Do not format the card Try only to write a new partition table. Otherwise your data will be lost for sure.

The same place that you got PhotoRec you can get test disc which will help you rebuild your partition table. Also has means to back up the disk. test disk is also in the repos.

Yes, use testdisk then. It will recover deleted partitions even after a new formatting. It is quite an amazing tool.

I wonder how that could work ... Formatting (at low level or "raw") the data area with some random bits will generally destroy the original content. But sure, it depends on the file systems and software. I will have a look into the source sometimes

But that is not what formatting usually does. It usually just only wipes the file system information.

Then you'll probably wonder why formatting is so fast, too Did you ever install Windows XP with real format on a big drive?

Well,

so far the Card is persistent in not accepting formating, partioning, changing cylinders/heads/sectors...
Regardless what tool I use, either the tool doesnot work (cfdisk refuses) or the card doesnot store new info on geometry etc...
Testdisk would run for hours without finding partion info or files to recover...

So its probably like Gapan said - if gone bad then no chance!

Why should I? I have my loved VirtualBox
To be honest, never installed Windoze "natively" since years. I see no need to do that nowadays.

Next time, buy a not so cheap but better card. What have you written? - You will buy again.
It is a real pity with those cards (and adapters for them).

Well,

its not a problem of the adapter its just the card.

I think as all SD-Cards will have problems with mechanical or electrostatic impact, there will be not much diference between the labels.
I have two other no-name SD-Cards working well...but it might be better not to look for the cheapest ones.
The adapter I would buy again, same!

Try to use testdisk or photorec on the file you backuped your SD card instead of the sd card directly.
