Lenovo B50-30 3.5 Harddrive not seen

Hey Everyone

First let me say I have not seen this before...I have a All in one b 50-30 that does not see the 3.5 inch Hard drive.  So I put another 3.5 in and it is not seen.  So I replace the cable harness still no drive so by chance I hook up a 2.5inch Laptop drive and I can see that one.  Every 3.5 drive is not seen every 2.5 drive is seen...$!!$#@% any ideas?  And by the way the cdrom drive is seen.

Hi ctohelpsu , 

 

 

Greetings. 

 

Are those 3.5 HDD you tried working on a different pc or at least detected in the BIOS ?

Would we be able to isolate both power and data cables used in working condition ?

 

Try to turn off and unplug from the power port and press down power to drain .

Turn on and tap F1 again fro BIOS and load defaults F9 then save and exit . 

Check if BIOS would be able to check HDD ?

 

Update us how that would so we can isolate the point of failures. 

 

 

Regards

Yes those are working HD's.  I changed the motherboard and it worked as expected.

Hi ctohelpsu , 

 

Greetings. 

 

As we try to isolate the motherboard as the point of failure , you can try flashing the BIOS from the support site as an option. 

 

Hope that would help.

 

Regards
