Does the drive leave you disappointed in its performance? Are you constantly trying to hide your drive from your friends because you are embarrassed to be seen with it? Do you go to sleep every night crying because of the empty feeling your drive leaves you inside? If so then yes, your drive has failed you.

Also, according to the errors that drive really is failing so go replace it. We'll all feel better.

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags

```text
 and 
```

by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

hi,
i dont think its good to make quick conclusion.
of course its terrible that you have hard errors, but anyway try first
repair deice in SVM, i mean force it for resync to the same device.
metareplace -e dx cxtxdxsx .. see man metareplace.
if it doesnt help try to repair, analyze at least in #format tool of solaris.

Good luck.
