Hi Everybody, new in the forum and not a native speaker of English, but lets try.
Last weekend I was trying to repair a old Ocz revodrive 3 x2 240GB Pcie.
This card is composed of a marvell 88se9485 sas conrtoller connected to 4 sandforce controllers, each sandforce controller is connected to a bank of flash memories.
At the bios and at Windows the card shows itself like a scsi controller connected to a 240GB disk and at linux shows itself as 4 disks of 60GB.
At the beginning the SSD was correctly detected by windows, but one of the four sandforce controllers, connected to the marvell 88se9485, was not showing up.
Without ideas, I downloaded the ocz tools (now toshiba) and upgraded the firmware of the marvell and the of the sandforce controllers.
At the end I have discovered that the problem was only a tiny little coil that was broken, after the replacement of the coil, all 4 sandforce controllers are getting detected correctly.
But looks like the firmware upgrade of the marvell 88se9485 without one of the sandforce controller have screwed up the card config, now the card is not getting detected by windows.
Well, I m looking for a full dump of the firmware of the marvell 88se9485. It is a 25p40vp SPI flash marked as U1 on the board to try resurrect this board.
Thanks in advance
