Have you tried opening a different file in PS before attempting to eject your memory stick? That might work. If it does, it's a workaround, but you won't need to quit PS to continue working ...
Thanks for your suggestion. Unfortunately that hasn't solved the problem :-(
After you save your file go to Edit > Purge > All
And as a tip, you should always save your files locally and then copy them to external locations.
Thanks for your response.
However, when I go to Edit > Purge the All option is greyed out as all the other options except Video Cache.
I'll take up your tip though regarding saving files locally which I guess will eliminate this issue.
Ok, just realised you have to perform some adjustments to the file before the Edit > Purge > All option appears.
So, did this but the problem still exists.
For what it's worth, I have the same problem in PS and MS Word. My system sees the USB drive as being used even after the files are closed. I'm guessing it has something to do with the File history.
What's the percentage of memory usage allocated to Photoshop ? (See under Preferences / Performance)
Also, do you have any plugins installed ?
No plug ins installed and I have 64GB Ram with about 47GB allocated to PS (the default PS allocation).
The strange thing is this only started to happen today - before today everything was fine.
4.7 gb ? Cause if you really have 47gb that's overallocating, I don't see why you'd let PS use that much. What Photoshop does is reuse instead of releasing memory, so even if a file is closed its information is still stored and used, including the file location (that's why you can't change it by moving, renaming, ejecting etc.).
The solution DrStrik9 provided should however clear the allocated memory so it can be used on the new file, so after you save and close your file try the Purge method, then Open or Create a document and perform any random action so that the available memory is cleared and shifted on this new document. Inconvenient, I know, but I guess it's just how things work.
You can read more about this (including Adobe employee's comments) in this thread
Ok, I've just checked out the Photoshop/Preferences page and this is what is there under the memory usage section:
Available Ram = 59667MB
Ideal range = 32816-42960 MB
Let Photoshop Use = 42363 MB (71%)
This is what Photoshop has set up - I haven't played around with the settings.
I'll retry DrStrik9's solution since I didn't perform any action on the second file when I first tried his suggestion.
Still would like to know why it's only started to be an issue today after months of running ok and nothing has changed at all on my system?
Many thanks for taking the time to respond.
Most likely you haven't noticed it before. As part of my daily workflow I need to save files on a network drive and I always encounter this issue if I try to move or rename a file after I just saved it. Sometimes even after working on a new document Photoshop still locks the previous file and will only release it when I save a new one, however the Purge method has been working good for me.
I have this same problem, but I have noticed it's across all Adobe products, whether they have opened data on the USB drive or not.
Open After Effects
Insert USB drive to transfer FILES HAVING NOTHING TO DO WITH CURRENT ADOBE PROJECT. Not even any media files at all on the drive!
Click the "Safely Remove Hardware and Eject Media" command
Have Windows tell me that: Windows is unable to stop the device "USB Mass Storage Device"
The only solution I have found is to close all Adobe products and then the USB drive will take the eject command easily and instantly.
BUT... I'm still rendering an important file, and to stop and start everything again will take valuable client time... NOT GOOD!!
HELP! Any solutions??
Thanks in advance.
Adobe CC (All latest updates)
This all started before Windows 10, and a few versions of the Adobe products ago...
Try disabling "Save in Background" and maybe "Automatically Save Recovery Information Every:" in Preferences > File Handling > File Saving Options.
Thank you! This works for Photoshop, but not the other products. There isn't the same option in After Effects, Adobe Media Encoder, or Premiere. Any thoughts along those lines?
Not really familiar with those products. I believe Premiere has a similar settings, but not sure where it's at. Probably would be best to post something on those forums to get someone a bit more experienced with those products.
