Hi, older Cisco 4500 series supervisor engines support compact flash cards. However, Cisco-branded 32MB compact-flash taken from Cisco 1800 series router is not recognized by SUP:
Catalyst4500#dir slot0: %Error opening slot0:/ (Bad device info block) Catalyst4500# After executing "format slot0:", the compact flash became accessible: Catalyst4500#format slot0: Format operation may take a while. Continue? [confirm] Format operation will destroy all data in "slot0:". Continue? [confirm] Enter volume ID (up to 64 chars)[default slot0]: Format of slot0 complete Catalyst4500#dir slot0: Directory of slot0:/ No files in directory 31784960 bytes total (31784960 bytes free) Catalyst4500# The problem is, that now I'm not able to access this compact-flash in my PC. Looks like it even does not have a partition-table: T42 ~ # dmesg | tail [1983944.880491] ata5.00: 62720 sectors, multi 0: LBA [1983944.888476] ata5.00: configured for PIO0 [1983944.888794] scsi 4:0:0:0: Direct-Access ATA STI Flash 8.0.0 01/1 PQ: 0 ANSI: 5 [1983944.889398] sd 4:0:0:0: Attached scsi generic sg2 type 0 [1983944.891205] sd 4:0:0:0: [sdb] 62720 512-byte logical blocks: (32.1 MB/30.6 MiB) [1983944.891403] sd 4:0:0:0: [sdb] Write Protect is off [1983944.891414] sd 4:0:0:0: [sdb] Mode Sense: 00 3a 00 00 [1983944.891501] sd 4:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [1983944.910031] sdb: unknown partition table [1983944.910632] sd 4:0:0:0: [sdb] Attached SCSI removable disk T42 ~ # fdisk -lu /dev/sdb Disk /dev/sdb: 32 MB, 32112640 bytes 255 heads, 63 sectors/track, 3 cylinders, total 62720 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table T42 ~ # file -s /dev/sdb /dev/sdb: data T42 ~ # dd if=/dev/sdb bs=512 count=1 | hexdump -C 00000000 88 06 35 76 ea 01 00 00 01 00 00 00 00 00 04 00 |..5v............| 00000010 ff ff ff ff 01 00 06 00 03 00 00 00 e5 01 00 00 |................| 00000020 00 00 00 01 02 00 7c 60 00 00 00 00 02 00 c2 ff |......|`........| 00000030 00 00 3e 00 e8 01 00 00 01 00 00 00 e9 01 00 00 |..>.............| 00000040 01 00 00 00 6c 73 74 6f 00 30 00 00 00 00 00 00 |....lsto.0......| 00000050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 000000a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 |................| 000000b0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00000100 d0 ba 1e 0b 02 00 f8 5f b8 80 ff ff ff ff ff ff |......._........| 00000110 6f 79 61 64 66 2d 6c 73 62 69 6d 2d 00 00 00 00 |oyadf-lsbim-....| 00000120 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000140 45 7f 46 4c 02 01 00 01 00 00 00 00 00 00 00 00 |E.FL............| 00000150 02 00 70 00 00 00 01 00 00 01 00 00 00 00 34 00 |..p...........4.| 00000160 02 00 68 5e 00 00 00 00 34 00 20 00 01 00 28 00 |..h^....4. ...(.| 00000170 0a 00 09 00 00 00 01 00 01 00 00 00 00 01 00 00 |................| 00000180 00 01 00 00 01 00 b4 57 29 00 a4 c2 00 00 07 00 |.......W).......| 00000190 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 000001a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 1+0 records in 1+0 records out 512 bytes (512 B) copied, 0.0158727 s, 32.3 kB/s 00000200 T42 ~ # "format" command creates a "Class A" file-system?
