'Generic Hierarchy' Filesystem Mini Spy. When I browse through the files on her MP3 player in Windows. It's a generic, low end Coby device. I want to format the 32Gb storage to FAT32 but it keeps on formatting to generic hierarchical. I've heard that FAT32 is much better than generic hierarchi.

For example, on a 1 GB disk, the allocation block size under HFS is 16 KB, so even a 1 byte file would take up 16 KB of disk space. This situation was less of a problem for users having large files (such as pictures, databases or audio) because these larger files wasted less space as a percentage of their file size.

The Hierarchical File System groups these logical blocks into allocation blocks, which can contain one or more logical blocks, depending on the total size of the volume. HFS uses a 16-bit value to address allocation blocks, limiting the number of allocation blocks to 65,535 (2 16-1). Five structures make up an HFS volume: • Logical blocks 0 and 1 of the volume are the, which contain system startup information.

FAT12, FAT16 and FAT32 also have a limit of eight characters for the file name, and three characters for the extension (such as ). This is commonly referred to as the limit., an optional extension to FAT12, FAT16 and FAT32, introduced in and, allowed long file names () to be stored in the FAT file system in a backwards compatible fashion. Main article: is a proprietary and patent-protected file system with certain advantages over NTFS with regard to. ExFAT is not backward compatible with FAT file systems such as FAT12, FAT16 or FAT32.

It likely wouldn't stand up to examination, but anyone wanting to take on Microsoft's legal team is welcome to. But I decided to double check and pulled it out and plugged it into a SD slot (doesn't work in my microsd slot too big, I guess?) And yah, there it shows FAT32 But I finally figured out the drivers for my phone or something is the one that labels it 'generic Hierarchical' instead of fat32 You've already said it's not a thing. It's a bad translation on your phone.

It just goes back to the generic hierarchical file system. Another thing I've tried is format it with the Disk Manager and with the Command Prompt (format /FS:FAT32) but since the mp3 isn't a volume or a disk (like C or D) but a Portable Device (as it says in Explorer) it doesn't work. I also tried some formatting software but as in the Disk Manager the mp3 doesn't show because it's a portable device and not a disk. Anyone know how I can solve this?

Tape file systems [ ] A tape file system is a file system and tape format designed to store files on tape in a self-describing form [ ]. Are sequential storage media with significantly longer random data access times than disks, posing challenges to the creation and efficient management of a general-purpose file system.

Seems to be fine they me my phone can only really do class 6. So it's good enough. Is it possible NTFS or another partition might be better and work with android. Or it's just basically fat32 every time? F2FS works very well if your ROM supports it. ExFAT is also very good (but patent encumbered), while ext2/3/4 work well too. The patent (US 8321439) on exFAT seem to have taken even Microsoft by surprise when it was granted, as there isn't anything there that's not obvious or was already happening in CP/M, FAT12/16/32, HPFS or NTFS (prior-art).

Just now I took a 500MB Seagate 'pocket' USB-powered mechanical HDD, formatted it with a single NTFS partition under Windows 7, and then plugged it into my ASUS Transformer Infinity TF700T tablet/netbook. Everything is bone stock; no root kits, no special anything. The big USB drive auto-mounted and showed me files. It's just a basic test, but it shows that at least one Android device can deal with: • USB hard disks with more capacity than any SD card. • Windows partitions including exFAT and NTFS. • Auto recognition and auto mounting of all the above. This is good news because it shows that at least some Android devices come right out of the box with the ability to use media that's thought of as 'computer peripherals'.

Anyone know how I can solve this? Help is appreciated! Worth a read.

Access to a data record requires two levels of, where the file's directory entry (called a File Status Table (FST) entry) points to blocks containing a list of addresses of the individual records. AS/400 file system [ ] Data on the AS/400 and its successors consists of system objects mapped into the system virtual address space in a. Many types of are defined including the directories and files found in other file systems. File objects, along with other types of objects, form the basis of the As/400's support for an integrated. Other file systems [ ] • The Prospero File System is a file system based on the Virtual System Model.

What language is your phone set to? As many other posters have said, Generic hierarchical is not a file system that exists, and it most certainly isn't HFS.

For a 512-byte allocation, the average unused space is 256 bytes. For 64 KB clusters, the average unused space is 32 KB. The size of the allocation unit is chosen when the file system is created. Choosing the allocation size based on the average size of the files expected to be in the file system can minimize the amount of unusable space. Frequently the default allocation may provide reasonable usage. Choosing an allocation size that is too small results in excessive overhead if the file system will contain mostly very large files.

