Krabicka pro pripojeni notebookoveho harddisku (2.5") na USB sbernici. USB 1.1. Pokud disku nestaci napajeni dodane USB sbernici, lze pripojit externi napajeni z PS2 konektoru pro klavesnici.

V mem pripade se jedna o krabicku pre notebookovy harddisk. Ale tento chip se pouziva take ve velkem mnozstvi externich boxu pro ATAPI periferie jako treba CD-ROM, CD-RW, ZIP a 3.5" harddisky.

Identifikace pod Linuxem

verze se starym firmwarem, pod Linuxem NEFUNGUJE!! Vsimnete si polozky "bcdDevice".

Postup zprovoznění pod Linuxem

Chip ScanDisk SL11R-IDE funguje s Linuxem pouze s nejnovejsim firmwarem. V mem pripade mi externi disk zacal fungovat teprve po upgrade firmwaru z verze 2.60 na 2.6c. Upgrade se musi provest ve Win98, firmware se stahne z webu firmy Cypress (koupil firmu ScanLogic):
http://www.cypress.com/cfuploads/support/reference_design/C700C418-E43B-4165-B41C924687ED5001_soft_1.zip
(Support: Reference Designs: USB Full-Speed Peripherals : SL11RIDE-DK)
Balik se nainstaluje pod Windows, pak se spousti USB2IDE (V Start menu) a ten preflashuje firmware. Process neni uplne trivialni, ale zkusenejsi uzivatel se znalosti anglictiny by to mel zvladnout.

modul: usb-storage

mount /dev/sda1 /mnt/disk

Poznámka

Dejte si pozor, aby vas hardisk nemel spotrebu vetsi nez 0.5A, protoze jinak budete muset pouzivat externi zdroj. Notebookove hardisky majici spotrebu do 0,5A vyrabi napriklad Hitachi a IBM, harddisky Toshiba uvadeji spotrebu 0.7A! (Spotreba byva uvedena na harddisku). Elegantni reseni jak mit 1-20GB prenosny harddisk, idealni na pro zalohovani a prenosy dat.

Bohuzel, nevim jak lze pod Linuxem disk rozdelit a naformatovat pro prvni pouziti...

Testovano s MDK 8.2, kernel 2.4.18mdk
