Hi, To make it clear Samson,
I took OS backup of laptop using mac.ref of your version and then copied all other drives. I tested the recovery usb, by booting laptop to check whether it is booting. No problem with laptop as i have usb boot option there.
Then , i tried to take the back of pc, with mac.ref. Since download contain much files. I just moved the files from mydoucments and download folders from c: drive to D drive to reduce the size of c: drive. Then i tried, when the error came.
I already ran chkdsk on pc and ext hdd on my pc, which took hours for ext.hdd and about 2 hours in the pc hard disk. no problem was deducted and if at all, it would have been fixed with me opting chkdsk /r.
Now, my problem is , can i reformat the ext.hdd drive by moving the files stored in it to my pc in a folder in D drive. It was preloaded with some files. I am afraid that if i delete those, i may loose the easy connection.
Can i just copy the mmring backup file of laptop to the D drive and then format it?
I did diannosis with DST driveshort test which passed. I then opted for fast fix all test, in the hope that it would fix, but it failed at 77 percent on two counts.
Regarding robocopy, i just copied using it to copy files from d.drive on pc to my ext.hdd. drive, with success rate of 100 percent , fastly.
I could use the recovery usb (macrium rescue) on pc, only after taking the backup.
when i had the crc problem, my pc went out of order and i could not boot. I used plop.boot a linux program, to boot from pendrive, usb. The option is not there in my pc, which is having older hardwares. i used plop boot iso to retrieve my computer by going to the repair my computer in install window options. I just clicked repair instead of install option in the starting windows install screen. Now, i could boot my computer and view all the files.
