T420 CAN'T INSTALL SMART CARD FREE
Total free space is 125045357 sectors (59.6 GiB) Partitions will be aligned on 2048-sector boundaries So I set it up as a GPT drive and create a single partition:ĭisk /dev/sdb: 125045424 sectors, 59.6 GiBĭisk identifier (GUID): 525BD309-1EB5-4DEB-BD64-079173AEA9DFįirst usable sector is 34, last usable sector is 125045390 This requires working within a filesystem, but none exist yet on the drive.
Writing is about 55% faster, and the access time is 100x faster!įinally, using dd. Now for gnome-disks (in the gnome-disk-utility package):Īgain, reading is about 2.5x faster. The cached read for the SSD is pretty much the same, but the buffered read is 2.5x faster. Timing buffered disk reads: 778 MB in 3.01 seconds = 258.87 MB/sec Timing cached reads: 10012 MB in 2.00 seconds = 5009.12 MB/sec Timing buffered disk reads: 302 MB in 3.01 seconds = 100.23 MB/sec Timing cached reads: 10234 MB in 2.00 seconds = 5120.32 MB/sec Below, /dev/sda is the regular hard drive and /dev/sdb is the SSD. Now for some quick benchmarks, as suggested on the Arch wiki.

So I won't bother with trying to update the firmware. It looks like it already has the latest firmware, 07MH (as found on the Crucial website):Īug 07 20:46:36 amonkira kernel: ata3.00: ATA-9: M4-CT064M4SSD3, 07MH, max UDMA/100Īug 07 20:46:36 amonkira kernel: scsi 2:0:0:0: Direct-Access ATA M4-CT064M4SSD3 07MH PQ: 0 ANSI: 5 I booted it up, and saw that it was recognized:Īug 07 20:46:36 amonkira kernel: sd 2:0:0:0: 125045424 512-byte logical blocks: (64.0 GB/59.6 GiB)Īug 07 20:46:36 amonkira kernel: sd 2:0:0:0: Write Protect is offĪug 07 20:46:36 amonkira kernel: sd 2:0:0:0: Mode Sense: 00 3a 00 00Īug 07 20:46:36 amonkira kernel: sd 2:0:0:0: Write cache: enabled, read cache: enabled, doesn't support DPO or FUAĪug 07 20:46:36 amonkira kernel: sdb: unknown partition tableĪug 07 20:46:36 amonkira kernel: sd 2:0:0:0: Attached SCSI disk
T420 CAN'T INSTALL SMART CARD MANUAL
(Here's the Lenovo T420 Hardware Maintenance Manual for the official instructions.) I opened up a back cover, note it's even smaller than the RAM:Īnd here is the SSD installed (I moved the WWAN leads to the side): The Crucial m4 uses a Marvell controller without any compression. The Mushkin mSATA drives are highly rated, but they use SandForce controllers, so they're out. So it's better to have a "dumb" controller that doesn't try to compress my data. Since only encrypted data will be written to the SSD, compression will have no effect and will just slow things down. SandForce controllers play tricks with compression to get a higher write speed.
When it comes to hardware, the first priority is to not use an SSD with a SandForce controller.
However, I realize that government-grade resources may circumvent my encryption, or I could be phished, fall prey to malware, or otherwise compromised. If my laptop were ever lost or stolen, my mind would be at ease that its contents would not be recoverable to any casual (or even determined) third party. It's been harder to find much information on using multiple hard disks with LUKS and SSD encryption, so hopefully this post will help.Īlso, when it comes to security, I want enough security/encryption to be careful, but not paranoid or terribly inconvenient (yes, yes, I know security and convenience is a tradeoff). Keeping an eye to security, I want the speed of the SSD but still the security of my full-disk encryption setup, covered previously. I want a hybrid setup, where the SSD is used mainly for the operating system, and the other hard drive for large, less-frequently-access files (music, large datasets for my research, backups, etc). I am most interested in having faster disk access and possibly lower power consumption, if I can get my platter-based hard drive to spin down if I don't need it.
T420 CAN'T INSTALL SMART CARD DRIVER
Strange as i though when i installed the driver from Lenovo it would indeed get installed but it seems not.Īnyway.SSDs have many benefits over traditional hard drives. you may need to install the driver from the Lenovo website to get this)Īfter clicking ok or whatever was necessary I then went back and tested by opening the camera app on Win10 and finally it was working.
T420 CAN'T INSTALL SMART CARD SOFTWARE
I selected the option to Browse my computer for driver software and then went toĬ:\DRIVERS\WIN\CAMERA and selected the camera driver in there. I went to Device manager, found the camera, right clicked and selected properties, clicked on the driver tab and then went to Update Driver. Had installed Lenovo Settings, installed that Dependency package, had removed and added the camera back multiple times, removed all camera related software in add/remove and yet nothing.īut.
