    Hi Tony,

     

    Having read through this thread I can understand your frustration.

     

    Until my 2019 MacBook Pro died, I had my scratch drive on the internal SSD and I can't say that it was slow. Now that I'm using my older MacBook Pro and prior to moving to the Mac Mini, when it is finally delivered next week, i am back to using a cheap external ssd. Brian told me that the Read/write speed is unimportant, although  I am sure it must slow down the writing of all those JPEGs that go into the cache.

     

    Have you considered giving up on that particular external SSD and trying another one to create a new perfect browser cache from scratch as it were?

    PS. My scratch is a cheap 125GB Emtec brand I bought on Amazon. Its current R/W is only about 30-40, because it's connected to my monitor via USB-A. It can achieve ten times that with a USB-C port.

    Ray — The progress indicator is quite wonky now that there is just the one indicator for the top level folder being cataloged. My assumption is that while the catalog is still being constructed it is reporting the progress for the folder currently being processed and we have no way to know which folder that is. Once the catalog has been built it will show a consistent 100%.

    Tony — do you have another SSD or even an HD you can try using? There could be some kind of incompatibility with that particular drive. You may or may not want to continue using the drive if it works, the point is to test whether the problem is with the particular drive or not.

    Brian - while it's wonky it's probably better not to have it at all. Maybe suggest that during the next beta? I'd thought that I'd get a better indication by looking at the number of files in the WatchedContent folder (using the maths indicated above). But I was wrong.

    I had the same thought about drive incompatibility in Tony's case. These things do happen from time to time.

    On my previous system, a 2017 15" 16GB MacBook Pro I had a problem where about 50% of the time on the first launch of the day for Photo RAW my scratch SSD would automatically dismount itself from the computer to the point where the system didn't even recognize that the drive was sill connected to the system. I had to unplug it and plug it back in to recover. After that I wouldn't have any problems with it until the next random time it would choose to repeat the dismount. Only the 1st launch of the day. Of course the company could never reproduce the problem.

    I replaced the SSD, its enclosure, and the connecting cable one piece at a time. I tried all 4 ports on the laptop. Nothing solved the problem until I was forced to get a new computer. All of a sudden the problem went away with the same drive, enclosure, and cable I'd been using previously. There was something about that computer that was triggering the problem but only when launching Photo RAW. I haven't seen the problem since.

    Brian - I have a couple more questions for you, as someone who has moved to the Mini:

    1. My current internal SSD can't hold all my photos, nor can my 250GB external SSD, which I call "Photos and Docs" That holds the 38,000 images pre 2018 as well as my Documents folder etc.. The newer photos are on a Backup drive for the time being. I have bought a 1TB Samsung T7 to go with the Mini, and plan to put ALL my photos and docs on it. If I give it the same name as the current external drive, do you think it will recognise the current PBC that resides on the scratch drive? I wouldn't have both drives connected at the same time of course!

    2. Thinking of strategies to move to the Mini: I will clean install the OS on it rather than using the migration tool (largely because my MBP 2019 is a brick). So install PR 2022 afresh on it then restore from the latest backup taken from my MBP 2017?

    1) I'm not sure. I don't know if the program uses the path name or a hardware specific ID to identify the drive. If it is just the path name it should work just fine. If it is recognized you should be able to just pick up and go once everything is in place.

    2) You don't want to do a clean install of the OS. It's more trouble than it will be worth and more difficult than it used to be. Also, with the new security features and how the computer actually boots up (it isn't from the OS System Folder you installed!) it isn't necessary.

    When you get the Mini go ahead and start it up and set up your primary user account like normal. It needs to be the 1st account you set up and it must match the account on your previous machine or you'll wind up with ownership problems later. Once again, there is a UID number that is the actual owner of your files, not your user account name. You need all that stuff to match.

    You don't have to set up iCloud, or any of that kind of thing yet. You just want to be able to log on with the proper user account and connect to the internet for the next step which is to update the OS. You'll then have a clean computer with just the most current OS version to work with.

    Next, install your software. Finally you can get your user data onto it however you like. I used the migration tool with my CCC backup to migrate just my user data. With my external drives already in place that was all I needed to get back to a useable system.

