9. A system comprising:
(a) a data storage device including:
(i) a NAND flash memory,
(ii) an executable interface that supports a first protocol, and
(iii) a controller for receiving, via said executable interface, an instruction to access said NAND flash memory at a virtual address, and for translating said virtual address to a physical address in said NAND flash memory; and
(b) a host, of said data storage device, that is operative to issue said instruction by executing a driver of said data storage device that emulates a second protocol different from said first protocol.
10. The system of claim 9, wherein said second protocol is a protocol of a nonexecutable interface.
11. The system of claim 10, wherein said nonexecutable interface is a USB interface.
12. The system of claim 10, wherein said nonexecutable interface is a SD interface.
13. The system of claim 10, wherein said nonexecutable interface is a MMC interface.

The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
I claim:
1. The combination of a removable sewer basket with a sewer basket support for retaining said basket at a selected level within a vertical sewer pipe having an interior surface and an opening at street level, said basket including a plurality of filter units, each one of said filter units having a frame and a filter screen secured to and closing said frame, said basket support being adapted for fixing to said interior surface of said sewer pipe at the selected level below street level, and a plurality of handle devices accessible at said street level to position and place a respective one of said filter units on and to retrieve said filter units from said basket support, said filter units adjacently and releasably resting on said basket support.
2. The combination as defined in claim 1, wherein said basket support being expandable and having at least one pair of opposite spaced free ends, an adjustable expansion device joining said opposite ends to expand said basket support against said interior surface of said sewer pipe and to fix said support to said interior surface at the selected level below street level.
3. The combination as defined in claim 2, wherein said basket support including a frame forming strip, said opposite ends formed by the ends of said strip include inturned perforated ears, and said expansion device includes a bolt extending through and joining said ears and nuts screwed onto said bolts and engaging said ears to spread said ears apart and retain said ears spaced apart from each other.
4. The combination as defined in claim 3, wherein said strip having inwardly directed ears on which said filter units removably rest.
5. The combination as defined in claim 4, wherein said basket support further including an intermediate support releasably resting on said strip, said intermediate support having a substantially flat lattice shape releasably supporting said filter units resting thereon.
6. The combination as defined in claim 1, wherein said opening at street level being of a small size relative to a cross-section of said vertical sewer pipe, each one of said filter units having an overall horizontal dimension so as to get through said opening while being in a substantially horizontal orientation.
7. The combination as defined in claim 1, wherein each one of said frames including a crossbar secured to opposite sections of said frame, each one of said handle devices including a post with a handle at an upper end of said post, a lower end of said post adjustably and releasably attaching to a respective one of said crossbars via a connecting member.
8. The combination as defined in claim 7, wherein each one of said connecting members being substantially located at a center of gravity of a respective one of said filter units.
9. The combination as defined in claim 7, wherein each one of said crossbars being straight and overlies said filter screen.
10. The combination as defined in claim 7, wherein each one of said connecting members being a nut secured to said crossbar, said lower end of said post being externally threaded to releasably and adjustably engage said nut.
