mini sd problems

[Guest Vylle]

yo fine ppl got problems with minisd

i just bought a 1 GB a while ago and stuck it ma phone.. it works perfectly there

however when i stick it into ma computer (which i SUPPOSED to read it) it says that the disk itself is unreadable

but here is the catch.. it works perfectly in other computers.. i tested it in at least 2 different laptops simular to mine and it opens and runs perfectly

furthermore, i put other SD cards in my computer and it runs perfectly.. however, it still won't run the 1 i have

someone please help me out.. what am i supposed to do?