    I use the Migration Assistant rather than manually copying things because I have made some customizations to my Home folder that override Apple's normal and protected file structure. I replaced their Documents and Pictures folders with symlinks to my external SSD where I keep that stuff. Migration put those changes back into place for me rather than my having to jump through the hoops needed to do it manually. The migration also  In the Finder it is an invisible change, everything works as it should. However, Photo RAW does not follow links or aliases so it was already set up to point to the external drive.

    Thanks Brian

     

    I am familiar with using the migration tool etc., as I moved from the MBP 2017 to 2019 only last year. Now the latter is not worth repairing, it's not practical to run the tool on the 2017 model as it's out of date in so many respects. I just plan to boot up the Mini and then install all my 3rd party apps one by one. I guess that's what I meant by clean install. And that's why I was asking abut whether I should use the restore function in PhotoRaw.

    Yes, the Restore function will move all your Photo RAW 2022 user data to the new system. That's all the stuff in ~/Library/Application Support/ON1

    By the way, I have asked Support what happens if one moves catalogued folders to a different drive. I will report back in due course.

    Hi Brian -  following your suggestion - I tried a Kingston 60GB thumb drive and thought I would re-format to make a clean start. I get this error when attempting to install APFS:  So then I tried formatting to Mac extended OS Journaled and the formatting works.  So then I open up PR and try to move PBC and still get the same original error.  The Samsung T5 1TB is the same!  Googling Apple stuff eg. https://discussions.apple.com/thread/253320101 - there are some real concerns with Disk Utility and ext SSD when the OS is Monterey.  Sadly, my iMac and 2 MacBooks are all upgraded to Monterey.  So right now, I believe this is an Apple problem.

    Instead of reformatting the Kingston Scratch 60GB volume, try reformatting the device itself. Select the Kingston Data… entry and try that.

    I just tried a couple of my thumb drives and the first one wouldn't even let me choose APFS. It was a small 8GB drive. The next one I tried was a 16GB drive and I was able to reformat it without any problems.

    I'll have to dig into the Apple thread you posted, thanks. I hadn't heard of any problems in this area yet. I subscribe to Howard Oakley's Eclectic Light Co blog and he hasn't said anything about it and he has done extensive testing on formatting them and installing bootable copies of the OS on them. This last week he's been writing about known problems with Monterey and formatting SSD's hasn't come up so I'll have to do some research on this once I'm more fully awake.

    Ok - I first formatted the device OS Journaled Guid:  Success!

     

      I then tried erasing and formatting to APFS Guid as below:

     Not sure  where to go now.....!  Ug!  Tony.

    You formatted the device for HFS+. An HFS+ formatted device cannot contain an APFS volume. The entire things needs to be APFS.

    I understand but clicking on device to be formatted as APFS auto creates HFS+ I've tried every option but everything fails.......

    If

     

     

     

     

    If it's a thumb drive connecting presumably by USB-A does it really matter if it's not formatted to AFPS?

    Yes. APFS is designed and optimized for SSD storage, HFS+ is optimized for spinning platters. The way the space is allocated makes a difference in both performance and wear and tear on the device.

    I don't understand why it won't let you format APFS. Are you using the Erase or Partition function in Disk Utility? Either way you should be able to tell it to use APFS.

    Does Photo RAW recognize it when HFS+ formatted? That's the most important thing we are trying to accomplish here.

    Have tried Partitioning but no joy.  Have gone down the route of HFS+ and attempting to move PBC produces the same old error....  I give up and may be you should also...... deep regret and spitting teeth!

    Thanks for your dedication Brian - I can only hope that when 2022.1 is released next week that may resolve the issue.  I wish I could take a MacBook back to Big Sur but I don't think that's possible,,,,,

    It is possible if you can still find the Big Sur installer. There are tips on the Eclectic Light Company. I'm going to let you dig through the pile of info if you're interested. https://eclecticlight.co/mac-problem-solving/

    Another option is to take the laptop and drive to your local Apple service provider, if you have one close by, and let them do it for you or tell you why it isn't possible.

    As suspected, Stevie in Support has just messaged me to say that it's not possible to move the PBC from one drive to another. So I'll have to start afresh if and when I get the Mini. It's Been in Louisville Kentucky since Last Thursday Would You Believe?

     

    Good luck Tony, with your issues.
