Maybe the NAS does not allow (or not easily) reading from snapshots blocks that were never written to? Does it have its own log? Anything interesting in it? Did you try reading from the disk directly (e.g. with dd)? Does it work? The only FS errors misreported as I/O errors I have seen are with corrupted FSes that had (bad) pointers to non-existing sectors. The sector numbers in your case are small so I do not think that's the case. > * the kernel, although newer (2.4.18 IIRC) is still too old for this > (odd?) I have no idea. My wild guess is that it's irrelevant of kernel version, as long as the driver is good and is compatible with the kernel. -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
