It seems that Linux tries to auto-mount the drive and guess the file system on it when booting. Any way to stop it? I have a broken drive which show a lot of ATA error, and takes 10 minutes to boot up. Any way to skip it?

Can I plug in the drive after boot up and do raw read, just like what MHDD can do? ddrescue complain that it can't find the drive.

is it read hat ur using? or which distro?
and the Q is why linux? what do u expect more from it?

I use R.I.P Linux distro, since I need to use smartctl and hdparm to do some early evaluation.
Any low level software like MHDD/Victoria for Linux?
I just want to do raw clone.
GHOST shows the drive but grayed out when doing disk to disk clone,
True Image does not work (forgot how it does not work)
ddrescue depends on Linux kernel, if the drive not detected, nothing can be done.

seems that u have alot of bad sectors and those utilities will not eliminate them
Clone with bad sectors is also waste of time if u have alot of them

There's no point, just use the MHDD or Victoria boot disc

joe1203 the reason why ur here is that: u dono
and since u dono, u needed advices, well, i did which hope will work, if not then i think i tried same as the others here (drc)

if u like anyone`s advice and worked with u this is good,
but if u see things u don`t seem to help you then i prefer if u ignore that msg instead of replying on that behave.

really u never know, one day u will be back again, people who are looking @ ur behavior here will surly ignore ur questions later, this is my advice to u man nothing more nothing less.

and good luck with ur hdd all the best

Hi joe1203,
The reason drc mentioned mhdd & victoria boot disks is that it doesnt matter what os your running.
Regarding your comment I think youve just shot yourself in the foot & your chances of now getting help is probably slim to none.

I just feel drc's first reply is unfriendly, maybe i am wrong.

Moreover, I have stated I need smartctl and hdparm, using MHDD/Victoria bootdisc can't run them.

In case no one knows how to do raw read under Linux, I will drop this idea.

>From wiki:

>hdparm has a more serious drawback: it can crash a computer and make data on its disk inaccessible if certain parameters are misused. Out of approximately sixty-seven parameters, several are dangerous and could result in "massive filesystem corruption" when used indiscriminately.

Like stated in prior posts, if you want to see SMART values just run MHDD. It works directly with the hard drive. Not OS dependent, which is a problem you have as you described the drive takes a long time to boot, etc.

With MHDD, you can see if your drive registers correctly with correct model and capacity.
The check SMART out to see how degraded your drive is.
Lastly to confirm SMART findings, run a scan to get an idea of bad sector frequency and location. Not to mention you can skip a bunch of sectors at the time using the arrow buttons if drive is acting up.

Too many bad sectors? Stop scan and power drive off immediately.

Next would be tough decision time - have to consider DR professional service as more advanced tools are needed in order to recover the data successfully - or continue with other tools and potentially kill the drive and decrease recovery chances tremendously.

Yeah! Finally figure out myself
It needs to recompile Linux kernel to disable file system automount
