Write Long (10)
The Write Long command allows for Error Correcting Code (ECC). The data sent from the initiator will include ECC fields as well as real data. The Byte Transfer Length field tells the target how much data will need to be returned when the data is subsequently retrieved with a Read Long command. The CDB structure is:
bit→ ↓byte |
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
---|---|---|---|---|---|---|---|---|
0 | Operation code = 3Fh | |||||||
1 | COR_DIS | WR_UNCOR | PBLOCK | Reserved | Obsolete | |||
2 | LBA | |||||||
3 | ||||||||

Famous quotes containing the words write and/or long:
“Anyone can see that to write Uncle Toms Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.”
—Anna Garlin Spencer (18511931)
“Age is not a particularly interesting subject. Anyone can get old. All you have to do is live long enough.”
—Groucho Marx (18951977)
