The erase all blocks command can erase multiple blocks (if the device has more than one flash block), but the erase flash block command only erases a single block. If any of the regions within the block are protected, the erase aborts.

However, you can only write to one entire block of cells at a time. Typically these blocks of cells are at least 128KB in size. So suppose you are writing a 4KB file to your SSD. Well, you have to write one 128KB block at a time. dutch medped

WebFeb 1, 2024 · Taking the block out of service would be inefficient and unnecessary. Simply pick another block, copy the data from the old block to the new block, and erase the block that caused the error. It is then ready to return to service. In the case that the erase fails, the result is more severe. WebBlock devices had a fixed size and could be seek-ed. They also happened to be organized in blocks of multiple bytes, usually 512. Flash doesn't match the description of either block or character devices. They behave similar to block device, but have differences.
