I was using my 32gb microSD in my LG optimus Net, and my battery died, and after charging, my phone got stuck in a boot loop. so I removed the SD card, and restored to factory defaults,

I inserted my SD card, and the phone said it was blank, I tried it with my PC, and my PC said it was only 30MB

It was dual partitioned (for link2SD)

fdisk -l:

Disk /dev/sdb: 32 MB, 32096256 bytes 1 heads, 62 sectors/track, 1011 cylinders, total 62688 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000

Disk /dev/sdb doesn't contain a valid partition table


I tried formatting with windows/the phone/fdisk/fdisk in sectors mode/gparted. and none worked.

I tried using photorec, and photorec said it's too small.

I've tried 3 micro sd reader.

I have a bunch of important stuff on that card, is their any way format it, or repair the partition table, so I can at least attempt to recover the data?

Why are you trying to format it if you want to recover data??? Formatting will erase any data on the card –  Sergey Oct 17 '12 at 3:53
    
I figured if I could not rebuild the part. table, maybe I could format it, and use a data recovery program such as photorec to see if anything was left. As of now it's unreadable, so the data recovery programs don't even make an attempt. –  David matthews Oct 17 '12 at 4:17
    
Formatting the card will surely destroy (or have destroyed already) your last chance to recover the data. First thing you need to do is to make a binary dump of the card and work with that without touching the card. It doesn't look too promising at any rate - hardware reports the card being 32Mb instead of 32Gb... which probably means the card reports itself as being 32Mb... which suggests that it's dead, Jim. –  Sergey Oct 17 '12 at 4:49
