Hi,

If it's just a FW problem, it's possible to repair, with special tools or special knowledge of the commands for it.
But those drives are very prone to head crash, and that could be also a problem on those.

How many of those to repair do you have?

[BlackST]

Yes I repair them, but I second dmarques about probability of media damage, especially if they were on 24x7 server use - if there is a media damage or head crash, the drive usually has a different behaviour and can be noticed, despite the 0MB capacity.

how i repair it?
what must i do?

[dmarques]

It's not as easy as that.
But if you do want to repair them by your own, you can start reading here: http://www.t10.org/
This will let you understand how SAS drives read and write and the necessary commands to do it.
After that, you start start your own tests.

Other option is to outsource or buy an expensive tool to do that.

ohh, is this not the same FW Bug of Barracuda 7200?

[dmarques]

It might have some issues similar, but anyway the way of fixing them is totally different.
