P72 will not read SDXC card

Problem:

Brand new P72 reads low density SD card eg 32MB OK.

P72 can't read 128GB microSDXC card in the same slot. (The microSDXC sits inside an SD adapter)

Same 128 GB microSDXC card in it's SD adapter tested on Lenovo W500 (10 years old) - reads OK.

128 GB MicroSDXC card inserted into a USB drive converter and put into a USB port of P72 - won't read.

P72 updated to latest auto updates including BIOS

P72 updated to latest WIN10

Device manager reports the latest driver for SD slot is already installed. (Driver appears to be a windows driver)

Doesn't appear to be a way to uninstall current driver and re-install it.

 

Any suggestions? Thank you.

Re: P72 will not read SDXC card

Hello,

 

If the card cannot be read inside the ThinkPad P72's card slot or via a USB reader, I would think it has been formatted using a file system that the ThinkPad P72 cannot recognize.  You could try copying any data off of it that you need on the ThinkPad W500, then inserting it into the ThinkPad P72, running Disk Management (filename: DISKMGMT.MSC) and partitioning and formatting it from there.

Re: P72 will not read SDXC card

Thanks, but this is a workaround. The reason I have a brand new P72 is that I have upgraded from a relatively slower W500. A 10 year old W500 is able to read a modern (Pentax 2018 JPEG format) disc while a 2019 P72 can not do the same is somewhat is alarming. I have no issues getting the data from the SD disc by other means, but I don't want a workaround each time I want to import pictures into my P72. My hope is that it is a driver issue that needs to be able to handle 128GB discs, both in the SD slot and apparently in the USB socket via an adapter. Also the hope is that it's a Win10 driver issue as I am a reluctant, dragged by my hair, screaming and forced W10 convert!

Re: P72 will not read SDXC card

A further test:

Format 32 MB SD card in Pentax camera and read on P72 - works fine. 

Format 128GB SDXC card in Pentax and read on P72 - does not read (but computer bleeps that it detected someting in the card slot)

Format 128GBSDXC card in Pentax and insert into USB converter - P72 does not read (but computer bleeps that it detected someting in the USB socket) 

 

So rather than being a format issue, it seems that the P72 has some issues addressing memory greater than / equal to 128GB? Since it can't do this in the SD card slot or the USB  slot. I don't have lower GB in hand to test the 'cut-off' memory it won't read.

Re: P72 will not read SDXC card

Dear Aryeh Goretsky,

 

So I tried the workaround you suggested to see if anything works:

Inserted the 128GB SDXC into P72 and found it on Disk Management in Win10: see below

Shows the SDXC card (Label k-70) as file system exFAT. Appears to read memory allocation correctly. 

When trying to view it (clicking on yellow icon folder) - no file manager menu appears.

Next attempt to format to NTFS. Gives error as shown: "the system cannot find the file specified."

BTW tried to do the same thing by inserting the SDXC into a USB converter stick: gives the same info and the same error.

A 32GB SD card from the same camera is formatted  FAT and P72 has no issue reading it. 

 

Is P72 able to decipher exFAT file systems? (Thinkpad W500 10 years old can) which have a higher memory size?

This seems to be the only difference, since the system can clearly count the 128MB memory but not decipher it?

Re: P72 will not read SDXC card

Hello,

 

Let's see if wiping the SDXC card in the ThinkPad P72 first will allow it to be formatted.  Here's how to do that, step-by-step:

 

1.  Run DiskPart (filename: DISKPART.EXE).  A DISKPART> prompt will appear in a CLI window.

2.  At the DISKPART> prompt, type LIST DISK and press Enter.  A list of disks with their associated numbers will be displayed.  In your Disk Management screen shot, the SDXC card shows up as Disk 2.

3.  At the DISKPART> prompt, type SEL DISK 2 and press Enter (or replace "2" with whatever number shows up from the LIST DISK command, above).

4.  At the DISKPART> prompt, type CLEAN and press Enter.  This will erase the beginning of the SDXC Card, making it appear as a blank disk (all files on it will be lost).

5.  At the DISKPART> prompt, type CREATE PARTITION PRIMARY and press Enter.  This will create a new primary partition entry on the now-otherwise-blank SDXC card.

6.  At the DISKPART> prompt, type SELECT PARTITION 1 and press Enter.  This will select the newly created partition on the SDXC card.

7.  At the DISKPART> prompt, type FORMAT FS=EXFAT QUICK and press Enter.  This will format the partition you created with the ExFAT file system.

8.  At the At the DISKPART> prompt, type ASSIGN LETTER=Z and press Enter (or replace "Z" with the drive letter you wish to assign to the newly-formatted partition.

 

At this point, you can exit DiskPart, open Windows Explorer and check to see if your newly-formatted SDXC card is now seen in Windows 10 (or whichever versions you are running on the P72 and the W500).

Re: P72 will not read SDXC card

Hi,

 

I greatly appreciate the continued help.

 

I tried the steps on P72 Win10 and got an error at [4] Clean (see .png file) as well as a screen error "Please insert a disc into SDXC(E).
This is despite having the SDXC card already inserted into the SD card reader.

I ran Diskpart on the W500 Win 7 and got the exact same error on the same SDXC card (Diskpart was a 2008 version)

 

Curiously when I take some test pics on the Pentax, insert the card into either the P72 or W500 and run up to error at [4] Clean,
the SD card appears to lose the test pics and can no longer be read on the camera. So I have to reformat the SD card on the camera.
So something begins to happen at [4] Clean, may be it strips the header info off the SD card.

 

The Pentax formatted SDXC card appears to be exFAT according to disk management, so the P72 does "see" it or it's header info but not
read beyond that.


There are no menu options on the Pentax for any other formats.

 

The SDXC card is fully functional, the little switch on the edge of the card is set to 'unlock'.
It's contents can be read on the W500 Win7 by a SD to USB port converter or it's SD card slot, neither is true for the P72.

 

Thanks

Re: P72 will not read SDXC card

Hello,

 

This is certainly weird.   I am going to do some additional research on this.  In the meantime, there is one more thing I would like you to try, either on the W500, the P72, or both.  The Secure Digital Card Trade Association offers a format tool for download on their website at https://www.sdcard.org/downloads/formatter_4/.  Would you mind giving that a try and seeing if it works?

 

Regards,

Re: P72 will not read SDXC card

Hi,

 

It works! Thank you very much.

 

As you suggested I had to use the W500 to let the formatter see the SDXC card in the first place. I used quick format. Once I did that it could now be inserted into the P72 and it registered in E drive. Then inserted into the Pentax, take test pics and re-insert into P72 where it now reads the pics just fine.

 

So as you suspected it was the formatting and the Pentax clearly formats or puts something in the header that only it and the old W500 can see. Now I just have to keep it formatted off the sdcard.org program. I will write to Pentax and link your solution to them, I can't be the only one on the planet with a Pentax and P72.

 

Best regards

Re: P72 will not read SDXC card

Hello,

 

These types of issues can be kind of hard to troubleshoot, because your dealing with different generations of memory card controllers with difference device drivers running under different operating systems, which may have different versions of their file system drivers.  Glad you were able to solve it.
