have same md5 errors with ext4 second partition.I have interesting situation with that recover:
First, I backed up only sd-ext (I have fat32 for link2sd), it backed up without any md5 errors.
After that I backed up system (without errors);
data (...Generating data md5...sh: cd: line 1: can't cd to ces.xml....Done....Verifying data md5...sh: cd: line 1: can't cd to ces.xml....MD5 Error: cd ces.xml && md5sum -c data.win.md5...)
android.secure (...Backing up .android_secure. tar: ./ces.xmland-sec.win: file is the archive; skipping....Done....Generating .android_secure md5...sh: cd: line 1: can't cd to ces.xml....Done....Verifying .android_secure md5...sh: cd: line 1: can't cd to ces.xml
....MD5 Error: cd ces.xml && md5sum -c and-sec.win.md5...Done.)
sd-ext (Generating sd-ext md5...sh: cd: line 1: can't cd to ces.xml....Done....Verifying sd-ext md5...sh: cd: line 1: can't cd to ces.xml....MD5 Error: cd ces.xml && md5sum -c sd-ext.win.md5...
Can provide the whole log.
Is where any solution?
may it be because of link2sd incompatibility?
