SanDisk Extreme Portable SSD V2 2TB disconnects when laptop goes to sleep

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.

Any ideas how to solve this?

My laptop is Lenovo Yoga 7 15ITL5.

Hi @georg1,

Have you opened a Support Case? If not opened, for more information, please contact the SD Technical Support team for best assistance and troubleshooting:

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.
