the health went from %69 to %72 then to % 71 back to %72

but me other 500 gig f3 HD502HJ ITS Health is %85 ?

Many authors of SMART software misinterpret the attribute data. For example, HD Tune's author appears not to understand the importance of the uppermost 16 bits of the 48-bit raw values. You will also occasionally see nonsensical negative numbers for read and write counts. In your particular case, the author is paranoid about spinup times. Samsung doesn't help by using counterintuitive normalised values. Normally one would expect that 100 would be the target for a "perfect" drive, but after looking at other SMART reports for your model (see below), I've come to the conclusion that the following formula applies:

normalised value = 100 - ((raw value - 800) / 300)

The raw value appears to represent the spinup time in milliseconds.

A value of 100 equates to an unrealistic spinup time of 800 msec.

The loss of each point equates to an increase in spinup time of 300 ms.

Here are several forum threads with SMART data for your model:

Here are some numbers I've collated, many for new drives.

51 15430
63 11900
63 11850
71 9490
72 9260
72 9260
76 7910
77 7840
78 7400

Therefore, on the basis of the SMART report, it would appear that your drive is perfectly healthy. However, the dip in the preformance graph suggests that there may be a bad patch in the media, although the dip may also be due to other processes interfering with the test.

There's no bad patch in media. It's normal in these samsungs to have SMART triggered and eventually reset like the drive "fixed" itself. I can't tell you more.

I think all these "drive monitors" are useful like a tit on a bull, the unique way to tell about the health of the drive is to monitor some INTERNAL info, that luckily are unaccessible to end user. SMART can give a quick idea and for something can be useful, but give also a lot of false alarms if mis-interpreted by SW and end user.

thank you for all the help guys a think a can rest easy now that me data safe

If you want to be 100% sure never trust a disk and a single backup, better two Drives can fail anytime anywhere.
For somemore peace of mind, a simple scan with MHDD can pinpoint eventual grown defects (assuming the drive was not bumped or suffered from power cut during write). Samsungs from P80 on have an excellent reallocation of grown defects.
IF the problem is more physical than CRC-related something more is needed.

P.S. be careful using programs to scan surface : always in NON DESTRUCTIVE MODE (nothing should be written on disk) or you will loose data for sure... (never enough said!)
