Died two HDD Seagate 7200.11 DiamondMax 1TB and 500GB, the latter was bought three weeks ago.

Diagnosis - when booting BIOS lag 1-2 minutes, after which the disks are not detected. When the screws from the network, no lag.

What should I do?

1000GB: ST31000340AS
500GB: STM3500320AS

At standing system, a lot of data. Survived - had decided to marry off (do not screw it and three months), but here's how it happened. Next spent only three weeks.

You can ask if I have the screws, for example, brought them to our support team?
