bump??? no one have answer?
how to scan for death cells?
Its highly depend of architecture of SSD. Some SSD`s have spare cells area, so for some time they could compensate cell disposal (no capacity loss), some SSD`s use special algorithms for writing data into cells, using error correction codes (no data loss), some have both kind losses simultaneously. And Intel use SSD controllers from many vendors. If I remember correctly, in 510 Marvell controller used, so it have some error correction, but no spare zone.
As far as I know, damaged cells in SSD drives usually cause no data loss - they can be read, but cannot be rewritten and can be replaced by SSD controller using cells from spare area, which is completely invisible from the end user point of view. Only when spare area is used up, you will notice decrease of available disk space.
Just like with traditional HDDs, you can use SMART for monitoring drive health. ID 05 Reallocated Sector Count in RAW view will show how many cells of your SSD retired.
