Wallet sync stuck log showing "sync from fork point failed err: disk I/O error"

[Odeezl]

Last week I had an issue that the OS SDD was too full due to the Chia database size so I needed to move the DB to another hard drive. I had some issues and ended up deleting the DB thinking I would just point the the other SSD my editing the config.yaml file.
Once I did that sync has started and I thought everything is good.
But when synced got to about 430,000, syncing stopped. Not sure what the issue is, I started the process again, deleted the DB and started a new sync, but exactly the same thing happened.
Checking the logs, I see the message "sync from fork point failed err: disk I/O error"

Anyone know what the issue is?
The SDD formatting maybe?

Would appreciate any help
