I have two brand new Ultra Flair drives that are acting very strange. They are said to get warm with sustained writing operations, these two drives get beyond warm, they get HOT, real hot. So hot that they fail and crash. The write operation fails, Error Copying File & a Second error sceeen Device I/O Error on the Flash Drive Directory not accessible.
This happens with both drives on both USB 2.0 and also USB 3.0 ports or when connected to a USB 2.0/3.0 Hub. The drive functions normally for the first 2 mins then overheats and crashes, only during writing operations only.
This also occured when trying to encrypt the drive in Wiundows 10. The drives would encrypt normally for ~28% then overheat, crash, Windows would disable the device so that even when it was ejected and allowed to cool it was flagged and would not function again without rebooting windows. When the drive was reinserted after reboot, the encryption would start again where it left off.
The drive becomes too hot to handle with bare hands and needs to be allowed to cool for atleast a minute or risk first degree burn to your fingers.
I even went as far as to try freeze spray on the drive case to try and prevent the overheat and crash without any success.
Has anyone else had a simular experience?
I plan on returning these to the vendor I purchased them from.

The drives were empty and being prepared to be used later.

Was just browsing for answers on this. I have the Ultra Fliar 128GB myself and I've been running into this same problem trying to write 60GB of data at once to the drive. Several of SanDisk's 3.0 drives get super hot. I also had an Ultra Fit that did the same thing.

I just measured the temp on the backside of my 128GB ultra flair drive with a thermal leak detector. It registered 138-139 deg F, which explains why it is painful to touch more than a couple of seconds.
