发帖数: 33 | 1 Thinkpad 450s reported SSD error. Got a Samsung 850 Pro and tried to make a
clone out of the old SSD. The Samsung software Data Migration got stuck at
11%. There might be bad sectors. Then searched and found some free software
called EaseUS, but it could not find the new SSD (connected with laptop with
an adapter).
Any one in a similar situation? Any suggestion is appreciated! | a***e

重装 takes too much time. The laptop is dual-boot (Win7 and Ubuntu).
Searched online and found that EaseUS Todo was claimed to be able to handle
bad sectors. But the software could not find the new SSD. The software was
made by Chengdu Yiwo Tech, a Chinese firm?
Macrium Reflect got stuck with a read error.
Any suggestion besides reinstalling everything?

I've cloned over a dozen drives between computers (large drive to small,
small to large), always use a Ubuntu live USB, and the dd/pv command, never
had any issue.
for bad sectors, you need to use disk scan software to label those sectors
as "bad", then OS will not attempt to read from those locations.
If you use Ubuntu live usb, install a program called "badblocks" and use it
to scan your drive. I am sure you can find something similar for windows.

发帖数: 33 | 7 FangQ,
I tried ddrescue (a Linux utility) and it cloned the defective SSD and
claimed a success. ddrescue reported errors of 2MB. But somehow when I tried
to reboot the computer it did not boot from the clone (I did choose the
clone as the boot device using the F12 key).
I tried Clonezilla that runs on a Ubuntu live USB, but it stopped working
due to disk errors.
Have you had any experience with the above utilities?
Let me make sure I understand your suggestion:
1. Make a Ubuntu live USB
2. install badblocks utility on the USB
3. Use dd/pv to clone
Thanks!

tried
if booting is a problem, you may repair MBR or grub to see if that helps
https://www.cyberciti.biz/faq/howto-copy-mbr/
https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows
or if it is UEFI, follow this page (never tried myself)
http://help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_UEFI_or_Legacy_mode
still, even you can boot, keep in mind that your system has broken/missing
files, your system is still unstable. what you can do is to install a new
system (same version, same distro), mount the restored drive, and then
rsync -tav /drive/of/recovery/ /drive/of/newsystem
or use "cp -a" to merge the two systems.
if I were you, I would only care about restoring the files in /home. I won't
hesitate to install a brand new system, mount the recovered /home, and
reinstall the customized packages using apt-get. It only takes a few hours
to reconfigure a new system, compared to days or weeks for you to restore
the exactly the same old system.
