SATA SSD Detection Error

krishnaraj_d · ‎01-13-2016

Hi,

I am using P2040 Processor with Linux-3.8.13-rt9 which comply with Serial ATA 2.6 specification. I was using SATA1 port of processor to plug in external 128GB SSD. Recently higher memory requirement came for 512 GB or above. When the 512 GB is plugged in the place of 128GB , it is not working. Errors where shown on the device boot up.

Both SSD are of same make, but 128GB supports SATA2 and 512GB supports SATA3. I guess SATA3 is backward compliant. I have checked the 512GB SSD in a Ubuntu14.0 PC and it is getting detected properly. From the error log, I could find that the device is getting is detected with its size. But due to some reason, Linux is not able to mount it. Whether the size(512GB) could be the reason? If there are any pointers someone could provide, it would be awesome.

The relevant booting messages are copied below.

Hello Yiping/Krishnaraj,

I have T1040 RDB. I am looking to use SSD on SATA 2.0 interface. Could you recommend some SSD (128GB/256GB) which is compatible with T1040. That will be very helpful.

Because I am looking to purchase SSD from market. If anyone already using working SSD. Please give me the details of the manufacturer.

Thanks in advance.

Reagards,

Hello Krishnaraj,

I think this problem is caused by P2040 SATA controller incompatible with your SATA 3.0 512M device. You need choose SATA device which is available to switch to SATA 2.0(3Gbps).

The following is P2040 SATA controller features.

• Designed to comply with Serial ATA 2.6 Specification

• Supports speeds: 1.5 Gbps (first-generation SATA), 3 Gbps (second-generation

SATA)

Have a great day,
Yiping

Hello Yiping,

Thank you for the reply.

I too doubted the SATA SSD. But I have two confusing points

a) On a Linux PC with 3Gbps interface, I didn't face any issue. SSD was getting loaded without any error. Also I read that SATA3.0 is backward compatible with SATA2.0. So that shall not be an issue.

b) I tried Loading an HDD 6Gbps in the same slot which worked without error.

Could you recommend some SSD (512GB/1TB) which is compatible with P2040. That will be very helpful.

Best Regards

Krishnaraj

Hello Krishnaraj,

Backward compatiblity means that SATA 3.0(6Gb/s) hosts and drives will operate when connecting a 3GB/s or 1.5G/s drives and hosts, by automatically dropping to the appropriate transfer rates.

So please confirm with the SDD producer whether their drives can be connected to all SATA 2.0 hosts(including P2040).

Have a great day,
Yiping

Hi Yiping,

I have checked with the manufacturer. They told that SSD can work with SATA2.0 hosts.

Then in order to confirm this, with the help of manufacturer I have downgraded the SSD firmware to force SATA2. Once the SSD is made SATA2, it worked with P2040 without any issues.

Have a nice day,

Krishnaraj
