Hello all,
Recently I acquired a couple of lightly used OEM Samsung SSDs from Lenovo Thinkpad laptops. I am using them in my desktop now.
I noticed the drives had very slow write speed (40-50% of the read speed) and after troubleshooting everything I could, I noticed that Lenovo had released a firmware update which enables TRIM. Thinking this may be the contributor to my slow write speeds, I downloaded and burned the bootable image for the update.
Upon booting from the disc, I get Nero Bootloader with a version number, and then simply:
Non-system disk or disk error
Replace and press any key to continue
I'm thinking that the update utility from Lenovo accesses something on a secondary partition that the drive is supposed to have, or something... I could be wrong. Anyway I burned the disc again (a whole 30 MB!) and did a Verify this time, and all the data was written correctly. This disc gave me the same error as above.
The drives are Samsung MMCRE28G8MXP-0VBL1 128 GB SSDs.
It may be worth mentioning that I have these two drives in a stripe in Windows. This was not done through the BIOS, so I figure it should not affect the update. If this is the case I have the data backed up, so I can easily dismantle the RAID if necessary.
Also worth noting is that I tried to use Samsung Magician to update the firmware, but it simply did not recognize the drives, probably because they're OEM. My BIOS is using AHCI mode for SATA as well.
Any and all help is greatly appreciated.
edit: Just for comparison's sake, here are benchmarks for the two Samsung OEM SSDs vs. my main Corsair SSD:
Samsung1: http://d.pr/i/FdwU
Samsung2: http://d.pr/i/ceqO
Corsair: http://d.pr/i/2i3Y
The bootable ISO for the update was acquired from here: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-69806
