Comment 52 for bug 1269777

Hi,

[Crucial M500 - a hope? - NO]
-------------------------------------------

after returning the Samsung and found this thread in the lenovo forum:

http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W510-SSD-My-Story/m-p/1402387

my hope was the Crucial M500 should be compatible to the W510:

Unfortunately, I encounterd the very same problems like with the other SSD's.
The ata port hard resets and the SSD goes into read-only state after a certain amount of time.

More or less stable I could get things running with turning PCIe powermanagement off in the BIOS an using libata.force=noncq as kernel boot parameters. Nevertheless the system freezes from time to time.

I will open a new bug report for this drive as soon as the

[Contacting Lenovo support]
-------------------------------------------

The lenovo support stated, that only very special SSDs from Intel with a capacity of 160GB are compatible with this device.
So no help from lenovo.

[FURTHER TESTING]
-----------------------------

Since the fact, that an older drive, the Samsung 830 is running fine in a laptop (Lenovo X201, i7) with the same laptop, I tested all drives (Samsung 840 EVO, PRO and the Crucial M500 480) in the X201. Same problem there. So it IS DEFINITELY an incompatibility with the drive and the machine / chipset / kernel.

Within the next weeks, I will try an older Crucial M4 256GB in the W510.
This is an older drive model like the Samsung 830 and probably will work.

[OPINION]
---------------

Comming across certain threads, this problem is very common an occurs here and there with certain chipsets.
I don't think it is a problem of the linux kernel, but probably could be fixed?

I will post my results about the Crucial M4 and the problems with the Crucial M500 and link here.
