Hi list,
I’ve booted up my Dell laptop using a USB flash drive with GRML on it. However, I cannot see any block devices for the hard drive partitions. The only sdX devices I can see are sda1 and sda2, both for the bootable USB drive itself. To be clear, lsblk -a doesn’t show any other sdX devices than sda.
I would appreciate any tips regarding how I can make GRML see these partitions since I would like to make backups of them using gparted.
Thanks,

I would guess that if "lsblk -a" shows no other devices, then "fdisk -l" will also show no other devices. It *might* be worth trying "dmesg | grep sdb" just in case that device appeared then disappeared since the kernel started. If all these commands produce "nil returns", then as far as the kernel is concerned, these additional devices do not exist.
Did you change anything in the bios in order to be able to boot grml? (such as "hiding" any hard disks?)
Also, are you sure that if you remove the grml usb stick, you can boot from (or at least make reappear) your hard disk?
If all of the above fails, it might be time to remove the disk from the laptop and plug it into an external usb-pata or usb-sata adapter/converter (that's what I normally do anyway!)
HTH, Jaime
Hi Jaime,
Thanks for the tips. I'll try them tonight.
Med vänlig hälsning David Renström

If you are using an NVMe SSD drive, you will find /dev/nvme* devices (sorry, I don't have a Linux machine handy with NVMe, my memory may be off).

Hi,
I've tried all your suggestions now and this is what I've found:
- No NVMe devices. - lsblk -a and fdisk -l don't show any other disks than the USB memory containing the live distribution. - dmesg | grep sdb doesn't show any devices being mounted. - Yes, Windows 10 boots up fine on the SSD drive. - No disks have been hidden in the BIOS settings. It's now booting using UEFI mode.
What else can I try?
Thanks, /David R.

You could try "find /dev/disk" and look at all the files you can find that way. Maybe one of the devices is what you are looking for.

Hi,
Thanks for the tip. In the /dev/disk directory I can only find the same partitions I've already found, i.e. the same as /dev/sda1 and /dev/sda2 which both belong to the USB thumbdrive. So another dead-end.

Hmmm. Strange. I'll admit that I've never seen anything like this before.
Could you please let us know the laptop model number/type, hard drive model/type, and attach/include the output of something like "lshw -class disk -class storage -short" (I'm assuming that grml contains lshw, but I can't check that assumption right now).
Hi,
Laptop model: Dell Latitude 5510 Hard drive model: BC511 NVMe SK hynix 512GB
The output of lshw is as follows:
H/W path Device Class Description ============================================================== /0/100/14/0/4 scsi0 storage USB Flash Disk /0/100/14/0/4/0.0.0 /dev/sda disk 16GB USB Flash Disk /0/100/14/0/4/0.0.0/0 /dev/sda disk 16GB /0/100/17 storage
Thanks, /David R.

Ok. Given that this is a "can't see nvme"-style problem, I've found:
https://www.reddit.com/r/archlinux/comments/9whkz8/cant_see_nvme_on_new_lapt...
https://www.reddit.com/r/tails/comments/j1wzr6/disk_manager_cant_see_my_inte...
https://forums.linuxmint.com/viewtopic.php?f=46&t=321939 ("Linux Mint installer cannot find nvme drive on Dell XPS 15 laptop")
so one thing is certain: you are not alone! There appear to be 2 lines of approach: either changing bios settings for the storage controller, or changing kernel boot parameters (such as "nvme_core.default_ps_max_latency_us=0"). Although I consider changing bios settings to be safe (it *should* not damage your existing data), if you are unhappy doing so, there is always another "safer" option: remove the drive and access it using an external nvme-usb adapter. It's your call.
HTH, J :-)

Additionally it might be worth testing with a current Grml daily ISO (see https://grml.org/daily/), which provides a more current kernel version than the latest stable Grml release. (I didn't find any information about the Grml release that's in usage here, so I assume we're talking about the latest stable Grml release. :))

I also want to point your attention towards https://lore.kernel.org/linux-pci/20190620061038.GA20564@lst.de/T/, quoting from there:
| Many current and upcoming consumer products ship with the AHCI | controller in this "RAID" or "Intel RST Premium with Intel Optane | System Acceleration" mode by default.
So look out for "Switch your BIOS from RAID to AHCI mode to use them" in your kernel messages (check `dmesg`).
Thanks to Chris Hofstaedtler for the pointer offlist.

Wow - that's a good find (and a desperately sad state of affairs if things have not improved since those emails were written). :-0

Yes, there is large agreement to disagree with "Some_one_else should do it" 8^)
