I installed flash module (4MB) to Cisco877, then formatted the flash and uploaded IOS version 12.4(11)XJ into the router. After turned off the router more than 1 day, it could not open the boot file. The size of IOS is 0 byte when I typed the command 'dir flash:' in rommon mode. The information below is the error message I got when boot the router.

flashfs[0]: Checking block 151...bad block number (407)

flashfs[0]: erasing block 151...done.

flashfs[0]: Checking block 152...bad checksum (58096 != 53697)

flashfs[0]: erasing block 152...done.

flashfs[0]: inconsistent sector list, fileid 2, parent_fileid 0

flashfs[0]: block 151 not available or in use, state: unknown[0xe].

flash: file system initialization failed

Could not open boot directory: flash:/

Unable to open boot file

Could anyone suggest me what I should do?

Thank you.

Try to upload new IOS using XMODEM this should erase the flase and try initialize it again. if same issue persist it could be a damaged flash and you will need to open a case with Cisco TAC for replacement.

Hope this helps,
