programming for 30 years in most languages, and operating systems. 20+ years in UNIX, extensive experience in ATA/SATA, SCSI, SAS, FC, RAID, embedded, USB, multi-platform, pass-through SCSI, and most RAID controller APIs. Expert in metadata reconstruction of RAID; storage-related security/hacking/cracking;
You can hire me for $100-$250/hr depending on what you need. RAID data recovery will cost you more. If you are a worthwhile charity and are in a bind, I've been known to help for free. If the issue is appropriate for EE, then keep it on EE. If it is sensitive nature and/or the type of thing that needs hands-on, or is outside the scope of EE, then that is the time to take it offline.
