There seems to be two separate issues with it vanishing from the BIOS:
The first is 'deep sleep' related, where the drive just won't wake up. The steps you've done above though should have sorted this.
The second is just near instant death. Gone. No BIOS recognition for you. A lot of people seem to think this is controller related and not firmware, but Sandforce have always been very quiet and never confirmed anything.
You need to keep in mind that not even Intel, with their extensive validation program on Cherryville could produce a drive that wasn't subject to BSOD and BIOS vanishing (although not as bad as others) issues on some systems.
