Hello.

Is it supposed to take a long time for macOSes (updated Big Sur v11.x
and Mojave v10.4.6) to finally see an USB3 4 TB HDD's encrypted
partitions (macOS+Journaled and APFS)? ExFAT (no encryption) always
mount right away, but the other ones take like a minute or more to be
seen and ask me to enter their passwords to mount. This is with a month
old external Seagate HDD
(http://www.amazon.com/Seagate-Portable-External-Hard-Drive/dp/B07VS8QCXC/)
with three partitions (exFAT, encrypted macOS+Journaled, and encrypted
APFS -- http://imgur.com/a/DUFXWmK from macOS Mojave v10.4.6's Disk
Utilty v18 app when partitions are not mounted, partitioned, and
formatted).

Thank you for reading. :)

I have 4 USB 3, 6 TB disks attached most of the time. On a "wake from
sleep" they're available in seconds. On a re-boot or re-connect it can
take 10 - 20 seconds for all 4 to show in Finder[1]. They are all
encrypted drives. The "password" is stored in Keychain so there is no
entering of the password on each connect required.

(Catalina 10.15 ish.)

[1] IIRC even if the volume doesn't show in Finder quickly, I believe
they show in Disk Utility quicker than that - but I won't stand on it.

My guess would be the OS on booting/reconnecting is checking the disks,
which is doesn't do on waking. For large cpacity drives this can take a
bit longer than smaller capacity drives.

Disk Utility app also takes a long time to show them. :/

Part of me wonders if "disks take a long time to mount" is a possible symptom
of a failing drive. Do these drives have SMART capabilities? If you have a
SMART monitor or reporter, you can look at the drive error statistics and see
how many bad block replacements have been made (not indicative of an error,
typically) and how many uncorrectable bad block errors (which are a problem).

I've used SmartMonTools on other systems to do monitoring and it works well.

I am going to guess that you have not, however, created multiple
partitions on those drives like it's 1999.

Be careful what you wish for. You never know who will be listening.
Or what, for that matter.

According to SMARTReporter v3.1.17 b2295 (no newer version since
10/22/2018?), it only found the internal SSD in this 2012 MBP (Mojave
v10.14.6). :( I'm using
https://binaryfruit.com/download/mac/satsmartdriver/SATSMARTDriver-0.10.2.zip
to install the external driver for USB drive access (it took forever to
install too). :(

I also tried GSmartControl v1.1.3 (last updated in 11/12/2017!) in my
decade old, updated 64-bit W7 HPE SP1 PC. It also said no SMART for this
1.5 months old external HDD too.

I'm pretty sure I abandoned multiple partitions before 1999.
