I read that weak CMOS battery can prevent detection of a drive. I have
two
SSD drives. One an old Samsung 500GB boots reliably. Drive D: is a new
Seagate Barracuda, 500GB that is not detected reliably. I've done
everything
conceivable with the cables. I've read bad reviews on the Barracuda.

BIOS program says CMOS battery is 3V whereas 3.3V might have been when it
was new.

Is it worth my time to buy a new CMOS battery?

Thanks





Glad you got it figured out.

To answer your question though, a 3.0 volt CMOS battery is fine.

If the battery was too low, you'd simply lose your settings.

I did *once* have a battery around 2.6 volts that would not allow the
machine to post.

Thanks for your reply.

Unfortunately, no matter what fiddling I could do, the Seagate Barracuda
continued to show unreliable symptoms. Read/write errors and failure to
detect at boot up. I ran Seagate tools that said the drive was slow, at one
time. I read a bad review of Barracuda. We decided it's a bad drive. I have
a one year warranty. I bought a 3 TB WD HDD and installed it. I am now doing
a backup. Then I will return the drive for a replacement Barracuda SSD.

SSD drives are very nice for instantaneous response, when they work.

I plan to run some large programs for medical imaging. When it comes to
medical diagnostic imaging, one needs to do it oneself.
