I run Parallels on an iMac and have reliability issues with USB sticks.
I need to copy files to and from the USB stick so as to use them on my Toshiba Ultrabook running Windows.
I find that it works well for a while then over time either Mac OS or Windows on the Mac won’t recognise the disk or else will start running extremely slowly in Windows Explorer.
As a result I have replaced quite a few USB disks and eventually ended up in the same position.
Recently I bought a SanDisk USB disk from a Mac shop, I then copied files on to it in Windows Explorer under Parallels, put it into my Toshiba, copied some files back and forth, and when I put the USB back into the Mac , Windows (under Parallels) would not recognise it as it had just already done.
Usually I find when putting USB sticks into the Mac the system will ask me if I want to connect it under Mac OS or under Windows and previously I found that choosing Mac gave me access under both anyway.
With this new USB the only way to get it to be recognised under Windows was to choose Windows when connecting then I could read it in Window Explorer, but not in Mac OS of course.
Has anyone any ideas please?
The change in behaviour over time (recognising, then not recognising, and/or slowing right down) is a great frustration.
Thankyou for your assistance.
