It seems this problem only affects the newer versions of the DTLA, the first models (of which type most of mine are) doesn't seem to suffer from this problem. The first models looks like the older DPTA drives, whereas the newer ones has at least a different top cover. Anyhow, the problem seem to be an electronics malfunction (IBM doesn't tell exactly) and it is triggered by the drive being very sensitive to the power supply being top quality. At any rate I think the hysteria about these drives is somewhat overrated, but thats only my oppinion... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
