I am building a new system using an Kingston 240GB SSD drive I pulled from my notebook (when I had to upgrade to a 500GB SSD drive). Centos install went fine and ran for a couple days then got errors on the console. Here is an example:

Eventually, I could not do anything on the system. Not even a 'reboot'. I had to do a cold power cycle to bring things back.

Is there anything to do about this or trash the drive and start anew?

Make sure the cables and power supply are ok. Try the drive in another machine
that has a different controller to see if there is an incompatibility between
the drive and the controller.

You could make a btrfs file system on the whole device: that should say that
a trim operation is performed for the whole device. Maybe that helps.

This is a Centos7-armv7hl install which is done by dd the provided image onto a drive, so really can't alter the provided file systems much other than to resize them. What I have is:

Model: ATA KINGSTON SV300S3 (scsi)
Disk /dev/sda: 240GB
Sector size (logical/physical): 512B/512B
Pa...

rtition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
1 1049kB 1075MB 1074MB primary ext3
2 1075MB 2149MB 1074MB primary linux-swap(v1)
3 2149MB 240GB 238GB primary ext4





If the errors persist, replace the drive. I´d use Intel SSDs because they
seam to have the least problems with broken firmwares. Do not use SSDs with
hardware RAID controllers unless the SSDs were designed for this application.
