Hier kann mal wieder ein Paradebeispiel für einen extrem miesen Support erleben.
Mittlerweile gibt es etliche Threads und Blogartikel dazu. Auch ich bin Opfer dieses Bugs geworden: totaler Datenverlust (Backup vorhanden).

Meine Supportanfrage bei Intel mit allen Details und der expliziten Angabe, dass ich Mac OS X benutze ergab folgende Standard-Antwort:

Thank you for contacting Intel® Customer Support.

For initial support, Intel recommends that you contact your point of purchase, who is in the best position to carry out troubleshooting and honor the warranty.

Should your reseller be unable to provide support, we need some system information and description of the problem to identify the root cause and to provide an adequate solution.

In order to assist you with your enquiry, we would like to suggest some troubleshooting steps which could solve the issue. Please reply to this email answering the questions below and we will forward your enquiry to our technical team if further support required:

SA and Serial number (iSN) of SSD (where can I find these numbers) and picture of the SSD label.
How old is the system?

To which motherboard or laptop is the SSD connected?
Is the SSD being used as a raid member or in AHCI configuration?
