The drive just gets ejected when the laptop goes into sleep mode, even when it’s in use, resulting in read & write errors as the device cannot be found.
When the laptop wakes up the drive immediately reconnects and works normally but I cannot leave the drive doing any kind of work overnight due to the disconnects.
I’ve tried all kinds of power settings - USB always on, never turn off drive, USB root hub power management, etc. Nothing works, and it always disconnects when I leave it overnight and it does so regardless of the USB port it’s connected to (laptop or usb hub).
I use a lot of external HDD drives (WD Passport, WD_Black, Seagate Expansion Portable), all 2.5" without power supply, and they all work properly, I’ve never had a drive disconnect when in use.
The SanDisk Extreme Portable SSD V2 2TB may disconnect when a laptop sleeps due to power-saving settings that disable USB ports during sleep mode. Adjusting the power settings or using a powered USB hub may help prevent the disconnection issue.
I lost some files recently, but luckily I reached out to EaseUS and they assisted me in retrieving my lost folders. I learned the importance of always having a backup on a different brand device. SanDisk Extreme SSD Failure: Tips to Prevent from Further Damage
Unfortunately I’ve had to return my Sandisk extreme portable SSDs because if I want to rely on transferring a high volume of files overnight, it will just run very hot and disconnect by itself typically after 2 hours. I also have the Samsung T7 and Crucial X9 pro which work without a problem on the same tasks. The sandisk portable looks very pretty, but really I don’t want to have to fiddle about with settings on my laptop to get it to work reliably.
