Your card just stays busy and times out.
Hot InsertionSupport for hot insertion will be required on the host but will be supported through theconnector. Connector manufacturers will provide connectors that have power-pins longenough to be powered before contact is made with the other pins. This approach is similarto that used in PCMCIA and MMCA devices to allow for hot insertion.
Physical Layer Specification Version 3.006.1 Hot Insertion and RemovalTo guarantee the proper sequence of card pin connection during hot insertion, the use of either a special hot-insertion capable card connector or an auto-detect loop on the host side (or some similar mechanism) is mandatory (Refer to the Mechanical Addenda).No card shall be damaged by inserting or removing a card into the SD Memory Card bus even when the power (VDD) is up. Data transfer operations are protected by CRC codes, therefore any bit changes induced by card insertion and removal can be detected by the host.The inserted card shall be properly reset also when CLK carries a clock frequency Each card shall have power protection to prevent card (and host) damage. Data transfer failures induced by removal/insertion are detected by the host. They should be corrected by the application, which may repeat the issued command.
Hot Insertion/RemovalHot insertion and removal are allowed. The SanDisk SD Card will not be damaged by inserting or removing it into the SD bus even when the power is up:• The inserted card will be properly reset also when CLK carries a clock frequency fPP.• Data transfer failures induced by removal/insertion should be detected by the bus master using the CRC codes that suffix every bus transaction.3.2.1. Power ProtectionCards can be inserted into or removed from the bus without damage. If one of the supply pins (VDD or VSS) is not connected properly, then the current is drawn through a data line to supply the card.Data transfer operations are protected by CRC codes; therefore, any bit changes induced by card insertion and removal can be detected by the SD bus master. The inserted card must be properly reset also when CLK carries a clock frequency fpp. If the hot insertion feature is implemented in the host, than the host has to withstand a shortcut between VDD and VSS without damage.
