Method for storing HDD critical data in flash
InactiveUS20050125600A1Eliminate timeShorten the timeEnergy efficient ICTRecord information storageTime criticalData access
A method for retrieving critical data that is determined to very likely be requested by a host device in the near future and storing it in FLASH. The hard drive provides the critical data to the requesting host upon receiving the request, thereby eliminating the time required to respond to the request due to media accessing. The critical data may be related to power-on of the computer, such as boot sector FAT system data. The critical data maybe re-allocated and placed in sequential order, thereby saving time from seeking to different locations over the media. Critical data may stored in FLASH memory, providing quicker data access while consuming less power. While the hard drive is in low power states, other data can be written to FLASH in order to conserve energy.

A method for automatically updating and backing up the BIOS in data processing devices is prsented. Via a wireless transmission device installed in it, a data processing device receives a BIOS files from an electronic device, and then checks the file's ID code to see if it is correct and is of a latest version. If the BIOS file is correct and is of a latest version, the data processing device will save that BIOS file to its boot up sector and then restart the system to see if the updated BIOS can activate the system in normal working conditions. If the system can be activated, then the BIOS file at the backup sector will also be updated. If the system cannot be activated in normal working conditions, then the BIOS source codes at the backup sector will be copied to the boot sector in order to salvage the BIOS file.

Converting file-systems that organize and store data for computing systems
ActiveUS20070112891A1Efficient implementationReduce in quantityDigital data information retrievalDigital data processing detailsFile systemBoot sector
Techniques for converting file-systems used for organizing and storing data on computer readable mediums are disclosed. A first file-system is converted to a second file-system while file(s) stored on the computer readable medium remain(s) virtually undisturbed in the same location. A FAT file-system (e.g., FAT32) is converted to an HFS file-system (e.g., HFS Plus) by generating HFS data structures (Catalog, Allocation File and Extents) for file(s) already stored in the HFS file-system. The number and location of the file(s) can be determined primarily based on the FAT file-system's data structures (FAT and Directory). The conversion process can be stopped before the FAT file-system indicators (partition map and boot sector) are overwritten. After the HFS data structured have been generated and successfully verified for the file(s) already stored on the computer readable medium, the HFS file-system can effectively replace the FAT file-system by modifying the partition map and writing a volume header that may overwrite that boot sector. Similarly, A HFS file-system can be converted to a FAT. In general, any file-system used to organize and store files can be converted based on the location of the files(s) which is typically readily obtainable from the original file-system.

In a disc drive data storage area of sectors, user spare sectors are located not at the end of a track, a cylinder, or a segment but at the end of the data storage area. Any defective user data sector is slipped to the next closest good sector over the full volume of the data storage area. That is, the data that would have been stored in the defective sector is pushed down to the next good sector, as each of the subsequent sectors are slipped sequentially to the next good sector in the full volume of the data storage area. A user sector slip list is generated to access the full volume slipped data storage area. Newly-identified defective sectors are redirected to good sectors in reserve data area in the data storage area of sectors. An alternate sector list is maintained to facilitate an access to a redirected reserve data area.
