mac data rescue unmounted internal partition

If you can install & boot macOS from an external drive you can use DriveDX to check the health of the drive. I suspect you may have a failing hard drive or a corrupt APFS file system (or both). Contact a professional data recovery service such as Drive Savers or Ontrack both provide free estimates are recommended by Apple.Install macOS to an external USB drive so you can boot the laptop from the external drive.

Remove the hard drive and connect it to another Mac using a USB to SATA Adapter, drive dock, or enclosure.Put laptop into Target Disk Mode so you can connect the laptop to another Mac.If you need to recover files from the internal drive, then you have several options. I think I will need to get a new MacBook but hoping one of the geniuses on this forum might have a solution to saving the old woke! Many thanks in advance. I am not able to get to an Apple Store for the next few weeks. Should I try and create a partition on the Base System? Or a new disk image? I have an even older Mac using 10.6 if that is of help (ie I could create an image on the La Cie HD to boot if that made sense though the La Cie HD has my TimeMachine backups). Because I have a recent back up I just need to erase and reinstall but the erase is the problem. The Base System shows 1.19 GB with a little spare space. I have done all the Google searches for the problem and have not found a solution. Once a few days ago the HD appeared briefly in Disk Utility (!) and I tried to erase but an error message appeared and I have not seen it since. Disk Utility only shows disk0 and the ex dented Mac OS X Base System. The crux is that no disk is available when trying to reinstall. Have timemachine backups from an external HD, can access the internet etc. I have booted (successfully) countless times in recovery mode. I am trying to reinstall Mountain Lion on a 2014 MacBook Air that has crashed. I'm stuck - please, help! I'm starting to wonder if maybe the problem isn't the drive but something else, like the cable that connects to the HDD? Or maybe Western Digital just tried to fix my faulty drive, instead of replacing it, but failed and I still need a brand new one?Ĭannot reinstall Mountain Lion on MacBook in recovery mode: Only Mac OS X Base system available in recovery mode. I've found other work-arounds to erase a drive, but they don't work for a brand new drive because I can't get to the Terminal app, for example. I can't install the OS because it doesn't recognize the new internal drive (because I failed to set it up in Disk Utility, I think) and I can't restore it from a Time Machine backup for the same reason. I tried to follow some tutorials to set it up, but when I get to Disk Utility, it fails to erase the new drive. A few weeks ago, that drive died so they sent me a new replacement under warranty. A year and a half ago, the hard drive died so I replaced it with a Western Digital 1TB HDD. I have a mid-2010 13-inch Macbook Pro (I know it's old, I'm just trying to make it work until I can upgrade). Is there a way for me to erase everything on the HD and start from scratch? Or is the internal HD completely toast?įailing to install a new hard drive Hello, I have a lot of my pictures stored on another external, which is my main concern.

So, am I just out of luck at this point? Is everything lost? I don’t really want to take it anywhere to have satay retrieved because I don’t want to spend the money on that. I bought a new external hard drive hoping I could somehow get my data onto it, but idk if that will even be possible. I don’t have a backup on Time Machine or any other hard drive. The recovery HD is the only one available and it is grayed our and says it is locked. Even if I try to install Lion, it won’t allow me to select a hard drive to install to. I messed around trying some commands in Terminal as well and that did nothing.

I’ve tried verifying it, repairing it, and mounting it through disk utility to no avail. It is showing on the left bar but it is grayed out. Naturally I wasn’t sure why, so I did some searching online and ended up getting into Disk Utility and notice my HD is no longer mounted. Recently I booted up my 2011 MacBook Pro and it started up with a screen to install OS X Lion.
