MacBook NVMe SSD Issue
I have a 2015 Macbook with an integrated 256gig SSD that has stopped working apparently due to the failing SSD. I've been able to boot into a live USB thumb drive in an attempt to try to get the failed drive to mount and hopefully recover some data using tools such as testdisk or ddrescue etc.
The MacBook seems to work fine within the Ubuntu live environment with the exception of the SSD not being properly detected or mounted. The output for dmesg shows the following:
Strangely however lspci seems to show the device being detected properly:Code:[14329.580522] nvme nvme0: pci function 0000:03:00.0 [14329.580672] nvme nvme0: detected Apple NVMe controller, set queue depth=2 to work around controller resets [14345.130062] nvme nvme0: Device not ready; aborting initialisation [14345.130072] nvme nvme0: Removing after probe failure status: -19
lshw also seems to list the device however shows storage as "UNCLAIMED"Code:03:00.0 Mass storage controller [0180]: Apple Inc. PCI Express SSD [106b:2001] (rev 01)
I've tried assigning the device with "echo 106b 2001 > /sys/bus/pci/drivers/nvme/new_id" however get the following error:Code:*-pci:3 description: PCI bridge product: Wildcat Point-LP PCI Express Root Port #5 vendor: Intel Corporation physical id: 1c.4 bus info: pci@0000:00:1c.4 version: e3 width: 32 bits clock: 33MHz capabilities: pci pciexpress msi pm normal_decode bus_master cap_list configuration: driver=pcieport resources: irq:16 memory:c1500000-c15fffff *-storage UNCLAIMED description: Mass storage controller product: PCI Express SSD vendor: Apple Inc. physical id: 0 bus info: pci@0000:03:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: storage pm msi pciexpress cap_list configuration: latency=0 resources: memory:c1500000-c1501fff
Below is also the output for this device using lshw --short:Code:bash: echo: write error: File exists
Below is the output for lspci -vvxxxs 03:00.0:Code:H/W path Device Class Description ================================================================== /0/100/1c.4/0 storage PCI Express SSD
At this point I'm not sure if the device is truly not functioning properly (since it was not detected by macOS, or if there was some other kind of issue such as a corrupt partition etc. The device seems to be recongized by Ubuntu however I cannot get it to be detected properly or to mount.Code:03:00.0 Mass storage controller: Apple Inc.

I have some critical data on this device that I really need to try to access. Are there any additional steps I can take to troubleshoot this issue or try to get the device assigned and mounted? Any help would be greatly appreciated.
Thanks!
