Need Linux help before I can use RStudio
Posted: Fri Apr 08, 2016 10:04 am
Hey all, RStudio isn't able to see a drive b/c (I think) a partition is being incorrectly reported, perhaps someone can help?
I know just enough about Linux to mess things up, so apologies in advance. I have tried looking at some of the other threads similar to this, but none of the answers seem to help. I have a 4TB Seagate Central drive that I need to get data off, but I am unable to, hoping you can help.
Here is what I have tried so far, I've 'bolded' the commands I entered
pc1@PC1:/$ sudo parted -l
pc1@PC1:/$ sudo gdisk /dev/sdb
Command (? for help): i
Command (? for help): v
sudo fixparts /dev/sdb
(parted) rescue start
So this is as far as I can get...which is just far enough for it to keep telling me what is wrong and what to do to fix it, I just don't know how to go about that - it actually seems like it isn't that hard, but I don't want to mess around with it any more at this point b/c I don't know what I am doing. I've checked out the info here -->http://www.rodsbooks.com/gdisk/repairing.html but don't understand it enough to proceed with confidence - HELP!

Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Caution! After loading partitions, the CRC doesn't check out!
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged

Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.
