[dba-Tech] SpinRite or? Finished!

[Jim Lawrence]

Hi Lambert:

That is an excellent set of links and software.

I have played with these tools before but was not sure whether Gustav would be interested in using anything other than Microsoft products to solve the problem...that was my bad. :-(

This site 
http://www.tomshardware.com/forum/272053-32-disk-sectors-incredibly-slow-back-process
has the comment:


Data recovery professionals will tell you that HDD Regenerator and Spinrite are potential drive killers. Your drive appears to have bad media or weak heads. SpinRite will hammer away at a bad sector up to several thousand times, while hoping for 1 good read. This methodology can accelerate the total failure of your drive.

Your best DIY approach would be to clone your drive sector-by-sector using a tool that knows how to work around bad sectors, and then use data recovery software on the clone. 

Some freeware cloning tools are ... 

dd_rescue: http://www.garloff.de/kurt/linux/ddrescue/ 
ddrescue: http://www.gnu.org/software/ddrescue/ddrescue.html 

Comparison between ddrescue and dd_rescue: 
http://www.forensicswiki.org/wiki/Ddrescue 

Ddrescue can perform multipass cloning. It clones the easy sectors on the first pass, and attempts the more difficult ones on subsequent passes. It can also clone your drive in reverse, thereby disabling lookahead caching. It keeps a log, allowing it to resume after an interruption. 

The following thread discusses various freeware and commercial cloning tools:

Hi all

Sadly, after three hours this tool reported "Too many bad sectors" and refused to proceed.
That's probably not the truth but the result of a time-out due to this drive's extremely slow response.

Seems like I'm left with a goodie for the recycle bin ...

Hi Gary and John

It's a WD drive and I have located the "Western Digital Data LifeGuard Diagnostics - WinDlg (DLGDIAG for Windows)".

Will try tomorrow if it can do anything.

Same for WD drives.

Glad to hear you got the data you needed off of it. You could perhaps check on the drive manufacturers site for a low level format program.
I have heard that Seagate had one for it's drives at one time.
