OT -Deleting and formatting a SD media card onwin8

bill-kranz wrote on 7/24/2015, 11:42 PM
I cannot see a right click menu pick for deleting a .MOV video file from a PNY 8 GB media card.
And when I try to format said card it says it is write protected which is untrue.

Have these cards changed to where you can only re-record over them?

Is this a bug in Windows 8?

I thought for sure I could both delete individual clips and format as needed
but maybe that was my Win XP days???

Thanks for any tips.

I presume you're an administrator.
When you click on the card can you see the files?

If you can't format, the card manufacturer may have a format tool that you can download.

I had a 16gb micro SD that I used to hack a nook to an android tablet and it re-partitioned the micro SD so windows could only see a 4gb partition. No matter what I did, Win 8.1 and the manufacturer's app could not re-partition or format the card back to the original 16gb.

Windows is limited to what it can recover from disks.

I ended up using a bootable cd of Puppy Linux and used linux partition manager to remove and repartition the micro SD back to normal.

You should always format media cards from the camera that's going to use them. Never format them from a PC. (i.e., just because you CAN format them on a PC doesn't mean you SHOULD) This is to ensure that your OS isn't doing something to the card that the camera will not like.

+1 x 110% jr.

after a miserable experience many years ago spent hopelessly trying to use a cf card that had been formatted on a pc and which refused to be reformatted in a camera (canon) i have never formatted a camera card (video or dslr) in anything but the camera it is used in. NOR have i reformatted any cards after an initial format. i simply use 'delete all' from the devices menu.

i haven't had a problem with any card (cf or sdhc) in the last 6 or so years.

I don't have much time to explain, but you even use a CanonSX50 formatted card in the CanonSX60. The SD Card needs to formatted in the SX60.

Do an online search for "external drive writeprotected in windows 8". Something something gets messed up and you need to manually unlock the drive. I've had it happen occasionally since XP.

After using ~7 versions of DOS and OS/2 I avoided the CMD window for years. Then, I discovered the DISKPART command and how powerful it is. These days that one command brings me great joy to work in a black and white screen again. 'cause I can get things done without saying "Mother, may I?" and doing the secret handshake.

I tried the DISKPART and it said "disk attributes cleared successfully" but I took it to another Win 7 PC and the files were still there.

So now I used the camera to format it.

Thanks for the tip I will investigate more and see where I may have went wrong.

To the other posters: Thanks for your thoughts also!! I was logged in as admin.

Take care,

Maybe your sd card device cannot format it because it is not fully compatible with your sd card. In this case, you can read files, but you cannot format your card. You cannot delete files too
Use another sd card reader to check !
Of course, if you used your device under windows 7, then problem comes from Win 8 !
