Invalid BS_jmpBoot in boot block: b7c45d + File system verify or repair failed
Posted: 29 Dec 2017, 07:36
Hi,
I have a WD 1 Tera external hard disk. This disk has all of my kids and work documents and is very important for me. Appreciate all your help here. Thanks so much in advance.
What happened?
- Today I was copying my kids pics to this drive, and was done. I tried to eject it in the normally way from my mac, but then received a message saying, I need to a force eject as some other app was using it. I didn't want to but then had no other option after 15 minutes as this got stuck. Selected a force eject option. After this, I plugged my external drive again, and then saw a message saying "the drive is not readable" and gave me some options, initialize, ignore etc. I selected initialize and then saw that my drive was recognizable. Ran the first aid via the diskutils, and then selected the specific drive and ran the first aid again, which is similar to what I ran from the command line below, and came across the below error:
$diskutil list

I learnt from the internet about test disk, and downloaded. So far am able to navigate and am here running the analyze sector. Selected the apple partition map..

Can someone please help if I'm going in the right direction or not. If yes, then what do I need to do next?
Thanks again,
