Lexar 64GB Jumpdrive Fingerprint F35 USB 3.0 Flash Drive for Storage Expansion and Backup, Up to 250MB/s Read, Black/Silver (LJDF35-64GBNL)

I had the idea years ago being tired of entering long passwords.It would be perfect if we can define several protected drives.The CD-drive(that contains the app to configure fingerprints), public and private space are all considered as different drives, not partitions.The speed is quite good, even though we don't buy this drive to get the most performant drive.I'd like to have more information on the technical encryption, is it software or hardware like OPAL compliant.Linux: It doesn't work very well on linux/Ubuntu 18.04. Once the drive is inserted, something keeps reading the drive (blinking led) and detect the new drive, it never settles down.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~fdisk -l after minutes~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Disk /dev/sdb: 9.8 GiB, 10522656768 bytes, 20552064 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisklabel type: dosDisk identifier: 0x77d82c38Device Boot Start End Sectors Size Id Type/dev/sdb1 56 20552063 20552008 9.8G 7 HPFS/NTFS/exFATDisk /dev/sdc: 47.9 GiB, 51418824704 bytes, 100427392 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisklabel type: dosDisk identifier: 0x77d82c34Device Boot Start End Sectors Size Id Type/dev/sdc1 56 100427391 100427336 47.9G 7 HPFS/NTFS/exFAT~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~dmesg~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[ 497.168816] usb 2-2: new SuperSpeed USB device number 7 using xhci_hcd[ 497.189561] usb 2-2: New USB device found, idVendor=21c4, idProduct=20bd[ 497.189563] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3[ 497.189565] usb 2-2: Product: Lexar F35[ 497.189567] usb 2-2: Manufacturer: Lexar[ 497.189568] usb 2-2: SerialNumber: 0101000000026428[ 497.190251] usb-storage 2-2:1.0: USB Mass Storage device detected[ 497.190369] scsi host1: usb-storage 2-2:1.0[ 498.210414] scsi 1:0:0:0: Direct-Access Lexar Lexar F35 1.00 PQ: 0 ANSI: 2[ 498.210892] scsi 1:0:0:1: Direct-Access Lexar Lexar F35 1.00 PQ: 0 ANSI: 2[ 498.211300] scsi 1:0:0:2: CD-ROM Lexar Lexar F35 1.00 PQ: 0 ANSI: 2[ 498.211910] sd 1:0:0:0: Attached scsi generic sg1 type 0[ 498.212199] sd 1:0:0:0: [sdb] 20552064 512-byte logical blocks: (10.5 GB/9.80 GiB)[ 498.212365] sd 1:0:0:0: [sdb] Write Protect is off[ 498.212371] sd 1:0:0:0: [sdb] Mode Sense: 03 00 00 00[ 498.212508] sd 1:0:0:1: Attached scsi generic sg2 type 0[ 498.212815] sd 1:0:0:0: [sdb] No Caching mode page found[ 498.212827] sd 1:0:0:0: [sdb] Assuming drive cache: write through[ 498.213098] sr 1:0:0:2: [sr0] scsi3-mmc drive: 0x/0x caddy[ 498.213430] sr 1:0:0:2: Attached scsi CD-ROM sr0[ 498.213686] sr 1:0:0:2: Attached scsi generic sg3 type 5[ 498.213950] sd 1:0:0:1: [sdc] Attached SCSI removable disk[ 498.216017] sdb: sdb1[ 498.217232] sd 1:0:0:0: [sdb] Attached SCSI removable disk~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Finger print to discover the private drive~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[ 531.951740] sd 1:0:0:1: [sdc] 100427392 512-byte logical blocks: (51.4 GB/47.9 GiB)[ 533.790859] sdc: sdc1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Eject the drive because it is being written continuously~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[ 556.873287] xhci_hcd 0000:00:14.0: Cannot set link state.[ 556.873302] usb usb2-port2: cannot disable (err = -32)[ 556.873316] usb 2-2: USB disconnect, device number 7[ 556.873692] sd 1:0:0:1: [sdc] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK[ 556.873702] sd 1:0:0:1: [sdc] tag#0 CDB: Read(10) 28 00 05 fc 62 f0 00 00 08 00[ 556.873707] print_req_error: I/O error, dev sdc, sector 100426480[ 556.873888] sd 1:0:0:1: [sdc] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK[ 556.873900] sd 1:0:0:1: [sdc] tag#0 CDB: Read(10) 28 00 05 fc 62 f0 00 00 08 00[ 556.873906] print_req_error: I/O error, dev sdc, sector 100426480[ 556.873920] Buffer I/O error on dev sdc, logical block 12553310, async page read~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-----------------------------------------------------------------------CrystalDiskMark 6.0.2 x64 (C) 2007-2018 hiyohiyoCrystal Dew World : https://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]* KB = 1000 bytes, KiB = 1024 bytesSequential Read (Q= 32,T= 1) : 171.994 MB/sSequential Write (Q= 32,T= 1) : 85.724 MB/sRandom Read 4KiB (Q= 8,T= 8) : 6.218 MB/s [ 1518.1 IOPS]Random Write 4KiB (Q= 8,T= 8) : 3.045 MB/s [ 743.4 IOPS]Random Read 4KiB (Q= 32,T= 1) : 4.856 MB/s [ 1185.5 IOPS]Random Write 4KiB (Q= 32,T= 1) : 3.024 MB/s [ 738.3 IOPS]Random Read 4KiB (Q= 1,T= 1) : 4.394 MB/s [ 1072.8 IOPS]Random Write 4KiB (Q= 1,T= 1) : 2.871 MB/s [ 700.9 IOPS]Test : 1024 MiB [G: 0.1% (0.0/47.9 GiB)] (x3) [Interval=5 sec]Date : 2019/04/29 8:21:07OS : Windows 10 [10.0 Build 17763] (x64)

