Re: [CentOS] Errors on an SSD drive

is that because the drive is compressing the information?  is there a way to turn this off?  i hate mandatory compression as losing one bit in a compressed file tends to be a big deal compared to the same in an uncompressed file. -- Securely sent with Tutanota. Claim your encrypted mailbox

Re: [CentOS] Errors on an SSD drive

If it's a bad sector problem, you'd write to sector 17066160 and see if the drive complies or spits back a write error. It looks like a bad sector in that the same LBA is reported each time but I've only ever seen this with both a read error and a UNC error. So I'm not sure it's a bad sector.
