Bug 17671 – dosfsck from dosfstools-2.8-r3 cannot fix bad clusters on FAT floppies when they occur in files.

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Aniruddha Shankar 2003-03-17 04:36:28 UTC]

> dosfsck -waft /dev/fd0
dosfsck 2.8, 28 Feb 2001, FAT32, LFN
/Notice-appli.doc
  Cluster 7 (9) is unreadable. Skipping it.
Internal error: next_cluster on bad cluster
>

When dosfsck finds bad clusters in files on FAT floppies, it borks and returns to the prompt. To mark bad clusters on FAT floppies you have to format the floppy first or delete all the files and then, immediately afterwards, run dosfsck .

Reproducible: Always
Steps to Reproduce:
1. fill an entire FAT floppy with files.
2. punch a  hole in the floppy material with a pin or scissor tip
3. run dosfsck -waft /dev/fd0, which should check the floppy for physical errors. 
Actual Results:  
dosfsck, on encountering an error in a file will crash to the command prompt. 

Expected Results:  
dosfsck should mark the affected clusters as bad in the FAT and continue checking from the next cluster onwards.

i'm in london ... currently i'm an inactive dev ...

but is this *really* a Gentoo bug ?

[Comment 2 Aniruddha Shankar 2003-04-29 17:21:48 UTC]

I'm not sure it is a gentoo bug. I don't run any other version of linux so am unable to check. is it possible for you to do this ? shouldn't take much time, as long as you have access to a machine running a distro other than gentoo.

this does seem to be gentoo specific.

won't fix.

correct to my faulty typing above...  :(

this *DOES NOT* seem to be Gentoo specific...

won't fix...
