From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My user account doesnt have sudo despite being in sudoers. I cant run new commands i have to execute the binary. Grub takes very long to load with "welcome to grub" message. I just wanted a stable distro as arch broke and currupted my external ssd

Probably so, but just to be certain about the partition table not causing it, I'd maybe try running the dd command on /dev/sdd rather than /dev/sdd1. It should be able to read a little more than the attempt to read /dev/sdd1 did. I'm not absolutely certain what happens if a partition table is invalid and has a partition that includes a region extending off the end of the hard drive, and I haven't actually seen a dump of the partition table posted by OP. It might be that an attempt to read a partition that extends off the end of the drive gets exposed to an application as an I/O error.

I'm also a little surprised by the lack of kernel log messages. Maybe things have changed, but with all of IDE and SATA internal drives, I always got errors logged with the kernel if I/O failed on a drive, and they always referenced the drive's device name.

I just can't think of much higher level stuff that would cause I/O errors while trying to read at a partition level, though.

And a failing drive could also explain the freeze in Arch, the slow booting of Debian, the inability to mount the drive, and the I/O errors, so it'd explain a lot.
