| 1403411 | 2015-06-22 09:37:00 | I have windows 7 ultimate. on sata 1 controller, i have the 500gb boot drive, split into 2 partitions, boot and data. on sata 2 i have another data drive 1tb in size. on sata 3 i have a new 1tb drive unused. Now i cant get both of the drives on sata 2 and 3 to show at the same time in Windows. When sata 2 is disconnected, sata 3 shows. When sata 3 is disconnected , sata 2 shows. When both sata 2 and sata 3 are connected, only sata 2 shows. Sata 3 doesn't show in windows disk management, or in the bios. Got me puzzled. Sata 3 shows as not enabled in bios, so looks like both drives cant work at the same time, either one or the other but when both connected only whats physically connected to sata 2 shows. BIOS options all seem okay and set to default. Any ideas?? I have a 500w power supply and an ati radeon 2900 pro video card. Is it the power supply? Thanks in advance for your help. Cheers |

| 1403413 | 2015-06-22 10:42:00 | Had something similar changed the external drive letters to something that was not commonly used by other drives, i.e, I and F. | Whenu (9358) | ||
| 1403414 | 2015-06-22 10:49:00 | Had a similar problem on a customers PC about three months ago --- From memory (so it may be 100%) Main Drive was a SSD on a SATA3 controller, the others Standard drives, it was something to do with the SATA controllers on the motherboard. ( board had SATA2 & SATA3 Ports) If a certain drive was using SATA3 it over rode the other and somehow removed the drive letter completely ,placing both secondary drives on SATA2 controllers instead they all showed. ( something along those lines) |

| 1403415 | 2015-06-22 11:09:00 | Another thing you can try -- if you have another spare SATA drive remove either of the two drives and plug in the spare drive see if those two show at the same time. Last week had a really weird problem, the persons W7 laptop drive would work OK on their Laptop, but attach it and a new drive to a workshop PC to clone to a larger drive and it wouldn't show - The problem was with the drives data, partitions, once the data was copied off on the laptop to an external drive, I wiped the drive, repartitioned/Formatted, and it then displayed --- Weird. |

| 1403416 | 2015-06-22 21:47:00 | You say the drive isnt showing in the bios.....so it can only really be a motherboard issue. Nothing to do with Win or software. Try a bios update. Try other sata connectors on the bios |

| 1403418 | 2015-06-23 10:16:00 | Not one of those stupid boards where 1 port is shared with 2 connectors is it? (usually done with an internal and an eSata port, but designers sometimes do all sorts of weird things...) Sounds like a BIOS bug to me, though. |
