Samsung ssd 840 series firmware update mac

Any idea how to get that running? I'm on Yosemite with all machines, so rEFInd doesn't seem to be so easy to and i'm not sure if it would be a good idea to use it to get something like freedos running or whatever that Samsung tools need to get running. S: I've got problems with the SSD getting slow and have serious problems with a freezing finder where i hope the firmware update and the performance restauration help to get it running again. Just to give you a reason why i want to update the firmware. Make sure you always fetch the latest Magician first, otherwise older versions claim the firmware is up to date, even if it is blatantly older than any other SSD in that machine!

As it turned out, I still needed to actually clone my boot partition, format to NTFS, reperform on Windows, then clone back - before I got back the drive's speed to as it was when new. Apple does not expose the necessary driver stack for such disk interaction.


It's the same thing stopping them from making Trim drivers or firmware upgrade utilities for OS X, and is why you have to use Boot CDs. Neither Samsung's 'bootable' image nor FreeDOS have the necessary EFI boot loader so it's either a lot of typing in Terminal [Google translated from French original] for the brave, or one of the following methods…. To use the bootable media, insert it and then restart the Mac while holding down the Option key. This displays the list of connected bootable volumes. From this point on, the Samsung Performance Restoration utility takes over and works pretty much as it says in the Installation Guide.

The tool first installs a firmware update on the drive itself.

Running the update

When the firmware update is done, the software goes through a two-step process which includes recalibrating all the data on the drive. This can take a while and it depends on how big your SSD is.

Do not interrupt the process. At this point you can just hold down the Power button on your Mac until it turns off, there appears to be no way to do a soft reboot from this point. If you want to eject the optical disc, hold down the mouse or trackpad button during restart and the Mac will pop out the disc before it even gets to the desktop.

Update: I cannot get my own machine, Mac Pro 3,1 [Early ] to work by any of the above methods. Next will be to just back it up, drop it in a PC, do it there. I don't think the necessary driver for the thunderbolt interface is included in the isolinux provided, at least i couldn't find any traces in the iso. Additionally Samsung advices to backup all your data on the SSD before updating the firmware or executing the performance restoration software.

Please first check Samsung Performance Restoration Manual before updating the firmware and particularly General Limitations: 4 13 If you have bootcamp installed, i would recommend running the Magician tool provided by Samsung there. Works like a charm and much more intuitive than working with the bootable usb drive or a bootable dvd method.

The Magician software also checks if you need to do any additional things other than updating the firmware, so it could save you a lot of time. I was done in 5 mins. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Any help? Tetsujin I also ran smartctl on the device. The firmware is out of date, and I've gotten a lot of CRC errors, yet the health self-assessment passes?

Yes, there is a newer firmware available, which might improve things a bit. If you really want to try to update it, you need a Windows Machine and the software from Samsung. But I wouldn't try a firmware update at this point, it could make things worse as well. The CRC errors I think I spotted a relevant error message: sda: unknown partition table.

It seems that there is no partition table on it, perhaps it was overwritten? Well, I don't have a Windows or Mac machine so the only option there would be to reverse-engineer the firmware, which would be highly difficult at my current skill level. I'll keep it in mind, though. I do travel with it on occasion. It's attached via SATA. I'll try re-seating it. Most of the PHYs are figured out mostly now. The sectors can be read out directly from flash now. So I decided to remount the SSD today. Sadly, the LCD screen seems to have become rather Then I slowly remembered that I had swapped the main kernel with the backup kernel to see if my problem was a kernel problem, but I also swapped the U-Boot image, which used the UUID to detect the boot device.

I had made a dumb. So I fixed that and I can get into my OS at boot again. I'm not sure what the root cause of my SSD problem is yet -- I had a kernel log but it accidentally got nuked in a fit of poor multitasking a few days ago. I'm going to disable irq-balance since that's the only thing I can think of that would cause this and see if the problem crops up again.

It is about times slower than a Novena, but for bigger amounts of data you want to use SATA anyway.
