Question HDTune gives SMART error, Crystaldisk & Speedfan does not...

(update: the hard drive in question seems to be operating as normal now. Still very curious as to why HDTune would give off the warning while the others don't ???)

this is weird, at least i havent seen it.

i have a 4TB external hard drive that is connected via eSATA
today i noticed it was taking forever to load the contents of a folder (albeit a really really really large folder)
but loading the contents of the folder took MUCH longer than it usually takes.
however smaller folders still loaded quickly.

So because of the drive appearing to stall out...
I loaded up HDTune and look at "Health"
HDTune says "warning" for my drive health.
I am getting an error on Ultra DMA CRC Error Count - the Data result is 33 (number of interface communication errors)

Tried new cable, no difference.
Tried swapping eSATA ports, no difference.
So at this point i'm thinking this must be a motherboard issue, right?

To verify, i plug in a USB cable into my external HD instead of the SATA, and try it on my tower again.
Same error from HDTune. Same number every time: 33

So last resort, I take that USB and plug it into my laptop.
Load up HDTune on my laptop.
Same result: 33

Totally mystified at this point, but I know it's not the cable, not the motherboard (that's a relief)
so the only thing left is bad sectors on my drive...

I load up Crystaldisk for a second opinion, it comes back 100% healthy
I just now tried Speedfan, 100% healthy, ran a short test, no error -
the Fitness bar and Performance bar both are only one block shy of the maximum.

I would just write this off as HDTune being weird, but today I did have that instance with my hard drive being super slow.

Can anybody make any sense out of this?
BTW all my other drives came back fine on HDTune and i have a tower with 4 other HD's in it.

PC Specs:
mb = Asus P5K-E
cpu = q9550
the HD in question is a Max Digital 4 TB, 64mb cache, 7200 rpm, sata 6.0/gb internal surveillance HD

Yup they all show it but only Hdtune is flagging it. Probably because there aren't any associated Failed or Reallocated sectors which means its not likely to be a disk issue but a data corruption of some sorts. Perhaps the PC locked up or powered off in the middle of a write, Bit-rot from the data not being refreshed, or something ...

can you help me understand where crystal and speedfan are showing it?

good to know this... i will have to do a sector scan... however i heard the WD util can cause data loss because it will attempt to automatically correct bad sectors

i have no idea if that is true

i still dont get it LOL but that's alright.

i guess the main thing now is if someone could give me a recommendation on a sector scanner. i read somewhere that the WD diagnostic could lead to data loss, because it attempts to fix the bad sectors as it finds them

Again, probably nothing to worry about> the number wont go down since it's a count of the number of times a checksum error in the data was detected, so as long as it doesn't increase then you're ok.
