This is most likely a faulty 8 gig card.
If you search through the kernel logs, you will probably see error
messages mentioning "cannot read block X" etc.
I have even seen systems that are very unstable, no errors in the
logs, but replacing the SD card fixed the problem.

In general, when you see the errors you are seeing, it is likely to
have mounted the device read-only, which it why you cannot edit it.
SSD and flash disks etc. have a common failure mode, where they go
read-only when they fail.

8 gig card is cheap to replace. Try that.

Kind Regards