MAC USERS may find the install process a little annoying, especially since there is no specific instruction. I had to call Lexar to get an answer.The short version is that, while this product is fully compatible with MAC OS, it has to be installed and set up on a PC. Then it will cross over just fine. That isn't explained anywhere, so I found myself more than a little annoyed that I had to do the leg work on my own when it says it's compatible.So, I only nicked stars for "Ease of Use" -- Overall this is definitely a 5-Star Product. I love the added security of the fingerprint lock. It has a little clip hole for adding to your keys (which is something I wouldn't do on an unencrypted drive). And it has a little bit of weight to it, which I actually like. At USB 3.0, transfer speeds aren't fully up to modern snuff, but you're getting an excepted drive for under 50$. Still the best bang for your dollar as of date of review.

No problems with the stick itself. I suggest you program more than one finger to gain access. At first I only used one and quickly realized that two or more was more convenient for me.

I've always worried that if someone steals my laptop they will have my entire life info, as I scan everything, both business and personal docs. I finally got off my rear and did something about it; what a relief. I suppose a bad guy could borrow my finger to see my gas bill from 10 years ago,...I suppose.The fingerprint reader is super quick. The only con: I'm afraid that flexing the female port on my laptop by swiping the fingerprint reader sticking out the side will eventually damage said port. I think I'll get a cheap USB hub and see if that works.Anyway, I like it so much I just ordered a 2nd one: one for home, one for work.EDIT: just got the 2nd one, no box, no instructions, just in an orange bag that says "USED-LIKE NEW"!!! See pic. It's probably got some malware on it and will hack my PC; it's called a "USB drop attack." I ain't using it. Unless you want all your private info stolen: Don't ever plug in a strange USB stick you just "happened" to find.

Below find my last review. I'll be brief but wanted to follow up on my 3rd purchase. Died completely after 2 months. It overheated some every time I used it, but not bad. Then it just stopped working. Blew it out with air, hoping lint or dust was a problem, tried it on 3 different machines. Didn't last as long as the previous one, and even though it is a nice drive, it isn't working with the computer very well. Maybe a blocker for the constant barrage of apps wanting to snoop. Either way, not buying any more of them.I am a writer, and work on my stories between two different laptops, one at home and one at work. I like that the secure drive is not visible until you open it with your fingerprint. Most people would never know it's there. Most don't know trying to open a flash drive with a larger drive than their pc or laptop will be a problem either. :)The first one was a 64g, second one is 128g. I don't exactly know what went wrong with the first one, but I "suspect" my virus software kept trying to scan files even though it was not given permission, and the light flashed that it was working non-stop and it became very hot, and eventually it finally stopped working. The 128 one works good, but seems slower, and I am now purchasing a 64g again rather than a 32g mostly because I save media files with my documents also.I have to say I dislike the feature where it shuts off while I'm in the middle of a story (novel writing) and it's tricky getting it saved. If there is such activity on a protected file, it should stay active as long as the file is, or if nothing else it should save the file when it times out.
