Although this is a fun idea, it's just putting an SD card into a 3.5" floppy disk case and then wiring up the read/write head with contacts to make it appear like an insertion of a normal mass storage SD card. A more accurate title would be "putting an SD card in a floppy disk case"

Makes me ponder a 3.5" SD reader with a eject button though.

Or maybe a 3.5" SD card filled with SD technology ... I wonder how much storage that would be.

It bugs me that unmounting SD cards / USB drives and physically removing it are two seperate actions. To be fair, this was always a problem, also with old computers and OSes. There was no link between pressing eject and magical things happening in the machine to commit data. The data was simply a…

> the problem of people not being able to get their disks out of their machines if the OS for some reason refused to release it My first time on a Mac, about 1990, I felt pretty confident having plenty of early PC experience. A graphic designer I shared a house with had left me alone with (and permission to use) her Mac. I quickly discerned there was no software of interest actually installed, but found a floppy that…

My first interaction with a Mac (late '90s), I watched the Mac user:

* Drag the disc icon to the trash can to eject the disc.

* Pull the power cord since there were no other way they knew of to turn it off.

Mac's reputation as a usable computer was severely impacted, needless to say :).

They advertise their size. Back in the day, there were programs that let you reformat disks with tweaked parameters -- sectors per track, interleaving, etc -- so you could get a greater capacity. Windows 95 was shipped on a disk formatted for 1680k, for example [1]. Off the shelf disks were hit or miss as far as how big you could reformat them to, with some able to handle close to two megs, and others not able to han…

Exactly, it reminds me of the time when I formatted a HD 3.5" floppy to 2M with the aforementioned excellent 2M3.0 tool by Ciriaco García de Celis (Facultad de Ciencias de Valladolid: Grupo Universitario de Informatica). It provided 500 Kb of more available data beyond the 1.44M (more then fdformat). From a 2M dos bootdisk I launched a stripped version of win3.1, extracted the WIN3.UC2 archive to a ramdrive of 6M or…

It's slightly amusing to me that floppy disks were once called "HD", even though the abbreviation stood for high density rather than high definition.

If he could get the drive eject button to unmount the SD card, this would actually be more functional that current tech. It bugs me that unmounting SD cards / USB drives and physically removing it are two seperate actions. It's a regression in usability after floppies and CD-ROMs.

I really wish there had been a bigger push towards some kind of standardized packet writing for DVDRW (CDRW had this issue with a one use calibration track), so that they could behave more like floppies (drag and drop file transfers etc). The media itself is fully passive, while a SD card or thumbdrive have logic sitting between the USB interface and the raw flash. Thus optical media can be "rescued" by simply gettin…

Light reading about optical disc packet writing for anyone new the subject:

I would like to see the 3.5" floppy do a comeback, for instance as a 1TB+ flash drive. It is large enough that you can comfortably handle it physically and label it, maybe it could be a small throwback to the age of floppies and zip drives.

As cool as that'd be and my first thought as well. Then I realized the fat that most all laptops and tablets out there that Re too thin to ever handle something like that makes me think it's less likely to happen.

Good catch! I had completely forgotten about that one. For those completely oblivious to this: This was actually not about getting data written to disk, but to physically protect the drive from its own mechanical construction. The "park" command would cause the harddrive to move its magnetic read and write-heads away from the internal platters, so that when it was powered down and the disks stopped spinning, the plat…

I still type "sync;sync;sync" before I unmount something. (This used to be how you'd tell the tape-spooler to rewind..)

Reminds me: Sysinternals Sync on Windows.

Always, always sync -r after writing to a zip drive on Windows. Even minutes after you think it is finished writing, do not trust the OS to have finished flushing to disk.

I was struck by a talk by Kirk Knoernschild in 2013 where he pointed out that there is now a generation of users who don't know what a floppy disk is... Yet it is still the "save" icon in nearly every application.

Before those, you had double density "DD" disks -- and extended density "ED" disks after that. With the sleeve encased floppies you could even throw in single-sided and double-sided variants. Growing up, we had a lot of 1200KB 5-1/4 disks. IIRC, they were enough cheaper than 1440KB 3-1/2 disks for close to the same storage.

It is only required if you enabled write-caching for removable media. As far as I know this has never been enabled by default.

> It is only required if you enabled write-caching for removable media. No, it's always required, because applications may be writing to the drive.

I have never done it, and never had any problems. I always assumed it was a feature that only was needed for devices that had some sort of physical requirement for safe shutdown (spinning rust or the like).
