First, is that in the existing mt man page in the list of density codes, note #3 at the bottom that refers to " 3. Old format known as QIC-11." is not mentioned above. It needs to be on this line: 0x05 6.3 (0.25) 4/9 315 (8,000) GCR C X3.136-1986 1 in the notes column. The second thing is I made up this tape cartridges table that I would like to see added to the "mt page" it is here: NOTE ON QIC STREAMERS The following is a table of Data Cartridge types as used in the 1/4 inch tape drives such as the Archive Viper 150, Wangtek 5525ES, and Tandberg TDC4220 tape drives: Density Code Reference Format Cartridge Type Capacity Tracks Length ------------ --------- ------ -------------- -------- ------ --------- 0x05 QIC-11 DC300 15MB 4 300ft 0x05 QIC-11 DC300XL/P 20MB 4 450ft 0x05 QIC-11 DC600 27MB 4 600ft 0x05 X3.136-1986 QIC-24 DC615A 15MB 9 150ft 0x05 X3.136-1986 QIC-24 DC300XL/P 45MB 9 450ft 0x05 X3.136-1986 QIC-24 DC600A 60MB 9 600ft 0x0F QIC-120 QIC-120 DC600A/DC6150 120MB 15 620ft 0x10 QIC-150 QIC-150 DC600XTD/DC6150 150MB 18 620ft 0x10 QIC-150 QIC-150 DC6250 250MB 18 1,020ft 0x11 QIC-320 QIC-525 DC6320 320MB 26 620ft 0x11 QIC-320 QIC-525 DC6525 525MB 26 1,020ft 0x1E QIC-1000C QIC-1000 DC9100/DL9135 1.0GB 30 760ft 0x1E QIC-1000C QIC-1000 DC9150 1.2GB 30 950ft 0x22 QIC-2GB(C) QIC-2GB DC9200 2.0GB 42 950ft 0x22 QIC-2GB(C) QIC-2GB DC9250 2.5GB 42 1,200ft Notes: QIC-24, QIC-120, QIC-150 use fixed blocksize of 512 bytes, QIC-525, QIC-1000 and QIC-2GB can use blocksize of 1,024 bytes. DDS (DAT) drives generally use variable blocks. QIC-02 and QIC-36 are interface standards for tape drives. The QIC-02 and QIC-36 streamers such as the Wangtek 5250EQ are otherwise identical to their SCSI versions (ie: Wangtek 5250ES). It seems that the 150MB and larger streamers cannot write QIC-24 9 track formats, only read them. DC600A cartridges marked "10,000ftpi" can only be used as QIC-11, QIC-24, and QIC-120 format. DC600A cartridges marked 12,500ftpi can be used as both QIC-120 and QIC-150 format Some manufacturers don't use "DC" on their cartridges. Verbatim uses DL, Maxell uses MC, Sony uses QD, Quill uses DQ. 3M/Imation & Fuji use DC. Thus a DL6250, MC-6250, QD6250, DQ6250 are all identical media to a DC6250. QIC tape media is not "connected" to the take up reels and will de-spool if the tape drive has dust covering the light sensor that looks for the end of tape holes in the media. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
