Could "Too much" blueSCSI data/drives/apps slowing down my Mac Plus?

I have a MacPlus. It has a BlueSCSI v1.

It's worked great but I've noticed it's a few symptoms and I'm not sure the cause. I'm not assuming it's blueSCSI's 'fault' so don't get me wrong!

I mainly use it just for keeping a diary in WriteNow. So 95% of my use is I just double click on the writeNow saved file, type some, and put it away.

Roughly half the time I double-click that saved WriteNow file it makes like it's launching WriteNow (i.e. menubar goes blank like with any new app launch) but then I immediately get a finder alert dialog box saying something along the lines of "the document could not be opened because the application that created it.." etc.

(Of course now that I want it to happen I can't reproduce the issue.)

At this point - if I press "OK" and then simply again double-click the document, WriteNow launches successfully no problem and opens the document as expected.


Ok -- but there are other issues too. If I try to launch various era-appropriate applications (mainly games from 1984-1987) they won't start or they take a >long< time to start (like 2-4 minutes where it's hanging in application launch till finally it goes). Arkanoid is an example of a game that refuses to launch on my Plus but runs totally fine on my 68000-based Macintosh SE with the same 4MB of RAM on the same System 6.0.8 but it starts instantly on it. Sure the SE is not 100% same as a Plus but given the same system, RAM, and of course CPU, I'd expect launching a game would work and take similar time to launch on both systems.



I'm wondering if this isn't something to do with the desktop file (as in the 'rebuild the desktop file' file) and maybe having hundreds of applications on multiple volumes each of a few gigs isn't like 'way too much' for the machine somehow? I'll admit I haven't tried using the exact blueSCSI with the exact same SD card that gives me trouble on the Plus over on the SE (call me lazy, but the SE is upstairs in a macbag and has the internal blueSCSI v2 while the Plus has the external blueSCSI v1 so for an apples to apples (har har) comparison I'd need to open the SE up and remove the internal blueSCSI).

Things I'd start with:

Make a backup of the image! (always a good idea anyways)
Follow the troubleshooting guide, especially re-formatting the SD card with SD Card Formatter - full overwrite.
Verify your drivers are the Apple ones (Disk Jockey can inspect and fix this for you)
If you have multiple drives make sure they are all using the same driver.
Try a fresh image - smaller size (say just 100mb) and just put the system and app on it and try to reproduce
Does this happen in an emulator? Use my Mini vMac fork or Infinite Mac (eliminate the machine or the bluescsi)
Keep trying to eliminate variables.

Each volume has its own desktop file. Have you rebuilt all of them? (I assume yes)

(From memory) 6.0.8 has a volume size limit of 2GB, you mentioned “multiple gigs” of data, I assume each individual volume is below the 2GB limit?
