CrystalDiskInfo 40mil Reallocated Sectors Count?

[Slackar]

I've been looking through similar threads, and it would seem people normally have a few dozen reallocated sectors. From what I understand I have ~40 million, unless I'm not reading it right (please see the screenshot below).

If that is the case, shouldn't the drive have failed catastrophically the smart test? I only see a caution, and the threshold seems still quite a ways off.

The system seems to be working fine so far, but I've only used it for a few hours (please see backstory at the bottom). I will of course continue monitoring to see if the reallocated sectors increase. But if it's truly reallocated 40mil already, how much more of an increase would be noteworthy 10 sectors? 100? 1000? 1mil?

Anyway, I would appreciate if someone clued me in on this reallocated sector count number, and why it is so large.

Backstory: The drive has been used for a year in a laptop. One day windows stopped booting. Turns out the boot sectors/partition table got corrupted and the system ntfs partition was showing as "raw". Drive has been completely wiped with "vivad" (akin to seatools), and bad sectors checked and remapped (132 sectors were remapped at the end of that operation according to vivad). Straight after that I've installed the windows os anew, all the drivers and various software (browsers, office, etc). Finally, I ran crystaldiskinfo - the screenshot above is what I saw.

Click on Fuction -> Advanced Features -> Raw Values -> set it to 10 DEC

But this is the full value

40,833,952

honestly I'm amazed at how that drive is still running! Yea don't use it. Get a new drive.

I did set it to decimal after I took the screenshot, and yeah, that is the raw number it's showing there.

I just don't understand if it's so big, how come both the smart stats don't indicate it being a big problem (just a caution) and the system itself seems to be performing just fine. I've run chkdsk /r after that, and everything's turning up ok. The count doesn't seem to be increasing.

Rest of the smart data (this time in dec).

Yea I'm not sure why it isn't more of a danger. I mean most drives crap out after 500 sectors! and here you are at 40 mill? Yea just dump the drive though.

The drive belongs to a friend, so I will definitely suggest to him to get rid of it, thank you.

It is an interesting case, though. Here is some more weird data.

HD Sentinel:

Two things stand out:
1. The reallocated sectors count raw value increased since yesterday by 65544.
2. HD Sentinel shows there are 5040 bad sectors. Both Sentinel and CrystalDiskInfo smart data show reallocated sectors count as 40965040. Can't be a coincidence, can it?

it could be. I've never seen crystal disk with a number that high. The highest I have ever seen it was with an old Seagate drive of mine. An 1.5TB drive. I was wondering why my PC was so slow, then i found crystal disk info and then found out i had 5000 reallocated sectors counts. Got that drive replaced 4 times! Each replacment lasted half as long as the last one. Make me feel like they just cleared the drive and sent the same one back to me. Ugh.

I am new at this and I am aware this is an old post but I am posting this for anyone who winds up with this problem for future reference.

Carey Holzman (youtube his crystaldisk segment) specifically states that Crystal Disk Info may have problems reading hard drives that are 1.5 Tb or larger and may erroneously report a "Caution" on these drives. The user has to use his best judgement on whether or not to trust the drive. It has been driving me nuts that many hard drives I own that are 2 tb that have been ok or with little use have been reporting cautions. For my part I just back them up and keep using them until the day they fail..

I only read that was an issue on the Samsung HDD's, which i have a few of their 2TB Spinpoints, and never had the issue. I have yet to have crystal disk info misread me info until this post here.
