Can't find the meaning of the time, unc, abrt, idnf, amnf, tonf, and bbk. Is this documented anywhere? Are all of these equally bad? Can I run scan with remap and use arrow keys to unhcr go to the bad areas and just fix these few errors?

(TONF) Track 0 Not uncrc Found: Track 0 was not found during drive recalibration. (ABRT) Aborted Command: The requested command was aborted due to a device status error. (IDNF) ID Not Found: The required cylinder, head, and sector could not be found, or an ECC error occurred in the ID field. (UNC) Uncorrectable Data: An ECC error in the data field could not be corrected (a media error or read instability). (BBK) Bad Mark Block: A bad sector mark was found in the ID field of the sector or an Interface CRC error occurred.

One other question that it didn't answer, is there a way to see the current set of remapped sectors? I was able to remap the two unc's I had and perhaps my drive will work ok now. I had a strange problem. Somehow while doing only a read of the drive (under windows 2k) it wiped out the signature at the end of the mbr, but NOT the partition table. It thought the device was no longer valid. But I used a disk editor (winhex) to repair those 2 bytes and everything came
disk imaging, the second phase in the 3D Data Recovery process. Traditional disk imaging methods are time-consuming and don’t always yield usable data, because of read instability and the constraints

of system software. DeepSpar Disk Imager overcomes these challenges, efficiently retrieving data from bad sectors and reducing the risk of disk failure. Data recovery firms can handle more cases and retrieve more data by going deeper during this data recovery phase. Introduction Data recovery firms are missing out on data they could retrieve with the complete 3D Data Recovery process. Proper http://forum.hddguru.com/viewtopic.php?t=6992&start= data recovery involves three phases: drive restoration, disk imaging, and data retrieval. But data recovery professionals can face frustrating problems when imaging a damaged disk. The drive may repeatedly stop responding in the middle of copying data. The drive may fail completely because of the stress caused by intensive read processes. Significant portions of data may be left behind in bad sectors. http://www.deepspar.com/wp.html These issues plague firms that use traditional disk imaging methods. Read instability makes it difficult to obtain consistent data quickly, and system software is not equipped to read bad sectors. However, these problems can be solved with imaging tools that address disk-level issues. Imaging software bypasses system software and ignores error correction code (ECC), processing each byte of data in bad sectors. Inconsistent data is evaluated statistically to determine the most likely correct value. Faster transfer methods speed up the process, and customizable algorithms allow the data recovery professional to fine-tune each pass. Imaging software provides feedback on the data recovered while imaging is still underway. Imaging hardware can reset the drive when it stops responding, which minimizes damage from head-clicks and allows the process to run safely without supervision. DeepSpar Disk Imager incorporates all of these methods, enabling firms to recover more data from previously inaccessible drives, and significantly reducing the imaging time required. 1.

Ubuntu is installed on the Primary, which runs perfectly. However when the second hard drive is connected Ubuntu won't boot. I get an error screen which reads: [272.854943] ata2.00: status: {DRDY err} [xxx.xxxxxx] ata2.00: error: {UNC} [xxx.xxxxxx]ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 [xxx.xxxxxx] ata2.00: BMDMA stat 0x24 [xxx.xxxxxx] ata2.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 dma 4096 in the x's are all different numbers. The message repeats several times. Sometimes it says Buffer I/O error on device sdb1, logical block x (where x is a changing number) In the forum a similar question has been asked before by others, but not answered. I have tried switching the cables, the result was the same as before. Since I can't get Ubuntu to boot with the second drive connected I can't use any tools to analyse or fix
