Re: [Dorset] OT Disk drive recovery

2014-06-01 Thread Andrew

That is possible and I have done it myself when I blew up a hard disk PCB.

There could be a slight problem with that if either of the two hard 
disks has detected bad blocks, the hard disk may store bad block 
re-mapping details in the flash chip on the PCB. Even if either of them 
has done this you'll probably get most data back though. A lot more than 
with no working PCB.

Re: Can I re-install Ubuntu (with a new version) without

For many years, across different distros and releases of distros, I have
kept no personal data (Documents, Pictures etc) in /home. I created a
separate partition containing all my data, including .mozilla and
.thunderbird, and created symlinks from /home. This means that /home
only contains all those . and . objects that vary from
release to release, so I don't care that it is created on each new install.
I recommend that approach.

I didn't do the above but did a complete copy of /home as well as an 
incremental backup.


(Graeme, can you enforce your technique on a multi-user system?)

In fact, the ISO of 14.04 has a standard option of upgrading from 
13.10.  I selected that and it worked well.  That's in contrast to the 
failures I was getting with the upgrade-in-place option.


My home files seem to be as before.  An oddity is the GRUB situation.  
The existing configuration was ignored and GRUB was re-initialised.  
That meant that I did the usual procedure:  I edited  /etc/default/grub, 
saved it and immediately rebooted.  I then wondered why there was no 
change and eventually remembered to run update-grub!


(BTW, I've forgotten how to remove the memtest entries from the menu.  
Any suggestions?)


The "upgrade" promised to re-install all my existing applications but 
then when it came to actually doing it , it told me it couldn't do one 
and gave up.  The missing ones I've identified are just Terminator, 
qBittorrent, and Kate - nothing complicated.


Thanks,
John

Hi CHristopher,

I can't offer to do the forensic job myself but I did see somebody blog
once that if it is the PCB that has failed, and if you can get hold of an
identical drive, then it's possible to swap over the electronics and access
the data in that way (and immediately write it to a backup of course!)

hth and good luck!

victor

see you Tuesday perhaps?

[Dorset] OT Disk drive recovery

2014-06-01 Thread CPK Smithies
I've had a disk drive die on me (A Seagate Barracuda 1Tb). It looks like
it's a PCB fail rather than anything mechanical. I'm aware of various
"data recovery" firms who will happily charge £400 to sort out a drive
like this. But maybe there is someone in the area who will tackle this
sort of thing on a low priority basis for less than ransom money? If
anyone knows of anyone capable I'd be grateful for recommendations.

Regards to all,

CPKS
