Can anyone recommend a SD Card reader.
I have many from a mini USB with sockets for Micro SD / SD they often don’t work.
I purchased one of these

and it rarely works. It might work tomorrow but I need it today for a 64GB SD Card.
Maybe it’s the size (64GB) but then often my 8 to 16GB Micro SD cards don’t work.
The Hub reader (above picture) I purchased but they sent another. It was from Amazon, but it no longer exsists?
Do you know of a reader that works all the time, every time especially today (when I need one).
Edit: The above reader places a drive letter in Computer, when I insert a card I get a message

Cheers

October 30, 2017 at 12:37 am #13139@wasbit are you sure they was bought out, or was it thier way to hike the prices?
Yes, for a card reader, the pound shop will do. It won’t be the quickest, but hey, it’s a quid reader.
October 30, 2017 at 7:14 am #13141Never had one that didn’t work. Mostly I use the cheap plastic ones (sounds like Wasbits) usually with another converter inside it to deal with micro SD cards.
That message is usually caused by the card rather than the reader. Try using Disk Manager when the card is in to see if it’s there but corrupted.
October 30, 2017 at 7:52 am #13142I bought a cheap Transcend reader as I keep losing the little ones. The Transcend is usb3 and I have found it very reliable.and covers all the bases including cf cards.
October 30, 2017 at 9:30 am #13145Cheers for the suggestions, I will look in the £ shop
After looking in manager, failing that maybe the trancend I have one like it (popamazing)
Nine one

JohnOctober 30, 2017 at 10:05 am #13146Just to add to Dave’s comment, Win10 is incredibly picky about sticks and cards and will often grot-out if it cannot read a card properly. This is especially the case when moving files from ‘alien’ i.e. Linux/Android PCs/Phones. It gets very confused with alien file ownerships. I normally ignore all Win10 warnings and just open the card – nine times out of ten it will read the card ok. (especially bad when backing up pi files!)
October 30, 2017 at 6:27 pm #13156I have found in the past that its usualy best to format cards in the card reader rather than the device assuming that your device will then recognise the card !
I have also had trouble with ExFat formated cards. Seems it may not be as universal as it should be.
October 30, 2017 at 10:12 pm #13163Thanks Ed & Wheels
I looked in Disk Management (when the above is plugged in it gives it Drive I)
in disk man it shows as I empty. Today which is tomorrow (yesterday) it’s working fine?
It seems (as you say Ed) Win 10 is picky. In saying that the other rig is win7 not used the reader much but never noticed it being picky?
It seems I need to always use it tomorrow.
I will still try £ shop etc for another that might work today, as I can’t always wait till tomorrow???
Cheers
JohnOctober 31, 2017 at 9:09 am #13165John, I’ve been awake about 90mims, and now I have no idea what day it is.
Though it’s always today, and never tomorrow. But is it yesterday again?
Last nights star trek hasn’t helped either.
October 31, 2017 at 2:46 pm #13175From my experience Win7 SD file ownership is treated by Win10 as being almost as alien as a Linux fat32 SD. I suspect you do not have to buy a new card reader, just be patient with Windows 10 and let it do its unnecessary ‘repair’ of the SD card. If this irritates you then you could try disabling this repair loop. link
October 31, 2017 at 8:10 pm #13181Just a thought. I have two front USB ports, and both work, except with SD card readers. Then, only one is reliable with the other being hit and miss. May be worth just trying a different port.
Arch Linux, on a Ryzen 7 1800X, 32 GB, 5 (yes -5) HDs inc 5 SSDs, 4 RPi 3Bs + 1 RPi 4B - one as an NFS server with two more drives, PiHole (shut yours), Plex server, cloud server, and other random Pi stuff. Nice CoolerMaster case, 2 x NV GTX 1070 8GB, and a whopping 32" AOC 1440P monitor.
October 31, 2017 at 8:22 pm #13182Duke it is a tricky one, especially as Tomorrow never comes.
It is still working fine today, which is yesterday’s tomorrow.
Thanks for the link Ed I will try it once I have finished
using it today before tomorrow (hopefully)Thanks Dan, I will have to try it.
However as it’s connected to my PC it must have read this thread and is being good for now? When you talk about something it often does the opposite to make me out a fibber.
Cheers
JohnNovember 1, 2017 at 7:34 am #13184John, if the fix gives more problems than it solves then re-enable the service.
i.e.
2. Here locate Shell Hardware Detection service and double click on it.
3. In General tab, under Startup type set it to
Enabled and start the service or reboot.Obviously to change a Service you need to be an Administrator or ‘run as’ as an Administrator

I will have a go.
Cheers
