I am marked down as one of the university geeks, and it is coming around to cannot copy data error cyclic redundancy check dvd the time to hand in essays/dissertations etc. Many people have put misplaced faith in the reliability of floppy disks. Is there any tool for linux, which will allow me to ask the floppy driver

in the kernel to keep trying, so I can put together the statistically "best" hex dumps,or extract raw text from Word docs etc. [Dan] 'Fraid I can't offer any way to recover the data once it's lost to bad sectors, tho no doubt some way is possible. Instead I'd like to offer the format script I use for floppies before I'll trust 'em with my data. It culls out jfilerecovery a lot of floppies, and I find that floppies which once passed, after sitting a few years on the shelf, will often no longer do so. User who runs this must have write permission to /dev/fd0h1440. Requires mtools. Watch out, some distributions may obsolete fdformat in favor of superformat. See attached goodfloppy.sh.txt Today I resuced a 6 page essay 10hrs before it was due, [Heather] The easiest way to do this sort of thing (I used to do it too) is 1. use dd to extract a raw image of floppy disks. This is sufficiently reliable that it's now the normal way I mount floppies on my laptop. dd if=/dev/fd0 of=/usr/local/floppy/student-name-ddmmyy.144 bs=18k In case you're curious 18k is the standard blocksize of a single track, so this is the "native" amount of bits the floppy read heads want to read anyway. It should be fastest and have the best chance of getting all the rescuable bits. I already take a copy, as I am not the only geek with enough time, and I don't want to write anything back to a damaged floppy. Thanks for the advice with bs=18k I will use that next time. [Heather] Yep, it's about 8 times faster with that s

copy bad disk Outlook started acting up, so as part of my attempts to fix it I tried to copy the PST to another location. The copy failed part way through with a cyclic redundancy check http://www.tldp.org/LDP/LG/issue77/tag/1.html error. How can I get past this and backup my data? The cyclic redundancy check, or "CRC" error, indicates a bad spot on your hard drive. The fact that you're seeing it when you try to copy a file indicates that the bad spot may be within the file itself. We need to verify that and then we need to try to recovery your https://askleo.com/how_do_i_fix_a_cyclic_redundancy_check_error_when_i_try_to_copy_a_file/ file and repair your hard drive. First, let's make sure that the problem is actually with the file you're copying since it's equally likely that the problem is with the location you're copying too. This is easy. Fire up a Command Prompt window, and then copy the file to NUL: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:>CD (to wherever the file is located) C:wherever>copy Outlook.pst NUL 1 file(s) copied. This reads the entire file by copying it "nowhere". If this succeeds, the problem is not actually with the file itself, but the location you were trying to copy it to. My recommendation would be to copy it to a different disk entirely, or a different machine on your local network. If this copy fails, then we've confirmed that the bad sector on your hard disk is actually being used by some portion of your file. • Now that we've confirmed that the problem is in fact in the file itself, we need to make as best a copy of it as we can, somewhere else. This sets a position of "it can't get any worse than this". Some dataHelp Rules Groups Blogs What's New?
