Clone a corrupted HDD.

hack3rcon · 07-02-2017, 10:35 AM

Hello
I have an external HDD and it has some problems. I like to clone it but it is not possible. I used below "dd" command:

Code:

$ sudo dd if=/dev/sde of=/media/jason/A0148B1C148AF516/hdd1.dd conv=noerror bs=4M

But I got :

Code:

And after sometime the size of output file was 0 byte. I used "ddrescue" too :

Code:

$ sudo ddrescue -d -r3 /dev/sde /media/jason/A0148B1C148AF516/hdd1.img

And result is:

Code:

GNU ddrescue 1.19
Press Ctrl-C to interrupt
rescued:    27414 MB,  errsize:       0 B,  current rate:   33161 kB/s
   ipos:    27414 MB,   errors:       0,    average rate:   30562 kB/s
   opos:    27414 MB, run time:   14.95 m,  successful read:       0 s ago
Copying non-tried blocks... Pass 1 (forwards)

It just copy 27 GB of my HDD. any idea to clone whole disk?

Thank you.

You can use CloneZilla, Macrium Reflect or similar, using a boot media.

Just let ddrescue run, at least until there have been no successful reads for at least an hour or two. That may take several days, but it will do the best it can. If the drive supports it, you might speed up the scan by using the "-l scterc" option in smartctl to restrict the time the drive spends trying to do its own error recovery. See the smartctl manpage for details.

Can you show me the full command?
I used "sudo smartctl -l scterc /dev/sdc" and I got:

Code:

smartctl 6.4 2014-10-07 r4002 [x86_64-linux-3.16.0-4-amd64] (local build)
Copyright (C) 2002-14, Bruce Allen, Christian Franke, www.smartmontools.org

Read Device Identity failed: scsi error unknown error (unexpected sense key)

A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

Any idea?

Is this drive connected via USB? It appears that the external enclosure has a USB bridge chip that does not support the needed commands for SMART. There is no workaround for that other than removing the drive from the enclosure and connecting it directly via SATA. (That's assuming that the bare drive actually has an SATA interface. In particular, some WD external drives get rid of the bridge by having the USB interface on the drive itself, so there is no alternative there.)

Yes, It is USB. It is not WD it is Seagate.

never mind, try to take out the hdd and use a sata cable to connect it to your PC.

Before doing that, you might want to see whether the drive supports Error Recovery Control at all. Run "hdparm -I /dev/sdc" and see whether "SCT Error Recovery Control (AC3)" is listed as a supported feature.

Try another cage, adapter, usb cable, power supply.
I had problems with disk that resolved by usb cable replacement.

The bridge chipset can also go bad.
