Thread: How to reduce the size of a gmapsupp.img file on a card???

Continuing the interesting and important OT, I agree it's always wise to properly check the real capacity of any card particularly if from a source like ebay or ali. Like you I got an unbranded SDHC, purported to be 8GB but was only 2GB. I used H2testw and then sent the report and demanded a refund. The seller in China said to send it back, I said fine if you pay return postage or I'll open a dispute so he said ok keep it and refunded me. I recovered it with HDD LLF Low Level Format Tool as a 2GB card.

It's flaky as all getout tho' and really not usable.

Another limiting factor not widely known is the wear leveling built into flash memory. Slows down the older more used cards.
