What did you do? Can you outline the steps? Any error messages you got?

I assume you plug the card into a reader on your computer? There's 3 sorts of card and 3 sorts of reader, nine ways you can connect physically, but 3 of those 9 don't work.
An XC card won't work in a HC slot.
An XC card won't work in a SD slot.
An HC card won't work in a SD slot.
It doesn't help the unsuspecting novice that all three are physically compatible. The type of card will be marked on it. The type of slot might be marked, or you might have to look it up in the machine's manual, or get an external slot that definitely is compatible with your card.

There's a similar situation with CD, DVD and BR disks...
A BR disk won't work in a DVD drive.
A BR disk won't work in a CD drive.
A DVD disk won't work in a CD drive.

i don't have any error messages. it just doesn't show up on the desk top or in the file manager, its an internal reader, i read somewhere that older computers need the card installed before it will load it. so i rebooted the computer and it still does not show up on the file manager or on the desktop.

What size card? Small to medium cards are formatted to FAT. Larger cards are formatted to junkFAT. Sorry, the correct name is exFAT. :-)
exFAT is proprietary to stop non Windows computers using it. Microsoft hope this will make Microsoft as obscenely profitable as Apple.

In most cases, you can format the card as FAT. Bill Gates will have to be satisfied with being only the second richest person on the planet.

Can you try any other distro from a live cd and check if the problem exists also on those?

Resorting to the command line is a pain. I inserted a USB disk then unmounted it.

Code: Select all

lsblk -a
returned the following line for the unmounted disk. You can also use

Code: Select all

lshw
. See if lshw or lsblk -a shows the device for you.
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb 8:16 1 0 disk

Code: Select all

sudo hdparm -I /dev/sdb
returned the following data.

/dev/sdb:
SG_IO: bad/missing sense data, sb[]: f0 00 05 00 00 00 00 14 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

"32GB slipped into a larger housing" So it can't be a microSD card, they only go up to 4GB.

I believe that micro sd cards over 2gb are considered to be sdhc. My laptops, 5 thinkpads and 2 hp's, all read my 16, 32 & 64gb micro sd(hc) cards in the full size sd adapter. I would expect the OP's card is either exfat or has a problem. I've run into a few cards that were formatted exfat as purchased. One can easily install exfat-fuse from the repository, or use gparted to blow away the exfat partition and re-format fat 32.

Regards
Bob

One of my 32 GB microSD cards in an adaptor as shown in

Code: Select all

lsblk -a
when mounted:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 29.1G 0 disk
└─mmcblk0p1 179:1 0 29.1G 0 part /media/peter/TOSHIBA32GB

The same 32 GB microSD card in an adaptor as shown in

Code: Select all

lsblk -a
when unmounted:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 29.1G 0 disk
└─mmcblk0p1 179:1 0 29.1G 0 part

When the microSD card is not mounted, the Disks application shows SD Card Reader /dev/mmcblk0 with partition W95 FAT32.

The following discussion covers installing exFAT code then using Gparted and Disks.

SO i was thinking maybe it was a hardware driver issue, so i thought why don't i just install recent distro updates. I have them shut off. I had some issues awhile back with auto updates of previous distros so now i manually update. Anyway after this recent update, and a shutdown and fresh boot up, the card came up. I can even mount it without a restart. Sorry to waste all yalls time, i don't know why i didn't think of this before.

I'm glad I don't have your problem...I added a 32GB Sandisk microSDHC card to my phone...when I connected the phone to the computer I got..."cannot mount" so I clicked ok and about 6 seconds later the phone's HD opened double clicked the new microSDHC card which opened and I put my Music in...you can be lucky sometimes. :D

Be careful with microSD to SD adapters, they fail sometimes. Please try:

- lsblk, then insert SD card, lsblk again and see if a new volume appears
- If a new volume appears, you can test it with e2fsck -v /dev/sdb1 (sdb1 or the new volume name that appears in your computer)
- Test the microSD card with another microSD to SD adapter in your computer
- Try to read the SD in another computer

After that we can see if the failure is in the adapter, in the card, in the computer or in the file system...

Indeed. I have trouble with one of mine, sometimes have to re-insert the card a couple of times before it works reliably.
