BIOS not detecting SSD (sometimes)

[cesedy]

Hi.

I have a SSD Lite-On CV3-SD256 from Lenovo ideapad 300-15ISK laptop.

The problem is that sometimes it is not detected in BIOS.

After a Google search I found out that CV3 models have this problem and need a firmware update (quote from Dell website):

CV3 Series Drive Not Detected

Some LiteOn CV3 series Solid-State Drives (SSD’s) have been found to have a BIT Flip issue (an unintentional data state switch from 0 to 1, or 1 to 0, of a bit stored to random access memory) that causes the NAND Flash memory of the solid-state drive to become corrupt and the drive to no longer be detected by the system.

 

 

Dell and Lenovo webistes provide the firmware updates for these CV3 firmwares:

CV3-8D128        T872205
CV3-CE128        TC72205
CV3-8D256        T887905
CV3-CE256        TC87905
CV3-CE512        TC97905
CV3-8D512        T897905
CV3-SD128        TS72202

So, there is a firmware update for SD128 model but not for a SD256 model.

Where could I get a firmware update for SD256 model?

 

Thank you.

Would this help?

Seems to be the same firmware for all the affected drives

Yes, I already tried them. None of them detect my drives firmware as upgradeable.
