- I've come across what looks to me like a bug, possibly in the msdos
- FS. My setup is a 386SX-20 with an IDE disk and a HP7959S (Imprimis
- 97536) external SCSI disk using an Adaptec 1540B. I run Linux 0.99.2
- on the SCSI disk, which also has a 20Mb DOS partition.
-
- After reformatting the SCSI disk last week I untar'd the whole lot
- from backup tape (btw, Archive Viper 2150S's seem to work OK with the
- generic SCSI tape driver!) including the DOS partition, which I have
- mounted as /dos. However, the DOS partition was mangled after I
- restored it. I've tried cp-ing between extfs and msdos fs's and tar
- xvf-ing from both (and tape), and the same things happen.
-
- What seems to be happening is random files and subdirectories get
- extra chunks (in the case of files, blocks of 248 0x00 or 0xff bytes,
- and the case of directories, about the same amount of garbage)
- inserted (ie, not overwritten) into them in random places (frequently
- at the beginning though). It may be some sort of race condition -
- single small files seem OK, but untarring lots of directories and
- small files or copying one big one isn't.
-
- Running the 0.98.1 kernel, I don't get any problems. I haven't been
- able to reproduce it on my IDE disk, but I haven't tried too hard
- because I don't have any spare partitions to trash 8^)
-
- Has anybody experienced this before or is it just me? - I haven't seen
- anything like it reported on c.o.l recently and the msdos fs alpha 9
- release notes didn't mention major bugfixes which sounded relevant to
- this.
