Restoring partition table of HFS+ partition

My sister has an old mac, along with an HFS+ harddrive that had pictures etc. on it. I made a stupid attempt to mount the disk with the appropriate read/write rights from my Linux partition before making a full image of the disk. Something went wrong in the mounting procedure, which corrupted the partition table. I immediately made an image of the disk to not do any further damage.

Running photorec does recover a ton of files, so my hunch is that the bulk of the disk is OK, and that I really only messed up the partition table. I have tried to fix the partition table using fsck on my Debian machine. It did make an attempt to fix the disk, but in the end returns 'Invalid B-tree node size'. I then also tried testdisk, which finds partitions, but is unable to fix anything as it concerns an HFS+ partition. It suggests the use of parted to rescue the disk, but since it is a disk image and not a mounted partition I am not sure how to proceed. I have mounted the image and opened it in parted, but in parted I cannot find a way to proceed.

I have access to an iOS machine if I need to, although I don't own one myself (the laptop that disk belonged to no longer works). Does anyone have experience with a similar problem, or does someone know how to proceed?

certain keys on my keyboard dont work when "cold"

Hi guys, i have a Lenovo Y520-15IKBN (80WK) and certain keys on the keyboard don't work (e,g,h,8,9,Fn...) but only when the weather is cold. for example in the winter it used to work after certain amount of time when i first boot the laptop and stops working when i stop using it for a while, but now that the weather is hot it works just fine except for the first couple of minutes or when its colder. of course i do realise that it has nothing to do with the outside weather but with the temperature of the computer itself. can someone explain to me why this is happening and how it should be fixed as i cannot take it to the tech service until july even though it's still under warranty because i need it for school. ps: an external keyboard works fine.

Old PC with a Foxconn n15235 motherboard needs drivers! Help!!

So my Pc corrupted and I had to fresh install windows on it, but now its missing 3 drivers and one of them is for the Ethernet controller! I've tried searching everywhere for the windows 7 drivers but all I seem to find are some dodgey programs saying they will install it for me. Problem is without the ethernet driver I can't bloody connect to the internet. I've been using a USB to try get some drivers on there, but they just end up being useless programmes . I'm also a bit of a noob at these things, I don't understand where to find the names of things in my PC, I've opened it up but I don't understand whats significant and what isnt. If someone has the drivers and can teach me how to install them I'd be very appreciative! Submitted April 29, 2018 at 02:47PM by darrilsteady https://ift.tt/2r76xMZ