It stores four types of records. Each file consists of a File Thread Record and a File Record while each directory consists of a Directory Thread Record and a Directory Record.

When the system needed to read data, the user was instructed to press 'PLAY' on the cassette recorder. The system would listen to the sounds on the tape waiting until a burst of sound could be recognized as the synchronization. The system would then interpret subsequent sounds as data. When the data read was complete, the system would notify the user to press 'STOP' on the cassette recorder. It was primitive, but it worked (a lot of the time). Data was stored sequentially, usually in an unnamed format, although some systems (such as the series of computers) did allow the files to be named. Multiple sets of data could be written and located by fast-forwarding the tape and observing at the tape counter to find the approximate start of the next data region on the tape.

For example, the names of the System and Shell (usually the ) files which are loaded at startup. • Logical block 2 contains the Master Directory Block (aka MDB). This defines a wide variety of data about the volume itself, for example date & time stamps for when the volume was created, the location of the other volume structures such as the Volume Bitmap or the size of logical structures such as allocation blocks. There is also a duplicate of the MDB called the Alternate Master Directory Block (aka Alternate MDB) located at the opposite end of the volume in the second to last logical block.

4 gb+ file sizes. It's not worth the hassle. I would think with the continued increase spec's of these smartphones. At some point were gonna have to see that fixed. Or maybe exfat does that.?

This worked well with a system with a few hundred kilobytes of storage and perhaps a hundred files, but as the systems grew into megabytes and thousands of files, the performance degraded rapidly. The solution was to replace MFS's directory structure with one more suitable to larger file systems. HFS replaced the flat table structure with the Catalog File which uses a structure that could be searched very quickly regardless of size. HFS also re-designed various structures to be able to hold larger numbers, 16-bit integers being replaced by 32-bit almost universally.

• A Directory Thread Record stores just the name of the directory and the CNID of its parent directory. • A Directory Record which stores data like the number of files stored within the directory, the CNID of the directory, three timestamps (when the directory was created, last modified, last backed up). Like the File Record, the Directory Record also stores two 16 byte fields for use by the Finder.

Hello, I just found my old Samsung K5 (mp3 player) and after a bunch of attempts trying to upgrade the firmware I couldn't copy any files to the mp3, neither from the explorer nor from Samsung's software. Somehow the mp3 was formatted to a file system called generic hierarchical and I assume that is why i can't copy any files because before, when it was formatted with FAT32, I didn't have any trouble copying files. Therefore I want to reformat the mp3 back to FAT32. I've tried right clicking the samsung mp3 icon in explorer and hit format and I've also tried format it with Samsung's software without any succeed.

Android Generic Hierarchical File System

• Logical block 2 contains the Master Directory Block (aka MDB). This defines a wide variety of data about the volume itself, for example date & time stamps for when the volume was created, the location of the other volume structures such as the Volume Bitmap or the size of logical structures such as allocation blocks. There is also a duplicate of the MDB called the Alternate Master Directory Block (aka Alternate MDB) located at the opposite end of the volume in the second to last logical block. This is intended mainly for use by disk utilities and is only updated when either the Catalog File or Extents Overflow File grow in size. • Logical block 3 is the starting block of the Volume Bitmap, which keeps track of which allocation blocks are in use and which are free. Each allocation block on the volume is represented by a bit in the map: if the bit is set then the block is in use; if it is clear then the block is free to be used.

When disks were small, this was of little consequence, because the individual allocation block size was trivial, but as disks started to approach the 1 GB mark, the smallest amount of space that any file could occupy (a single allocation block) became excessively large, wasting significant amounts of disk space. For example, on a 1 GB disk, the allocation block size under HFS is 16 KB, so even a 1 byte file would take up 16 KB of disk space.

The file system is supported with newer Windows systems, such as Windows Server 2003, Windows Vista, Windows 2008, Windows 7, Windows 8, and more recently, support has been added for Windows XP. ExFAT is supported in macOS starting with version 10.6.5 (Snow Leopard). Support in other operating systems is sparse since Microsoft has not published the specifications of the file system and implementing support for exFAT requires a license. ExFAT is the only file system that is fully supported on both macOS and Windows that can hold files larger than 4 GB. [ ] OpenVMS [ ]. Main article: Prior to the introduction of, systems implemented an unusual hybrid file system. The system was designed to easily support, so the information relating to all files on one disk ( volume in IBM terminology) is stored on that disk in a called the (VTOC).
