Review snippets: I ordered 4 of these and one had a tick and wouldn't detect in Disk Management. Sent it back and received this one... It's been in a JBOD for about 2 months, working fine. Only had 3200 hrs on it / Been using the drive for about a month, and no issues. Came securely packed and even included the adapter to disable PWDIS. Working as advertised and saved more than $100.
