SSD bad block -question.

[bledd]

Normally I'd just chuck a drive if it has issues, but this SSD isn't used for data that I care about.

First noticed issues when I couldn't take Macrium images any more on my HTPC, so this drive got swapped out to be my new external SSD for drivers etc.

Having run a surface test, it showed one bad block.


I've just done a 'fill drive with ones' in MiniTool Partition Wizard. Now upon scanning, I don't have the bad block showing.

Does this mean filling with ones has fixed it? Or has the SSD just marked it as a dud sector and allocated it a spare?

I'd bet that the drive has marked the sector as bad and a reallocated sector is now in use.

Which drive is it? I'm curious to see if SSDs act the same way as harddrive - when one bad sector appears, usually more and more appear until the drive is unusable.

A cheap old OCZ Agility 2 I believe.. 30GB
