix:


root@Microknoppix:/home/knoppix# wget ftp.us.debian.org/debian/pool/main/g/gpart/gpart_0.1h-4.1_i386.deb

So, nothing wrong with the advice, really. And wget is your friend.

Is there a better way to recover the partition table? gpart rocked for me on that particular occasion. It might not the next time around. Maybe thats why it isn't included on Knoppix6.2.

[OErjan]

sadly every tool has it's limits, to eliminate errors I use several to get all information I can on the disk first
smartmontools
fdisk
sfdisk
testdisk

also I frequently use ddrescue and regular dd with flags conv=noerror,sync to "save" images of drives, it takes forever on large disks but it can save me in long run.
also I frequently use gzip to compress the image.

dd if=/dev/sdaX conv=noerror,sync | gzip -9 > /dev/sdbY/image.gz

sometimes I have used hex-edit to "rescue" important documents form such drive-images of damaged disks, it can be, uhm challenging but beter than total loss.
this is a jungle, I have been called by friends and friends of friends... to rescue "crashed" computers for two decades+ and I have only scratched the surface over that time, i have no banks of circuitboards from HDD's (ok a few), no clean rooms... i just try as best i can, if i see i can not do anything i say so and inform them about the more competent alternatives, sadly those come at a cost, some opt for that others not.

Will dd work when you cant actually see that the hard drive exists with fdisk, df, or blkid?

Hey-

note the extra http here: http://http//ftp.us.debian.org/ - happens all the time, IMHO
