Photoshop: Can't see all available disks for scratch disks

Bug in UI....Photoshop Preferences > Scratch disksThis shows 7 disks... can't see others, even if they exist. The little up/down arrows can move disks so you can wiggle your way into seeing other disks, but this is really poor UI design to me.Seems like there should be a scroll bar on the right allowing me to scroll down to other disks. There are 8 more connected drives which are completely hidden by this UI. Mac OS10.10.3 / Photoshop CC2014 20141204.r.310 x64 (Why doesn't the "About" window stay open when switching back and forth with Safari to post this, for heaven's sake!)

I'm having a similar problem in PS 2015.5.  Photoshop isn't seeing all of my available disks.  Most importantly the SSD that I use as a scratch.

Is the issue only with SSD and SD storage?

I believe Photoshop filters out drives that aren't good candidates for Scratch Disks: removable media (SD cards) and drives mounted from network. There may also be a max # we can display at time. How many drives do you have mounted, and how many can you see as mounted?

iMatt - how is the SSD drive mounted? Is it connected to the internal bus? USB? Thunderbolt?

The SSD drive is internally installed on my 12 core silver Mac Pro. Photoshop is also only seeing one partition of a connected USB drive, and not seeing another non-SSD internal drive.  I'm running OS X 10.10.1

How many drives/partition total do you have mounted in the Finder? How many can you see listed in Photoshop's scratch disk pref? It can only display 7, presently.

I usually have 6, 4 internal drives, and one external with two partitions.  If you look at my screen grab above however, it isn't populating the whole list.

So a total of 7 total partitions mounted?

Very strange. And the drives are all formatted the same? Same user permissions?

All of them are  Mac OS Extended (Journaled), with Read/Write permission.

nope. I'm have the same issue with PS 2020. It doesn't see anything but the startup drive. I have 2 other slaves, not ssd or sd.

Hey Kristen!  Try this:  Open Photoshop, open any file and then save that file on the drive you wish to use as a scratch disk.  Now go into your preferences and see if the drive now shows up as an available scratch disk.

Since this is getting some activity.. :)

My experience (just tested in 20160603.r.88 x64) -- All the disc ARE listed. The problem is that "well" in the UI. If you highlight the bottom disc you see.. then click the down arrow, it will move down the list... bringing the disk below it up one (and you'll see it).

It's not that the disks aren't listed... it's just that you can't SEE them.

Just need a scroll bar on the right (where there appears to be a space for it).

(Note the disk titled "01" in the animation is an SSD and there's no trouble seeing it. And everything is formatted HFS+ Journaled).

Thanks for your response, that doesn't seem to be my problem.  I don't have enough disks to fill the list.  It's definitely not seeing some of my disks.

Sorry to hear that. I've got I think 11 various partitions and drives and have never had an issue with them being available, just had issues seeing them in the UI window. I assume you've checked the drives via Disk Utility to ensure they are all okay.

OK. Not the normal things that would preclude them from loading. I'll need to check with some other folks on the eng team for more ideas.

I was able to gain access to the solid state drive by ticking "Ignore Ownership on this volume".  Thanks for the link!

This thread is old but I got hope! I'm having a similar problem, I have connected a Toshiba External Hardrive, 2TB, and even though my mac is acknowledging the harddrive, my photoshop preferences only show the default CPU drive, and not the connected external drive. I'd love to be able to swap scratch disks but photoshop doesn't seem to agree. Also Im using CC 2019 on a 5year old Macbook Pro

For what it's worth, I held down Ctrl-Alt keys while launching and choosing disks was a very simple process.

Thats  all very well and yes it  is a Simple process, But in my own case One  day three external drives  were  recognised  as  scratch disks, one  day later, mysteriously after an adobe Cloud update  for photoshop etc etc, NO EXTERNAL DRIVES CAN BE SEEN with or without a  Ctrl alt, which ive use before to assign them . Im Mystified  ! the drives a re  working, but now not being seen to access  for  Scratch disks  ?...totally baffled here

I have the same issue. I have a Toshiba external drive that works perfectly fine on my iMac, however Photoshop does not show it as an option for a scratch disk. Does anyone have any  solution?

A little frustrating. I have 1 x TB seagate and a 128 GB Toshiba.
The seagate was recognised and came up, however the toshiba did not. So I ran the PS as administrator like mentioned in the other link and that did not fix the toshiba issue.  I am no tech person and dont feel comfortable messing with permissions I don't know anything about. So if anyone has a solution and willing to guide me through the process? Please can you share with me as my 1 TB packed up and I am currently using Toshiba.

I had the same issue.  It was resolved by opening any file in Photoshop then saving it on the disk not shown in the scratch disk preference window. 

Once you do that, Photoshop should recognize that disk.  So crazy simple!  :)

Hi Sasha - thanks for this - after I had spent ages trying to reformat the external SSD in different ways, with no effect and finding the technical guides on disk utility settings unhelpful, I found this posting of yours - and it worked perfectly.

Thank you so much!!

If you would like to get in touch - there may be helpful ways I could share my knowledge with you.

Kind regards,

Hedley

I THINK I MAY HAVE CRACKED THE  PROBLEM !  

HI Guys  Im new here...

I came  looking for a  Solution to the problem above, re  suddenly missing drives But im wondering if i may have just found one  for you all about  ten minutes ago partly by accident 

I had  four  Smaller  Drives, 3 Samsung SSDS used as file  back up, and  the spare  drive space  for the  Photoshop Scratch Disks,

 it  was  working fine til yesterday, July 28th 2020 

So on having the issues  above, I'd  been tearing my remaining follicles out trying to resolve this...

The Ctrl Alt  solution didnt work ...:-( 

So, i went  through the  drives one by one  ....

i was now  resigned  to having to make a  techy call or  more in depth problem query searching via  google .....

meantime i ws  looking for  a different set of images, to re  edit and noticed the One  drive  had a  huge  40 gig plus  series of tmp files  for photoshop ...

So naturally i deleted  these ....

I have  something i need  to do ,

a book cover etc for someones i know release in september ....and thought ok, lets Load photoshop anyway and  check the now  60 layer image out an se if i can continue  .

Out of  hope, an against the odds  , to my great joy , something miraculous had occurred,

I pressed  CTRL ALT  as  before 

THIS  TIME  THE  SCRATCH DISK OPTION HAS  RE APPEARED  FOR ALL THE USUAL DRIVES 

So this may be  the solution to our problems ! 

Go to each of your  external drives, and look for any Photoshop tmp files, and  delete them 

This  seems to me the only thing that can have affected the now  working Scratch disk preference gain 

The machine  has not been rebooted either..Just the tmps gotten rid of an adobe  reloaded.....

Really hope this helps

Cheers All
STAY SAFE BE WELL under  COVID

I found a fix for my HP laptop: 118G SSD C drive, 2 TB D drive,' Photoshop Scratch Drive Full': I had worked on it for hours, tried holding down ctrl + Alt at PS start many, many times; D drive never showed up. Then an idea: hold down shift + Ctrl+ Alt when starting PS, Wallah, D drive showed up with 1.=05 TB, and I deselected the full C drive scratch drive. Plenty of room now!.
