macos – Easy shell instructions by no means end, however solely on exterior drive

More often than not, my Mac’s Terminal works nice. Nonetheless, after I use it to navigate the file system of my WD My Passport 1TB exterior drive, it… nearly works. Virtually. Easy instructions like cd and ls work usually besides that they do not seem to complete — they depart the Terminal ready on the final line of the ls outcomes, slightly than presenting the immediate. Successfully, I’ve to ^C after each single command (and I higher hope it was truly completed after I do this).

• It is a 2020 Intel Macbook Professional, 13″ show, operating Sonoma 14.4.1. The shell is zsh.
• I have not tried ready greater than a minute or so, on the idea that it actually should not take that lengthy for an ls.
• It is solely the WD 1TB drive that does it. Searching recordsdata works usually* on my little SanDisk thumb drive and the Seagate exterior drive that I exploit for Time Machine. (* The Time Machine drive will not run ls, however that seems to be a Time Machine factor, and the “operation not permitted” error reveals up promptly earlier than going again to the conventional immediate.)
• Some instructions work usually — tar -xzvf on a 53GB tarball simply completed and exited to the immediate. man tar didn’t, nor did much less or a easy sed.

Why is that this occurring? Why is it solely the one drive that does it?

edit: Extra data as requested in feedback.

• The issue drive is formatted ExFAT. The thumb drive is FAT32, the Time Machine drive is Mac OS Prolonged (Journaled), and the laptop computer’s built-in SSD is APFS.
• The issue disappears after I use a easy immediate (PS1="$ "). The issue immediate is "(base) [%T] %n @ %1~$(git_prompt_info) »", the place git_prompt_info is a perform outlined in ~/.oh-my-zsh/lib/git.zsh :

# Outputs present department information in immediate format
perform git_prompt_info() {
  native ref
  if [[ "$(command git config --get oh-my-zsh.hide-status 2>/dev/null)" != "1" ]]; then
    ref=$(command git symbolic-ref HEAD 2> /dev/null) || 
    ref=$(command git rev-parse --short HEAD 2> /dev/null) || return 0
    echo "$ZSH_THEME_GIT_PROMPT_PREFIX${ref#refs/heads/}$(parse_git_dirty)$ZSH_THEME_GIT_PROMPT_SUFFIX"
  fi
}

Any thought why which may trigger issues solely on the one drive — or, failing that, a means to make use of a unique immediate solely when that perform hangs up? (I do like having the department in my immediate and would love to provide that perform some option to deal with no matter error is occurring right here.)
