Uncorrectable Error Count - Intel 520 SSD

Hi,

I was surprised to find out how big the raw value of Uncorrectable Error Count for my drive is: 220147178. The rest of the attributes in SMART seem to have normal values. I've checked the value both in Windows 7 64-bit using Intel SSD Toolbox (3.0.2) and GNU/Linux using smartmontools. I've also noticed it grows quite rapidly when using the ssd.

According to the documentation Intel 520 SSD Product Spec:

The raw value shows the count of errors that could not be recovered using Error Correction Code (ECC). Full Diagnostic Scan in Intel SSD Toolbox passes without errors. Furthermore in linux I have successfully copied many big files (checked their md5sums). The funny thing is that after running the Full Diagnostic Scan the raw value is smaller: 169588940 (overflow?). I also found some screenshots from anandtech's review of Intel 520 SSD and his Uncorrectable Error Count raw value was 0. Motherboard: Gigabyte P35-DS3L (yes, SATA2...) Any ideas what's going on?

Thanks in advance!
