![]() ![]() would be good if Easeus did not cripple their ext* support by binding itself to obsolete x86 linux and its crippled e2fsprogs. Partition Magic 8 does handle larger ext2 block sizes but is not compatible with modern windows. The ext* spec easily allows upto 64Kbyte block sizes and many embeded systems do use the larger block sizes to reduce the tendancy for files to fragment and reduce the DMA/interupt overheads by reading and writing bigger chunks at a time. One shortfall of easeus partion master ext2/3 handling is it only recognises a small subset of the ext* specification and marks partitions intended for ia64 arcitecture or embedded linux NAS/PVR's etc that use block sizes greater than x86 linux ext* 4kbyte limit due to linux inability to work around the 4k page memory mapping it does that only x86 linux has problems with. This means when a sector fails there is usually no way to get the good data back if the sector is in a critical structure, it will spot an inconsistancy flag the file system as bad and force a fschk on next boot and if it does come up bad it will just demand the drive needs to be reformated causing the loss of hundreds of gigabytes of data, easus *could* solve those problems if only it relied on complete ext* file system drivers without the linux x86 4kblock limit! People with these embeded systems are held captive by whatever the limitations are of the embeded firmware and in many cases it does not include a file system repair tool or defragmenting tool or ability to format a file system beyond the original models designed largest fitted hard drive. ![]()
