Little warning: USB is broken: USB 2.0/3.0 doesn't work on USB 1.0
Maybe it's scsi protocol on top of it, or something microsoft specific ?
You know anything about that ?! SCSI CDBs (Control and Data Blocks) is the Microsoft method for anything "foreign". OK Very nice ! You continue to amaze me with your knowledge or knowledge finding skills ! =D I did a sniff with wireshark and usbcap and there indeed seems to be some SCSI CDB involved. And this link learns me mo https://en.wikipedia.org/wiki/SCSI_command In the bottom is a SCSI commands reference manual: https://www.seagate.com/files/static...100293068j.pdf Linking to this PDF, first time I tried to download it, somehow an 404 error, but second time it worked. At page 37 it starts explaining CDB. At the next page I can already see how this is probably working. There are 8 bytes for a logical block address. So apperently this technology is at least 64 bit, and can probably at least achieve 2^64 file sizes, so that's roughly 16 exabyte if I recall correctly, probably a bit larger if multiplied by sector or max block size or whatever the "grain size" is So this is somewhat re-assuring and amazing, so basically these old systems should be able to "scale up" and use super large harddisks, now and in the future, any device basically that can use USB and SCSI CDB, so that is pretty amazing ! Bye for now, Skybuck. |

Oh now that I take a closer look at that table and read page 43 where logical block address is explained.
The previous tables 2,3,4 and such work as follows: Horizontally bits Vertically bytes. However Table 5 shows the 16 byte command. Byte 2 to byte 9 being the logical block address. (9-2)+1 = 8 bytes for addressing, so it's still 64 bit. If this 16 byt command is supported and probably is in hardware and software, so this is quite cool =D Though this is an assumption for now =D Bye, Skybuck =D |

I checked in wireshark/sniffer and SCSI is indeed being used and the Logical Block Addresses are indeed 64 bits.
Big SMILE =D thanks to BIG NUMBERS LOL ! =D Bye, Skybuck =D |

One more thing, there are different wiki's, this one has even more/better story/information, explaining how it works basically:

https://en.wikipedia.org/wiki/Libguestfs
I don't think this can work on my DreamPC cpu which is this one (manchester): http://www.cpu-world.com/CPUs/K8/AMD...800BVBOX).html This libguestfs is a KVM module for Linux at least so the wiki says Then this links states what is needed for KVM: http://www.linux-kvm.org/page/FAQ#Wh..._to_use_KVM.3F " What do I need to use KVM? You will need an x86 machine running a recent Linux kernel on an Intel processor with VT (virtualization technology) extensions, or an AMD processor with SVM extensions (also called AMD-V). Xen has a complete list of compatible processors. For Intel processors, see also the IntelĀ® Virtualization Technology List. " However maybe I mis-interpret this because the next paragraph reads: " Are 64-bit processors supported under KVM? Yes they are supported and will allow you to run 32-bit and 64-bit guests. See also Can KVM run a 32-bit guest on a 64-bit host? What about PAE? below.. " However the rest of the page goes on about AMD-V and such. So little bit confused if it will work,but for now my hunch is probably not, unless there is some software emulation or exception for 64 bit processor, but I don't think this is going to work And that makes this option useless for me and my older computers Very maybe toshiba laptop has support for this, icore5 maybe ? Hmmm don't know. I think this is a bad idea to have a solution that requires specialized instructions and does not support general/generic instructions. Bye for now, Skybuck. |
